The BLU-82B/C-130 weapon system, known under program "Commando Vault" and nicknamed "Daisy Cutter" in Vietnam for its ability to flatten a section of forest into a helicopter landing zone, is an American conventional bomb, delivered from either a C-130 or MC-130 transport aircraft or a CH-54 heavy-lift "SkyCrane" helicopter from the 1st Air Cavalry. A total of 225 were constructed. It was successfully used during military operations in Vietnam, the Gulf War and Afghanistan. The BLU-82 was retired in 2008 and replaced with the more powerful &lt;a href="GBU-43/B%20MOAB"&gt;GBU-43/B MOAB&lt;/a&gt;.
