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.

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)

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.

Pilot Wang Zunxi (a fairly well-known PLAAF officer) in an interview with China Central Television (CCTV 7) gave a very remarkable point of view. According to the veteran pilot, the multi-purpose fighter J-16 manufactured in Shenyang Aircraft Corporation and is being massively employed for PLAAF combat units of generation 4 ++. “J-16 fighter jets (including the J-16D electronic warfare version) have surpassed Russia’s Su-30 series heavy multi-role fighters in almost all tactical specifications. “. “The superiority shown in both avionics and electrodynamic properties, the radar reflection area reduction coefficient (RCS), the J-16 retains only the aerodynamic layout of the airframe”, pilot Vuong said clearly. Faced with the above situation, the Russian press stated that in order to seek export contracts or bring high morale and psychological state to the soldiers, the weapons manufacturers used very sophisticated promotional tools and are not always objective. Russian military experts rebuttal when emphasizing that the Chinese pilot is comparing the technical specifications of the electronic equipment on the Su-30MKK and Su-30MK2 fighters that are somewhat out of date. These fighters were supplied to the PLAAF 20 years ago, and they are actually significantly inferior to the J-16 when facing exercises (both for surface attack and long-range interception missions). ). The reason is that China’s Su-30 integrates the N001VE passive phase array radar (PESA), which ensures the realization of “truncated” synthetic aperture and “truncation” (SAR) mode with low resolution. , only allows the detection and classification of targets with large RCS parameters. In addition, the capacity and anti-interference ability of the N001VE radar is quite low, it can only catch the 1m2 RCS aerial target, 75 – 80 km away in case the enemy does not use electronic countermeasures. In fact, the J-16’s high energy and anti-interference active phase array (AESA) radar has a target capture range with 1 m2 RCS from 130 to 150 km, and high anti-interference ability, range is only slightly reduced in a highly noisy environment. This is due to the presence in the electronic architecture of the advanced AESA radar, which consists of more than 1,500 transceiver modules, each equipped with an individual arsenide / gallium nitride microwave transistor. Moreover, this type of radar is also capable of operating in synthetic aperture (SAR), reverse synthesized aperture (ISAR) and tracking ground targets moving in real time. Although the equipment for the J-16 is very advanced, the Russian side thinks that it is necessary to compare the J-16 with more modern modifications, for example the Su-30SM2 variant is about to enter service. Although the N035 Irbis radar that will equip the Su-30SM2 of the PESA class may be significantly inferior to the J-16’s AESA radar in terms of interference resistance, the capacity is higher (providing target acquisition range. with 1 m2 RCS at a distance of 250 – 270 km). With the N035 Irbis radar, the Su-30SM2 will have the ability to “foresee and shoot before” the J-16 in a direct confrontation situation, especially when Russia is still completing the long-range air-to-air missile “product. 180 ”. But it must be noted that the Su-30SM2 is still on paper, while the J-16 has been on duty for many years and there is no guarantee that the Russian fighter really possesses outstanding features. as they still publish.
