What is 20 feet long, weighs 30,000 pounds and can bury itself 200 feet into the ground? No, I really doubt your mother-in-law is 20 feet long. The answer is the U.S. Air Force's latest breakthrough in advanced weaponry; the Massive Ordnance Penetrator (MOP). The MOP is a non-nuclear, "ultra-large bunker-buster bomb." Bunker-busters are designed to destroy deeply buried bunkers or underground facilities by burying themselves into the earth before exploding. Carrying more than 5300 pounds of explosives, The MOP can penetrate 200 feet before exploding.
The MOP is roughly one-third heavier than the 21,000-pound Massive Ordnance Air Blast (MOAB) bomb, dubbed the "Mother of All Bombs." In addition, The MOP's predecessor, the BLU-109, is a mere 2,000 pounds with 535 pounds of explosives, meaning the MOP would deliver 10 times the explosive power.
The Air Force and Department of Defense are looking to accelerate its development, hoping that its radar-evading B-2 bomber will be carrying this sucker by July 2010.
