The second C-5 Galaxy strategic transport was inducted into the Reliability Enhancement and Re-engining Program, or RERP, production line at the Lockheed Martin facility in Marietta, Georgia, on 13 January 2010. The RERP modifications consist of more than seventy improvements and upgrades to the C-5 airframe and aircraft systems and include the installation of new higher thrust, more reliable CF6-80C2 turbofan engines. The second aircraft to enter the RERP production line is a C-5B based at Dover AFB, Delaware. This aircraft, Air Force serial number 85-0002, currently has more than 19,000 flight hours. The aircraft is scheduled to return to service in early 2011.
