The mother of all bombs known as the most powerful conventional bomb in the American arsenal was dropped by the US on a tunnel complex used by Islamic State of militants in Afghanistan on Thursday.
The bomb is officially called the GBU-43/B Massive Ordnance Air Blast — hence its moniker — hit a tunnel complex in the Achin district of Nangarhar Province, according to a statement from the United States military in Afghanistan.
The GBU-43—is a 22,600lbs weapon with 18,700lbs of H-6 explosive filler—is an inertially guided weapon that relies on GPS course corrections just like the JDAM series weapons. When the GBU-43/B was originally developed, it was the most powerful non-nuclear bomb ever built—but has been surpassed by other weapons.
Reports do not indicate how many militants were killed.
