The C-5A had the same overall configuration as the C-141, with high wing with a sweep of 25 degrees, four jet engines in pods on underwing pylons, a rear loading ramp, a high tee tail, and main landing gear retracting into fairings. However, it was massively scaled up, with the capability of lifting two main battle tanks or transporting 345 fully-equipped troops. The Galaxy was the largest operational aircraft in the world for 15 years, until it was surpassed by the Soviet Antonov An-124 Condor. The upraised nose cleared the cockpit, permitting the aircraft to be taxied with its nose open. The cockpit was placed at the front of an upper flight deck on top of the huge cargo hold, and accommodated a typical flight crew of six. The upper deck also included a 15-person crew-relief compartment with bunks in front of the wing, and a passenger compartment behind the wing with 73 rearward-facing seats. The C-5A was powered by four General Electric TF39-GE-1 turbofans with 191.3 kN (19,500 kgp / 43,000 lbf) thrust each. Lockheed C-5 Galaxy (wallpaper 1).

All four engines had thrust reversers, and it seems the thrust reversers on the inboard engines could actually be activated while in flight. The aircraft had a four sets of main gear, each with two-axle bogies with two wheels in front and four in the rear, and a four-wheel nose gear. The landing gear could "kneel" to assist in loading cargoes, and featured a system to help land in crosswinds. The C-5A had a boom refueling capability from the start, as well as a computerised "Malfunction Detection, Analysis and Recording (MADAR)" diagnostic system that monitored 800 test points in flight or for ground servicing. The C-5A proved its worth in the fall of 1973, in Operation NICKEL GRASS, the huge airlift to support Israel during the Yom Kippur war, with the big cargolifter carrying massive quantities of ammunition and weapons to assist Israeli forces. The Galaxy also performed reliable service in the last years of the Vietnam War, though one was lost on 4 April 1975 while trying to evacuate orphans from Saigon. 206 of the 382 people aboard were killed, many of them infants. The C-5A's design specifications had been very aggressive and hard to meet. The program did not go smoothly, and in fact the program is said to have coined the term "cost overrun". One of the long-term problems that resulted was that the aircraft did not live up to its fatigue-life specifications, with the wings having barely a quarter of the 30,000-hour lifetime specified. In 1975, Lockheed was awarded a contract to provide new wings to all surviving aircraft to increase the wing service life to the specified 30,000 hours. The first re-winged aircraft was delivered to the USAF in 1983, with the re-winging program complete by July 1987. Lockheed C-5 Galaxy (wallpaper 1).
