Lockheed Martin has delivered the 52nd C-5M Super Galaxy strategic transport modernised under the US Air Force’s Reliability Enhancement and Re-engining Programme.
The delivery completes the RERP upgrade, which extends the service life of the C-5 fleet out until the 2040s.
“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,
“I am very proud of the contractor-government team than carried out the C-5 fleet modernisation effort. We’ve worked very hard to ensure the C-5Ms are the absolute best strategic airlifters possible for our armed forces.”
A US Air Force Reserve Command aircrew from the 439th Airlift Wing at Westover Air Reserve Base, Massachusetts, ferried the final C-5M to Stewart Air Force Base, New York, where the aircraft will undergo interior paint restoration. Once that work is complete, the aircraft will be flown to Westover where it will be the eighth C-5M assigned to the base, say Lockheed.
Lockheed Martin began RERP development work in 2001. RERP incorporates more than 70 improvements that improve 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 heart of the system is the GE F138 turbofan engine (known as a CF6-80C2L1F in the commercial world) de-rated to 50,000 pounds of thrust on the C-5M. This engine provides 22 percent more thrust than the out-of-production TF39 turbofans on the earlier C-5A/B/C aircraft. The engines also allow the C-5M to meet the FAA’s Stage 4 noise reduction requirements.
These changes, taken together, result in a 22 percent increase in thrust, a shorter takeoff roll; a 58 percent improvement in climb rate; allows the C-5M to cruise—at maximum gross weight—in the Communication/Navigation/Surveillance / Air Traffic Management (CNS/ATM) flight environment; and greatly enhanced fuel efficiency and less tanker support demand.”
