C-5 Modernization Program

Improving Reliability, Efficiency and Availability

As part of Lockheed Martin’s sustainment offerings, C-5 modernization provides greatly improved reliability, efficiency, maintainability and availability, while ensuring this critical national strategic airlift resource continues serving the warfighter well into the 21st century.

Since its inception, the C-5 has been a critical instrument of national policy. From the defense of Israel in the Yom Kippur war, to the air bridge supporting coalition forces in Desert Storm, the C-5 delivers unmatched capability to carry enormous loads over global distances.

The C-5M Super Galaxy is the result of a two-phase modernization effort: the Avionics Modernization Program (AMP) and the Reliability Enhancement and Re-engining Program (RERP).

AMP adds a new, modern cockpit with a digital, all-weather flight control system and autopilot; a new communications suite; flat-panel displays; and enhanced navigation and safety equipment. Enhancements such as the integrated datalink capabilities, predictive flight performance cues and situational awareness displays (the Enhanced Ground Proximity Warning System) greatly ease crew workload and enhance situational awareness. AMP is the digital backbone to support RERP.

Now, with more powerful GE CF6-80C2 commercial engines (military designation F138-GE-100) engines and 70 major enhancements, the C-5M Super Galaxy can deliver the globe in one flight, unrefueled. The C-5M is an airlift revolution. With more capability, reliability and affordability than its predecessors, the world record-setting C-5M is rewriting the strategic airlift playbook. The new engine produces more than 50,000 pounds of thrust – a 22 percent increase over current TF39 engines – and is Stage IV noise compliant. The C-5M also has a 58 percent greater climb rate to an initial cruise altitude that is 38 percent higher than the current C-5. This capability delivers fuel savings greater than 20 percent compared to other airlifters. With improved reliability and unmatched range and payload capability, the C-5M provides our nation with the ability to respond to a crisis anywhere in the world with the largest payload of vital supplies on a moment’s notice. The newly modernized C-5M Super Galaxy will be the global leader in strategic airlift for decades to come.


The Original Equipment Manufacturer (OEM) Difference – Proven Performance

The C-5 modernization approach is proven. In three flights operating out of Dover AFB, Delaware, a joint U.S. Air Force and Lockheed Martin crew set 43 world aviation records, demonstrating the C-5M’s ability to redefine global airlift. In deployed airlift operations, the C-5M is demonstrating a new era of highly capable, reliable and affordable airlift. With departure reliability rates greater than 90 percent and payload increases of 20 percent over legacy C-5s, the Super Galaxy is delivering more to the warfighter on every mission. With a substantial improvement in unrefueled range, the C-5M is overflying traditional en-route fuel stops, enabling a reduction in fuel consumption by as much as 20 percent. This is the OEM difference.
