For the destruction of underground bunkers, special bombs of great length and weight, sometimes consisting of a large amount of heavy metals, have been created. They can penetrate many tens of meters into the ground. But bunkers are being built deeper and deeper. And the capabilities of anti-bunker bombs have to be increased making them longer, heavier and faster. But the size and weight of the bomb is limited by the capabilities of the aircraft, and old ballistic missiles can be used to further increase the speed. However, even this does not allow us to fundamentally increase the depth of destruction of objects under the ground. An interesting option is the second bomb hitting the trail of the first shell. It is very technically difficult. The hole is very small and the bomb drop height is large. Here, the accuracy of indicating the coordinates of GPS or GLONASS is not enough. One of the options is to use a special radio beacon in the bottom of the first shell, which remains in the upper part of the mine. A few meters from the surface of the earth. The radiation of the radio beacon should be in several ranges. When the second projectile approaches, radiation with a higher frequency is used for accurate target designation. The second projectile Uses microwave direction finders in the final phase of the flight until it hits the hole. The large mass and speed of the second projectile make it possible to compensate for a small miss. After hitting the ground, the projectile will "slide" towards the shaft made by the first charge. A microwave marker can provide an accuracy of several decimeters. The big difficulty in accurately targeting the anti-booker bomb at the final stage is its moment of inertia. It is necessary to have time to accurately bring the bomb into the opening of the shaft at the last second of the flight. To do this, you can use small rocket motors that run only once. The necessary impulse is created by choosing the number of motors. https://neoengineering.blogspot.com/2021/08/teoretical-engineering.html
