O Galáxia Lockheed C-5 é uma grande aeronave de transporte militar originalmente projetada e construída pela Lockheed, e agora mantida e atualizada por seu sucessor, Lockheed Martin. Ele fornece à Força Aérea dos Estados Unidos (USAF) uma pesada capacidade de transporte aéreo estratégico de alcance intercontinental, que pode realizar cargas superdimensionadas e superdimensionadas, incluindo todas as cargas certificadas pelo ar. A Galáxia tem muitas semelhanças com seu antecessor Lockheed C-141 Starlifter menor, e o mais tarde Boeing C-17 Globemaster III. O C-5 está entre as maiores aeronaves militares do mundo.
The Lockheed C-5 Galaxy is one of the largest military transport aircraft ever built, designed to provide the United States Air Force (USAF) with heavy strategic intercontinental airlift capability. The C-5B variant, introduced in the mid-1980s, was an upgraded version of the original C-5A. It incorporated all the improvements and modifications developed for the C-5A, including enhanced wing structures and updated avionics, but was built using more reliable, modern manufacturing techniques. The C-5B can carry virtually any U.S. military-certified air-transportable equipment, including two M1 Abrams main battle tanks, or a massive amount of cargo and personnel over global distances. It is characterized by its signature high wing, T-tail, and clam-shell doors at both the nose and tail for roll-on/roll-off loading.
