The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service before 1962, after which all U.S. Navy variants were also designated as the C-118.
