While the US AH-64 has performed excellently both in combat and in the export market, the Russian Mi-28 has only Iraqi and Algerian customers. The idea that Mi-28 will be chosen by India, however, in the end New Delhi chose the US AH-64. Mi-28 is also a line of attack helicopters with a long development time when the first flight appeared in 1982, but it was not until 2009 that the version capable of day and night combat entered service. After having an unimpressive first field trip in the Syrian battlefield, Russia has continued to upgrade to produce the Mi-28NM version. Currently in Russia’s official payroll, there is a Mi-28A version that is only capable of daytime combat, this version is not appreciated; Mi-28N is a version capable of fighting in all weather conditions including night and the upgraded version of Mi-28NM has only been commissioned in small numbers. To be fair, the Mi-28 is a line of heavy attack helicopters capable of delivering devastating blows to the enemy. However, the Mi-28 did not live up to expectations when it was designed to replace the Mi-24s. In the Syrian battlefield, the Mi-28N did not even prove superior to the Mi-24. This made many Russian generals criticize the developer. Perhaps that is why the manufacturer Mil bet on the Mi-28NM version. Compared to its predecessor, although there are not many major changes in appearance except for the nose, the changes brought from the inside have helped this aircraft achieve high combat performance. Weapons analysts said that with the introduction of the Mi-28NM version, the attack helicopter line was enough to line up with the latest US version of the AH-64E. There have been reports that the Mi-28NM was secretly brought to Syria to test fire by Russia to evaluate its combat performance and obtain positive results. It was from this real combat test that Russia quickly decided to put the Mi-28NM into mass production. In terms of structure, the cockpit of the Mi-28NM is reinforced more firmly, with an air-conditioning system, with additional protective armor, including a metal front windshield that is resistant to 12 bullets, 7 mm. The cabin has an additional layer of glass that separates the compartment between the two pilots, minimizing the possibility of the main pilot and the pilot pilot dying at the same time from enemy fire. The alloy frame of the Mi-28NM is able to withstand 20mm anti-aircraft shells. With the design applied on Mi-28NM, for the first time the principle of separating the cockpit between the main pilot and the pilot pilot has been applied. In the event of an emergency when the plane is above 100 m above the ground, the crew can parachute out when the plane crashes and crashes. The emergency exit system will be activated by the main pilot and the pilot pilot separately. According to Mr. Dmitry Litovkin, CEO of Independent Military Review, Mi-28NM is an attack helicopter version with enhanced tactical features, especially combat power. The helicopter is equipped with high-precision weapons, has a new control system integrated with artificial intelligence (AI). Mi-28NM is compatible, join the battle formation with helicopters, UAVs and other aircraft on the battlefield. In terms of firepower, the Mi-28NM heavy attack helicopter is equipped with a variety of powerful weapons systems, including new-generation multipurpose missiles and various bombs. The helicopter can attack stationary and moving targets within a radius of 8-10 km. Mi-28NM has a new LSN-296 aiming system, which can control two of Russia’s most powerful anti-tank missiles today, Khrizantema and Vikhr. The pilot of the Mi-28NM is equipped with a flying helmet with a specially designed target indicator system, displaying panoramic information to aim at targets in all directions. Mi-28NM is equipped with Nadterechny Н025 radar as well as a new generation of aiming and guidance complexes, including a control system for landing in dark and foggy conditions, which helps to improve combat efficiency. almost twice that of its predecessor. In the design of the Mi-28NM, the position of the radar transceiver remains above the main rotor of the helicopter. In addition to the upgraded avionics and body frame, the other difference is that the propeller of the Mi-28NM uses composite materials to make the helicopter more stable, the new engine is stronger but more fuel-efficient than that of the Mi-28NM. Predecessor. In addition, Mi-28NM is also equipped with a suicide drone. Helicopters can enter a predefined combat area and launch one or more drones from the cockpit. Once the target has been identified, the crew will report the data and monitor the kill launch process. Mi-28NM is capable of operating in all weather conditions, can fly in both automatic and manned modes, adapts to all kinds of terrain. One of the most practical improvements in the Mi-28NM is the crew’s “double control” mode. In the event that the main pilot is injured or killed, the pilot can still control the helicopter. Another improvement is that Mi-28NM is equipped with an additional radar system on the cockpit, capable of scanning around the aircraft, with a scanning angle of up to 90 degrees horizontally and 44 degrees vertically, helping detect and locate multiple targets at the same time. With such top-notch features, Russia’s Mi-28NM is expected to create a breakthrough in the combat capabilities of the Russian military as well as in the export market.

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.

Mi-28NM is capable of operating in all weather conditions, performing many tasks including armored attack, destruction of low-speed air targets, reconnaissance… This latest version will be released. introduced at the MAKS-2021 Military Show this summer. The performance of the Mi-28NM combat helicopter’s complex skills will be one of the most awaited activities. Mi-28NM combat helicopter. Photo: RBTH The Mi-28NM made its first flight at the end of 2016 and has undergone state tests over the past few years. In June 2019, the Russian Ministry of Defense signed a contract for the supply of 98 aircraft of the Mi-28NM version. The first batch was delivered to the army in 2020. The production of Mi-28NM was also carried out at the Rostvertol plant. “The Mi-28NM helicopter has undergone an upgrade and modification process after the “fire test” in Syria. Engineers have tested the Mi-28NM helicopter in real combat conditions to present to the public a version of the most powerful combat helicopter in the Russian air force,” said Professor Vadim Kozyulin at the Institute of Military Science. Russia said. What’s new in Mi-28NM? The new cabin of the Mi-28NM is protected by armor, including tempered glass in front that can withstand 12.7mm bullets. The armor barrier between the non-crew members also limits the ability to deal consecutive damage to both pilots. This baffle can withstand the impact of 20mm bullets. This is the first time on the Mi-28 helicopter that there is a partition between the two main pilots and the co-pilot. The pilot and copilot emergency exit systems can be activated separately. Mi-28NM has been “fired” in the Syrian battlefield. Photo: RBTH “The Mi-28NM is the latest version of the Mi-28N helicopter. It is enhanced with many capabilities, including mobility. The new helicopter is capable of using high-precision weapons, has a new control system with integrated AI. Mi-28NM can interact with helicopters, UAVs and other aircraft on the battlefield,” said Dmitry Litovkin, Executive Director of Independent Military Review. The “weapon” of the Mi-28NM helicopter also includes kamikaze drones – a type of suicide UAV. “The Mi-28NM can deploy and control one or more suicide UAVs. When hostile objects are detected, the pilots will provide target data and monitor the removal of those targets,” the expert said. The Mi-28NM helicopter can operate in difficult weather conditions, capable of flying in both piloted and automatic modes. One of the key practical changes for the pilot on the Mi-28NM is the dual control mode: in the event of a primary pilot’s injury or death, the co-pilot can continue to control the helicopter. Mi-28N does not have this mode. According to publicly available information, the main difference of the Mi-28NM is that it is equipped with a radar and thermal imaging support system, with the ability to scan around the aircraft instead of a few directions. Mi-28NM has a huge arsenal, including new generation multi-purpose missiles, including those launched beyond the enemy’s air defense identification zone, as well as various types of bombs. The helicopter can attack fixed and moving targets within a radius of 8-10 km.

Tesla ditches radar sensors on self-driving systems. Photo: Getty Images No company in the auto industry can attract as much attention as Tesla, on the one hand because of CEO Elon Musk’s controversial statements, on the other hand, because Tesla regularly makes “unusual” decisions. “. At the end of May, Tesla once again became the focus of public opinion, and this time not because of a “brake failure”, but a configuration change. Recently, Tesla announced that starting in May, Model 3 and Model Y in North America will no longer be equipped with sensor radar, cancel the millimeter wave radar in front of the vehicle and only use the camera as a receiver. data collection of automatic driving systems. This means that Tesla is poised to be the first car company to deploy a “pure vision” autonomous driving solution. Meanwhile, other self-driving car manufacturers are integrating radar, LiDAR and cameras in autonomous driving systems. In fact, Tesla CEO Elon Musk has always been adamant against LiDAR, even repeatedly criticizing LiDAR in public. He thinks this is an expensive, unnecessary technology. Even Elon Musk has called those who believe in LiDAR technology “stupid” and car manufacturers using LiDAR technology will never achieve success. So, why is Musk so adamantly “disliked” LiDAR and even all radars, and only favors a camera technology solution? To clear this up, we may need a basic understanding of autopilot schematics. Camera and LiDAR To build a set of automated driving system solutions, the automatic driving algorithm is of course inseparable. In order to achieve calculations, sufficient information is required first. During driving, the vehicle’s information collection source is the large and small sensors on the body of the vehicle. Among them, to realize autonomous driving, the most important sensors are the camera and LiDAR (must add millimeter wave radar and ultrasonic sensor, of course). Therefore, the autonomous driving system is divided into camera-based vision array and LiDAR array. “Camera-based vision” uses a high-definition camera incorporating an image recognition algorithm, while LiDAR to ensure system stability. The camera array, or pure visual diagram, is essentially a complete simulation of the state of a person driving a car, first seeing the image with the “eye (camera)”, then transmitting it to the “brain (processor)” for processing and judgment, and then give the action “Legs (steering mechanism)”. In addition to Tesla, Chinese companies including Jikrypton and Baidu have also adopted pure vision solutions. LiDAR technology uses a laser to measure distances and build a 3D map of an object, by emitting and receiving the laser’s feedback and then analyzing that data to produce the desired results. Many Chinese car companies including Xiaopeng, Weilai, BAIC ARCFOX, and many other new products also announced this solution. Which solution is better? The advantage of the “pure vision” solution is that the video data captured by the camera is the closest to the real world perceived by the human eye, and also the closest to the form of human driving. At the same time, with LiDAR prices currently very high, a pure vision solution using only the camera should be easier to control costs. Tesla’s pure vision algorithm analysis is already very strong. In addition, the image obtained by the camera is well suited for object identification and classification, in case the algorithms are excellent, it can remove confounding items and enable automatic learning during driving. car. However, as a visual algorithm similar to the human eye, the camera is easily affected by light, in harsh weather or poor lighting conditions, it is easy to cause misjudgment. Previously, when AutoPilot was turned on, Tesla models accidentally braked automatically when going over an overpass or under a normal bridge, due to the algorithm using a sudden ball in the camera as an obstacle. Rendering a 3D environment map drawn by LiDAR Compared with pure vision solution, the advantages of LiDAR solution are longer monitoring distance, higher accuracy, more sensitive response speed and unaffected by ambient light. LiDAR’s three-dimensional information processing, object size calculation, and movement speed are more efficient. However, LiDAR has problems such as weak object recognition, high cost, and accuracy in extreme weather conditions such as rain and snow. Therefore, LiDAR must be used in conjunction with other sensors to ensure safe driving. In addition, the collection of large amounts of data requires high computing power of the processor, which equates to an increase in the cost of the media processor. Theoretically, the combination of camera-based vision and LiDAR is a relatively complete solution today, but after combining many factors such as existing technology and product cost, it is too difficult to use. use a “third solution” that integrates these two major solutions. Tesla’s trade-off The cost of LiDAR is much higher than high quality cameras. In fact, abandoning LiDAR, and even now abandoning millimeter wave radar, one of the key reasons Tesla made such a choice was to achieve lower costs. After all, the cost of LiDAR is very high, the price of this technology in the early days started at 100,000 USD, but now with the development of the electronics industry, its price has decreased but basically remains the same. maintained at several tens of thousands of dollars. However, compared to high-definition cameras, the price of only a few hundred dollars is still much higher. However, besides cost, Tesla also has technical trade-offs. First of all, LiDAR does not determine the specific nature of the object, so it is easy to cause wrong judgment. For example, if a large plastic bag appears in front of the vehicle, the camera solution may recognize it as a plastic bag and ignore it, but LiDAR will judge it as an obstruction and stop the vehicle. Second, millimeter wave radar also has many limitations. The detection range of millimeter wave radar is directly limited if the band is weak. It cannot identify pedestrians nor accurately model all surrounding obstacles. At the same time, due to the large amount of data obtained, it will also consume precious computing power of the processor. Finally, for Tesla, the best company in imaging solutions, they have invested heavily in imaging algorithms. To give up the large accumulation so far, and turn to another path, in terms of input – output ratio, it can be said that it is not worth it. Tesla is loyal to a completely camera-based vision solution Tesla Vsion camera system. On Tesla’s official North American website, during the introduction of Full Self-Driving FSD, the performance information of the millimeter wave radar was removed and only the image sensor and ultrasound. At the same time, Tesla also released the driver monitoring system on May 28. The Model 3 and Model Y vehicle cameras can monitor the driver’s behavior when the Autopilot system is activated, detecting and reminding the driver to keep his or her attention. Tesla states that “camera data will be stored in the vehicle, and the system will not send the data back to the company unless the user gives permission to share the data”. In addition, Tesla’s FSD V9.0 autopilot system will also be officially launched this year. According to Musk’s earlier statement, the FSD algorithm has been “refactored” to achieve pure vision through 8 cameras around the body, while effectively solving the previous “brake failure” problem. Tesla also warned that Autopilot and FSD systems would be less effective during this technical adjustment period. “During a short period of transition, Tesla Vision vehicles may experience some limitations or inactivity, such as Autosteer being limited to a top speed of 120.7 km/h. , Smart Summon (if equipped) and Emergency Lane Avoidance may be disabled during delivery,” Tesla’s announcement reads. Whether LiDAR will win the market with a secure advantage in the future, or a camera-based vision algorithm dominates the market with a lower cost advantage, the answer is still unclear. However, judging from the information currently available, Tesla will choose to stick with a pure vision solution.

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.

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.

Taiwan Air Force F-16. The Taiwanese military has announced plans to sell its old F-16 radars after Taipei’s fighter squadron received new radar systems. Taiwan’s F-16 fighter aircraft is being upgraded with the new AN / APG-83 AESA radar as part of the retrofitting of the F-16 Block 70 version. However, the old APG-66 radars are still serviceable and valuable in the international arms market, Liberty Times reported. A source familiar with the matter has pointed out that APG-66 radars could also be installed on F-16A / B fighter jets, which are still in service with foreign air forces. After Taiwan completes the retrofit of its jets, a batch of more than 100 APG-66 radars will be sold in accordance with US regulations, with profits transferred to Taipei’s treasury. The value of the old radars has yet to be determined, the source said. Taiwan purchased 150 F-16 fighters from the US in 1992 and received them in 1997. According to the Northrup Grumman group, the new AN / APG-83 features high-resolution synthetic aperture radar mapping in all weather conditions to show pilots a large surface image for item identification. target and more accurate attack information.

“The MiG-35 has completed the integration test and received a very positive response from the pilot. There are only a few minor defects that need correction before the MiG-35 officially joins. training and combat in the Russian Air Force, “said a representative of the manufacturer MiG. MiG-35 fighter. MiG-35 fighter (NATO designation Fulcrum-F) is designed to operate in all weather conditions. Can strike air, land and sea, whether it’s a static or dynamic target. Recently, the Russian manufacturer announced the development of a new profile MiG-35D. An impressive showcase version but it’s not really a new platform. Because they are only developed based on the prototype MiG-29KR from the Soviet era. “The name MiG-35 is essentially the Russian manufacturer’s clever intent to market to the market because the number 35 makes many people pay attention to the same power as the Su-35 – a product of the manufacturer Sukhoi or Lockheed Martin’s F-35. But apart from the number 35 with the above fighters, the MiG-35 hardly performed much in the Russian Air Force’s tests and exercises, although they were integrated with the most advanced technology. Now compared to fighters of the same generation, “wrote Peter Suciu. The manufacturer equips the MiG-35 with the Phazatron Zhuk active phase array radar, and the RD-33MK engine pair allows the aircraft to reach maximum speeds of up to Mach 2.5. In terms of weapons, this fighter jet is designed with 9 armaments under the belly to help it carry most types of bombs and weapons available in the Russian Air Force including: Kh-31A anti-ship missiles with active radar probes, Kh-31P anti-radar missiles, Kh-29TE missiles and TV KAB-500Kr guided bombs … In addition, the MiG-35 is also equipped with a gun. 30mm high speed cannon. Information about the MiG-35 program has been known since 2007, but due to slow development, it was not until 2013 that the Russian Air Force announced an order for a plane for testing and evaluation before official. buy 37 pcs. But after 3 years, the manufacturer produced 3 more units. Thus, on average, each year MiG produces 1 MiG-35 fighter. At the current production rate, US experts say it is unclear whether the Russian Air Force will continue to pursue the 37-aircraft deal as agreed or not. This is also the reason why Indian customers have expressed special interest in this fighter line for a long time, but no agreement has yet been signed with the MiG manufacturer. The situation also appears to some customers in Africa and Southeast Asia. “A line of fighters produced for the purpose of domestic and export equipment, but this goal is difficult to accomplish with the MiG-35. Until now, no Russian fighter has produced any quality product. So hiu “, the American expert wrote. However, the MiG-35 is still highly appreciated by the Russian manufacturer. MiG affirmed that, although it is only a 4 ++ generation fighter, the MiG-35 fully converges the leading advanced technologies of the world military aviation industry. MiG-35 is highly competitive with the world’s leading fighters such as the Rafale, Typhoon … because MiG-35 dominates in this race because they have many outstanding features. The MiG-35 is more maneuverable, has more arsenal and is cheaper. Their specifications, avionics, electronic warfare equipment and arsenal allow the MiG-35 to compete with any kind of potential foe. With these systems equipped, in theory, it is not unreasonable for the Russian manufacturer to see the MiG-35 as a rival to the F-35.

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.

Russian long-range radar system. “It is known that the lower the frequency range, the greater the penetrability of the waves, so our radar shooting can be done not only through clouds, fog but also under foliage and camouflage vehicles. . Accordingly, if a forest can be optically photographed under ideal conditions, our radar will be able to penetrate the foliage and be able to see any objects in the scanning area. ” Said Ilya Kuzmin, engineer of the Institute of Micro Devices and Control Systems called LN Presnukhina of NRU MIET. With the help of radar, it is possible to generate images not only of the visible surface but also to give its extensive interpretation, determining, for example, the state of soil and vegetation. By attaching the platform to an aircraft or drone, it is possible to capture volcanic eruptions, earthquakes or collapsing buildings. The new radar-controlled aircraft will provide images from which not only can the scale of the disaster be assessed, but also the detailed examination of objects. This development could also serve as the basis for satellite radars and applications in both scientific and military research. In the future, the satellite could carry out radar surveys on large areas of the country and around the world. The new radar can also be useful in agriculture for tracking crop growth, soil conditions and even fruit ripeness. During ice exploration in the Arctic and Antarctic conditions, the radar will determine the thickness of the ice and suggest routes that the icebreaker can take. In addition, the new radar system can help monitor the pipeline and oil pipeline. Radar is not, of course, an instant image projection camera; These are the reflected signals that are digitally recorded on a hard disk and processed by software, explains Ilya Kuzmin. At the same time with the revelation of new radar technology, Russia has also put into service the first unmanned radar system to monitor all flight activities in an area of ​​300,000 km2. General Andrei Koban, Commander of the Radio Technical Force of the Russian Aerospace Forces, said that each system is equipped with 20 radar modules. Each module can scout an area with a radius of 450km. “Integrated radar system with 20 modules, automatically control the aircraft’s operation over an area of ​​300,000 km2”, said General Koban. In addition to airspace control, the Nablyudatel radar is responsible for navigation, providing flight routes for aircraft that pass through the area in which it operates. General Koban also affirmed that this is the first radar system in history that can operate fully automatically without anyone participating in the control. Currently, Russia has deployed at least two Nablyudatel complexes to areas with the highest and most complex air traffic traffic.

People in the Eastern Hemisphere can observe Apophis without binoculars by 2029. Exclude from the risk Asteroid 99942 Apophis was discovered in 2004. Apophis was quickly identified as one of the most dangerous asteroids that can impact Earth. However, that impact rating changed as astronomers tracked Apophis and its orbit. Now, results from a new radar observation campaign combined with accurate orbital analysis have helped astronomers conclude that Apophis poses no risk of impacting our planet in the least. at most a century. About 340 meters across, Apophis is quickly known to be an asteroid that could pose a serious threat to Earth. At that time, astronomers predicted that this asteroid would come close to Earth by 2029. Thanks to additional observations of a near-Earth object (NEO), the risk of impact by 2029 has since been eliminated. The scientists then also ruled out the potential impact risk posed by another close approach in 2036. However, a small chance of impact by 2068 is thought to still exist. When Apophis moved away from Earth on March 5, astronomers had an opportunity to use the radar observations vigorously. As a result, it helps refine estimates of the orbits of asteroids around the Sun with extremely high accuracy. Thus, scientists can confidently eliminate all risks of collision by 2068 and much later. “An impact in 2068 is no longer in NASA,” said Davide Farnocchia of the Center for Near-Earth Objects Research (CNEOS) managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California (USA). possibilities could happen again. Our calculations do not show any risk of impact for at least the next 100 years ”. Mr. Farnocchia mentioned the Sentry Risk Impact Table. Maintained by CNEOS, this table holds information about some asteroids whose orbits bring them so close to Earth that the impact cannot be ruled out. With recent findings, the Risk Impact Table no longer includes Apophis. Optical telescopes and ground radars help characterize every orbit of objects near Earth. As a result, scientists can improve long-term risk assessment. CNEOS calculated a high-precision orbit to support NASA’s Planetary Defense Coordination Office. Apophis is no longer a threat to Earth. Opportunity to “follow” Apophis Apophis is the size of three soccer fields, weighing 27 million tons. If it collided with Earth, it would cause an explosion that was equivalent to 880 million tons of TNT. This power could destroy a country of mid-size. Its impact with the Earth will be 65,000 times stronger than the atomic bomb that once fell on the city of Hiroshima, Japan. The impact hole it left could be 518m deep. To achieve new Apophis calculations, astronomers used 70 m radio antennas at the Deep Space Network’s Goldstone Deep Space Communications Complex near Barstow, California. As a result, they were able to accurately track Apophis’ movements. “Apophis used to be close to Earth, but it still has nearly 10.6 million miles (17 million km) to go. Despite this, we were able to obtain extremely accurate information about the distance of Apophis with an accuracy of about 150 m. This campaign helps us eliminate the impact of risk and a great scientific opportunity, ”said JPL scientist Marina Brozovic – who led the radar campaign. Goldstone also partnered with the 100-meter-long Green Bank Telescope in West Virginia to allow Apophis to be photographed. Goldstone transmits while Green Bank receives – experiment that doubles the strength of the received signal. Although the Apophis radar image appears in pixels, the image has a resolution of 38.75 m per pixel. This is a remarkable resolution, considering whether the asteroid is 17 million kilometers away, or about 44 times the Earth-Moon distance. As the radar team analyzes more data, they also hope to learn more about the asteroid’s shape. Previous radar observations have shown that Apophis has a “double layer”, or peanut-like appearance. This is a relatively common shape among asteroids near Earth that are greater than 660 feet (200 m) in diameter. Astronomers are also working to better understand Apophis’ rotation speed and the asteroid axis orbit. On April 13, 2029, the Apophis asteroids will cross less than 20 thousand miles (32 thousand kilometers) from the surface to closer to Earth than the distance of geotechnical asynchronous satellites. On that close 2029 approach, terrestrial observers in the Eastern hemisphere could witness Apophis without the aid of a telescope or binoculars. This is also an unprecedented opportunity for astronomers to get a close-up look at a monument in the Solar System. In particular, now, Apophis is just a scientific curiosity, instead of a danger to our planet. “When I first started learning about asteroids after college, Apophis was a malformed child among dangerous asteroids,” said Mr. Farnocchia. There is a certain sense of satisfaction to see it removed from the list of risks. We are looking forward to knowledge that we can explore in its up-close by 2029 ”.
