Boeing Awarded Contract for GBU-57 Massive Ordnance Penetrator Bunker Buster Bombs

Boeing has been awarded a contract, worth around $21 million, for the delivery of GBU-57 Massive Ordnance Penetrator (MOP) bunker buster bombs to the U.S. Air Force (USAF).

The contract was awarded by the U.S. Air Force Life Cycle Management Center (AFLCMC) located at Eglin Air Force Base, Florida. Fiscal 2016 production funds for the contract amount are being obligated at the time of award.

This award is the result of a sole-source acquisition and the work will be performed in St. Louis, Missouri, and is expected to be complete by July 31, 2020.

GBU-57A/B Massive Ordnance Penetrator (MOP)

GBU-57A/B Massive Ordnance Penetrator (MOP) is a U.S. Air Force (USAF), precision-guided, 30,000-pound (14,000 kg) “bunker buster” bomb.

This 20-foot long GPS-guided bomb is substantially larger than the deepest penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37 GAM (GPS-Aided Munition).

The GBU-57A/B is armed with a 5,300 pound warhead and can penetrate 200 ft (61 m) of 5,000 psi (34 MPa) reinforced concrete, 26 ft of 10,000 psi reinforced concrete or 130 ft of moderately hard rock. For this reason it is considered the weapon of choice in case of attack on buried targets.

The B-2 Spirit stealth bomber is the only USAF aircraft currently capable to operationally drop the massive bomb, even though the testing of the MOP in 2009 involved a B-52 Stratofortress strategic bomber.
