The Lockheed C-5 Galaxy is a large military transport aircraft originally designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin. It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo. The Galaxy has many similarities to the smaller Lockheed C-141 Starlifter and the later Boeing C-17 Globemaster III. The C-5 is among the largest military aircraft in the world.
New C-5 cockpit avionics, installed under the Avionics Modernization Program
Following a study showing that 80% of the C-5 airframe’s service life was remaining,[99] Air Mobility Command (AMC) began an aggressive program to modernize all remaining C-5Bs and C-5Cs and many of the C-5As. The C-5 Avionics Modernization Program (AMP) began in 1998 and includes upgrading the avionics to comply with Global Air Traffic Management standards, improving communications, fitting new flat-panel displays, improving navigation and safety equipment, and installing a new autopilot system. The first flight of a C-5 with AMP (85-0004) occurred on 21 December 2002

The project funded by Boeing to produce the Boeing Model 248 began in September 1931, with the US Army Air Corps supplying the engines and the instruments. The open cockpit, fixed landing gear, externally braced wing design was the last such design procured by the USAAC as a fighter. The Model 248 had a high landing speed, which caused a number of accidents. To remedy this, flaps were fitted to reduce the landing speed. The Army Air Corps ordered three prototypes, designated XP-936, which first flew on 20 March 1932.
