Doomsday Bunker Upgrade

The missile that was pushed into the tunnel slid all the way toward the depths of the tunnel under the push of the flatbed truck.

Although it is a missile, because the tunnel is not a complete branch line, a flatbed truck is still needed to send the missile to a suitable location, and it cannot be ignited directly at the tunnel entrance.

However, the military made preparations in advance when designing the tunnel. The tunnel with a length of more than 4,000 meters has a vertical depth of 1,500 meters. Although the last section has not been completely completed, it has already met the initial design requirements. The use of nuclear bombs can be guaranteed.

As for the military looking for Chen Xin to modify the missile, in order to penetrate the last more than one hundred meters deep, in order to achieve the purpose of directly detonating the nuclear warhead in the nest of alien creatures.

Although launching a missile in a tunnel sounds incredible, as long as the tunnel is straight and long enough, the missile can remain stable after it is ignited. It is not impossible to let the missile ignite and launch in the tunnel.

Although this is as dangerous as driving an airplane through a tunnel, any change and jitter in the airflow may cause the missile to deviate from the predetermined trajectory and hit the tunnel wall and affect its hit, but it is still feasible after all.

This ground-penetrating missile, which has been upgraded and transformed by Chen Xinzhi’s hand, has been deliberately optimized in this regard to ensure that the missile can reach the bottom of the tunnel smoothly and penetrate the ground more than 100 meters deep. The warhead of the nuclear bomb is sent into the nest of alien creatures.

The speed of the flatbed truck is constantly accelerating. Although no one is driving it, through remote control, this modified flatbed truck has gradually approached its speed limit.

"Boost the rocket to ignite!" In the remote control room on the other side, watching the flatbed has reached the predetermined depth, the booster rocket installed on the flatbed for acceleration starts to work, further increasing the speed of the flatbed.

At this moment, the people in the remote control room are very nervous. They are doing this kind of thing for the first time. They have not done any exercises before. Everything is just a plan drawn by computer simulation, at most only on Chen Xin’s side. Several simulation tests have been run in the virtual system.

Actually, this is the first time.

However, this first actual operation was actual combat.

So no one dared to pack a ticket and say that this time it will be successful.

But again, everyone knows that no failure is allowed in this missile launch.

The reason is also very simple. What they fired is not an ordinary missile, but a strategic nuclear missile with a million-ton equivalent level. Once the explosion position is deviated, the scheduled task cannot be completed. It is small, causing other impacts. It is the responsibility that no one can bear.

However, with Chen Xin's upgrade and adjustment of the missile, the entire launch process has also undergone several simulation tests. In theory, there should be no problems.

When everyone was sweating, the staff in charge of reporting 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 this launch also issued his order loudly.

This command was accurately executed. When the missile entered the horizontal section, the first-stage booster rocket that had completed the acceleration work was separated from the flatbed very smoothly, and at the same time, the second-stage acceleration rocket It also ignites smoothly.

According to the predetermined plan, the first-stage rocket assisted the flatbed vehicle with the missile to pass through the first section of the tunnel obliquely downward. After entering the horizontal section, the second-stage acceleration was carried out. After leaving the horizontal section, the missile itself would start. Ignite, and then all the way down to the bottom of the tunnel.

The main reason for this arrangement is that no one has ever fired missiles in an underground tunnel. There is also a section of the tunnel in the tunnel to allow troops to be better engaged in combat. It is planned to expand into a logistics base and build a horizontal section of the road. Naturally, it is not possible. Let the missile ignite and fly by itself.

However, when the missile leaves the horizontal section, the missile itself will be separated from the flatbed vehicle after ignition, further increasing the speed.

This is also to increase the speed of the missile as much as possible. After all, due to various influences in the tunnel, it is impossible for the speed of the missile to break through the sound barrier. Therefore, in order to increase the speed of the missile as much as possible, it can only pass through Multi-stage rocket acceleration is used to increase the speed of the missile as much as possible.

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

As for how a missile that has not reached the speed of sound penetrates the ground more than 100 meters later, this is what Chen Xin needs to achieve in his transformation.

In fact, the principle of the missile’s ground penetrating warhead is similar to that of the armor-piercing projectile. The outer shell is made of softer materials. After hitting the target, the inner shell made of hard materials is wrapped in the outer shell. The warhead uses powerful kinetic energy to penetrate armor or ground.

It’s just that Chen Xin adopted some brain-inspired designs on this missile. When the missile hits the target, the hard armor-piercing warhead carrying the nuclear bomb inside it will be shot out like a shell in the barrel, so that it can be destroyed. The speed breaks through the speed of sound, gaining enough kinetic energy to penetrate more than one hundred meters of ground.

Of course, this kind of design is not something that would happen on a serious missile, it was entirely based on Chen Xin's brain-inspired ideas, and then forcibly upgraded it with the system upgrade function.

After all, no missile would consider launching in a tunnel. uukanshu.com will not even consider how to make a nuclear warhead penetrate the ground more than 100 meters deep and detonate it at a depth of more than 1,500 meters.

As for why it is necessary to accelerate the missile after the warhead that can penetrate more than 100 meters deep after the upgrade and transformation of Chen Xin, it is to allow the missile body to penetrate the pile of siltation at the bottom of the tunnel. A corpse ten meters in length.

Of course, these corpses are not as hard as the stratum, but the large number of gaps between the corpses and the softness of the corpses themselves are excellent cushioning materials. If the missiles cannot be accelerated to a certain extent and forced to penetrate these corpses, it will let them The missile got stuck in these corpses.

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

With the guarantee of these measures, the missile finally plunged headlong into the corpse at the bottom of the tunnel, and with strong thrust, it penetrated the layers of corpses and reached the bottom of the tunnel.

"Bang!" A ground-penetrating warhead like a steel needle much thinner than a missile shot out from the top of the missile and plunged into the ground in an instant.

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