Massive Ordnance Penetrator
Massive Ordnance Penetrator (MOP) is a highly sophisticated, 15-Ton weapon designed to penetrate deep buried bunkers. Built by Boeing, the U.S. Air Force will be utilizing B-2 bombers and GPS guidance to deliver the ordnance. It will be the largest non-nuclear bomb in the U.S. arsenal.  Typical targets can range from clandestine WMD facilities to command-and-control military headquarters. MOP's dimensions are 20 feet long, 31.5" diameter, just shy of 30,000 pounds. Northrop Grumman has led the way equipping MOP into the B-2 fleet since July 2007. Each B-2 is capable of carrying two MOPs.

|“||This awesome weapon reeks of strategic deterrence. America's enemies will know the destructive power of this weapon in our arsenal and they should modify their behavior, lest they learn of this weapon from firsthand experience.||”|
