this is nonsense. it uses a shaped charge to blast a hole and then the warhead goes through that hole, the angle has no effect

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.
