Lockheed Martin C-5M Super Galaxy [1:1]

"As the Air Force’s largest and only strategic airlifter, the C-5 Galaxy can carry more cargo farther distances than any other aircraft. With a payload of six Mine Resistant Ambush Protected vehicles (MRAPs) or up to five helicopters, the C-5 can haul twice as much cargo as any other airlifter."

Following a study showing that 80% of the C-5 airframe's service life was remaining, 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 Reliability Enhancement and Re-engining Program (RERP) began in 2006. It includes fitting new General Electric F138-GE-100 (CF6-80C2) engines, pylons and auxiliary power units, and upgrades to aircraft skin and frame, landing gear, cockpit and pressurization systems. Each CF6 engine produces 22% more thrust (50,000 lbf or 220 kN), providing a 30% shorter takeoff, a 38% higher climb rate to initial altitude, an increased cargo load and a longer range. Upgraded C-5s are designated C-5M Super Galaxy.
