Lockheed Martin has delivered the 79th and final C-5 Galaxy airlifter to undergo a first phase of upgrades under a two-stage modernisation program.

The Avionics Modernization Program (AMP), as the first phase of upgrades is known, incorporates a mission computer, a glass cockpit with digital avionics, an autopilot system, and updated communications, navigation and surveillance components. The AMP began in 1998.

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.
