The Lockheed C-5A/B Galaxy is the largest USAF aircraft and is a conventional high-wing, T-tailed transport aircraft. The C-5A made his maiden flight on June 30, 1968, and the first operational C-5A reached Military Airlift Command on December 17, 1969 and the last was delivered in May 1973.
Delivery of the upgraded C-5A, the new built C-5B version began in January 1985. The C-5B is the upgraded version with strengthened wings and an in-flight-refueling receptacle, introducing improved automated flight control system and a malfunction detection and analysis and recording system. The C-5’s have a 28 wheel main undercarriage.
The C-5A/B Galaxy mission profile:
the C-5A/B always seats 73 personnel in rearward-facing airline-style seats in the upper aft deck, located above the main cargo compartment. If they using palletized seats in its cargo compartment there is place for another 290 passengers.
typical loads include two M1A1 Abrams main battle tanks.
one M1A1 Abrams and two M2 Bradley fighting vehicles.
four M551 Sheridan light tanks plus one tactical vehicle.
sixteen 3/4 ton trucks.
ten LAV-25’s light armored vehicles.
four Boeing AH-64D Apache attack-helicopters.
the C-5A/B is not usually employed for airborne operations but some crews are qualified, the rear loading ramp is capable of opening in flight to drop 338 paratroopers, or four Sheridan tanks or a combination of these.
A total of 131 C-5s have been built. The first 81 were C-5A models built in the late 1960’s and early 1970’s. In the 1980s, production resumed, and 50 new Galaxy’s designated C-5Bs, were built with some modest improvements. Two of the original C-5A’s, designated C-5C’s, were specially modified to carry spacecraft pieces that need to be transported quickly. Some unofficial sources claim this modification also enables the C-5C to be used for covert transportation of classified material between Lockheed’s Skunk Works in California and the test center at Groom Lake, Nevada, also known as Area 51. Lockheed and the U.S. government will neither confirm nor deny the authenticity of this speculation. Today, there are 125 C-5’s left: 74 A models, 50 B’s, and two C’s.
From 2005 the USAF is modernizing its C-5A and C-5B’s through the Aviation Modernization Program (AMP) and Reliability Enhancement and Re-engine Program (RERP). AMP take care of the electronics and will improve flight safety and navigation equipment. RERP will replace the four General Electric TF39-GE-1C turbofans by four General Electric F138-GE-100 engines. 112 C-5A, B and C’s will be reworked during these programs, the first C-5M Galaxy is the 86-0013.
