There’s a lot of work underway to improve both the accuracy and lethality of military munitions; one of those is the small diameter bomb. The small diameter bomb can be carried by a variety of attack and/or ground support aircraft. It has a blast radius of 26 feet. To put that in perspective for our readers, the M67 fragmentation grenade has an injury radius of ~ 45 feet (15 meters) and a kill radius of ~15 feet (5 meters). The small diameter bomb is a 250 pound ordnance. Precisely the capability that was need in a situation like Benghazi.
Take a look at this GBU-39/B SDB I and GBU-53/B SDB II capabilities demonstration.
