This time, it's the damage in the atmosphere.

The object of the test was a specially modified GJ-21 "Meteor" jet.

This Meteor aircraft has undergone a deep transformation, completely using unmanned flights, removing everything that can be discarded, and only filling half of the fuel volume, reducing the weight by about 20%.

The back of its body is covered with an ablative material about 3 x 3 meters in size, which is grayish-black, which is the target that Qianjun Stick 1 is ready to irradiate.

The GJ-21 will reach Mach 2.1 for about 20 seconds with a small dive after reaching an altitude of 21,500 meters.

In the nearby air traffic control eyes, an unmanned meteor training plane that had been reported in advance for the purpose of testing a new type of improved engine took off in the base.

The Air Force's radar operator checked the number, confirmed that it was correct, and set it aside, and this unmanned test flight flew at a high altitude and would not interfere with other aircraft.

The unmanned Meteor Jet, internally codenamed 2231, means the 31st production model of the second batch, and it is beginning to circle under the control of the ground.

Lin Ju nervously looked at the staggered route displayed on the screen in the secret center, which showed that Qianjun Stick No. 1 would take another 2 minutes to reach the area where the attack could be launched.

Three low-orbit communications satellites and a geostationary-orbit "Gaoshan" platform send signals to the base at frequencies beyond normal communication, while providing auxiliary calibration for Qianjunbang-1.

In order to simulate the real situation, the No. 2231 jet turned off satellite navigation, and Qianjun Bang-1 had to rely on low-orbit satellite detection to locate it, and then activate its own comprehensive and precise positioning means including optical, infrared, and electromagnetic waves.

The area where SCP-2231 hovers above the base is a tiny slot for the Qianjun Stick One at an altitude of 270 km, and the attack window is only 2 minutes in total, and the full power attack needs to be cooled down for 150 seconds each time, so there is only one chance.

Lin Ju looked at the sky from the bunker window, this is a rare good time to be cloudless, and the attack effect should be ideal.

When the Qianjun Stick 1 was about to enter the attack window, the operator of Jet 2231 was ordered to put the engine into an overload afterburner, providing more than 16 tons of thrust at the cost of life, and the engine rotor speed was overloaded by a full 35%.

The speed of the jet immediately increased rapidly, and the altitude rose all the way to 21,000 meters, and then the final acceleration was carried out in an irregular course with a small depression angle, depending on the setting.

Nearby radar stations immediately noticed the conspicuous high-altitude high speed of 2231, but they didn't think much of it, and they couldn't see it anyway.

But in the secret control center of Qianjun Bang No. 1, more than a dozen engineers were nervous and paid close attention to the status of Qianjun Bang No. 1.

The cost of nearly 3 billion yuan and more research and development costs were not wasted, and in the 17th second after entering the attack window, the Qianjun Stick No. 1 spaceborne computer automatically searched for and locked 2231.

"Target-locked, fine-tuning aiming in progress!"

At an altitude of 270,000 meters above the continuously accelerating Meteor High Education Aircraft, the RCS of Qianjunbang-1 carefully worked for a few seconds under the control of SC09, and the cylindrical satellite moved imperceptibly at a slight angle.

Four other small lasers for calibration attempt to illuminate the ablative thermal insulation paint in the middle of the 2231 body, which is intended for re-entry objects, and is very resistant to high temperatures and friction.

The reflected laser light will vary depending on the shape and material of the irradiated part, and this slight difference is the basis for the deflection of the prism inside the gyroscope and the 11 laser lenses under electromagnetic action.

At 55 seconds after entering the attack window, the light returned by the on-board computer sensory calibration laser was stable and consistent with the characteristics of the ablative paint.

"Calibration, attack!"

The staff on the ground just read out the status, in fact, except for the selection of attack targets, everything else is controlled by computers, otherwise it is simply too late.

Lin Ju and Zhao Xiaowen's hearts are tight, with an investment of more than 5 billion yuan, it depends on this time.

In the bright afternoon sun, a laser beam spanning 270 kilometers passed through the thick atmosphere, and the energy was attenuated by nearly 30% after being blocked by many obstacles, and diverged as the distance increased, and finally became a pillar of light with a diameter of about 3 meters when observed on the ground.

The moment the seven 140-kilowatt gas lasers of Qianjun Rod-1 were excited, the irregular paint surface on the back of the Meteor Jet, which had reached Mach 2.13, was covered by the light spots of the prototype.

Under the energy transfer of high-frequency photons, the temperature of the paint rises rapidly, and the material originally designed to combat atmospheric friction at Mach 20 begins to melt and disappear layer by layer with the high-speed air flow in the opposite direction.

In the control center, the temperature sensor on the surface of the 2231 body still did not see any abnormality, and at this time, the irradiation time transmitted back by Qianjun Stick No. 1 had reached the 19th second, and half of the maximum 40 seconds of follow-up irradiation time had passed.

20 seconds, 21 seconds, 22 seconds...... 33 seconds!

The value of the temperature sensor placed under the ablative paint on the back of the machine and on the surface of the body suddenly jumped from more than 100 degrees, almost instantly to four digits, and before it had time to see clearly, it became "E-".

Zhao Xiaowen immediately looked at the radar that had been tracking 2231, and the radar reflection projection on it really began to change.

When all the ablative paint covering the back of the machine is lost, the body is exposed to more than 680 kilowatts of laser, and the skin is immediately twisted and deformed at high temperatures, and the air flow of more than twice the speed of sound rolls up the softened skin and flies away, and the fragile internal structure is also exposed to air and light spots.

The position of the ablative paint is the center of the fuselage, and when it also begins to deform, the pressure on the front of the aircraft begins to compress and bend the fuselage, and the automatic flight control tries to adjust the rudder surface to save the aircraft, but the aircraft has begun to break back irrepressibly.

It took only 7 seconds from the 29th second to burn through the ablative material to the irregular shape of the radar area of 2231, and at the 40th second, Qianjun Stick No. 1 lost its attack target and automatically turned off the laser.

The high-altitude education plane flying at twice the speed of sound had broken, collided, torn apart, and became a pile of wreckage of different sizes and began to spin and fall, and the calibration laser could no longer search for the first signal.

Qianjunbang-1 and several low-orbit satellites that worked for it did a cursory search of the surrounding area of 50x50 kilometers, but found no similar signals to the target, determined that the target had been destroyed, and sent a "message that the attack has been completed and the target has been destroyed" to the ground.

From the moment Qianjun Stick No. 1 entered the attack window, it took a total of 95 seconds to complete the entire process of searching, locking, attacking, and destroying the target, of which it took only 40 seconds to ablate to complete destruction, and 33 seconds to burn ablative material that was enough to cope with the high temperature of atmospheric friction.

There is no doubt that even if it is only a verification machine, Qianjun Stick 1 has the ability to be put into practical use.
