On a rainy night, you can't see the starlight when you look up, and you can't see the ground when you look down.

After turning on the formation flight lights and converging Xue Fei and a few people, Yang Luo reported to the tower: "Tower, the sword squadron is preparing to carry out a low-altitude breakthrough, over." ”

In the Hengduan Mountain Range, the radar of the tower will lose its signal, and it is necessary to report to the tower before entering.

In the tower, Ye Jianlong was slightly nervous and said: "The tower has received, pay attention to safety, over." ”

After all, it was a low-altitude breakthrough at night, and it was a rainy day, and the visibility was at its lowest, and the danger was still quite high for high-speed flying fighters.

"Understood, over."

Yang Luo turned the pole and drilled into the valley with the sword squadron, and disappeared into the eyes of everyone at the station, and the radar of the tower also lost the trace of the four fighters at once.

In the most dangerous flight environment, low visibility is definitely at the forefront, and after so many years of modern science and technology, various products to solve such problems have emerged, among which terrain tracking radar is one of them.

Terrain tracking radar, also known as terrain following and terrain avoidance radar, is a radar on the aircraft that detects terrain changes and avoids obstacles.

The terrain following radar provides the detected undulating terrain information (distance, bearing, altitude) in front of the flight to the automatic flight control system or the pilot, so that the aircraft can be controlled to maintain a certain vertical distance from the ground.

The terrain avoidance radar constantly detects obstacles in front of the flight that are higher than the specified altitude, and the pilot makes lateral maneuvers according to the radar's instructions.

In order to fly safely at low altitudes, modern military aircraft can meet the requirements by only installing terrain following radar on board, and terrain avoidance radar is an auxiliary means.

Some airborne radars have both terrain following and terrain avoidance functions, and the active phased array radar on the 301 J-10C has both functions, so there is no additional terrain tracking radar.

At low altitude, Yang Luo prefers to believe in his eyes and fly visually, but this is a rainy night with extremely low visibility, and Yang Luo can only rely on radar.

After turning on the airborne active phased array radar, the distance, bearing, altitude and other information of the obstacles in front are presented on the radar screen, which is clear at a glance, but his own eyes can't see it, and Yang Luo always has a feeling of hair in his heart.

The previous night low-altitude penetration was basically carried out at night when there was a moon, and the visibility was okay, Yang Luo mainly relied on visual vision to fly, and the radar was only used as an auxiliary, because he was hairy in his heart, and he didn't dare to fully believe in the radar and instruments.

For the sake of safety, Yang Luo did not fly too low, maintaining an altitude of about 500 meters and a speed of about 500 kilometers per hour.

After this period of training, the other three were basically able to keep up with Yang Luo's footsteps in the field of low-altitude penetration, and at this time they maintained the same height and speed as Yang Luo.

The terrain tracking function of the active phased array radar is enhanced in detection range compared with the terrain tracking radar alone, but it can only continue to judge the terrain within 5 kilometers ahead, which actually leaves Yang Luo with less than a second of reaction time.

Therefore, they did not chat along the way, there was a dead silence in the communication channel, and they were all fully focused on controlling the plane.

"Boom!"

The roar of the unique aero engine of the Taihang-10C resounded in the valley, pulling the blue tail flame to rush left and right in the valley, often making a sharp turn to avoid the mountain ahead.

After walking through the valley for more than half an hour, a mountain with an altitude of 4,200 meters blocked the way, and this mountain was also Yang Luo's destination, and the target was a big rock at the highest point of the mountain.

"Attention to all aircraft, they have arrived at their destination and pulled up the climb height." Yang Luo reminded that the throttle valve was pushed to increase the supply of aviation fuel, the engine power was increased, the angle of attack was adjusted, and the pull rod lifted the nose of the aircraft and roared to climb in height.

"XXX received."

In the communication channel, the responses of three people were heard in turn, and almost simultaneously pulled the lever back and raised their heads, straight into the pitch-black sky overhead.

On the top of the mountain, a huge rock has stood quietly for an unknown number of years, and no one has paid attention to it, but this year it has been devastated and attacked by an unknown number of rockets.

This time, the ground target attack was also rockets, and each fighter mounted a 90mm rocket launcher on the belly of the aircraft, which contained seven guided rockets.

Low-altitude penetration, fire strike!

This is the standard ground offense.

The four J-10Cs climbed rapidly, and after just over twenty seconds, they had already climbed to the attack altitude.

The big stone target in the dark night, without any indication, can only be guessed by sight.

Yang Luo was naturally the first attack position, and after leveling up, he opened his eyes wide, staring at the vague mountain in front of him, looking for the big stone on its highest point.

After a short period of observation, combined with his own position at this time, Yang Luo roughly determined the location of the big stone.

The pressure lever lowered his head and locked on to his determined position through the on-board active phased array radar and helmet sight, and Yang Luo did not hesitate to press the weapon launch button at the top of the joystick.

Decisive, resolute.

"Whew! ……”

In an instant, 90-millimeter rockets were fired from the seven-barreled rocket launcher mounted in the belly of the aircraft, which shot out like arrows off the string, dragging a long tail flame in the rainy night, and pounced on the target along the predetermined trajectory.

"Boom!"

The first rocket exploded first, with shrapnel and a dazzling fire, like a beacon in the dark night.

Yang Luo didn't pull it up immediately, so at the moment of the explosion, he clearly saw that the rocket did not hit the big rock as a target, but fell about ten meters on its side.

The next six rockets fell one after the other and exploded, creating a brief sea of fire that was quickly extinguished by the rain.

Four of the six rockets in the back hit the target, and two also missed.

Even though it was devastated by four rockets, the boulder did not suffer much damage and remained unmoved.

With a total shooting percentage of only 57%, Yang Luo was very unhappy with the result, but it was the only way to do it.

Yang Luo pulled the lever away and gave up the position of the attack.

Immediately, the big stone was hit by three more waves of rockets, Xue Fei hit five, Xu Zhiqiang and Wang Hanyu both hit six.

Because of Yang Luo's first attack, the fire of the rocket explosion provided a good reference for them in the follow-up, so their results could be better than Yang Luo's.

In fact, in the daytime fixed ground target, the Sword squadron can almost achieve 100% hits.

After the attack ended, after Yang Luo contacted the tower, he commanded the sword squadron to turn around and turn back, and when he returned, he was still walking through the mountains, but he chose another route and gave way to the previous breakthrough route.

When Yang Luo and the others returned, Lu Younan had already taken off with three people to carry out low-altitude penetration and ground target training.

After returning to the station, Yang Luo went to the tower to command, replaced Ye Jianlong, and asked Ye Jianlong to take the remaining two pilots to participate in the training.

PS: I haven't been on the military classification monthly ticket list and recommendation list this month, so I have the cheekiness to ask for a ticket.

Ask for a monthly pass, ask for a subscription, ask for a referral ticket.
