The Lockheed C-5 Galaxy is a large military strategic airlifter that entered United States Air Force service in 1970, designed to carry oversized cargo such as tanks and helicopters over intercontinental distances through nose and tail cargo doors that allow drive through loading. Across upgraded variants it has remained among the largest military aircraft in the world and a core component of American strategic airlift capacity for decades.

Why was the early C-5 Galaxy fleet restricted, and how was the problem fixed?
Wing cracks limited the early fleet to 80 percent of design loads until the H-Mod re-wing program, which fitted new wings from 1980 to 1987.
Cracks were noticed in the wings of several aircraft during static and fatigue testing, and the C-5A fleet was restricted to 80 percent of maximum design loads as a result. Load alleviation systems were added to reduce wing loading, and by 1980 payloads were restricted to as low as 50,000 pounds for general cargo in peacetime operations. A program known as H-Mod, begun in 1976, re-winged the 76 completed C-5As to restore full payload capability and service life, with the new wings fitted from 1980 to 1987.
