MOAB = Massive Ordinance Air Blast
The MOAB is not a penetrator weapon and is primarily an air burst ordnance intended for soft to medium surface targets covering extended areas and targets in a contained environment such as a deep canyon or within a cave system.[7] High altitude carpet-bombing with much smaller 230-to-910-kilogram (500 to 2,000 lb) bombs delivered via heavy bombers such as the B-52, B-2, or the B-1 is also highly effective at covering large areas.[8]
