New Delhi: The United States on Thursday dropped biggest ever non-nuclear bomb on Afghanistan to target its ISIS tunnels. The GBU-43 bomb used in the attack has been nicknamed ‘The Mother of All bombs’, a name that aptly describes the destructive power that it must have.

Here are five quick things to know about this bomb:

The GBU-43/B Massive Ordnance Air Blast (MOAB) is a 21,600-pound, GPS-guided explosive.
This is the first time that the US has used the MOAB bomb in combat.
The bomb, developed by Albert Weimorts of the United States military, was first tested in 2003.
After the tastings, the bomb was manufactured only during the time of Iraq war in the year 2003 but was never used.
Soon, Russia developed its “Father of All Bombs”, touted to be four times as powerful as the MOAB.
