Liftmaster (DC-6)

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, it was reworked after the war to compete with the Lockheed Constellation in the long-range commercial transport market. More than 700 were built and many still fly today 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 prior to 1962, after which all U.S. Navy variants were also designated as the C-118.

Operational use

The United States Army Air Forces commissioned the DC-6 project as the XC-112 in 1944. The Army Air Forces wanted a lengthened, pressurized version of the DC-4-based C-54 Skymaster transport with more powerful engines. By the time the prototype XC-112A flew on 15 February 1946, the war was over, the USAAF had rescinded its requirement, and the aircraft was converted to YC-112A, being sold in 1955 Douglas Aircraft modified the design into a civil transport 80 in (200 cm) longer than the DC-4. The civil DC-6 first flew on 29 June 1946, being retained by Douglas for testing. The first airline deliveries were to American Airlines and United Airlines on 24 November 1946

  • Current operators

    Today, most DC-6s are inactive, stored, or preserved in museums. A number of DC-6s are still flying in northern bush operations in Alaska and Canada, while several are based in Europe and a few are still in operation for small carriers in South America.

    • One DC-6A, G-APSA, is based in the UK and available for private charter. It was painted in British Eagle colours and appeared at many air displays. Apparently this was scrapped in 2018. It had been grounded at Coventry for some time due to wing spar issues and these proved beyond economic repair. 
    • One DC-6B is in use by Red Bull in Salzburg, Austria.[13]
    • One DC-6B V5-NCG “Bateleur” was in use with Namibia Commercial Aviation. This was the last DC-6 off the Douglas production line and the last DC-6 in the world in passenger configuration still flying commercially. This aircraft was also used by software company PMDG as the basis for their simulated DC-6 for consumer flight simulators.
    • As of July 2016, Everts Air Cargo in Alaska operates eleven DC-6s and two C-46s, with several more in storage.[15] Their sister company Everts Air Fuel operates three DC-6 and two C-46.
    • As of January 2007, The nose section of DC-6 cn 43128 was transported to Finland and has been restored to its original state. BCPA, TEAL, Pacific Western and others operated this airliner.

Douglas DC-6/C-118 Liftmaster

The military version, similar to the DC-6A, was the USAF C-118 Liftmaster; the USN R6D version used the more powerful R-2800-CB-17 engines. These were later used on the commercial DC-6B to allow international flights. The R6D Navy version (in the late 1950s and early 1960s) had Curtiss Electric constant-speed reversing propellers.

The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
