The Mother of All Bombs (MOAB)

The Mother of All Bombs (MOAB) or the GBU-43/B Massive Ordnance Air Blast 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. At the time of development, it was touted as the most powerful non-nuclear weapon ever designed. 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.

The Mother of All Bombs (MOAB)The MOAB was first dropped in combat in the 13 April 2017 airstrike against an Islamic State of Iraq and the Levant – Khorasan Province (ISIS) tunnel complex in Achin District, Afghanistan.

The basic principle resembles that of the BLU-82 Daisy Cutter, which was used to clear heavily wooded areas in the Vietnam War. Decades later, the BLU-82 was used in Afghanistan in November 2001 against the Taliban. Its success as a weapon of intimidation led to the decision to develop the MOAB. Pentagon officials suggested MOAB might be used as an anti-personnel weapon, as part of the "shock and awe" strategy integral to the 2003 invasion of Iraq.

GBU-43s are delivered from C-130 cargo aircraft, inside which they are carried on cradles resting on airdrop platforms. The bombs are dropped by deploying drogue parachutes, which also extract the cradle and platform from the aircraft. Shortly after launch, the drogues are released and bombs fall unretarded, without the use of a retarding parachute. GPS satellite-guidance is used to guide bombs to their targets. More details
