    Although Crystal provided enough information, Lin Rui's intelligence team was not idle either.

    Since the incident with the CIA, Lin Rui has always had a requirement, that is, all intelligence must be carefully verified, and try to rely less or less on intelligence from external sources.

    Vitak¡¯s intelligence also confirmed the existence of the terrorist camp.

    "That is a large base that originally belonged to the West African branch of the Jihad Alliance. They have been operating there for many years. Although they are not as powerful as before, they still have hundreds of people." Vitak nodded and said, "There is indeed news that there is a group of Chechens in  They are there. But the specific situation is unknown.

    As for the underground facilities of that base, we don¡¯t have time to explore them.  But judging from the map provided by Crystal, their surveying was quite accurate, especially the details, which they handled quite well.  So in my opinion, this map should be the mapping done by insiders of the terrorist organization, and it cannot be fake.  "

    "That is to say, there is no need to doubt the authenticity of the intelligence. My opinion is that this intelligence can be trusted. However, we still need to pay great attention to the details of the operation." Shogan nodded.

    Lin Rui was silent for a while and said, "In this case, we will proceed as planned. Bring the map."

    Vitak 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 located 20 kilometers away from the enemy base. Crystal and her people will provide us with 4 Kestrel armed helicopters, which will also be placed at the headquarters.  all around 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 carry out directional blasting from this position.  Blast their tunnels directly and enter their underground fortifications.  Sausage, you are an expert in blasting, do you have any difficulty in this aspect?  "

    "I noticed that their underground fortification structure is quite simple, but the shallowest position is 20 meters from the ground. And the location we chose to invade is here, 30 meters from the ground. With our current blasting capabilities, I'm afraid  It is difficult to blow through directly. Because their interior is reinforced with reinforced concrete, we need high-power bombs." Sausage replied.

    "Look for the crystal to provide it to you. She can get any weapon." Lin Rui nodded.

    "I'm afraid she won't be able to help with this, unless she has great powers and can get the ground-penetrating warhead. Then use a Tomahawk cruise missile, using joint GPS guidance, with a load of up to 450 kilograms and a charge diameter of 50 centimeters, so that  The bomb's ground speed reaches 260 to 335 meters per second. It also needs to use an MWS warhead, which can drill through 6 to 9 meters of soil and then drill through 3.6 to 5.5 meters of concrete to detonate 23 to 70 kilograms of explosives." Sausage shook his head.

    "Need a ground-penetrating bomb?" Lin Rui frowned.

    Ordinary bombs will explode as soon as they hit the ground, but ground-penetrating bombs have their own unique trick: when they hit the ground, they will not explode immediately. Instead, they will continue to drill down. When they reach a certain depth, they will explode.  Thereby destroying targets deep underground.  General ground-penetrating bombs can penetrate hundreds of millimeters of concrete.

    The reason why this kind of ground-penetrating bomb can penetrate deep into the ground is achieved by its powerful 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 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 strong shell that can protect the internal structure of the object from damage during a collision, then the object will not be damaged, but it may exert a strong squeezing force on the other object and penetrate into the hit object.  internal.

    Earth-penetrating bombs use this principle to drill deep underground.  The penetration depth of an earth-penetrating bomb is closely related to factors such as its weight, the shape of its head, the angle and speed of impact on the target, and other factors.  The shell of an earth-penetrating bomb is generally made of high-strength materials, and a heat-proof layer is applied to the inner and outer surfaces of the shell.

    In this way, when the high-speed earth-penetrating bomb reaches the ground, its shell will not be cracked, and the earth-penetrating bomb will rely on its own huge kinetic energy to continue drilling downward in the direction of the sharp warhead.

    To use a popular metaphor, the ground-penetrating principle of an earth-penetrating bomb is like driving nails into a wooden board.  When we hit a nail hard, the nail will move downward at an extremely fast speed and penetrate the board.  However, if the head of the nail is not pointed, it will be difficult to drive in; if the nail is not an iron nail or a steel nail, but made of wood, it will also be difficult to drive into the board.

    With the cooperation of the delayed fuse, it can explode deep underground.

    The so-called fuze, simply put, is the device that detonates the warhead.  The fuse of the earth-penetrating bomb can??It ensures that the earth-penetrating bomb is in a safe state and does not explode. When it penetrates a certain depth underground, it can work according to specific instructions to detonate the warhead in a timely manner and produce an explosion.

    There are many types of fuzes for ground penetrating bombs.  One commonly used one is called a delay fuze.  After an ordinary bomb hits the target, the fuze contact in the warhead is connected, causing the detonator to fire in less than one millisecond, thereby detonating the explosive and causing an explosion.  When the earth-penetrating projectile hits the target, the detonator does not fire because the delay fuze works. Instead, it fires and detonates the explosive after a delay of more than 300 milliseconds.

    The destruction effect of ground-penetrating bombs on underground targets is related to factors such as the power of the warhead, the depth of ground penetration, and the geological conditions around the target.  The technology of earth-penetrating bombs involves the science of earth-penetrating dynamics, earth-penetrating device shell structure, materials, guidance and control systems, and target formation structure.  Currently, only a few major countries have mastered this type of technology.  Therefore, this kind of bomb is generally difficult to obtain.

    And this type of bomb carrier is generally a cruise missile body, an aerial bomb body, a rocket, etc. Its carrying function is to enable the penetrating warhead to reach a sufficient speed in the final stage, so as to produce the effect of going deep into the ground.

    "Nonsense, where are we going to get this?" Lin Rui shook his head.  "Are you going to borrow a Tomahawk missile with an earth-penetrating warhead from the Americans?"

    "I know it's hard to get ground-penetrating bombs. However, we can think of ways to modify them ourselves. The Yankees' ground-penetrating bombs can even penetrate 180 meters underground and explode, but we don't have to use them. We only 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 similar penetrating effect." Sausage gestured, "We have no cruise missiles and no aircraft to drop them.

    So our bombs can only use multi-stage fuzes.  For example, in a solid fortification, after our bomb touches the ground, it first penetrates into the ground to a certain depth, is detonated by fuze a, and explodes a hole, and the bomb continues to drill into the ground; when it encounters a concrete structure, fuze b is detonated again, blasting the concrete structure, and  Continue to drill down; when encountering steel plate reinforcements, fuze C detonates; the bomb penetrates the steel plate and enters the bunker, and the bomb body finally explodes.  "
