Of the 79 aircraft to receive the first stage of upgrades, 52 are slated to receive a second set that includes new General Electric CF6 engines, and will be redesignated as the C-5M Super Galaxy.
In service since 1970, the C-5 is the largest US airlifter and one of the world’s biggest military aircraft. The C-5M upgrades are designed to improve the airlifter’s spotty reliability record and keep the C-5 in service through to 2040.
The final C-5 aircraft to receive the AMP upgrades will be assigned to the Air Force Reserve’s 443d Airlift Wing at Lackland Air Force Base in Texas.
