I know other bombs like the French Durandal have rocket assist for runway work, but how about a massive sprint missile hitting a bunker at mach fuck you? Raytheon, Rocketdyne etc I'm accepting positions at the head of your R&D.

It already has a tungsten alloy in the nose you colossal retard

I thought it was just hardened steel. It's still falling at terminal velocity though, so the rocket assist is valid fag.

>>63903145 (OP)
They are already going back to rocket motors for the GBU-57 replacement. Smaller bomb so more can be carried (the B-21 can only carry one GBU-57) so they're making the replacement like a third of the weight, but making up the difference with rocket engines, proximity fuses, etc.

>so the rocket assist is valid fag.
no, the space you occupy with the rocket will make the bomb have less mass, therefore less penetration

momentum matters more for maintaining velocity during penetration. m*V, you want maximum mass
