Detailed topographic data, high-definition photos of the Pengcheng base, and even two J-10D and one J-10S taking off, this series of contents and various discoveries clearly show one content - the unknown enemy has basically mastered the situation of the Pengcheng base.

Serious losses in national defense and security interests!

The head of the air force, who got the news, slapped the table on the spot angrily, and the higher-level organizations and the western theater shook one after another, and the military security department immediately intervened in the incident and launched a detailed investigation in an attempt to find clues of an unknown enemy.

Of course, as for who is behind the scenes, I basically know in my heart.

In addition, there is one thing to be thankful about in this incident, that is, Zhou Hai and Su Peng accidentally discovered that the wild boar was carrying a miniature detection lens, which in turn let the military intelligence department know about this novel spy detection method combining cutting-edge technology and brain holes.

A real novelty, and it works!

As Zhou Hai thought before, who would have thought that a wild boar would carry such a thing as a miniature detection lens?

No one!

Completely touching the blind spot of knowledge is both reasonable and unexpected, and belongs to a model of innovation in espionage detection methods.

If it weren't for Zhou Hai and Su Peng's accidental discovery of this situation, the troops would still be in the dark, and they would not know that the J-10D 'Fire Dragon' fighter and the Pengcheng base were basically mastered by the enemy, and it was even possible that no one would ever know about it.

The discovery of the two - there is merit, and the credit is not small.

……

Time passed slowly, and it had been three days since the serious leak that shook the entire Pengcheng base.

The whole leak incident was not about the pilots at the base, and in addition to the tension, the daily flight training and work were carried out in an orderly manner.

The sky is blue, dotted with white clouds of different shapes, and the scorching sun hangs on the top of the sky, releasing endless light and heat.

It's still so hot.

Base camp area, aviator accommodation building.

Inside dormitory 112.

The Midea air conditioner on the wall is turned on, releasing a steady stream of cold air to keep the room cool.

"Try the first simulation, assuming that the interception at an altitude of 4,000 meters, the J-10D is equipped with a new 23 mm double-barreled cannon, the muzzle velocity of the shell is 720 meters per second, the effective firing range is 2000 meters, and the diameter of the probability error of the 1000-meter circle is 70 centimeters, which barely reaches the level of intercepting missiles, and the best interception point is 1440 meters."

Zhou Hai sat on the edge of the bed, nibbling on a fresh and bright red chilled watermelon, and his mind was still building a crucial interception model: "Changes in atmospheric air density, humidity, wind speed and air currents, the Thunderbolt-10 fourth-generation close-range combat missile, with X-shaped wing surface and vector propulsion technology, has a maximum flight speed of 1,360 meters per second, and an interception window of only 1.47 seconds." ”

After three full days, the rudimentary interception model, which had been barely constructed, is starting its first simulation operation.

In my mind, an extraordinary and special picture image has been presented.

The J-10D 'Fire Dragon', which adopts wing-body fusion and canard wing aerodynamic layout, is at an altitude of 4,000 meters, flying at a speed of thousands of kilometers per hour, and 10 kilometers in front of it, a sky-blue Thunderbolt-10 close-range combat missile is flying at a speed of 1,360 meters per second, and the distance between the two sides is crazy to shrink.

The J-10D 'Fire Dragon' flies at a speed of up to Mach 0.816, and the simulated Thunderbolt-10 close-range combat missile reaches a speed of Mach 4, with a relative movement speed of Mach 4.816 between the two, or 1,637 meters per second!

1 second!

2 seconds!

3 seconds!

After 4.88 seconds, the distance between the two sides is reduced to 2000 meters!

At this moment, the J-10D 'Fire Dragon' in the interception model immediately launched an attack, and the airborne 23-mm double-barreled cannon emitted clouds of thick white smoke, spitting out tongues of fire, and one after another extremely destructive deadly cone-shaped metal warheads shot out, moving at a speed of 720 meters per second, sweeping towards the Thunderbolt-10 missiles flying at high speed more than 1,000 meters in front of them.

A whole ten 23-mm armor-piercing shells, success or failure in one fell swoop.

Time passed for another second, and the imaginary interception explosion did not materialize.

The 23-mm armor-piercing projectile, which flew at high speed along the predetermined trajectory, was affected by the air and wind speed at an altitude of 4,000 meters, and the initial velocity was too low, and it passed by the Thunderbolt-10 and was not successfully intercepted.

The Thunderbolt-10, which flew at high speed, easily hit the simulated J-10D 'Fire Dragon', and the interception model failed to simulate operation for the first time!

"No, the flight speed of the 23-mm blunt-nosed cap-piercing shell is too slow, the wind direction and wind speed have a great impact on the trajectory of the projectile, and the shooting accuracy of the double-barreled cannon can only barely reach the standard, it is too difficult, no wonder there is only a 30% interception rate."

Zhou Hai finished eating the chilled watermelon, threw it into the trash, rubbed his slightly swollen forehead with his hand, and summed up the reasons for the failure of the first simulation operation: "This is only the best interception conditions and environment that exist in a small probability. ”

In modern air combat, only when the two planes fly head-on and lock on each other to launch medium-range bombs, can a frontal missile attack occur.

This is the optimal interception condition and environment.

The comprehensive performance of the 23-mm double-barreled cannon can meet the air combat and ground strafing in close combat without any problem, and if you want to intercept missiles flying at high speed, you can only barely meet the interception standard.

Aircraft artillery intercepts missiles, and the most important thing is aircraft artillery.

The muzzle velocity and firing accuracy of artillery shells are two key index parameters to measure the performance of aviation guns.

The J-10D is equipped with a 23-mm double-barreled cannon, with an initial velocity of 720 meters per second and a shooting accuracy of 70 centimeters on average at 1,000 meters.

"The performance of the aircraft gun is an objective factor, plus I am the first time to simulate, the next step is to increase the proficiency through repeated simulations, to see if the success rate can be improved, the interception model is also relatively simple, everything is slow."

Zhou Hai took a deep breath, he was not discouraged by the failure of the first simulation, after the tactical analysis and summary, he took a short rest, recovered the energy consumed, and prepared to start the second round of simulation.

It's normal to fail, and no one can succeed at the first time, unless it's as simple as an addition calculation of 1+1=2.

The rudimentary interception model, which is based on mathematics and knowledge of various disciplines, involves the movement process of missiles and fighter jets, all using dynamic data, and the amount of calculation is extremely large, even Zhou Hai is a little unable to hold on, and he needs to take a break for each simulation operation.

"Knock knock!"

At this moment, there was a sudden crisp knock on the door of the house.

Ask again?

Zhou Haiyu frowned slightly, a little puzzled, got up and walked to the dormitory door.

The serious leak incident had a wide impact, and during this time, in addition to normal flight training every day, Zhou Hai also had to be questioned about the army's intelligence department.

When I opened the door, I saw Su Peng, who was wearing a training uniform, standing outside the door, smiling, with joy in his eyes, and holding a blue folder in his right hand, not an unfamiliar military intelligence department personnel.
