Chapter 807

The missile pushed into the tunnel slides all the way to the depth of the tunnel under the push of the flat car.

Although it is a missile, because the tunnel is not a complete branch line, it still needs a flat car to send the missile to a suitable position. It can't ignite directly at the tunnel entrance.

However, the military made preparations in advance when designing the tunnel. The tunnel is more than 4000 meters long and the vertical depth reaches 1500 meters. Although the last section has not been completely completed, it has also met the initial design requirements and can ensure the use of nuclear bombs.

As for that, the military asked Chen Xin to transform the missile in order to penetrate the last layer more than 100 meters deep, so as to directly detonate the nuclear warhead in the nest of alien organisms.

Although it sounds strange to launch missiles in the tunnel, it is not impossible to fire missiles in the tunnel as long as the tunnel is straight enough and long enough to maintain stability after the missile is ignited.

Although it is as dangerous as driving an aircraft through a tunnel, any change and jitter of air flow may make the missile deviate from the predetermined trajectory and hit the tunnel wall, but it is still feasible after all.

The ground penetrating missile, which has been upgraded and transformed by Chen Xinzhi, has been specially optimized in this regard to ensure that the missile can smoothly reach the bottom of the tunnel, penetrate more than 100 meters deep, and send the warhead carrying the nuclear bomb into the nest of alien organisms.

The speed of the flat car is accelerating. Although no one drives, through remote control, this modified flat car has gradually approached its speed limit.

"Ignition of booster rocket!" in the remote control room on the other side, I saw that the flat car had reached the predetermined depth, and the booster rocket installed on the flat car to accelerate began to work, further improving the speed of the flat car.

At the moment, the people in the remote control room are very nervous. They have done this for the first time. They have not done any exercises before. Everything is only a scheme obtained through computer simulation. At most, they have only run several simulation tests in the virtual system of Chen Xin.

Practice, this is the first time.

However, the first practice was actual combat.

Therefore, no one can guarantee that this time will be successful.

But similarly, everyone knows that this missile launch is not allowed to fail.

The reason is also very simple. What they shoot out is not an ordinary missile, but a strategic nuclear missile of the equivalent level of one million tons. Once the explosion position deviates, they can't complete the scheduled task. It's small, and other effects can't be borne by anyone.

However, with Chen Xin's upgrading and adjustment of the missile, the whole launch process has also undergone several simulation tests. In theory, there will be no problem.

Just when everyone was sweating, the staff responsible for broadcasting the situation suddenly shouted, "the missile is about to enter the horizontal section!"

"Separation of the first stage booster rocket!" the person in charge of the launch also issued his own order loudly.

This order was accurately executed. While the missile entered the horizontal section, the first stage booster rocket that had completed the acceleration was separated from the flat car very smoothly, and at the same time, the second stage accelerator rocket was ignited smoothly.

According to the predetermined plan, the first stage rocket boost allows the flat car carrying the missile to pass through the first inclined downward tunnel. After entering the horizontal section, it carries out the second stage acceleration. After leaving the horizontal section, the missile itself will start ignition, and then go all the way down to the bottom of the tunnel.

The main reason for this arrangement is that no one has fired a missile in the underground tunnel. There is also a horizontal section of the tunnel that is planned to be expanded into a logistics base in order to enable the troops to better put into operation. Naturally, it can't directly let the missile ignite and fly by itself.

However, when the missile leaves the horizontal section, the missile itself will separate from the flat car after ignition, further increasing the speed.

This is also to improve the speed of the missile as much as possible. After all, in the tunnel, due to the influence of all aspects, it is impossible for the speed of the missile to break through the sound barrier. Therefore, in order to improve the speed of the missile as much as possible, we can only improve the speed of the missile as much as possible through multi-stage rocket acceleration.

The engine of the missile itself has been adjusted. Although it will not accelerate the speed of the missile to break through the sound speed, it will also make the speed of the missile close to the sound speed as much as possible to provide more kinetic energy.

As for how a missile that does not reach the speed of sound will penetrate the stratum more than 100 meters later, this is what Chen Xin's transformation needs to achieve.

In fact, the principle of the ground penetrating warhead of the missile is similar to that of the shell piercing projectile. The outer shell is made of soft material. After hitting the target, the inner shell made of hard material wrapped in the outer shell penetrates the armor or stratum with strong kinetic energy.

However, Chen Xin adopted some brain hole designs on the missile. When the missile hits the target, the hard armor piercing warhead with a nuclear bomb inside will be hit out like a shell in the gun chamber, so that its speed can break through the sound speed and obtain enough kinetic energy to penetrate more than 100 meters of the formation.

Of course, this design is not available on serious missiles. It is entirely Chen Xin's idea of relying on his brain hole, and then forcibly upgraded it with the system upgrade function.

After all, no missile will consider launching in a tunnel, let alone how to make a nuclear warhead penetrate more than 100 meters deep and detonate more than 1500 meters underground.

As for why we should accelerate the missile after Chen Xin's upgrading and transformation can penetrate a warhead more than 100 meters deep, it is in order to enable the missile body to penetrate the pile of corpses dozens of meters long deposited at the bottom of the tunnel.

Of course, these corpses are not as hard as the stratum, but the gap between a large number of corpses and the softness of the corpse itself are excellent cushioning materials. If the missile can not accelerate to a certain extent and forcibly penetrate these corpses, the missile will get stuck in these corpses.

In this way, even if Chen Xin's upgraded warhead can penetrate the formation, it will also be affected, lose a lot of kinetic energy, and may even fail to penetrate the formation.

With the support of these measures, the missile finally plunged into the bodies at the bottom of the tunnel, penetrated the layers of bodies with strong thrust and reached the bottom of the tunnel.

"Bang!" a steel needle like ground penetrating warhead, which is much thinner than the missile, shoots out from the top of the missile and instantly penetrates into the stratum.

Then... The people in the remote command room felt the earth shaking under their feet.
