Night, quietly.

Nightlife people heard a rumbling sound from far and near, and the roar overhead drowned out the world. The young people at the open-air barbecue stalls were holding their necks high to find the source of the sound, and saw the two brightest stars, red and green, flying by like meteors in the night sky, taking away the roar.

It's just another normal night, to drink and play, and it's no different from any time ever.

However, for Li Zhan and Chen Fei, who had just soared past at subsonic ultra-low altitude, this air-ground confrontation drill in the early hours of the morning was of great significance.

For the first time, it confronted the ground-to-air missile units along the southeast coast, carried out the "kicking the door" operation for the first time, and tried to break through the three-dimensional air defense network for the first time......

Of course, it is also the first time to fight against HNA's J-10 fleet, but if it fights them, it means that the operation has failed. However, as long as he thinks of HNA's J-10 fighter simulating the Blue Army's F-16A/B Brock 20, Li Zhan finds it funny. It seems that it really looks like that, they are all medium-sized single-engine fighters, they all started with air superiority and then developed into multi-purpose, and they all formed a family, basically needle-to-needle.

The two J-10As patrolling at high altitude pose little threat, and Li Zhan has a thousand ways to avoid their search, but the biggest threat is actually the "strong network" early radar warning system that the birdcage ground-to-air missile unit relies on.

This is the reason why Li Zhan had to descend hundreds of kilometers in advance to conduct an ultra-low-altitude flight, and to use the high-rise buildings of the urban agglomeration and the hilly and mountainous terrain in the southeast region as a cover to covertly and quickly approach the target.

A large number of troops were stationed in the series of areas they passed, including army units, air force units, and even naval shore defense units, and any air activity was temporarily halted to open a safe passage for them. For example, the army's artillery units often fire at night, and those large-caliber shells can pose a deadly threat to ultra-low-flying fighters.

Li Zhan stared at the horizon and frequently adjusted the flight attitude of the fighter plane with a combination of visual observation and instrument data to avoid obstacles above 300 meters above sea level. Many hilly and mountainous areas in the southeast are generally two or three hundred meters above sea level, which means that Li Zhan basically flew close to the mountain.

When crossing the city, he detoured as much as possible, and if he couldn't get around, he would pull it up slightly to avoid the possibility of flying machines such as drones at low altitudes in the city.

Occasionally, when a large overload avoidance maneuver, Chen Fei was caught off guard and always needed to hold the cockpit canopy with his hands to stabilize his sitting position, otherwise it would be difficult to fix people on the seat with the seat belt alone - even if he brought a helmet and knocked on the cockpit canopy, it would not be uncomfortable. The fighter will tremble violently during a large overload maneuver, and the vision will tremble with it, so a handrail is installed on the arched fixed frame at the upper end of the instrument panel, similar to the armrest above the door frame of an off-road vehicle.

A pilot's entire career is inseparable from three types of equipment: spiral ladder, live roll, and solid roll.

The purpose of these three types of equipment is to train the pilot's anti-dizziness and sense of balance. There is no fixed reference for the plane to fly in the air, and the direction of the person standing on the ground is fixed, no matter where you stand, but in the air these directions are based on the central axis of the aircraft, and will change with the change of the aircraft's attitude.

Regardless of the change in direction, there is plenty of time and space to correct the illusion even if there is a mistake in high-altitude flight, and the behavior of ultra-low-altitude flight is intimidating to many pilots precisely because the space for maneuver reaction is compressed to the extreme. There are many examples of how you think the plane is climbing but is actually diving into the ground, and there have been painful lessons in the history of civil aviation.

On December 22, 1999, a Boeing-747 all-cargo plane of Dahang Airlines Flight 8509 took off from Stansted Airport to Milan, and the plane crashed 55 seconds after takeoff, hitting a nine-meter-deep crater in the ground. The main reason was that the captain's horizon had a problem and did not show that the plane was tilting, and the captain was unable to make corresponding rescue actions until it crashed.

If you are driving on the ground, it is easy to sense that the vehicle is leaning, but in an aircraft flying at night, it is difficult for the pilot to detect that the aircraft is leaning from the senses. The plane was in a state of accelerated climbing, and in that case there was no time to save after the alarm sounded.

That's not the case with freighters, let alone faster fighters.

Therefore, Li Zhan was engrossed in manipulating the fighter plane, like a F1 driver, constantly drifting in and out of the corner, drifting and cutting the radius, avoiding one after another peaks with an altitude of hundreds of meters that were especially prominent in the hills.

When he was training, others ran 5 kilometers for 20 minutes, but Li Zhan ran for more than half an hour, because he ran alive. The fact that he can withstand the overload of eleven or twelve G's is not that his body structure is different from that of others, but that he works harder than others when training.

"Eight kilometers of coastline!" Chen Fei performed the duties of the second pilot, weapons operator, navigator, and communicator very well, and in short, when Li Zhan was focusing on flying, he was responsible for other work as a rear cabin pilot.

Li Zhan glanced at the location parameters, and quickly mentally calculated the direction and matched the chart in his mind, "Confirm, the coastline is eight kilometers!" ”

"Fu Zhi, Wuyi Mountain is ready to cross the coastline, over." Chen Fei reported to the Fuzhou command post.

The vast majority of the troops on duty at the Fuzhou command post were calling for this "night attack on the widow's village" air-ground confrontation exercise, and the commander on duty immediately replied: "Received, Wuyishan can be carried out as planned, over." ”

"Understood, according to plan!" Chen Fei replied.

Li Zhan slowed down slightly, approaching the coastline at an airspeed of 500 kilometers per hour, but he lowered his flight altitude again and called Fu Zhi, "Fu Zhi, are there large ships passing in the sea ahead?" I'm probably going to have to fly across the sea, done. ”

"Wuyi Mountain, the flight altitude shall not be less than fifty meters, over." The Fuzhou command post directly issued clear instructions.

Li Zhan felt quite helpless, but he didn't expect that the Air Force would also follow the HNA and set the minimum altitude for flying across the sea at night. In fact, if there were no such restriction, if he had made a breakthrough by flying at an ultra-low altitude to skim the sea like during the day, Li Zhan would have been confident that he would have entered the attack range before being caught by the "Qiangwang" early warning radar system.

"What to do? I'm afraid it's hard to get into attack range at this height. Li Zhan asked Chen Fei.

Chen Fei said very shamefully, "You can't help me, what can I do." The detection range of the strong network system for low-altitude targets is only a theoretical 100 kilometers, right? ”

"We can't leave anything to chance, there are air supremacy fighters and early warning planes at high altitudes, and there is a complete radar system on the ground, and their three-dimensional detection is very good." Li Zhan pondered.

The air division set up a small obstacle for them, and it depends on how the Li Zhan crew uses the advantages of the J-16 to overcome the difficulties.

"Let's attack the west, but in this case, we may not have enough aviation fuel to coordinate with the 300 divisions." Li Zhan said.

Chen Fei said, "That's not the content of the plan, first deal with this air-ground confrontation, so let's get into the 50-kilometer attack distance, can we complete the attack procedure." ”

"You're too pessimistic. Since you can't find a breakthrough, then create a breakthrough, look, I mobilize their air warning, and this will come out without a breakthrough. The air division didn't say that it couldn't change the battlefield background. Li Zhan said with a smile.

Their conversation could be heard at the Fuzhou command post, and several leaders on duty looked at each other - this is too bold, isn't it?
