What Is the Mother of All Bombs? US Weapon Explained
The name “Mother of All Bombs” sounds dramatic, but it refers to a real US weapon. The GBU-43/B Massive Ordnance Air Blast bomb, or MOAB, is drawing attention amid reports that the US military has considered it for possible future strikes on Iran. Here is the “Mother of All Bombs explained: what it is, how it got its name and why it matters.
What Is the Mother of All Bombs?
The MOAB is a GPS-guided conventional bomb developed by the US Air Force Research Laboratory. It weighs about 9,800 kilograms, measures around 9.1 metres long and carries roughly 8,480 kilograms of explosives. Its blast is described as having the force of about 11 tonnes of TNT.
The weapon is designed to strike large targets, including enemy positions and tunnel or cave networks. But “non-nuclear” does not mean safe: a blast of this size can cause extreme destruction and put people and buildings nearby at risk. Unlike a nuclear weapon, it does not create radioactive fallout from a nuclear reaction.
Why Is It Called That?
MOAB is short for “Massive Ordnance Air Blast”, its official name. “Mother of All Bombs” is the widely used nickname, linked to its great size and destructive power. The phrase also echoes “mother of all battles”, an expression used by former Iraqi leader Saddam Hussein during the 1991 Gulf War. The US Air Force itself used the nickname in a 2008 article about the weapon.
The bomb was developed and tested in 2003, but it was not used in combat until April 13, 2017. On that date, the US dropped it on an Islamic State cave and tunnel network in Afghanistan’s Nangarhar province, near the Pakistan border. Afghanistan’s defence ministry said up to 36 suspected militants were killed. That figure was not independently verified, according to reports at the time.
Why Is It in the News Now?
On October 15, Reuters reported that CNN said US plans for possible future strikes on Iran could include the MOAB against energy infrastructure and nuclear sites if President Donald Trump ordered renewed combat. Reuters said it could not immediately verify the report. This is a reported option, not confirmation that the bomb has been used in Iran or that an attack has been approved.
The MOAB’s nickname may grab attention, but its real significance lies in the scale of destruction it can cause. Understanding the weapon means separating dramatic language from verified facts and remembering the human cost that any use of such a powerful bomb could bring.
