Being on the heels of the smaller C-130 Hercules, Lockheed’s C-5 Galaxy was America’s premier oversized military transport, and it remains the country’s largest military cargo plane. The C-5 Galaxy has the largest cargo hold of any military transport in service with the United States Air Force USAF. Its four General Electric engines can routinely haul a 127-ton payload for about 7,000 miles without refueling.
The C-5 Galaxy has supported several military operations and humanitarian airlifts worldwide. It was involved in the massive army airlift to Israel during the Yom Kippur War, and upgraded versions of the airplane designated C-5M Super Galaxy are expected to remain in the service of the USAF until 2040.
The press derided the C-5 Galaxy as an expensive “white elephant” until its outstanding performance during Operation Nickel Grass. It carried almost half the total cargo delivered in 145 of the 547 total flight missions.
The C-5 Galaxy was one of the largest aircraft ever made.
