C-5M Super Galaxy

The AMP package installation on US Air Force C-5s started in June 2004 and is expected to last several years. In October 2004, the first C-5 AMP was delivered to Lockheed-Martin to undergo RERP upgrade modifications. The RERP program will see the first C-5 aircraft taking to the air in October 2005 or later for testing powered by four fuel efficient F138-GE-100 engines (a CF6-80C2 derivative). The test program is expected to complete in 2007. The C-5 aircraft that had received both AMP and RERP modifications will be re-designated C-5M Super Galaxy. As of early 2006, the USAF plans call for 112 C-5A/B aircraft to undergo C-5M modernization program through 2020. The program was scoped for only 52 C-5M delivered by August 2018 and to remain in active duty in the 2040s. The C-5A/B Reliability Enhancement and Re-engining Program (RERP) includes new F103 engines (a derivative of proven CF6 commercial engines), pylons and auxiliary power units, with upgrades to aircraft skin and frame, landing gear and the pressurization system. Overall RERP includes more than 70 system and equipment improvements. AMP and RERP programs will restore C-5's maintainability and reliability, maintain structural and system integrity, reduce overall ownership costs and increase operational capability well into the 21st century. Overall, the C-5 upgraded aircraft fleet mission capable rate would represent at least 75 percent. The US Air Force (USAF) long-term goal is to keep the C-5 strategic transport aircraft fleet viable for the next 40 years. In actual facts, AMP program is the first phase of such effort, while RERP program will act as the second phase leading to the fully upgraded C-5 aircraft.
