The GBU-43 MOAB (Massive Ordnance Air Blast) is the most powerful conventional bomb in the world. It is in service with the US Air Force since 2003. It is also part of the British Royal Air Force’s arsenal. According to some military sources, two of the 15 MOABs in US inventory might have been used in Iraq and Afghanistan to attack powerful enemy strongholds. It was first tested at Eglin Air Force Base, Florida, in March 2003. Produced by the McAlester Army Ammunition Plant, it can be dropped from C-130 Hercules cargo aircraft as well as from B-52 Stratofortress and B-2 Spirit bombers.

The GBU-43 is not a dumb bomb, for it is fitted with a guidance system. From the moment is dropped, GPS and an internal gyroscope guide the bomb towards its target, exploding a couple of meters just before impact. Although it is not a penetration bomb, the MOAB was designed to unleash the most powerful blast that has ever been produced from a non-nuclear weapon and is employed to attack huge concentration of enemy ground troops.
