On August 2, Lockheed Martin handed over the 52nd C-5 Galaxy to undergo the U.S. Air Force’s RERP (reliability enhancement and re-engining program) upgrade, after which the aircraft are known as the C-5M Super Galaxy. With the RERP program complete, the Air Force’s fleet of C-5Ms is expected to serve into the 2040s.
