As an air base on the sea, an aircraft carrier itself does not have any protection capability, and it is not too much to compare an aircraft carrier that sails alone to a huge steel coffin at sea. Therefore, in order to form combat effectiveness, the most basic defensive measures are extremely necessary, so there is an all-round three-dimensional defensive warning area.

In the sky, there are early warning aircraft, early warning helicopters, and on the surface, there are destroyers, cruisers, anti-submarine ships, and other protective ship groups, and underwater, there must be at least two submarines protecting them.

As China's first aircraft carrier, the Liaoning's main purpose is to use it as a training ship, so all the equipment has been basically completed or even slightly exceeded, and the training has never stopped in the past few years since it was launched, and although it has gained a lot of experience, there are still many deficiencies, and it will take at least two or three years to form a basic combat effectiveness.

As the commander-in-chief of the Liaoning, Rear Admiral Chen Guofang actually knew very well where the gap was, so he always seized the time to do all kinds of training he could think of, hoping to find out and solve problems.

As a verification model, the J-31 let him know that the J-15 carrier-based aircraft had been beaten all over the place, but he did not get angry, but felt that this was a good opportunity to test the defense capability of the aircraft carrier battle group, after all, since the launch of the Liaoning, there has been no air defense drill for stealth fighters. After asking Wang Yifu and confirming that the J-31 was able to participate in such training, Chen Guofang asked for an air defense exercise against air strikes by stealth fighters.

Xia Yu did not refuse this kind of training, and this is also a good opportunity to test whether the J-31 has the ability to cross the blockade line of the aircraft carrier battle group, although the opportunity is not large, but it can be tried.

The alert range of an aircraft carrier battle group is about 1,000 kilometers, and it can be extended a little if necessary. Since there was no second aircraft carrier for the J-31 to take off and land, it was first moved away from the aircraft carrier, then refueled from the tanker, and then began to conduct raid drills.

In the expectation of Major General Chen Guofang, under the condition that the air early warning aircraft, surface early warning ships, early warning helicopters patrolling around, and the high-power radar of the aircraft carrier itself have a three-dimensional multiple alert effect, even if the J-31 is a stealth fighter, it will definitely be discovered when it is close to the aircraft carrier at most 500 kilometers, as long as the air defense system is activated at the same time as the discovery, and the carrier-based aircraft is urgently lifted into the air, even if the stealth fighter cannot be knocked down, at least it can drive the other party away. But the final result was beyond his expectations, Xia Yu and Wang Pengyu kept approaching the aircraft carrier until they were more than 120 kilometers away before they were discovered.

120 km, that's the distance at which a missile can be launched directly.

Rear Admiral Chen Guofang was furious and yelled at everyone in the command bridge: "Bastards, you bastards! If this is a real battle, we will lose our ability to fight, if not sunk! And what about our frigate group? And what about our AWACS? And what about our carrier-based aircraft? What are you all doing? Sleepwalking?! ”

When Chen Guofang, who was furious in the face of his subordinates, turned his head to Wang Yifu, there was no anger on his face, and although his expression was calm, Wang Yifu could find a trace of worry in his sharp eyes.

"Lao Wang, the problems found in this exercise are too important. The J-11, which can be found one-on-one at a distance of 50 kilometers, actually broke into the warning range of 1,000 kilometers of our aircraft carrier battle group, and was not discovered until 120 kilometers. ”

Wang Yifu smiled bitterly and shook his head, to be honest, he himself was surprised, he really didn't know much about the technical parameters of the J-31, and it was almost impossible to achieve such results, but Xia Yu and they did it. Looking at Chen Guofang with a heavy face, Wang Yifu said: "I don't know, when Xia Yu and the others come back, I will ask them how they did it, and I will know what is going on after the technical department extracts the flight data."

"Well, you have to do your best." Chen Guofang sighed heavily.

landed accurately on the flight deck, and as soon as he got off the plane, he found that the ground staff looked at him with bitterness and hatred, Xia Yu was stunned for a moment, he didn't seem to have offended them, right?

The older Wang Pengyu has a much better understanding of human affairs than Xia Yu, patted Xia Yu on the shoulder and said, "You bombed other people's aircraft carriers just now, so it's normal for people to give you a little look."

Xia Yu was speechless, this is not really blown up, and it is not enough to blame himself. They should be thankful for themselves, otherwise what if they encounter a real battle in the future, and the enemy will attack like this? Only by finding a problem can you solve it, Xia Yu slandered.

As soon as they stepped out of the inner cabin, they found that the supreme commander of the aircraft carrier, Major Admiral Chen Guofang, was waiting for them in line with a large number of black-faced senior leaders.

It won't be settled after the autumn, right? Xia Yu was thinking about it, when he saw Major General Chen Guofang coming up, and the two of them stood up and saluted: "Hello chief!"

After returning the salute, Chen Guofang waved his hand and said, "You're welcome, you have taught us a good lesson today." I'm here to ask you how you got so close to being discovered, and I don't know why, I can't sleep at night. ”

"Report to the chief." Xia Yu was about to salute again, Chen Guofang hurriedly waved his hand to him not to be too polite, and then Xia Yu said: "We are flying stealth fighters, usually we can ensure that we are not detected by the opponent's radar while discovering the enemy, so that we can avoid the detection area of the opponent's radar, and have time to shift the direction to attack or detour, and this is how we bypassed."

"Just get around?" Chen Guofang was not satisfied with Xia Yu's answer, and said with a frown: "The alert space of my aircraft carrier battle group is three-dimensional, even if you change your position and are not discovered by patrol and reconnaissance planes, I still have naval radars and early warning planes in the air, you can't get to such a close distance so easily, Comrade Xia Yu, let's talk more about it."

"Yes, Chief." Xia Yu said: "We avoid the radar strafing of the patrol and reconnaissance aircraft, and use the stealth characteristics to go around behind the patrol and reconnaissance fuselage at a distance that may be detected, so that the patrol and reconnaissance aircraft cannot detect us, and then stick under its fuselage, and follow the patrol and reconnaissance aircraft while flying, we use passive radar to determine the position of the surrounding ships, from which we can find a forward route." Although we have successfully penetrated to within 120 kilometers of the aircraft carrier, there is a certain element of chance and luck in our actions, and it is unknown whether we will succeed next time. ”

"Sticking under the patrol reconnaissance fuselage?" Chen Guofang's eyes widened, he looked at Xia Yu in disbelief, and then turned his head to Mu Shaoqing is question all the time: "The other party is stuck under our plane like this, but it is not discovered?" Still being taken into the depths of my defensive circle? Xiao Mu, how did you do it, how could this situation have happened? ”
