As the situation in the Taiwan Strait heats up, China Air Force research expert De Sinoe, a well-known American, posted high-definition pictures of China's latest third-generation semi-fighter J 1 1BG on his social media. In the picture, many specific details of fighter J 1 1BG are very obvious, and the iconic pure white radome is very conspicuous.
In addition, this fighter J- 1 1BG also mounts the training bomb of the PLA PL 10 close combat bomb without missile wings. Moreover, from the vertical tail number analysis of this J- 1 1BG, we know that the newly installed unit is actually an aviation brigade unit under the jurisdiction of the Central Theater, and it has been equipped with J- 1bg fighters until it is replaced with J-1BG fighters.
At present, the most equipped type of flanker fighter in the Air Force is the J- 1 1B fighter. Compared with the J- 1 1A fighter which completely copied the Soviet 27SK and gradually retired, the J- 1 1B fighter is a self-made heavy multi-role fighter. Aircraft materials, power system and fire control system are basically domestic equipment, completely replacing the J- 1 1B fighter made in China. Compared with the original Russian Su -27 and the imitation J- 1 1A, the performance has been obviously improved.
J 1 1B is lighter and more flexible than j11a. J 1 1B Due to the improvement of radar performance, more air targets can be detected and strike operations can be launched. In addition, J 165438 has the ability to strike the ground and the sea.
The J 1 1B fighter is also the third-generation semi-heavy multi-role fighter J1/PLA family with the largest output in China. It is mainly used in maritime and air force combat units, but with the passage of time, the J 1 1B fighter with air combat capability gradually lags behind other new models of the PLA. For example, the J-116 fighter derived from J-1BS, or even the medium-sized J- 10C fighter, can be said that J- 1 1B can no longer be regarded as the top three-generation semi-fighter in air combat performance.
In recent years, more advanced active phased array radar, new avionics and electronic warfare systems, and new PL- 10 and PL- 15 air-to-air missiles have been widely used in other advanced fighters replaced by the PLA, which has improved the combat effectiveness of the new fighters in all aspects compared with the old fighters. And J- 1 1B's air combat capability is a bit difficult because of the lag of radar and fire control system.
On the other hand, Shen Fei also began to develop a more advanced J-/KOOC-0//KOOC-0/D multi-role fighter based on J-/KOOC-0/B. Compared with J-11b, J- 1 10B is equipped with a new type of active phased array radar, which greatly improves the avionics and successfully makes its first flight. Unfortunately, the research and development of J- 1 1D has been terminated.
The reason may be that it is not cost-effective to replace J- 1 1B with a new machine. At present, the J- 1 1B fighters equipped by the PLA are only a few to ten years old at most, and the aircraft is in very good condition, so it is impossible to retire early. In addition, if mass production of 歼 1 1D replaces these 歼 1b, although the 歼 7 歼 8 equipped by other troops can be replaced by 歼1b, the performance problem cannot be fundamentally solved.
Therefore, Shen Fei transplanted J 1 1D to J 1b, and upgraded it directly. The upgraded version of 歼 1 1B was called 歼1BG fighter. It can be said that this step, the J 1bg fighter.
It is said that J 1 1BG upgraded J 16, and greatly upgraded the avionics, fire control and electronic warfare equipment of the aircraft. The overall upgrade of 歼 1 1BG greatly improves the air combat capability and multi-purpose capability. 歼 165438+ can carry the most advanced PL- 10 and PL- 15 air-to-air missiles of the PLA, and further improve the over-the-horizon air combat capability and close combat capability.
With the improvement of radar system performance, J- 1 1BG can become one of the strongest three-generation semi-fighters at present, and J-1/BG can theoretically carry PL-2 1 air-to-air missiles with longer range for ultra-long-range interception operations. These are J- 1 1bg. It can be said that the current upgrading project 歼 1 1BG is of great significance for improving the overall performance 歼1BG fighters equipped by the Air Force. With more and more J-J 1 1bg fighters being modified and upgraded to J-J 1 1bg, it is expected that the strength of PLA heavy fighter will be greatly improved.
Now, according to public information, the western theater, the central theater and even the HNA troops have gradually installed J- 1 1BG fighters, which is comparable to exchanging guns for guns. This also shows that the upgrading speed of PLA fighters is accelerating, and its conventional fighter units are gradually moving towards the top level of the third generation fighters.
