The GBU-43/B Massive Ordnance Air Blast (MOAB pronounced /ˈm.æb/, commonly known as the Mother of All Bombs) is a large-yield conventional (non-nuclear) bomb, developed for the United States military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory.[1] At the time of development, it was touted as the most powerful non-nuclear weapon ever designed.[2] The bomb was designed to be delivered by a C-130 Hercules, primarily the MC-130E Combat Talon I or MC-130H Combat Talon II variants.

Since then, Russia has tested its "Father of All Bombs", which is claimed to be four times as powerful as the MOAB.[3]

Operational history[edit]

It was first tested with the explosive tritonal on 11 March 2003, on Range 70 located at Eglin Air Force Base in Florida. It was again tested on 21 November 2003.[2] Aside from two test articles, the only known production is of 15 units at the McAlester Army Ammunition Plant in 2003 in support of the Iraq War. A single MOAB was moved to the Persian Gulf area in April 2003 but it was never used.[4] Since none of those are known to have been used as of early 2007, the U.S. inventory of GBU-43/B presumably remains at approximately 15.

Evaluations[edit]

The basic operational concept bears some similarity to the BLU-82 Daisy Cutter, which was used to clear heavily wooded areas in the Vietnam War and in Iraq to clear mines and later as a psychological weapon against the Iraqi military. After witnessing the psychological impact of the BLU-82 on enemy soldiers, and not having any BLU-82 weapons remaining, the MOAB was developed partly to continue the role of intimidating the Iraqi soldiers. Pentagon officials had suggested their intention to use MOAB as an anti-personnel weapon, as part of the "shock and awe" strategy integral to the 2003 invasion of Iraq.[5]

The MOAB is not a penetrator weapon and is primarily intended for soft to medium surface targets covering extended areas and targets in a contained environment such as a deep canyon or within a cave system. However, multiple strikes with lower yield ordnance may be more effective and can be delivered by fighter/bombers such as the F-16 with greater stand-off capability than the C-130 and C-17. High altitude carpet-bombing with much smaller 230 to 910 kilograms (500 to 2,000 lb) bombs delivered via heavy bombers such as the B-52 or B-2 is also highly effective at covering large areas.[6]
