April 15 (UPI) -- Boeing was awarded a $21.6 million contract for sustainment of U.S. Air Force's GBU-57 Massive Ordnance Penetrator, known as a "bunker buster" bomb, designed for use with the B-2 Spirit stealth fighter.
This extends the ordering period for the MOP by an additional four years and increases the order ceiling price to cover the extension, the Defense Department announced Friday.
