Zhou Xiaodong's strategy of engaging the enemy is very clear, and he decided to implement Captain Long's combat ideas, if possible, it is still a priority to solve the fighters on the "Red Rock" side, and attacking ground targets is the second choice of luck.

As a pure air superiority fighter, the design of the J-10A itself, as well as the 1473 (KLJ-3) pulse Doppler radar on board, are not very suitable for air-to-side missions, and the opposite "Red Rock" seems to be the same.

However, compared with the "Chenlong" dispatched by the A-type aircraft, this time going north to the capital, "Hongyan" also brought two J-10B, the latter is a facelift of the former, and the multi-purpose capability has been further strengthened, and the equipped 1477 type AESA radar also has better downward scanning capabilities, at this point, it should be said that "Chenlong" is a bit of a loss, fortunately, the map is set to be a soft target with no defensive ability, and the attack power of the B type "Raptor" and the A type does not have much substantial difference. It mainly depends on the skill and luck of both players.

According to the commander's order, the two gray camouflage-painted J-10As soon separated far away, each stealthily engaged the enemy along a detour route, and Zhou Xiaodong's No. 03 continued to turn on the radar, and at the same time used the number chain to transmit the target number to the No. 04 plane, which was maintaining radio silence.

At first, he was not in a hurry to meet the enemy, and the radar tracking of Zhou Xiaodong's landline was relatively stable, but it was obvious that the "Hongyan" twin planes quickly detected the opponent's storage through the guòRWR, and the two orange triangles on the display screen quickly flashed and then disappeared, and when the radar captured it again, it became one. The distance is about seventy kilometers from the reading. This made Zhou Xiaodong a little vigilant. He tried to change the scanning method to determine whether the "one" target was a single "Raptor" or two enemy planes overlapping, but he could not come to a conclusion at once.

Judging from the local radar warning message, the No. 03 aircraft did not encounter the radar irradiation of the "Hongyan" aircraft, so did they turn on the radar, and if so, which part of the airspace they are concerned about?

In the multi-plane confrontation in the clear sky, the mission objective is not to blindly kill the enemy, and the situation is much more complicated than a simple air battle. Judging this matter with rich practical combat experience, Zhou Xiaodong pushed forward the throttle valve, appropriately increased speed, and remained vigilant, while flipping the switch and powering on the two PL-12 missiles, and at the same time using the number of chains to command the No. 04 aircraft to further reduce the altitude and change the course to 130.

At present, he is not sure what the intentions of the group of "Hongyan" twin planes that have just been discovered, if they are on a cruising mission and intended to protect ground targets, then it may be an opportunity for the "Chenlong".

In the sky, the No. 03 and No. 04 "Raptor" planes were in action, and the other group of gray fighters that entered the battlefield at low altitude were not idle.

On the field of aviation competition. The value of electronic countermeasures is often limited due to the rules of the competition. Because the aircraft and equipment systems of both sides are easy to know, if the two sides are allowed to turn on electronic interference, the competition will often become a kind of unskilled power competition, let alone spectacle, so important events such as IFT will restrict the use of electronic countermeasures in order to create a more conducive to the performance of the players in a "clean" environment.

With this limitation, the significance of keeping the radar silent on the field is even more obvious, because the fighter cannot use multiple electronic countermeasures to interfere with the opponent's RWR detection, and the electromagnetic detection system of the competition aircraft is extremely sensitive, and to ensure that the opponent does not notice, the radar shutdown is a completely necessary option.

Just like now, unlike the way of action of high-altitude teammates, the strategy of the 01 and 02 J-10A is a bit like "fishing", Long Yun's No. 01 plane jumped after flying over the border of the battle airspace, reaching an altitude of 3,000 meters, and the No. 02 plane carrying four "Thunderstone-6-100" flew further close to the ground, and the altitude soon dropped to less than 100 meters.

The so-called "art master is bold", what Long Yun is doing is to take the initiative to lure the enemy, if the opponent really pierces the enemy, he can try to delay and attract more attention from the "Hongyan" side.

Of course, if the timing is right, it would be better to shoot down one or two planes in the air, and if the situation really becomes like this, then the other fighters of the "Chenlong" can unscrupulously turn on the radar and search for targets everywhere, and after finding the right position, a few "Thunderstone-6" can be thrown out to lay the victory.

Since it is a soft target, it means that there is no air defense ability, and it is difficult for fighters to intercept GPS-guided bombs gliding and falling, and it is even more impossible to intercept multiple at the same time, so the winner of this contest is actually very simple, who can find the target first, enter the attack, and the moment the bomb leaves the pylon, it is equivalent to the end of the game.

Considering the results of the previous three single challenges, if "Hongyan" gets five points, it will win directly, and if "Chenlong" gets these five points, it will be the same result - isn't it, even if the opponent knocks down the four J-10A of "Chenlong", it is only four points, and this situation is destined to be impossible, because if the four fighters have been shot down, how can you talk about throwing bombs at the target?

Therefore, once the air-to-face attack is launched, the game will be over, and this is the basis for the system's decision.

Based on such considerations, the main goal is to solve the "Hongyan" fighters first, and several J-10A of the "Chenlong" did not ignore the search for ground targets.

But to be honest, although it is very likely to win directly if you find the target, it is still very difficult for Long Yun and others to complete this goal, the 1473 type PD radar on the J-10A is a mechanical scanning, using a flat panel slit array antenna with a diameter of 700 mm +, the design is biased towards the air, and the ground capability is not excellent, and the radar scanning speed, aperture power product and signal processing process are not fully suitable for searching ground targets.

According to the map setting, the signal repeater placed in the battle area and used as a target has a typical electromagnetic radiation characteristic equivalent to one square meter; In the case of Doppler filtering downward view mode and PRF optimum, the 1473 can only find a ground target of one square meter of RCS with known echo characteristics at a distance of only about 20 kilometers.

Out of such a consideration, neither of the two opposing teams now regards attacking ground targets as the first choice, and as for the "Chenlong", they have not specifically assigned fighters to protect their own ground targets, on the one hand, they intend to take the initiative to attack, and on the other hand, they do not want to expose the general location of the target because the fighters are cruising.

The two groups of twin planes acted separately, and the low-altitude swaggering Long Yun had not yet attracted an opponent, and the high-altitude sneak attack and anti-sneak attack contest had broken out, and the sneaking No. 04 "Raptor" quickly visually discovered the enemy plane.

After the sortie, it has been according to the number of Zhou Xiaodong's landline action, plus several J-10s of the "Red Rock" did not turn on the radar much, the two sides in the vast sky of hide and seek soon had results, the young man who drove the plane to reduce the altitude and swept the clear sky with both eyes suddenly found a black shadow in the direction of ten o'clock, and judged that it was not a teammate by virtue of the navigation information, he immediately called the long plane Zhou Xiaodong, but at the same time did not rush to pursue, but cautiously pulled the throttle valve and adjusted the course to keep watching.

Seeing the opponent with the naked eye in the air, generally speaking, this means that the opponent also sees himself, but now the J-10A of Bian Chao is in the backlight direction, and the visual observation conditions are a little better than that of the opponent, and the four "Thunder Stone-6" mounted on the landline have not yet come in handy, and Bian Chao is not in a hurry to pursue the target.

Losing in the one-on-one battle in the morning, as if nothing had happened on the surface, Bian Chao was still a little affected in his heart, and his actions were a little conservative.

I don't know the opponent's intentions, Bian Chao chose to wait and see, but Zhou Xiaodong, who received the wingman number on the chain, didn't see it that way, he was flying along a winding track to the north, which intermittently captured the traces of the "Red Rock" fighters, but he was never able to intercept and launch over-the-horizon missiles steadily, and his experience in the face of the enemy made him quickly judge that this group of "Raptor" fighters, no matter what the tactical intentions were at the beginning, are now playing hide and seek with him and Bian Chao, why did they do this?

Unlike the radar silent Bian Chao, the No. 03 J-10A, which has been searching for radar, Zhou Xiaodong does not believe that the opponent has not located his approximate location, and the "Raptor" who is about to leave the sky is probably trying to lure the enemy, so he immediately made a guess, determining that there are no ground targets that need to be protected around the two "Hongyan" fighters, and at the same time, he also launched this speculation on the two J-10A cruising at low altitude with the help of several chains.

Zhou Xiaodong's judgment is not sufficient evidence at all, but it is not far from the real situation of "Hongyan" now.

In the face of an opponent like "Chenlong", the "Hongyan" team members, including the captain Sun Zhe, did not underestimate the enemy at all, and still implemented the tactical plan formulated by Captain Sun before the game - with two J-10A cruising in the middle of the altitude and posing as a search for targets, and the other two J-10Bs had other arrangements, using such a defensive counterattack-like arrangement to meet the opponent.

When drawing lots, a map with gentle terrain was chosen, and each task was to destroy the target point, and "Red Rock" and "Chenlong" coincidentally chose the first place in air combat, which was actually for the same consideration.

Fighters search for ground targets, as mentioned earlier, the detection distance and accuracy are not high at all, especially the full-time air defense interceptor - J-10A/B, its own multi-purpose ability is limited, the fire control system, supporting ammunition is not strong enough, the four fighters of the "Red Rock" are more mounted, each aircraft carries four "Leishi-6-100", it seems that the firepower is quite fierce, in fact, if you can't find the target, it is all in vain.
