The Massive Ordnance Air Blast (MOAB) - also known as "the mother of all bombs" - is the US's largest non-nuclear bomb weighing in at over 21,000 thousand pounds.The bomb was used in combat for the first time on Thursday, when it was dropped on an ISIS camp in a rural area of Afghanistan.
The bomb is so big that it has to be dropped by a C-130 transport plane. The bomb's incredible destructive power makes it ideal for hardened targets like ISIS' network of tunnels and bunkers in Afghanistan.
Video of a MOAB being tested can be viewed below. For perspective, the MOAB's blast stretches a mile in each direction.
