you're a spastic. the bomb is a shaped charge and a follow through warhead.

shaped charge cuts a hole and the warhead behind goes through that hole. modern bunker besters all use that principle.

GBU 57 uses a shaped charge to drill a hole and the warhead goes through the hole into the bunker.

This is probably classified but if you look at the wikipedia of the gbu 57, it mentions that it contains "The warhead assembly contains 4,590 pounds (2,082 kg) of AFX-757 and 752 pounds (341 kg) of PBXN-114"

the smaller fraction of PBXN is probably used to drive a shaped charge in a similar manner as the stormshadow/scalp in bunker buster mode.


i asked chatgpt about copper shaped charge penetration on a theoretical 341kg PBXN shaped charge and it lines up roughly.

this bomb doesnt simply rely on freefall kinetic energy for penetration, it blasts a hole and then the warhead goes through that hole
