Lockheed C-5 Galaxy

The Lockheed C-5 Galaxy is one of the largest military aircraft ever built, designed to give the United States Air Force a true strategic heavy-lift capability. The first version, the C-5A, began flight testing in 1968. With a length of roughly 247 feet and a wingspan of about 222 feet, the Galaxy dwarfed earlier transports and could carry payloads in the range of 265,000 pounds.

The C-5 was built to move outsized and oversized cargo that smaller aircraft could not accommodate, including main battle tanks, helicopters, and heavy engineering equipment. Nose and aft doors allow vehicles to be driven straight through the cavernous cargo hold, enabling rapid loading and unloading. Powered by four large turbofan engines, it could deliver this cargo across oceans without refueling stops, transforming the scale and speed of American power projection.

Despite early technical and cost controversies, the Galaxy proved enduring. It served in major airlift operations from the Vietnam era onward and was later modernized, with upgraded engines and avionics in the C-5M Super Galaxy configuration extending the type's service life well into the twenty-first century.
