The BLU-82 Commando Vault, commonly referred to as the daisy cutter, is the largest conventional bomb in the USAF's arsenal. Originally developed for clearing jungle landing zones during the Vietnam Conflict, able to clear a 260 foot radius area. The LZ creation mission was discontinued in 1975 when some Marines took issue with a 15,000 lb. bomb (approximately six times the size of the truck bomb used by Timothy McVeigh in the Oklahoma City bombing) being set off in their vicinity.

The bomb was put back into action 1991, when 11 were used in the opening phases of the Desert Storm ground war, and more recently in Afghanistan as part of Operation Enduring Freedom. Not only used for its massive destructive power against lightly fortified positions but also its ability to clear minefields and the tremendous pyschological impact of the massive explosion and accompanying mushroom cloud.

Along with its size, the method of deployment sets the BLU-82 apart from most other conventional bombs. It is loaded onto a pallet and dropped from a MC-130E, which is a modified version of the C-130 Hercules cargo plane, its descent slowed by a parachute attached to the end of the bomb.
