Just for clarification:
MOAB is a guided bomb which delivers the 18,700 lb BLU-120/B warhead bomb with KMU-593/B GPS/INS. The MOAB is the largest-ever satellite-guided, air-delivered weapon in history [not the largest ever, but the largest satellite guided]. The 21,600-pound MOAB is an improved replacement for the unguided 15,000-pound BLU-82 Daisy Cutter. It is 30 feet long with a diameter of 40.5 inches. The warhead is a blast-type warhead. It was developed in only nine weeks to be available for the Iraq campaign, but it was not used in combat.
The 21,700-pound [9,500 kilogram] bomb contains 18,700 pounds of H6, an explosive that is a mixture of RDX (Cyclotrimethylene trinitramine), TNT, and aluminum. H6 is used by the military for general purpose bombs. H6 is an Australian produced explosive composition. Composition H6 is a widely used main charge filling for underwater blast weapons such as mines, depth charges, torpedoes and mine disposal charges. HBX compositions (HBX-1, HBX-3, and H6) are aluminized (powdered aluminum) explosives used primarily as a replacement for the obsolete explosive, torpex. They are employed as bursting charges in mines, depth bombs, depth charges, and torpedoes. HBX-3 and H-6 have lower sensitivity to impact and much higher explosion test temperatures than torpex. The MOAB weapon produces a very large explosive blast, with lesser fragmentation effects due to a thin-walled aluminum casing.
Contrary to some published claims, it most certainly is not an Ethylene-Oxide Fuel-Air Explosive (FAE).
Thanks. Good info.
