Lockheed Martin has completed the delivery of modernised C-5M Super Galaxy strategic transports under the US Air Force’s Reliability Enhancement and Re-engining Program (RERP).
The recent delivery of the 52nd C-5M Super Galaxy, marks the completion of the RERP upgrade, which extends the service life of the C-5 fleet out until the 2040s. A total of 49 C 5Bs, two C-5C aircraft, and one original C-5A was modified under RERP.
“With the capability inherent in the C-5M, the Super Galaxy is more efficient and more reliable, and better able to do its job of truly global strategic airlift,” said Patricia Pagan, Lockheed Martin Air Mobility and Maritime Missions Strategic Airlift director.
Lockheed Martin commenced development work as part of RERP in 2001, which incorporated more than 70 improvements towards reliability, efficiency, maintainability and availability.
RERP included changes or modifications to the airframe structure; environmental and pneumatic systems; hydraulic systems, electrical system; fuel system; landing gear; and flight controls.
The new GE F138 turbofan engine (known as a CF6-80C2L1F in the commercial world) is de-rated to 50,000 pounds of thrust on the C-5M but still provides 22 percent more thrust than the out-of-production TF39 turbofans on the earlier C-5A/B/C aircraft.
The C-5 Galaxy is the largest strategic airlifter in the US Air Force’s fleet and has been operational since 1970.
