Boeing has been awarded a $21.6 million indefinite-delivery/indefinite-quantity contract modification for sustainment of U.S. Air Force’s GBU-57 Massive Ordnance Penetrator (MOP) “bunker buster” bomb.
This modification extends the ordering period an additional four years and increases the order ceiling price to cover the extension. Work will be performed in St. Louis, Missouri, and is expected to be complete by July 18, 2023.
The modification was awarded by the U.S. Air Force Life Cycle Management Center (AFLCMC) located at Eglin Air Force Base, Florida.
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.
