The GBU-57A/B Massive Ordnance Penetrator (MOP) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force.[2]

he Massive Ordnance Penetrator (MOP) is a weapon system designed to accomplish a difficult, complicated mission of reaching and destroying an adversary's weapons of mass destruction located in well-protected facilities.[3]

On 14 November 2011, Bloomberg reported that the Air Force Global Strike Command started receiving the Massive Ordnance Penetrator and that the deliveries "will meet requirements for the current operational need".[15] The Air Force now has received delivery of 16 MOPs as of November 2011.[16] And as of March 2012, there is an "operational stockpile" at Whiteman Air Force Base.[17]

In 2012, the Pentagon requested $82 million to develop greater penetration power for the existing weapon.[1] A 2013 report stated that the development had been a success,[18] and B-2 integration testing began that year.[19]

ALTHOUGH-On 13 April 2017, a MOAB was dropped[15] on an ISIS-Khorasan cave complex in Achin District, Nangarhar Province, Afghanistan. It was the first operational use of the bomb.[3][16][17] Two days later, an Afghan army spokesman said that the strike killed 94 ISIS-K militants, including four commanders, with no signs of civilian casualties.[18]

It was too dangerous to send troops...

Never send a Marine when you can send a bullet.
A larger bullet is better than a smaller bullet.
