The
Curtiss C-46 Commando is a transport aircraft derived from the Curtiss CW-20 pressurised high-altitude airliner design. Early press reports used the name 'Condor III' but the Commando name was in use by early 1942 in company publicity. It was used as a military transport during
World War II by the
United States Army Air Forces and also the
U.S. Navy/
Marine Corps, which used the designation
R5C. The C-46 served a similar role to its counterpart, the
Douglas C-47 Skytrain, but was not as extensively produced. At the time of its production, the C-46 was the largest twin-engine aircraft in the world, and was the largest and heaviest twin-engine aircraft to see service in World War II.After World War II, a few surplus C-46 aircraft were briefly used in their originally designated role as passenger airliners, but the glut of surplus C-47s dominated the marketplace and the C-46 were soon relegated to primarily cargo duty. The type continued in U. S. Air Force service in a secondary role until 1968. However, the C-46 continues in operation as a rugged cargo transport for Arctic and remote locations with its service life extended into the 21st century.
