Theoretically, if two aircraft overlap, it is indeed possible to use the fuselage of the other aircraft to block the reflection of radar waves and thus make itself undetected by radar, but this is based on the fact that there is only one radar emission source.

The radar alert range of the aircraft carrier battle group is a multi-directional three-dimensional reconnaissance, you can avoid the radar of the early warning aircraft in the sky ahead, but there are radars of early warning helicopters and surface ships scanning on the side and below, as long as a radar wave is reflected back, you will definitely be detected. Therefore, the possibility of using stealth fighters to break into the aircraft carrier within 200 kilometers without being detected is almost non-existent. It is precisely because of this that Chen Guofang is so angry.

Mu Shaoqing was even more depressed to death, no matter how he tried to break his head, he couldn't figure out how Xia Yu and Wang Pengyu could not be discovered by any radar, so they approached the aircraft carrier 120 kilometers. As the commander-in-chief of the flight, Mu Shaoqing naturally knew what it meant for the aircraft carrier to be approached to 120 kilometers by two fighters.

The engineers of the test flight team quickly extracted the flight data and sent it directly to Mu Shaoqing. Mu Shaoqing, who was in a hurry, directly ordered the technical engineers on the aircraft carrier to build a three-dimensional model as quickly as possible to simulate the situation at that time. Two days later, a slightly rudimentary 3D animated video came out.

The senior command layer on the aircraft carrier sat in the mission briefing room almost one by one, watching Xia Yu and Wang Pengyu take off from the ground aviation base, and before entering the predetermined range, they had already begun radio silence, using the stealth performance of the J-31 to stick to the J-15 around the corner, and then before approaching other aircraft, or flying close to the sea surface, or flying along a strange route, always slowly approaching the aircraft carrier.

Along the way, Xia Yu and Wang Pengyu always maintained a distance of more than 80 kilometers from the nearest ship or aircraft, except for the situation under the belly of the J-15, and the stealth performance of the J-31 was maximized. The airborne early warning aircraft, which poses the greatest threat to the J-31, has not been able to detect Xia Yu and the two because the two have always been 300 kilometers away from the early warning aircraft, and if they get closer, Xia Yu will not be able to guarantee that he will not be discovered.

Everyone in the mission briefing room watched the two J-31s soar and low, left and right, and strangely rush forward until they approached the aircraft carrier 120 kilometers before they were detected by radar. At this time, watching the video, I realized that the two J-31s opened the weapon hatch under the belly of the aircraft almost at the same time as they were discovered by the radar, put down the missile launcher, and then took it back, and the two J-31s completed a simulated attack.

After being silent for a while, Mu Shaoqing, as the flight commander, patted the two J-31s that were fixed on the screen with his hand and said: "This is a perfect sports raid battle, to be honest, although there is almost no possibility of replication, our aircraft carrier battle group does have loopholes that can be exploited when marching in formation." ”

When the video is closed, a 3D space model opens on the screen. In the model, the flight path of the J-31 is marked with a green line, and the flight paths of all ships and aircraft in the aircraft carrier battle group are also marked, pressing the play button, Mu Shaoqing pointed to the various ships and planes that began to move slowly and said: "When our ships and planes are moving, due to the deviation of speed and position, there are almost fleeting loopholes. ”

He pointed to one of the early warning helicopters and one or two J-15s, and under these two J-15s were Xia Yu and them. Mu Shaoqing rowed along the flight path of the helicopter and the J-15, and said: "The J-15 is staggered head-on above the early warning helicopter, and the J-31 should be found in this way, but Xia Yu They began to leave the J-15 80 kilometers away from the early warning helicopter, and turned left to fly close to the sea, at this time it was 420 kilometers away from our air early warning aircraft and 180 kilometers away from the nearest ship, successfully avoiding all radars." ”

"If it's just like this, it is impossible for the two J-31s to continue to approach the aircraft carrier, and the problem arises here." Mu Shaoqing said in a deep voice: "Xia Yu, while flying left to the sea to avoid the radar, they moved in the opposite direction to our air early warning aircraft, using the stealth performance of the aircraft to maintain a safe area of 80 kilometers from any aircraft and ships, and went around our defense area. ”

"In the end, it was only at a distance of 120 km from the aircraft carrier that it was detected by our radar. But everyone has seen that two J-31s have completed a simulated attack. Mu Shaoqing shook his head and said, "Although this flight was very accidental and lucky, it also shows that our defense circle is not mature, at least not as efficient as we expected." Our radar warning area also needs to be improved, and there must be some defensive arrangements for stealth fighters. In addition, I would like to give Comrades Xia Yu and Wang Pengyu a commendation for allowing us to discover such a serious problem in this exercise. At the very least, I'm glad that this is just a drill, not a possible encounter with the enemy someday. ”

Xia Yu didn't know that the results of the last exercise made the senior leaders still have a headache about how to improve and enhance the defense and vigilance capabilities of the aircraft carrier battle group, and his only feeling was that the water in his stomach was too uncomfortable, which made him still feel itchy in his throat when he thought about it today.

The flight test of the 31009 demonstrator has been basically completed today, and all aspects of the system have been rigorously tested, and as long as it returns to the factory for final testing in two days, it can be finalized and produced. Being able to personally participate in the development process of a new fighter is a great gain for Xia Yu, much greater than others imagined, because there is a starry sky.

In the long-term contact with the J-31 for nearly a year, even some of the improvement suggestions were put forward by Xia Yu, plus with the help of the starry sky, Xia Yu's understanding of the J-31 is not weaker than anyone else, including the chief designer of the aircraft and his design team. It can be said that as long as he provides materials and lets Xia Yu make another J-31 by himself, he will have no problem. Coupled with the depth of knowledge of the J-31, I am afraid that no one can compare to him on how to tap the flight potential of the J-31.

Tomorrow is the day when J-31 leaves the Liaoning and returns to the factory, and it is also the last time Xia Yu pilots J-31 in a short period of time, not necessarily, looking at the diamond-shaped fuselage of J-31 with some nostalgia, and wiping the number of 31009 under the cockpit with his hand, Xia Yu does not know that soon, this fourth-generation stealth fighter, which is still a verification model, will usher in its first real battle.
