The Air Force awarded Boeing a $21.6 million contract modification for GBU-57 Massive Ordnance Penetrator, also known as a “bunker buster“ bomb.
The bunker buster is a precision-guided, 30,000 pound bomb employed only by the B-2 Spirit stealth bomber. Once released from the bat-winged bomber, the MOP is guided to targets by GPS and a pair of stubby fins. It was designed to attack deeply buried bunkers and tunnels and carries 5,300 pounds of explosives. GBU-57 was first tested in 2009.
The modification provides for sustainment work. Boeing will perform work in Missouri and expects completion by July 18, 2023.
