Tarmac-shredding penetration bombs

Tarmac-shredding penetration bombs are systems involving bombs or bomblets which are designed to disrupt the surface of a runway and make it unusable for flight operations. One early system was the BLU-107 Durandal, a single 450 lb bomb with rocket booster and 330 lb warhead. Another, now withdrawn from service, was the JP233, a submunitions system in which an aircraft would fly over the target runway and a mixture of penetrating and anti-personnel submunitions would be dispensed to both crater the runway and impede repair work.
