On June 12, according to a report by the US “Defense World”, Turkish Aerospace Industries (TAI) President Thamel Kothier said that Turkey is stepping up the development of the fifth-generation stealth fighter TF-X. The current development of this fighter Work is going very smoothly, and the first prototype will fly for the first time in 2023. After the United States kicked Turkey out of the F-35 project, Turkey has increased the research and development of the TF-X project and invited many international companies to participate in the research and development, and Pakistan is also interested in partnering with Turkey.

Previously, Turkey’s insistence on purchasing Russia’s S-400 air defense system led to extreme deterioration in its relations with the United States. Therefore, the United States seized the F-35 fighter jets ordered by Turkey and refused to return the deposit paid by Turkey. The United States also imposed sanctions on Turkey and stopped paying Turkey sells various military equipment. In addition, in order to retaliate against Turkey, the United States also intends to sell F-35 fighter jets to Turkey’s opponent Greece, so that Turkey will lose air supremacy in the Aegean Sea. Greece has already ordered French Rafale fighters. If the Turkish Air Force is not equipped with new fighters, it will soon fall into a disadvantage.

Turkey claims that the TF-X fighter jet is composed of approximately 20,000 parts. The production of most of the parts will be completed by the end of 2022. Among them, the most difficult to process is the titanium alloy parts for the engine. However, the Turkish Aerospace Industry Corporation has produced a large number of F- 16 fighter jets, with rich manufacturing experience in such parts. In addition, Turkey is also preparing to cooperate with a Ukrainian company to produce hydraulic transmission mechanisms that control the wing surfaces. The Turkish company Aselsan will be responsible for the avionics equipment of the TF-X fighter, and Havelsan will be responsible for the development of flight control software.

However, if Turkey’s TF-X fighter wants to be successfully developed, it is still facing engine problems. If there is no available engine, the first flight of the TF-X fighter will be impossible to talk about. Previously, Turkey’s T-129 gunship used the American CTS800 turboshaft engine. After the United States imposed sanctions on Turkey, the production of the T-129 gunship encountered serious problems and has not been able to be delivered to other customers. Now that Turkey wants to develop a fifth-generation stealth fighter, the engine is still Turkey’s old problem. It will take at least 10 years for any country to develop a reliable turbofan engine from scratch. Therefore, Turkey will temporarily choose to find a temporary engine. “Guest”, Russia’s RD33 engine is one of the potential targets.

For a medium-sized fighter, the 160 kN thrust provided by the two RD33 engines is completely sufficient, and the FC-31 uses a similar engine. However, if TF-X fighters want to achieve supersonic cruise, they need more powerful engines. The current turbofan engines suitable for medium-sized fighters, only the European EJ200 and the American F414 meet the indicators, but Turkey obviously cannot obtain these two models. The engine can only rely on self-developed.

Pakistan has tasted the sweetness of cooperative research and development on the JF-17 fighter, so it is very willing to join Turkey’s TF-X fighter program. Compared with India’s AMCA fighter, Turkey’s TF-X fighter is making faster progress, which means that Pakistan has It may be equipped with fifth-generation fighter jets ahead of India, and for the first time in nearly 50 years, it has achieved an advantage in air force equipment performance.

These are milestones marking the large repair capacity of fighter jets and recognizing the outstanding development of Vietnam’s aviation engineering industry. Su-27 fighter at A32 Factory. In addition, the factory also repaired tens of thousands of spare parts and equipment for the units; produce hundreds of thousands of aviation technical materials. Besides, it also repairs special motorcycles; participate in the repair of weapons of the Air Defense units, Navy. Recently, the High-Tech Center went into operation, marking a great step forward of the unit. From here, A32 Factory can improve repair capacity to regional and international level. The People’s Army newspaper also said that in the past time, the A32 Factory has successfully repaired and put into flight 30 aircraft of all kinds, ensuring good technical indicators and handed over to the units. The factory also replaced 4 oil barrels and repaired and enhanced the Su-30MK2 aircraft fuel system; manufactures 188 fuel pipes, special high-pressure gas pipes, special air defense lights for TZM cars… In addition, A32 also repairs and replaces parts and components for air defense units; repair the hydraulic system that controls the rotation of the radar antenna on the ship; manufacturing and mechanical processing of components for the X51 Factory and the General Department of Defense Industry. To meet the requirements and tasks of aeronautical engineering repair, the factory has promoted the spirit of self-reliance, self-reliance, collective intelligence, designed hundreds of mechanical drawings for processing and manufacturing. components, spare parts, technical materials for repair and production. Not only that, but the factory also compiled many documents, including bilingual documents, especially the set of major repair technology, increasing the service life of Su-22 and Su-27 aircraft. Vietnam’s success has surprised the Russian side, in a recent article titled “Su 27/30: Vietnam will repair itself at home”, Russian defense magazine VPK said that Vietnam has self- Repairing and upgrading Su-27 and Su-30 fighters at the new factory in Da Nang. Accordingly, Vietnam is building capacity for basic maintenance and repair of Su-27 and Su-30 fighters, to avoid sending aircraft abroad. To implement this program, Vietnam recently put into operation the A32 defense plant in Da Nang. “The self-repair and upgrade of the aircraft in the country will significantly increase the operational readiness of the fighter,” the source confirmed. According to VPK, to get this result, A32 Factory sent dozens of staff to train abroad. Currently, the factory has successfully repaired the failures of this modern fighter on its own. Each workshop repairs a technical array with over 10,000 different components that require extreme caution, precision, and meticulousness.

According to relevant information, the “KF-16” fighter jet was developed by the “Korea Aerospace Industry” (KAI) in the 1990s. The reference prototype developed by the aircraft was designed in accordance with the “F-16C” fighter aircraft authorized and licensed by the US government. Although the South Korean Air Force has previously stated that the country’s KF-16 fighter jets are not “simple assembly” of American F16C fighter jets. However, the Korean fighter is almost the same as the American fighter in terms of appearance and internal core parts.

Regarding this accident, after some foreign media forwarded it to the national social platform, it caused a lot of heated discussion. In addition to Japanese netizens who ridiculed South Korea’s “backwardness” in maintaining military power, many Internet users in other countries ridiculed the arrogance of South Korean netizens who boasted that “Korea’s military is one of the best”.

One netizen’s comment left us very impressed: “Low EQ: the quality of the aircraft is not good, high EQ: the ejection device is reliable.” After that, he added: “For Korean directors, they like to “touch the scene and give birth to love”, exposing the domestic darkness and shooting. The habit of high-quality movies, I now even think about the name for them, let’s call it “Emergency Catapult”! Then make an earth-shattering realist movie that criticizes the South Korean government! Hahaha.”

In addition to the ridicule of foreign netizens against the South Korean army, South Korea’s “good father”, the Americans, had an indescribable “contradictory sense” after seeing the accident. In order to avoid the problem that netizens in other countries think this is an “American fighter jet”, an American netizen commented: “It is all due to the poor development of the Korean military industry. If this aircraft is originally imported from the United States by South Korea, it will certainly not be the case. The problem occurred only because South Korea assembled this aircraft!”

However, this American brother may not know the fact that most of the core designs and parts of the KF-16 fighter in the accident came from the United States. In fact, not only the KF-16 fighter jet that has been involved in the accident, but also the K1 and K2 main battle tanks, K9 self-propelled artillery, etc., South Koreans are proud of. Many of them rely on the core technology of the United States or Western European countries to become theoretical. Excellent military vehicle.

And these vehicles are basically at the world’s advanced (sub-top) level in terms of paper data. But what is interesting is that the South Korean military does not have so much military foundation and practice and technology in front of these excellent works. For example, before Japan’s Type 10 main battle tank matured, there were continuous development and improvement of Type 90, Type 74 and other main battle tanks. The Leopard 2A7 main battle tank in Germany also has Leopard 2A4, Leopard 1A5, Leopard 1 prototypes and other main battle tanks with a lot of technical and actual support to make the German main battle tank a contemporary classic.

Compared with these veteran military-industrial powerhouses, South Korea lacks a foundation. It depends on finding the authorization and then assembling advanced equipment such as combat systems, drive systems, suspension systems, and sighting equipment purchased from European and American countries. After that, in combination with South Korea’s national conditions, we will continue to imitate and experiment to produce military vehicles that can be “closed” to the global advanced level.

The most important thing is that the military vehicles they developed are more “good quality and cheaper” than the advanced military vehicles exported from China, the United States, Russia and Germany in terms of external sales prices (of course, not all Korean-made vehicles are very cheap) . However, the price is the “Made in All Nations System”, and the later stability is worrying, and maintenance is more troublesome. In short, although there will always be weird conditions during service, based on paper data, the military vehicles produced by South Korean military industry do have a certain combat effectiveness. .

In fact, for a small country like South Korea that has poor top military technology but wants to “autonomize the military industry”, it is more suitable for them to take the path of “exporting” by assembling the Wanguo brand and experimenting with self-research. But if this set of thinking is applied to the country’s long-term military development, it will undoubtedly make South Korean logistics maintenance personnel, especially the maintenance personnel of high-precision vehicles (fighters and warships) hurriedly, once serious problems occur, they will have to review and repair all. . For example, the accident of the KF-16 fighter jet is a typical case.

Born with the blood of a magical creature (Frost Giant) and trained by Frigga himself, Loki is truly a talented magician. Although he proved to be inferior to subjects like Doctor Strange or Scarlet Witch, his skills were still good enough to impress mighty men like Odin. He himself had admitted that if Frigga were alive, she would be proud of him. So what kind of magic does Loki possess? Create Illusion Loki can create multiple illusions of himself at once, aiming to throw enemies into chaos. This skill was so perfect that he didn’t need to say a spell or do any movement to perform it. However, because they are only illusions, they cannot affect the environment. When someone tries to interact with the illusion, they will pass through it and will emit green light around wherever it is touched. In return, each of these illusions is so real that Loki can fake his own death, or physical condition in front of others. They can also be used to “communicate” with a remote object, even if the owner is standing in a different location. Concealing Presence Loki can make himself invisible to others, and not to hear anything he says. Basically, this is not really “stealth”, but a move that affects the mind of the target. Even Heimdall’s superior senses of the universe’s number one couldn’t detect Loki’s whereabouts while he was in Jotunheim. In addition, Loki can also apply this spell to many other objects. Thanks to that, he was able to easily send the Frost Giants into Asgard. Psychic Loki can influence the mind of the target to a certain extent. With this move, he can control anyone’s mind and force them to follow his orders unconsciously. The spell is so powerful that it can affect Odin, leaving him in Midgard while Loki usurps his throne as king of Asgard for four years. However, this spell does not last forever and Odin was able to break it before Ragnarok took place. In addition, this ability also allows Loki to read the subject’s memories, and the affected subject must also “experience” that memory. Transfiguration Transfiguration is one of Loki’s forte. Transformation spells can be cast on the entire body or parts (of the owner and others), allowing Loki to change his clothes, voice, and appearance to resemble a human or other animal. . Loki’s transformation is so proficient that from an early age, he was able to transform himself into a snake to trick Thor, with a disguise convincing enough for Thor to pick up and hold without a doubt. which. Of course, this spell is also powerful enough for Loki to create objects like daggers and other equipment. It can be said that this is magic without limits. Thanks to it, Loki was able to disguise himself as Odin for a long time without being detected by any of the Asgardians. Summon This spell allows Loki to summon any object from nowhere, such as summoning Han Dong Bao He, and then returning it to its original position when it is no longer needed. This can be said to be quite a convenient spell, as Loki can take whatever he needs without having to bring it with him. Telekinesis Loki can act on objects and move them with just his will, similar to creating an enormous shock force. During the skirmish between Loki, Thor, Sif, the Three Warriors, and the Frost Giants, Loki used his telekinesis to amplify the damage of each knife he threw from a distance. Upon hearing the news of Frigga’s death, Loki in a fit of rage clenched his fists and blew everything around the cell against the wall, creating an impact that caused the cell to shake violently and generate electromagnetic pulses in it.

The Defense World page said that with this upgrade package alone, the F-15SEs are enough to make the latest version of the Su-30SM1 inferior and slightly better than Russia’s most powerful 4++ generation fighter today. Su-35. American F-15 fighter. According to this source, the Su-30SM1 variant has been focused on modernizing the avionics system as well as adding modern weapons to help it have the same combat power as the Su-35S. So how is the strength of the Su-30SM1 when compared to an opponent from across the ocean that is the US-made F-15SE because both are in the line of heavyweight air superiority fighters with 2 seats. ? The US newspaper puts the situation that once a direct confrontation occurs between these two fighters, will the bigger victory belong to the Russian fighter or the American fighter? First, the strength of these two heavy fighters and always decisive is long-range air combat. While the Su-30SM1 almost retains the hardware components such as the passive phased array radar BARS N001M, with only software upgrades and a faster processor, on the F-15SE is the AN/APG-82 radar belonging to the F-15SE. Active scanning mode (AESA) has greater accuracy, long range and reliability. The biggest advantage of active phased array radar is its ability to jump frequencies very quickly in a very short time, making it impossible for the enemy to take appropriate electronic countermeasures. The radar reflection area of ​​the F-15SE is very small because it is covered with stealth paint and puts all the weapons in the compartment, making it close to the 5th generation fighter. As for the Su-30SM, it has no improvement. No progress in this area, the RCS is too large with the addition of a pair of nose wings, making it possible for it to be detected in advance by the F-15SE from a great distance and launched a missile to destroy. The Su-30SM1 uses an AL-31FN turbojet engine with a thrust of 12,500 kgs each, while the Silent Eagle is two F110 engines providing a thrust of 13,150 kgs. The maximum speed of the Russian fighter is Mach 2, while in the F-15SE this figure is Mach 2.5+. Russian fighters still can only carry 8 tons of weapons, much inferior to the F-15SE, if taking advantage of the external mount, the maximum capacity of the US fighter is up to 10.4 tons. Part of the above advantage lies in the higher durability of the US fighter’s fuselage, which is also reflected in the F-15’s critical flight hours of 8,000 hours, while the Su-30 is still only 3,000 hours. The only way that can make the Su-30SM1 gain an advantage over the F-15SE is to pull it into a short-range air battle, at which point the 2-way thrust vector control engine and the nose help the Su-30SM1 take the position. better mind. But Russia also needs to watch out for short-range air-to-air missiles with a “lock on target after launch” mode of US fighters because this weapon will make the advantage of mobility disappear.

Two US F-35 fighter jets attempted to enter Syrian airspace and approach a Russian military base in the Syrian Arab Republic. However, Russian air defense systems at Khmeimim airbase and Russian naval base in Tartus (Syria) detected it. The US F-35 was confident in its superior stealth capabilities, but it was quickly discovered by Russia. Immediately after being exposed, a Russian Su-30SM was dispatched to intercept. The Su-30SM has just had an F-35 interception that scared US pilots. According to information obtained by the AVP news agency, the Russian fighter jet hid by activating electronic countermeasures and approached two US F-35s without being detected. The appearance of the Su-30SM was completely unexpected for American pilots. Despite the overwhelming advantage in numbers, two F-35 fighters were forced to turn around immediately and leave the border area of ​​Syria. “The F-35 pilots panicked and realized their failure. They don’t think long and want to leave the danger zone,” reads a document published in the Baijiahao publication. Up to this point, this is the second incident involving the Russian Su-30 fighter intercepting the US F-35. Russian patrol cars stopped American armored vehicles a few days ago. In recent times, Russia and the United States have frequently encountered each other in Syria. In each of the US violations, Russia reacts very strongly, thereby sending a clear message to Washington. A few days ago, two US and Russian patrol convoys had a tense clash. The voluntary movement of US forces was stopped by the Russian military police and this is also the second time in about 30 days that the two sides’ forces have clashed on a Syrian highway. The unannounced move is seen as an act of US tension in relations with Russia in Syria. With its fierceness, Russia also had a response message. Recently, a published photo shows Russian patrols approaching a US military facility in the east of the Syrian Arab Republic. The published image shows that Russia’s “Steel Leopard” BTR-82A aimed guns at the US command post and armored vehicles. According to the AVP news agency, this close action proves Russia’s superiority and it is also a way to convey the message “all provocations will be quelled”. The photo shows that the US base and armored vehicles are within range of the “Steel Leopard” BTR-82A. In the photo published on the Telegram community, we can clearly see that the BTR-82A armored vehicle’s gun is aimed directly at the US military base. To this day, it is not clear where and under what circumstances this photo was taken. But, before this photo was published, the Russian military convoy stopped the American convoy. “Iron leopard” BTR-82A terrified many enemies on the battlefield. (ARMIES POWER source) It should also be noted that since the beginning of the year, Russia has significantly increased its presence in the territories of Syria. And from Washington’s perspective, some of the areas where Russian forces have increased their presence are already controlled by US forces. AVP source said that Russian military equipment and even military aircraft have appeared more and more often in these areas. Peace (According to AVP)

While the news of their budding romance may come as a surprise to some, the two stars had a relationship in the fashion industry nearly a decade ago. The star couple’s information surfaced at the end of May. DeuxMoi page said: “Kanye is secretly dating Irina”. Photo: Nativenewspost. In 2010, Irina Shayk rose to prominence but made a cameo appearance in the MV Power by Kanye West. Soon after, she was chosen to participate in his fall 2012 show at Paris Fashion Week. Irina Shayk strutted down the catwalk, wearing a tight velvet evening gown, lace-up gladiator boots, a black leather jacket and dramatic smoky eye makeup. Incidentally, Kim Kardashian – who at the time had just started dating Kanye West – wore his designs and sat in the front row of the show.

Pop Sugar at that time. “I consider Kanye West to be one of those rare people who bring new ideas to the world. He brought art into his music and unleashed his passion for fashion. This is not found in many musicians. He has a very good eye for fashion and is not afraid to try new things,” the supermodel said. After this, Irina Shayk continued to support Kanye West’s fashion endeavors. She wore his t-shirt design when she became the focus of her walk on the street. According to the Pagesix , the supermodel honored DMX in late April by giving away a $200 Balenciaga x Yeezy T-shirt. The design helped raise $1 million for the late rapper’s family. Irina Shayk pays homage to DMX in a design collaboration between Yeezy by Kanye West and Balenciaga. Photo: The Sun. Irina Shayk and Kanye West also happen to be close friends with designer Riccardo Tisci – who served as creative director of Givenchy for 12 years before taking the helm at Burberry in 2018. Shayk has starred in campaigns and appeared on the runway for designer Tisci during his time with both fashion houses. Meanwhile, Kanye West invited Tisci to create the cover art for the 2011 album with Jay-Z, as well as for Cruel Summer year 2012. Then Kanye West introduced Tisci to Kim Kardashian. The Givenchy head has designed many styles for shaping and beautifying outfits, including the famous floral gown and gloves she wore at Met Gala first with Kanye West in 2013. Riccardo Tisci is rumored to have inspired Kanye West’s breakthrough in fashion. Coincidentally, he also sat in the front row at the show where Irina Shayk appeared in the fall 2012 show.

“However, it is still too early to announce the modernization of the Su-57”, said Major General Vladimir Popov, member of the Expert Council of the movement “Strong Russia”, Honored Military Pilot. launched and added, so far only 3 squadrons are flying this new generation fighter. “Here, we are most likely talking about the completion of the second-stage engines. By the end of the year they are expected to enter series production with characteristics that are true to the standards of the 5th generation aircraft.” “Today, the Su-57 flies on the AL-41F1S for 4+ generation fighters, despite its high maneuverability thanks to thrust vector control, a new engine has been produced for it, went through testing and the certification was practically passed,” Popov said in an interview with PolitExpert. The upgraded version of the Su-57 is most likely just a second-stage engine integration Now the central question regarding when to put the new engine into production is decided. Boris Popov suggests that Minister Manturov is most likely alluding to this when talking about the modernization of the Su-57. Phase two engines have been included in the project, but their creation is being delayed. “It has to do with economic issues at home and abroad, especially when Western rivals have come a long way. But now this period is over. We are completely independent. production, testing new engines and getting ready for mass production,” Major General Popov explained. “Currently in practice, operational experience is being gathered when the characteristics of the aircraft are confirmed,” emphasized Popov. “It’s not the test engineers that prepare the aircraft, but the technical staff who work directly in the unit. This is like another human quality. In this case, some nuances emerge, those New processes are being approved, parts or even systems are changing,” said the honorary pilot. “Two years have passed since these aircraft entered service with Air Force units. There have been a number of minor changes that need to be made to the structure. This is also a type of modernization for the Air Force. for the Su-57”, Major General Vladimir Popov concluded.

“As early as Soviet times, this concept was formed when our armed forces simultaneously used front-line fighters of both heavy and light.” “If in the fourth generation, the MiG-29 plays the role of a twin-engine light fighter and the corresponding heavy is the Su-27, in the fifth generation we have the same twin-engine Su-57. for expensive”. “Until recently we did not have an aircraft of another light weight class,” said AviaPort’s head of analysis, expert Oleg Panteleev. At the same time, light and heavy fighters are designed to solve different problems. “Heavy fighters are needed to cover large areas, which means they have to fly a long enough distance before completing the mission,” the expert explained. “For light fighters, aircraft with fuel reserves and a smaller combat range, another mission has been determined. Figuratively speaking, it would fight over a protected object and tackle an equivalent range of missions in terms of versatility, including aerial combat and assault against ground and water targets, but at a shorter distance from its base,” added Panteleev. Concept graphics of a new generation of Russian single-engine light fighter This expert considers the idea of ​​​​building a single-engine fighter to be right. “Common sense, a single-engine aircraft will always be cheaper than a two-engine aircraft if we consider comparable performance,” he said. “However, in the event of one engine failure, the plane is likely to crash, while a twin-engine aircraft can continue to fly thanks to the other engine.” “But with the progress being made in improving the engines and increasing their reliability, situations where engine failure leads to the loss of an aircraft are quite rare. Second, rescue work has developed well enough to ensure guarantee the rescue of the pilot,” Panteleev said. The expert also pointed out that at the test stage, Al-31FN series 3 and 4 engines can be used. In addition, during aircraft construction, flight tests can be performed on existing engines to check the operation of systems independent of the dynamometer. Of course it does not match the full range of engine characteristics that are the target of the aircraft. “We also know that the AL-31 and its modifications are a well-run and mass-produced engine with high reliability due to the modernization carried out. So at the experimental stage, its use proved to be quite reasonable,” said Panteleev. At the same time, the expert noted that the construction of engines that can be used in the light version of the fifth-generation aircraft has been taking place in Russia for a long time. “We remember that the new engine for the Su-57 was used and the T-50 prototype of the Su-57 fighter even flew with this engine. So there will certainly be no delay in creating a new engine,” Panteleev said. As for the difficulties that need to be solved when building a fifth-generation light fighter, the expert notes a large number of requirements for it. Often these requirements conflict – “compact, low reflectivity and high payload, long flight time and, if possible, supersonic cruise; deployment of concealed weapons and an increase in the range of weapons carried, including relatively large long-range missiles”. “So the main difficulty is how to achieve the optimal combination of requirements, and at the same time to compete on price so that the aircraft does not burden the Russian budget and is attractive for export.” Mr. Panteleev concluded.

The unique design enables the Su-17/22 to fly at low altitudes at high speed or at high altitudes at supersonic speeds. Weapons are quite diverse and for a long time it is always the nightmare of any ground force confronting them. Su-17/22″ fighter Su-22M4 is the last production variant of this swing-wing fighter with significant upgrades to the avionics including: RSDN navigation system, inertial navigation system, range measurement system. laser way, radar warning system SPO-15LE, in addition on the aircraft design additional air intake slots to have more airflow to cool the engine. Su-22M4 – the most powerful variant of this fighter line After the dissolution of the Soviet Union, Russia inherited a lot of this fighter, this is also the only single-engine supersonic fighter that Russia owns, they continue to serve effectively in the frontline air force. and it was not until 1996 that they were completely scrapped to be replaced by more modern fighter lines.

Orders for the F-16 fighter version Block 70/72 will be completed at the factory in Greenville. Nearly 400 jobs will be created to support this production line, almost double the workforce employed at Lockheed Martin’s plant in Greenville. This will be the only surviving F-16 production line in the world. It was set up three years after Lockheed Martin discontinued the line in Fort Worth, Texas. Recently, representing five partner countries, the US Air Force signed a contract with Lockheed Martin worth $14 billion to build 128 F-16s by 2026. The first F-16s of this line will ship in 2022 and production will increase steadily in the following years. These aircraft will be delivered to Bahrain, Slovakia, Bulgaria and Taiwan territories. The F-16 Block 70/72 will be integrated with active electronically scanned array radar (AESA), advanced medium-range air-to-air missile (AMRAAM) with longer strike capability, and a suitable expanded fuel tank. with the fuselage. Even after 2026, the US is expected to receive more orders for the F-16 due to its reasonable price and versatility.

Since 2015, Russian engineers have sought to increase the combat capabilities of the Su-30SM. In particular, the plan to combine Su-30SM with Su-35S is also very feasible. To carry out this plan, engineers prepared a new Su-30SM model with a new engine, and studied the possibility of installing a new, more powerful “Irbis” radar instead of the current system. During the modernization process, the developers will propose to install the AL-41F-1C engine using the Su-35 for the Su-30SM2 version. The new engine is much more efficient than the current Su-30SM. “The life cycle of aircraft engines has doubled without increasing weight and size. Equipped with a plasma ignition system, the AL-41F-1C engine is more economical than the AL-31FP engine that the Su-30SM is using. With the same amount of fuel, the upgraded fighter can stay in the sky longer. In addition, the avionics, radar and visual positioning system have also been improved,” said Cadim Kozulin, an expert at the Russian Academy of Military Sciences. With the engine power and possibly the radar will also be upgraded, the Su-30SM2 Super Sukhoi will be a formidable opponent of the latest US F-15EX.

F-35A Lightning II . (Source: airforcemag.com) According to Sputnik, Air Force Magazine considers the F-35A Lightning II to be the most effective fighter aircraft in the world US Air Force . The magazine notes that between 2019 and 2020, the Mission Capable Rate (MCR) of this fifth-generation fighter has increased from 61.6 to 76.07%. Meanwhile, this parameter of the F-22A Raptor has increased from 50.57 to 51.98%; The MCR of the F-15C, F-16C and F-16D increased, but decreased with the F-15D and F-15E. The improved combat capabilities of the F-35A Lightning II are due to the renewed fleet of aircraft, as well as an increase in the number of available spare parts and the opening of new warehouses for them. The magazine reiterated that the US Air Force plans to phase out the F-15C and F-15D, as well as in the future to phase out the F-15C. F-22A Raptor . Earlier in April, The Drive reported that the US Air Force’s F-35A Lightning II would be equipped with a tablet with an “app store.” However, Defense News revealed F-35A Lightning II incapable of traversing significant distances over the Pacific Ocean in air-to-air conditions aerial refueling ./.

In the current payroll of the Russian Aerospace Forces, there are more than 2000 jet aircraft of all types. However, this force only uses two-engine fighters, does not own any single-engine fighters. One of the main reasons is that most of the fighters in the current Russian Aerospace Forces, most of which are fighters developed from the previous Su-27 series, use two jet engine. However, part of the reason why Russia did not use single-engine fighters in service, came from the lack of it in the final stage when the Soviet Union was about to disintegrate. Specifically with the MiG-29 fighter. This type of fighter, when developed, was aimed at a single-engine fighter design, to compete with the US-made F-16 fighter. However, this design encountered a very difficult obstacle, that is, the Soviet Union at that time did not have a jet engine strong and light enough to be applied to the design of the MiG-29 at that time. . Designer Mikoyan then had to revise the drawings of the MiG-29, forcing it to use two jet engines instead of one as originally envisioned. Basically, at the last stage when the Soviet Union was about to disintegrate, it was very difficult to spend money on research and manufacturing of new generation jet engines. The fighter designers were then forced to use all that was available to them, and the idea of ​​a single-engined Moscow fighter jet ended since. However, it can still be considered that twin-engine fighters have more advantages than single-engine fighters. The US itself at the present time has also stopped producing single-engine fighter aircraft, the F-16 version, although very popular, has only received further upgrades so far, the new production line has been closed. Doors from 2017 to 2019 are allowed to reopen, but only for export. Compared with single-engine fighters, dual-engine combat is considered to be more stable in operation. In the event of one engine failure, at least one remaining engine is enough to bring the plane to a safe landing. Two engines, which means that the aircraft will have two independent power supplies to power the computer system, and also the hydraulic systems on the plane. With single-engine fighters, once the engine stops working, the aircraft will immediately fall into a state of loss of control. Especially with today’s modern aircraft, which use fly-by-wire electronic steering, as soon as the engine is turned off, the computer will also turn off and the steering system will be useless immediately. The American F-16 fighter itself also uses special fuel, along with an electrical energy storage system, allowing the aircraft to operate for an additional 10 minutes after the engine is turned off. At the end of 10 minutes, the energy reserves will run out and the aircraft will also be uncontrollable. In the opposite direction, a single-engine fighter has the advantage of being more compact, lighter, and more fuel-efficient when compared to a twin-engine fighter with the same output thrust. Even the US F-16 fighters, capable of carrying weapons up to 7.7 tons, are only 300 kg inferior to the Russian twin-engine Su-30 aircraft. In the future, Russia is looking to replace its MiG-29 fighters with a single-engine fighter. However, up to now, the design of the new Russian single-engine fighter is likely still on paper. The first thing Moscow needed was a jet engine powerful enough to carry the fighter. Image source: Pinterest. Russia’s MiG-29 fighter is still considered the most “light” fighter that Moscow owns.

The Eurasian Times has just published a graphic image of a single-engine fighter, believed to be of a future design, built by Russia based on the Su-57 fighter, in order to overcome the biggest weakness of this aircraft. , which is the lack of stealth. Accordingly, Sukhoi Corporation has embarked on the design of a new fighter, based on the original design of the Su-57, but enhancing stealth to a new level. Information from the Eurasian Times also said that it is likely that the next design of this new fighter jet will be equipped with only one engine. So far, the Russian Su-57 fighter has always been praised for its excellent maneuverability and speed, but to achieve speed and maneuverability, the Su-57 at the expense of invisibility. Although Russia has never acknowledged it, many military experts believe that the 3D vector engine design on the Su-57 is the fighter’s fatal weakness in front of enemy radars. Unlike the engine design hidden inside the stealth cover of the aircraft like the US F-22 Raptor, the engine of the Su-57 fighter is almost completely exposed. The radar-absorbing shell of the Su-57 fighter does not cover the aircraft’s engine parts, which means that, even though the entire Su-57 is invisible, its engine will still be targeted by enemy radars. side caught. The difficulty of Russia is that the engine of the Su-57 has too good performance, generates a lot of heat and is a 3D vector engine. All of these factors will make the Su-57’s engine impossible to fit inside the aircraft, nor can it be covered with a radar-absorbing shell on the outer surface. The US itself has admitted to trading the maneuverability, as well as the speed of the F-22 Raptor and F-35 fighters in exchange for superior stealth, but with the Su-57 everything is different. does not appear to be going in this direction. In addition, information about Russia’s next 5th generation fighter model will be equipped with an engine, also making many people curious and excited. Since the dissolution of the Soviet Union, Russia has not built any single-engine light fighter. Russia’s lightest fighter today, probably the MiG-29 – is also equipped with two engines, and can be considered a medium fighter. The single-engine fighter, in theory, is not much inferior to the twin-engine fighter in terms of weapon carrying capacity and aerial range. Not to mention, single-engine fighters will have lower production costs, shorter assembly times, and lower usage and depreciation costs. Currently, on the world market, the US F-16 single-engine fighter is still “hegemonic” and has almost no rival. Despite having only one engine, the US F-16 fighter is still capable of carrying up to 7.7 tons of weapons – only 300 kg less than the maximum weapon load of the Su-30. This is currently also the backbone of the US, with 1,300 in service, the most numerous fighter in the world at the moment. The test pilot pushed the Su-57 fighter to the limit of its maneuverability with a series of unbelievable flight maneuvers. Source: Sukoi.

Sukhoi’s Su-57 fighter Associated TASS May 26, citing a source in the Russian military aircraft industry, said the above information Sukhoi is a well-known company in the military aircraft manufacturing industry, especially the Su-family fighters and fighters such as Su-27, Su-30, Su-35 and the latest is the Su-57 stealth fighter. . These aircraft are all 2-engine, similar to the MiG family fighters in the Russian air force such as MiG-29, MiG-35… Source of TASS “The Sukhoi company is developing the first single-engine light tactical aircraft in modern Russian history with a take-off weight of up to 18 tons,” said the statement. According to him, the aircraft can reach a maximum flight speed of more than Mach 2. The fighter is distinguished by its super-maneuverability and improved take-off and landing characteristics due to the impact of the propulsion engine. push vector. In early April, it was reported that the Russian Ministry of Defense had approved the final exterior design of a new type of stealth bomber, also known as the “advanced long-range aviation complex” (PAK DA). ). The PAK DA aircraft is being developed by the Tupolev company with the priority of reducing radar reflections and equipping long-range weapons. Sheet Izvestia news: Several features of the PAK DA have been approved after a series of tests to determine the level of radar signal reflection, aerodynamic test results. “Work on the development of the PAK DA program is at the detailed design stage, construction of several prototypes of a promising bomber is underway,” RIA Novosti quoted a source in the Russian military-industrial complex as saying. The source said that the new bomber will be built according to the “flying wing” aerodynamic scheme, with subsonic speed and long flight time. In addition, it will only use internal weapons, including hypersonic missiles. “It is said that this bomber will be able to control groups of unmanned aerial vehicles and therefore be able to use almost any type of air-to-air missile,” the source said. The new bomber is expected to enter service in 2027. It is expected to replace the Tu-95MS turboprop bombers in the Russian Aerospace Forces. Earlier, it was reported that the Russian Defense Ministry was working on a project to build a special unmanned aerial vehicle (UAV) and a control system for it to be able to engage in anti-submarine warfare. Potential platforms for creating such an apparatus are currently being studied, sources in the Russian Defense Ministry told. Izvestia . In the future, there are plans to use heavy drones equipped with anti-submarine weapons. Several devices combine to form a network that can coordinate the search for the enemy. The drones can be launched from airports or from land. They will be controlled from both aboard and in the air, aided by automation capabilities and artificial intelligence elements. These devices can attack the target independently or in combination with the weapons of other anti-submarine weapons.

55ZH6M Nebo-M radar station of the Russian military. Photo: Russian Ministry of Defense Yan Noviko, General Director of Almaz-Antey, said at a forum on new technology in Moscow on May 23: “The Nebo-M radar system is the ‘killer’ of stealth technology. Radar can detect F-22, F-35 relatively easily. Mr. Niviko also said that Almaz-Antey is capable of producing about 30 types of mobile multi-purpose radar, thanks to proper investment in research projects as well as new technology. 55ZH6M Nebo-M is the latest Russian radar, designed and manufactured by the Nizhny Novgorod Radio Engineering Research Institute (NNIIRT) of Almaz-Antey. Along with the Container radar, the Nebo-M surveillance station is considered the backbone of the battlefield radar network on Russia’s land borders. So far, 55ZH6M Nebo-M has been deployed in all the most important directions in Russia. The first Nebo-M complex was delivered to the Western Military District in 2017, followed by combat units stationed in Transbaikalia, Khabarovsk and Primorye. A year later, this advanced radar network was deployed in an air defense unit based in Crimea. The portable Nebo-M system can be rapidly redeployed to other locations by land or air. The new Nebo-M series is capable of detecting aircraft and ballistic missiles at a distance of up to 1,000 km, a big step up from the early Nebo radar systems developed under the Soviet Union. This radar station operates on the principle of active electronic scanning, making the 55ZH6M Nebo-M capable of resisting enemy jamming. When specifically installed to track targets at medium altitudes, Nebo-M radios are sometimes equipped with low-altitude radar systems like the Podlet-E. Is it really something to worry about with US stealth fighters? TASS news agency (Russia) quoted Noviko as saying that stealth technology does not cause difficulties for Russia’s new radar complexes. In theory, this is true, because VHF high-frequency radars like the 55ZH6M Nebo-M can identify an F-35 or F-22 in flight. American stealth fighter F-35. Photo: Reuters American experts say that there are many things to confirm in the Russian statement. Identifying a new target is the first step and part of the process of catching and killing the target with many stages. After locating the target, for example the F-35, the requirement for the radar station is to fix the target, track, and “catch” successfully before transferring the parameters to the unit tasked with destroying the target. target. According to General Dan Flattley, a former F-35 pilot of the US Air Force, in order to destroy the F-35, Russia must build a chain of target destruction. This task is usually performed by Russian anti-aircraft missiles, such as the Russian S-400 defense system. Until now, whether the S-400 is capable of destroying the F-35 or F-22 stealth fighters is still a subject of debate. Technically, it is clear that the 55ZH6M Nebo-M watchdog can identify the US 5th generation fighter. But that’s only part of the battle sequence. Locating is one thing, but whether Russian air defense systems can destroy the F-35 and F-22 is another story, because many factors are involved. If “detect” but not have the ability to “precise attack”, the radar’s performance does not make much sense. US stealth technology only needs to overcome the “destroy” limit of Russian missiles to be considered successful.

First clear image of a working J-10C with WS-10 engines/ Source: Chinese social media As with so much in China’s air force, much of the J-10’s history is shrouded in mystery. It is understood that the J-10 fighter originated in the 1980s, the prototype was the J-9, a delta wing fighter that was abandoned in the 1980s. It is also believed that the J-10 enjoyed benefit from Israel’s Lavi fighter program. The J-10 fighter was considered a state secret until January 2007, when the media revealed that it had entered service with the PLAAF. A few months later, in May 2007, the Russian arms agency Rosoboronexport announced a $300 million deal to sell 100 Saturn AL-31 engines to China’s J-10 fleet. Then, at the end of 2008, the J-10A made its public debut at the Airshow China exhibition in Zhuhai. Since that time, the AL-31 has been the key engine for all variants of the J-10, from the original J-10A to the more advanced J-10C. Challenges related to the development of the domestic Shenyang WS-10 Taihang engine forced the J-10 to stick with the Russian engine longer than planned. Finally, in early May, a J-10C in a combat unit equipped with a WS-10 engine was discovered by the public. However, there is no official statement yet. Instead, a clear photo of a flying J-10C with a WS-10 engine appeared on social media. Andreas Rupprecht, author of China’s Modern Fighter, was one of the first observers to comment on this. “This is a real milestone not only for the J-10, but even more so for the WS-10 program as it marks the end of China’s dependence on the Russian AL-31 engine for the AL-31. with all three of the PLAAF’s main fighters, namely the J-10C, J-16 and J-20,” he said. He noted that a decade has passed since the J-10B first flew with the WS-10 and that the engine was tested on the J-10A even earlier. Finally, after years of improvement, it seems the WS-10 is reliable and safe enough to power a single-engine fighter. Mounted inside the J-10, the WS-10 can be identified by several characteristics. One is that the petals of the posterior burner are significantly wider than those of the AL-31. The WS-10 also has a structural ring inside the nozzle that is not present on the AL-31. The J-10A used by the Chinese aerobatic team can be distinguished from later variants by its rectangular intake that is not horizontal to the fuselage. This variant was in production until the end of 2014, when production switched to the J-10B. However, the J-10A has been modernized, including the ability to carry the PL-10 infrared-guided missile. However, to evaluate the success of the WS-10 engine requires one thing: Time. Only through use can we know if they are really good, really replacing the Russian AL-31 engines.

The MiG-35 is an upgraded product of the MiG-29K/KUB and MiG-29M/M2, which is currently undergoing final testing. “The MiG-35 is in the state-level general testing stage and has already obtained preliminary certification to obtain the certification,” said Musheg Baloyan, Director of the MiG-29M and MiG-35 Aircraft Program at the MiG Aircraft Corporation. can be put into pilot production. Pilots love these planes because they are easy to operate and offer many advantages.” MiG-35 . fighter The MiG-35 is the 4++ generation of aircraft. They are equipped with a series of modern technology, but the fate is extremely bleak. Since its announcement in 2007, the development of the MiG-35 has been relatively slow. Only in 2013, the Russian Air Force announced plans to buy a total of 37 of these aircraft. Up to now, a total of 14 MiG-35s have been produced, of which 6 are in the process of testing and 8 are in the mass standard. Russia remains the sole operator and operator of the MiG-35. MiG-35 . fighter The Russian media must also admit that, although there have been many changes, it is the appearance that is almost unchanged compared to the MiG-29 that makes them lose their attractiveness, besides, despite having an engine with a thrust direction. multi-dimensional, but this RD-33MK engine is really just an improvement from the RD-33 that was born in the early 1970s. On the other hand, the RD-33 was never considered an excellent engine, They are quite fuel efficient and often emit black smoke trails. Previously, even the Russian Ministry of Defense also refused to order this fighter line, many sources also said that Russia was forced to buy MiG-35 to leverage the promotion and export of this aircraft. and most importantly, to save the plane maker Mikoyan from bankruptcy. Perhaps Mikoyan has to do more for the MiG-35 – because this is their only salvation at the moment – for this aircraft to become a ‘hot’ item similar to the Su-35, first of all. is the trust of the Russian air force itself, then the air forces of countries that have traditionally used Russian aircraft.

The US Air Force recently conducted a test for the F-15E multi-role fighter when it carried five long-range air-to-surface missiles to attack outside the AGM-158 JASSM air defense point. These 1-ton stealth missiles will give the Strike Eagle the ability to hit land and sea targets equivalent to a bomber, while the air combat capability remains the same. To mount the AGM-158 JASSM to the F-15E’s external fuel tank mount requires a specially designed mechanism. At the same time, the aircraft still carries 2 short-range air-to-air missiles and 2 medium-range missiles, a total of 9 missiles. Despite being born for a long time, the power of the “Attack Eagle” F-15E is said to be still superior to many opponents in the world, now with a large number of AGM-158 JASSM missiles, Strike Eagle has become more and more multiple. dangerous part. AGM-158 JASSM is an upgrade from AGM-154 JSOW, officially put into service with the US Army in the mid-1990s, this is essentially a stealthy cruise missile equipped with a jet engine with Super long range, enough to overcome all the most advanced air defense systems. The AGM-158 JASSM missile is equipped with a Teledyne CAE J402 jet engine that allows to operate over a large area for a longer time. The missile’s body is designed with stealth capabilities and infrared shielding measures that make it very difficult to detect from a distance by radar systems. The AGM-158 is equipped with a very sophisticated navigation system that combines updated INS inertial guidance from the GPS global positioning system with an infrared sensor for finding and locking the target at the end. . The missile is also equipped with a data link that updates the operational status during the flight to change the target at the last moment if necessary. Significant improvements in the engine and aerodynamics give the AGM-158 JASSM a range of up to 370 km and up to 1,000 km in the JASSM-ER variant. The AGM-158 JASSM operates as an air-launched ground-attack cruise missile, not a clever glide bomb like the AGM-154. The range of the AGM-158 missile has exceeded the reach of most modern air defense systems today, helping the aircraft carrying it not have to enter the danger zone. Stealth capabilities and a new generation of quieter jet engines, which can operate at low altitudes below the range of radars, allow the missile to launch a surprise attack that makes the enemy unable to react. The AGM-158 JASSM has a variant of the AGM-158C LRASM super-long-range anti-ship cruise missile, which will be the main attack weapon of the US Navy fleet in the not too distant future. With the AGM-158 family of attack missiles, the US Army wants to convey the message that speed is not the core factor that gives a weapon’s power, this direction of theirs is completely different from that of Russia.

“India Today” reported on April 21 that India is using the airborne oxygen generation technology on the self-produced light fighter “Glory” to alleviate the severe oxygen shortage caused by the new crown epidemic.

Indian Defense Minister Rajnath Singh held a review meeting with senior officials of the Ministry of Defense via video on Tuesday. The participants included the Chief of Defense Staff, the Commanders in Chief of the Army and Navy and their secretaries.

DRDO sets up its own hospital

Singh called on the armed forces to maintain close contact with the state government, ready to provide them with any assistance at any time.

According to a statement issued by the Ministry of National Defense, the technology of the “Glorious” warfare oxygen equipment can achieve an oxygen production speed of 1,000 liters per minute. The Uttar Pradesh government has ordered five equipment using this technology.

During the meeting, the chairman of the Indian National Defense Research Organization, Dr. Thaxi Shi Ledi, said that the organization can provide more oxygen generators to meet the needs of the hospital.

The article said that in order to make up for the large shortage of oxygen cylinders, DRDO has developed a blood oxygen saturation supplementary oxygen supply system, which can be used by soldiers stationed in extremely high altitude areas and can also help patients with new crowns.

Inferior performance of the brilliant fighter

“In the current COVID-19 pandemic, this type of automatic supply system will become a boon for patients.” India’s Ministry of Defense said in a statement.

The statement also said that the system was developed by DRDO’s National Defense Bioengineering and Electromedicine Laboratory (DEBEL) in Bangalore. It can provide oxygen based on the blood oxygen saturation (SpO2) level to prevent patients from falling into a hypoxic state.

DRDO configures an oxygen generation system for Guanghui

Dr. Ledi further stated that soldiers in extreme high-altitude areas face insufficient blood oxygen saturation similar to those of patients with new crowns.

The famous Roman arena in Italy Referring to the Roman arena, people often talk about a large area that can accommodate tens of thousands of people with ancient and beautiful designs in Italy. But recently archaeologists discovered a Roman arena in Turkey, very similar to the famous one in Rome but much smaller in size. Arena in Turkey used to host gladiator matches about 1,800 years ago with a capacity of 20,000 people. Meanwhile, the Roman arena in Rome began construction in AD 70, when the Vespasian emperor, with a total capacity of about 50,000 to 80,000 spectators. Archaeologists locate the arena amidst the ruins of the ancient city Mastaura, Aydin province. The arena was partially buried and obscured by vegetation. Ancient roman arena discovered in Turkey The building has gladiator lounges and guest rooms. The whole monuments are preserved in good condition. Like the Roman arena in Italy, the arena in Turkey was built in the shape of a circle, instead of the typical semicircle of many ancient buildings.
Archaeologist Sedat Akkurnaz of Adnan Menderes University, who led the study, said the discovery was unique. Sedat Akkurnaz said: “This is the only example of such a solid existence in Anatolia. The structure is difficult to detect because it is heavily obscured by bushes, wild trees. Most of the arena is below ground. The arena is very sturdy as if it had just been built, meanwhile, the rest of the structure is on the ground, consisting of several rows of arena seats and external support walls. The dome-building technique of Roman architecture looks very good. Archaeologist Sedat Akkurnaz also explained that the arena is the venue for gladiator battles and wildlife. Near the old city of Mastaura, there are many major cities in western Anatolia such as Aphrodisias, Miletus, Priene, Magnesia and Ephesus. Therefore, people from neighboring cities also come to Mastaura to witness the battles with their own eyes. Part of the wall of the ancient arena in Turkey Experts believe that the arena in Turkey was built during the reign of Severan dynasty, during the Roman empire. This royal lineage includes the infamous Caracalla, his father Septimius Severus, who died in York after his campaign to conquer Scotland. Archaeologist Sedat Akkurnaz said: “We do not know exactly who the emperor was. But through the stone construction, the construction of the building, I think it was at the same time as the Severus dynasty. The city of Mastaura was very prosperous and prosperous. It was during this period that the Roman administrators greatly helped the city. There was a considerable increase in the number and variety of Mastauran coins during this period ” . Although the arena in Mastaura cannot match the structures in Rome in terms of scale, it is still a remarkable area. Sedat Akkurnaz said: “At this stage, it is difficult to accurately or approximate the audience. Our initial estimate was between 15,000 and 20,000. The gladiators had their own lounges, the audience was excellent. first has entertainment room “. In the near future, with the support of the local authorities, they will take action to conserve the parts most at risk of failure. According to Sedat Akkurnaz, there are cracks in the walls of the building, some of the stones are falling.

Company Kronstadt (Russia) is building a factory for the manufacture of unmanned fighter jets. (Source: Sputnik) The Kronstadt Company is the developer and manufacturer of the Inokhodets combat drone (UAV). Such aircraft can carry weapons up to 200 kg and have been used in the Syrian battlefield. In addition this type of UAV also has reconnaissance and civilian versions. “The Kronstadt Company has started building the first factory in Dubna to mass produce unmanned fighters. The factory will be built in record time when production is scheduled to begin in November. 2021, “said the company’s press department. The project has an investment capital of nearly 52 million USD and will provide permanent jobs for more than 1.5 thousand people. With an area of ​​45 thousand m2, the factory will have an environment-friendly and no-noise production process. According to a senior source in the Russian Industrial-Military Complex, “The project will meet the Inokhodets demand of both the Russian Ministry of Defense and other customers”. The Inokhodets, also known as Orion, was developed at the Kronstadt company by the order of the Russian Ministry of Defense. This device can fly continuously for up to one day. Its maximum take-off weight is 1,100 kg, combat payload is up to 200 kg. Orion is capable of using small guided missiles and guided bombs to strike ground targets. In addition, the Kronstadt Company is also developing the Grom heavy attack UAVs. (According to Sputnik)

The Russian Ministry of Defense on April 16 released a video of a MiG-31 interceptor deployed to monitor and escort a US Air Force RC-135 strategic aircraft reconnaissance as it approached airspace. Russia in the Kamchatka region.

In the video, the MiG-31 flies at a fairly high speed, passing the nose of the RC-135 at a close distance. “After the foreign military aircraft turned to leave, the Russian fighters have returned to a safe base,” the Russian Ministry of Defense added.

The Russian side has said it will “not allow” any violation of the border to occur. The time of the encounter is unknown, but almost a week ago, on April 10, the Russian side also deployed a MiG-31 to chase away US RC-135 aircraft operating near the Russian border. Pacific.

The incident comes in the context of an escalating tensions between Russia and the US following rhetoric, as well as the West’s criticism of Moscow to increase its forces to press Ukraine.

The MiG-31, designated by NATO as Foxhound, has been in service with the Soviet army since 1982, seven years after its maiden flight in 1975. Despite its relatively high age, the MiG-31 is still a battle. fastest match in the world when reaching a maximum speed of Mach 2.83, about 3,000 km / h.

The MiG-31 is currently in service with the Russian Air Force and the Kazakh Air Force. This is the first fighter in the world equipped with a passive electronically scanned array radar (PESA), allowing 24 targets to be tracked and 6 targets simultaneously.

According to Sputnik, a squadron of four MiG-31s ​​can manage 800km2 of airspace, suitable for the vast Russian airspace. The MiG-31 is also an aircraft modified by Moscow to be equipped with the Kinzhal supersonic attack missile.

After President Biden came to power in January, the US State Department asked to reconsider the deal passed under former US President Donald Trump. Previously, there was a lawsuit asking to block the deal on the grounds that the UAE was involved in a conflict in Yemen and supported General Khalifa Haftar’s forces in Libya. In this regard, the US State Department said it planned to conduct a candid and continuous dialogue with the UAE.

In the statement, the State Department spokesperson stated that the US administration intends to launch the sale of fighter jets to the UAE, along with reviewing the details, consulting UAE officials to ensure said the two sides to understand the UAE obligations before, during and after delivery. The handover deadline will be in the next few years.

House Foreign Affairs Committee Chairman Gregory Meeks has expressed concern about the deal. According to this congressman, since the handover of the aircraft will not take place soon, the National Assembly will have plenty of time to evaluate whether to proceed with the deal, as well as whether to impose terms or arguments do not have any restrictions.

If the deal is enforced, the UAE will be the first Arab country to receive F-35 fighters, aircraft capable of gathering intelligence, attacking deep into the territory of the target and combat in the air. Under the plan, the UAE will receive 50 F-35s, equivalent to the fleet size of Israel.

According to Defense World, the US Air Force recently announced blueprints for a new fighter jet being developed under the “Next Generation Aviation Advantage” (NGAD) program, which includes including unmanned and manned fighters.

The image shows a triangular flying fighter and its aerial weapons on display as well. The configuration of this fighter is also very different from today’s fighters, the plane is relatively flat, triangular seen from above, has a pair of vertical V-shaped tails and the air intakes located above. fuselage.

The photo shows that this fighter jet has very highly modular characteristics, can quickly replace engines, landing frames … thereby reducing the load of logistics maintenance, missile pods inside. The aircraft is also equipped with a variety of missiles.

The NGAD program was originally proposed as a joint project of the US Air Force and Navy. Although there is still some joint cooperation between the two sides, each side has in turn set up independent offices to research and develop next-generation fighters.

From 2019 to 2025, the budget for the NGAD program of the US Air Force is 9 billion USD, of which the budget for the fiscal year 2021 is 1 billion USD and the budget of the fiscal year 2022 is 1.5 billion USD.

According to the report, the NGAD program aims to complement the F-22 and F-35 fighters, creating a system with multi-domain cognitive capabilities, flexible information and strong operational advantages. air raid attack. The program will apply digital technology to large-scale fabrication and replacement of small components.

This approach is based on the automotive industry’s digital transformation and uses models to solve design, assembly, maintenance and repair issues before, the Air Force said. build a physical system.

The US Air Force report did not specify the cost of the project to build the aircraft. However, the report mentions that a mysterious jet under the project was tested in 2020, and it is still unclear whether the plane is manned or not.

“We have built and tested a new aircraft and broke all aircraft records,” said Will Roper, Assistant Secretary of the Air Force for US logistics and technology equipment procurement. fight. We are now ready to build the next generation aircraft in an unprecedented way. “

Some previous reports suggested that the NGAD program plane will have an artificial intelligence co-pilot, maybe even the ARTU system (artificial intelligence system built by algorithm to play chess. ).

The artificial intelligence system will act as a support for true pilots, but the weakness of AI systems lies in their logic, while actual military actions may not obey this logic. Human presence is then required to make a decision in unusual, non-standard situations.

It is known that from March 2018, the US Air Force Laboratory has released the image of the next generation F / X aircraft, showing that this aircraft will have a stealth design, eye-catching appearance with laser. High energy capable of cutting enemy aircraft in half.

This is also the main aircraft in the NGAD program, also known as the Penetration Jet. The future F / X aircraft is expected to have longer range and payload, as well as the ability to carry hypersonic weapons.

Under the NGAD program, the US Air Force advocates to exploit advanced capabilities of the new generation of aircraft such as air combat systems linked to fighters, drones and networking platforms. . With the aim of increasing air superiority, the F / X fighter program offers significantly enhanced stealth and works closely in coordination with the drone.

Until now, all information about the capabilities of the F / X is still a military secret. If the program progresses at a rapid rate through streamlined processes and uses current technology, the new generation fighter could join the US Air Force earlier than expected in 2030. .
