The United States on Thursday dropped the GBU-43 Massive Ordnance Air Blast bomb, known as “the mother of all bombs,” on ISIS in Afghanistan.
The “mother of all bombs” was first developed by Albert Weimorts in 2003 for use in the Iraq War. It is the United States’ largest non-nuclear bomb, and it explodes in the air above its target, creating an “overblast” which destroys tunnels, according to Business Insider.
The 22,600-pound GPS-guided bomb was never used in combat before Thursday. It was tested twice at Eglin Air Force Base in Florida in 2003.
The bomb is just over 30 feet long and 40.5 inches in diameter and needs to be carried by a large transport plane. It creates a blast radius of a mile in each direction, according to the History Channel. Russia claims to have a bomb that is four times as powerful as the MOAB, which it calls “the father of all bombs.”
Each bomb costs $16 million per unit and the government has spent $314 million on GBU-43s, according to the military website Deagel.
