J-11 is still the main force of the Air Force
At present, our Air Force has entered the stage of transition from third-generation aircraft to fourth-generation stealth fighters, and at the same time retains a certain number of second-generation fighters. The Air Force currently has three main fighters that are widely known, namely the F-20, F-10C and F-16. Among these three fighters, the F-20 is the high-end model with the strongest air superiority performance, and the F-16 is a multi-functional combat "all-rounder". , J-10C is a homeland air defense fighter with relatively low equipment cost.
The above three fighters have one thing in common, that is, they are equipped with the most advanced domestic active phased array radar, avionics system and weapon system. But in addition to these three fighters, the Air Force also has a J-11 heavy fighter that seems to be forgotten. In fact, the total number of F-11A and F-11B is close to 300, and the range of long-range ammunition is large. These hundreds of F-11 occupy a quarter of my country's three-generation fighters in scale and are still one of the main forces of the air force. !
Why has the J-11 not been fully upgraded?
The J-11 is a dual-engine heavy fighter, and retains the excellent aerodynamic layout of the "flanker". From the perspective of the fighter platform alone, the J-11 surpasses the J-10, but the current J-10 series of the latest J-10C is equipped with new models The avionics weapon system has surpassed the J-11 series fighters in performance, especially the active phased array radar equipped with the J-10C has a detection range far beyond the mechanical scanning radar of the J-11, so the domestic airborne radar is already very mature. Next, why has the J-11 series fighters not been fully upgraded to improve performance?
In fact, it doesn't make much sense to simply replace a fighter with radar! The radar performance of a fighter jet is reciprocal with its airborne avionics system. The avionics system can’t keep up and can’t perform the best when it’s equipped with a radar. The avionics system will also be fully upgraded. After the avionics radar is upgraded, the weapon system will also be upgraded. That is to say, if the F-11 series is replaced with a radar, it is actually a comprehensive upgrade. This upgrade is under the conditions of mature technology. It is not difficult, but it takes up resources.
Future upgrades may only target the J-11B
At present, the Air Force’s focus is on the mass production of the F-20, F-16 and F-10C. After these three fighters reach a certain number, it is imperative to upgrade the F-11 series. In fact, the upgrade of the F-11 series has been preliminary. Unfold, such as the J-11BG fighter. But one of the problems is: the J-11 series fighters are large in scale, and there is no need for a comprehensive upgrade. Among nearly 300 fighters of the J-11 series, the J-11A accounts for about one-third, and the rest are all J-11B/BS.
The J-11A is a domestically produced version of the Su-27. It has been in service earlier and has a lower level of equipment than the J-11B. Therefore, the upgrade of the J-11A will be relatively more complicated. In contrast, the upgrade of the J-11B is simpler. The workload of upgrading more than one hundred F-11Bs is also very large, and if all these F-11Bs are upgraded, it means that the Air Force will have more than a hundred three-generation and a half fighters with overall performance exceeding the F-10C. Therefore, it is not necessary to fully upgrade the J-11 series. Only the J-11B can be upgraded to greatly enhance the overall strength of the air force.
