When the An-225 Mriya was destroyed in 2022, the world lost its single largest aircraft. But the West still keeps a giant of its own in the air \u2014 one that has been hauling tanks, helicopters and satellites around the planet since before the Moon landings, and is scheduled to keep doing it into the 2040s. It is the Lockheed C-5, and in its modern form it is called the Super Galaxy.<\/em><\/p>\n\n

A cathedral with wings<\/h2>\n

Numbers only get you so far with the Galaxy, so try this one: its cargo hold is around 37 metres long \u2014 longer than the entire distance the Wright brothers covered on their first powered flight. You do not load a C-5 so much as drive into it. The nose hinges upward like a giant visor and a ramp drops at the tail, so vehicles can be driven straight through from front to back. Inside, it can swallow two M1 Abrams main battle tanks<\/strong>, six attack helicopters, or outsize loads that fit in nothing else in the American inventory. It rolls on a 28-wheel main landing gear that can “kneel” to bring the floor closer to the ground.<\/p>\n

With a wingspan of 67.9 metres<\/strong> and a maximum take-off weight of 840,000 lb (around 381 tonnes)<\/strong>, the C-5 is one of the largest military aircraft ever built \u2014 second in the West only to the giant Antonovs it was often mentioned alongside.<\/p>\n

Born in the 1960s<\/h2>\n

The Galaxy came out of the US Air Force's CX-HLS<\/strong> heavy-lift requirement of the 1960s \u2014 the same programme whose losing airliner concept helped shape the Boeing 747. Lockheed won the military contract, and the first C-5A rolled out in 1968 and made its maiden flight on 30 June 1968<\/strong>. It entered service in 1970 and went straight to work supporting operations in Vietnam, then spent the Cold War as America's strategic-airlift muscle: the aircraft that could put an army's worth of heavy equipment on another continent in days.<\/p>\n

The Super Galaxy upgrade<\/h2>\n

By the 2000s the airframes were sound but the systems and engines were dated. Rather than retire the fleet, the Air Force rebuilt it. The C-5M Super Galaxy<\/strong> programme fitted new General Electric F138 (CF6-derived) engines<\/strong> \u2014 each producing about 50,000 lb of thrust, roughly 22% more than the originals \u2014 along with modernised avionics, cockpit and dozens of other systems. The payoff was dramatic: about a 30% shorter take-off roll<\/strong> and a far steeper climb, letting the fully loaded giant get airborne from shorter runways and reach altitude faster. Every one of the surviving aircraft \u2014 49 C-5Bs, 2 C-5Cs and one C-5A \u2014 had been converted to C-5M standard by August 2018<\/strong>.<\/p>\n

Still flying<\/h2>\n

Today the Super Galaxy remains a backbone of US global reach, moving outsize cargo from hubs such as Ramstein Air Base in Germany to wherever it is needed. With the modernisation, the type is projected to serve into the 2040s \u2014 meaning some C-5 airframes will have flown for the better part of eighty years.<\/p>\n
