Chapter 4037: Ground blasting

Although Crystal provided enough information, Lin Rui's intelligence team was not idle.
Since the accident with the CIA, Lin Rui has always had a requirement, that is, all intelligence must be carefully verified, and try not to rely on or rely on information from external sources as much as possible.
Vitalk's intelligence also confirmed the existence of the terrorist camp.
"It was a large base originally belonging to the West African branch of the Jihad League. They have been operating there for many years. Although the momentum is not as good as before, there are hundreds of people." Vitak nodded, "There is indeed news that a group of Chechens are here. They are there. But the details are unknown.
As for the underground facilities of that base, we have no time to ascertain. But judging from the map provided by Crystal, they are quite accurate in surveying and mapping, especially in some details, they handle quite well. So in my opinion, this map should be a survey of internal personnel of terrorist organizations, and it will not be fake. "
"In other words, there is no need to doubt the authenticity of the information. My opinion is that this information can be trusted. However, we still need to pay great attention to the details of the operation." Jiang An nodded.
Lin Rui was silent for a while and said, "In this case, we will proceed according to plan. Bring the map."
Vitalk handed the electronic map to Lin Rui.
Lin Rui looked at the map, "We set the attack point at this location, and the headquarters is 20 kilometers away from the enemy base. Crystal and her people will provide us with 4 Kestrel gunships, which are also placed in the headquarters. Around, used to cover our ground operations.
Our five teams on the ground are responsible for attacking from three directions and attracting firepower. The assault team is under my direct command, and will conduct directional blasting from this position. Exploding their tunnels directly, Oh entered their underground fortifications. Sausage, you are an expert in blasting, is there any difficulty in this regard? "
"I noticed that their underground fortification structure is quite simple, but the shallowest position is also 20 meters from the ground. And the location we chose to invade is here, 30 meters from the ground. With our existing blasting capabilities, I'm afraid It is difficult to blow through directly. Because their interior is reinforced with reinforced concrete, we need high-powered bombs." Sausage replied.
"Find a crystal for you, she can get any weapon." Lin Rui nodded.
"I'm afraid she won't be able to help with this task, unless she has great magical powers and can get a ground penetrating warhead. Another Tomahawk cruise missile, guided by joint GPS, has a payload of 450 kg and a charge of 50 cm in diameter. The projectile’s landing speed is 260-335 meters per second. MWS warheads must be used, which can drill through 6-9 meters of soil and then drill through 3.6-5.5 meters of concrete to detonate 23-70 kilograms of charge." Sausage shook his head. .
"Need a bomb?" Lin Rui frowned.
Ordinary bombs will explode as soon as they touch the ground, but the ground penetrating bomb has its own trick: when it hits the ground, it will not explode immediately, but will continue to drill down. When it reaches a certain depth, it explodes. Thus destroying the target deep underground. General ground penetrating bombs can penetrate concrete grounds hundreds of millimeters thick.
The reason why this kind of ground penetrating projectile can penetrate deep underground is achieved by its strong kinetic energy. The kinetic energy of an object is particularly affected by speed. Two objects with a certain mass, as long as they have a relatively large relative speed, will have huge destructive power when they collide. If the two colliding objects are not supported by a strong enough shell, they will be deformed and destroyed because they cannot withstand the external force.
If one of the objects has a solid shell that can protect the internal structure of the object from damage during the collision, then the object will not be damaged, and it may exert a strong squeezing force on the other object and get into the hit object internal.
The ground penetrating projectile uses this principle to penetrate deep underground. The penetration depth of the ground penetrating projectile is closely related to factors such as its weight, the shape of its head, the angle and speed at which it hits the target. The shell of the earth penetrating bomb is generally made of high-strength materials, and the inner and outer surfaces of the shell are also covered with a heat-proof layer.
In this way, when the high-speed moving ground penetrating projectile reaches the ground, its shell will not be cracked, and the ground penetrating projectile will continue to drill down in the direction of the sharp warhead relying on its own huge kinetic energy.
To make a popular analogy, the burrowing principle of the ground penetrating bomb is just like when we drive a nail into a wooden board. When we smash a nail hard, the nail will move down at a very fast speed into the board. However, if the head of the nail is not sharp, it will be difficult to drive in; if the nail is not iron or steel nails, but made of wood, it is also difficult to drive into the board.
Coupled with the coordination function of the delay fuze, it can explode deeply underground.
The so-called fuze is simply a device that detonates the warhead. The fuze of the ground-penetrating projectile can ensure that the ground-penetrating projectile is in a safe state at ordinary times and will not explode. When it penetrates into the ground to a certain depth, it can work according to specific instructions to detonate the warhead in time and produce an explosion.
There are many types of fuzes for ground penetrating bombs. A commonly used one is called a delay fuze. After an ordinary bomb hits the target, the fuse contact in the warhead is turned on, causing the detonator to ignite in less than one millisecond, thereby detonating the explosive. After the ground penetrating projectile hits the target, because the delayed fuze works, the detonator does not ignite at this time, but after a delay of more than 300 milliseconds, it ignites and detonates the explosive.
The destroying effect of ground penetrating projectiles on underground targets is related to factors such as warhead power, ground penetrating depth, and geological conditions around the target. The technology of the ground penetrating projectile involves the science of ground penetrating dynamics, the structure of the ground penetrating device, the material, the guidance and control system, and the target stratum structure. At present, only a few large countries have mastered such technologies. So this kind of bomb is generally difficult to get.
Moreover, this type of bomb carrier is generally cruise missile body, aerial bomb body and rocket, etc. Its carrying function is to make the penetrating warhead reach sufficient speed at the end to produce the effect of going deep underground.
"Nonsense, where do I get this?" Lin Rui shook his head. "Are you going to borrow a Tomahawk missile with a ground penetrating warhead from the Yankees?"
"I know it's hard to get a burr bomb. But we can think of ways to modify it ourselves. Yankee's burr bomb can even go to a depth of 180 meters and explode. We can't use it. We just need to be able to blast through two. Thirty meters is enough. I can try to modify a large-caliber rocket launcher or a 125mm-caliber artillery shell to make a bomb with a penetrating effect." Sausage gestured, "We don't have cruise missiles or planes.
So our bombs can only use multi-stage fuzes. For example, for a solid fortification, after our bomb hits the ground, we first dig into the ground to a certain depth, detonated by fuze A, blast a hole, and the bomb continues to burrow; when it encounters a concrete structure, fuze B detonates again, exploding the concrete structure, and Continue to drill down; when it encounters steel reinforcement fortifications, fuze C detonates; the bomb penetrates the steel plate and enters the bunker before the projectile finally explodes.
