Bunker buster bombs FORTE Bunker busters have reached their limits in terms of length and weight. Even large transport aircraft like the Globemaster are unlikely to be able to use bombs larger than the GBU-57. It is possible to radically increase the depth of destruction of bunkers by using a series of two bombs, if the second one hits the channel already made by the first bomb. Moreover, the first bomb can be inert, without an explosive charge. https://theoryinnovations.blogspot.com/
