So, as you know, shaped charge (eg HEAT) warheads were used during WWII as tank killers, and I believe against some fortresses as well. This may be a stupid question, but why were they never used in bigger applications? For example, I could see a 1,000kg shaped-charge bomb, dropped from a dive bomber, peircing a carrier deck and wrecking havoc in the hanger. A bomb like that might also give you a better chance of knocking out an armored turret on a battleship.
Is there a good reason for not using these that I have missed? Is it more effective somehow to just use all the bomb's space for explosives (leaving no room for a cavity)? Is it too complicated or expensive? What do you think?
