Congress has quietly approved to fast track the deployment of the BGU-57A/B or Massive Ordnance Penetrator (MOP). The Pentagon plans to rush the deployment of 10 BGU-57A/B "bunker buster" bombs by June 2010. The MOP is so enormous that it can only be delivered by a B-52 or a B-2A. In fact, the B-2 bombers will need to be refitted in order to carry two MOPs.

The MOP weighs in at a whopping 30,000 pounds, it's warhead weighs in at 5,300 pounds and it can penetrate 200 ft (61 m) of 5,000 psi (34 MPa) reinforced concrete, 26 ft (8 m) of 10,000 psi (69 MPa) reinforced concrete, or 130 ft (40 m) of moderately hard rock.

The Pentagon is accelerating by three years plans for a super bunker buster, the GBU-57A/B or Massive Ordnance Penetrator or MOP, a powerful new bomb aimed squarely at the underground nuclear facilities of Iran and North Korea. The gargantuan bomb—longer than 11 persons standing shoulder-to-shoulder or more than 20 feet base to nose, weighs 30,000 pounds. Some 18 percent of its total weight is comprised of explosives.

Guided by a precision GPS system, the MOP can penetrate an unprecedented 200 feet down before exploding with devastation into an underground bunker, such as those buried in Iran and North Korea currently used to shield rogue nuclear programs. Now Congress has quietly advanced $68 million into the 2009 budget to accelerate the purchase and deployment of ten such super bunker busters making clear they are for possible use against the regimes in Iran or North Korea. Pentagon planners are rushing to beat by months the latest June 2010 deadline for just four such bombs, and have been subsequently directed to increase the number of MOPs to at least ten.

In early July 2009, the Defense Department told a Congressional committee that the MOP was the "weapon of choice" for an “urgent operational need” enunciated by both the U.S. Pacific Command, tasked with North Korea, and the Central Command, tasked with Iran. In doing so, the Pentagon accelerated the program by three years.

The GBU-57A/B MOP is so immense it can only be carried by either a B-52 or a B2a Stealth bomber. The weapon’s explosive power is 10 times greater than its predecessor, the BLU-109. Moreover, the GBU-57A/B MOP is one third heavier than the MOAB dubbed the Mother of All Bombs.
