C-118 Liftmaster
The C-118 Liftmaster was a long-range military transport aircraft developed by the American firm Douglas, based on the civilian DC-6 transport aircraft. Alongside civilian DC-6 production, 166 aircraft were built for the U.S. Air Force and U.S. Navy. The aircraft belonging to the Air Force were designated C-118A.
Presidential and VIP Service
The twenty-ninth DC-6 produced became President Truman’s personal aircraft. This was the VC-118 Independence, which featured a cabin for 24 passengers, or 12 berths for rest during night flights, and a workspace.
Military Designations and Wider Adoption
For the U.S. Navy, 61 R6D-1 aircraft and four R6D-1Z variants with VIP cabins were in operation. In 1962, their designations changed to C-118B and VC-118B, respectively. Other military services also ordered DC-6 aircraft, most of which had previously served as civilian models.
