The first C-5M Super Galaxy is now at Dover AFB, Del., undergoing its first isochronal inspection—a process that takes about 14 days and that every C-5 must undergo about every 420 days to ensure it meets safety and operations standards. The use of the M designation means the aircraft has undergone the complete Aircraft Modernization Program and Reliability Enhancement and Re-engining Program the Air Force is currently testing for the C-5 fleet. Lockheed Martin finished work on this first M model last spring.
A combined Navy and Air Force program is seeking to build a smaller version of a ubiquitous air-to-air missile that could give advanced aircraft, such as the Collaborative Combat Aircraft, greater magazine depth in a high-end fight.
