The US Air Force Just Ended Boeing's Monopoly On Its Most Strategic Bunker-Buster With A $149 Million Deal
The US Air Force awarded a $149M contract to four small steel companies (Superior Forge, Ellwood, Faxon, Grand Valley) to manufacture casings for the GBU-57 bomb, ending Boeing's 18-year monopoly. The move aims to diversify production and address supply shortages, with work extending through 2033. Boeing's past delays and the recent use of the bomb in operations prompted this change.
