The BLU-82 "Daisy Cutter" and Fuel Air Explosives: Somewhat OT, but to paraphrase Clausewitz, perhaps the BLU-82 is foreign affairs by other means. Anyway, our esteemed fearless leader fl asked me about this back in #reply-16612372 , but I dropped that query. So I did a little research. It's not stated as such in the straightforward references, but I think the BLU-82 pretty clearly operates as some form of FAE. Consider: Warhead (lbs.) 15,000 Explosive Aluminum Powder (12,600 lbs.) (http://www.fas.org/man/dod-101/sys/dumb/blu-82.htm) Compare this to a more self-contained application using Aluminum as an energy source: The propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent). csar.uiuc.edu I did some (very) rough calculations in my head last night, to get enough oxygen to take 12600 lbs. of Al to the Al203 state would be about a 70 ft. cube of atmosphere, or maybe a 100 foot diameter hemisphere. Aluminum seems to have about the same energy density, pound for pound, as hydrocarbons, when taken down to the fully oxidized state.

Big Bomb!!! 'Daisy Cutter' clears a path to the Taliban By Wayne Specht, Stars and Stripes The bomb is so big, it can’t be dropped. It has to be pulled by parachute out the back of a cargo plane. And the Air Force unleashed it over Afghanistan. The BLU-82, a 15,000-pound fuel-air explosive bomb dubbed “Daisy Cutter,” was dropped on Taliban positions behind the front lines on Sunday, The Associated Press reported. It earned its nickname because it is detonated about three feet above ground, and it clears a 900-foot radius. Large weapons such as the Daisy Cutter are viewed not only as intense firepower, but also as psychological pressure on Taliban and al-Qaida forces. More precise target information from Russia and from U.S. special operations forces on the ground have helped the United States escalate attacks on caves and tunnels in Afghanistan that have been identified as Taliban arms depots and command centers, the AP said. The Daisy Cutter was first used by the Air Force in the final year of U.S. involvement in the Vietnam War for clearing thick jungle areas to create instant landing zones for Army helicopters. Air Force documents call the BLU-82B weapon system “Commando Vault.” It is a general-purpose “dumb bomb” loaded aboard newer versions of the C-130 Hercules, a four-engine workhorse used by the Air Force for more than 30 years. Because the bomb lacks a tail fin assembly, the same parachute that pulls the weapon from the back of the C-130 keeps its nose down as it falls. The warhead contains 12,600 pounds of explosives and is detonated just above the ground by a 38-inch fuse probe extending from the bomb’s nose. It produces enough power to level trees and buildings. Eleven BLU-82s were dropped during Operation Desert Storm, all from special operations C-130s known as Combat Talons. The initial drops were intended to test the bomb’s ability to clear mines; however, no reliable assessment was completed because the war didn’t last long enough. The crew of a MC-130E Combat Talon special operations airplane dropped a BLU-82 bomb near an Iraqi position. The bomb detonated in an explosion that momentarily lit up the entire front. A leaflet drop warned Iraqi soldiers more such bombs would be dropped on their positions; the threat was believed to be responsible for mass defections, including almost all of one Iraqi battalion’s staff. Each Daisy Cutter costs $27,316, according to the Federation of American Scientists Web site.
