The Douglas DC-6 was Douglas’ most successful four engine piston airliner.
The DC-6 was developed as a response to a military airlift requirement in World War 2. The C-54 impressed the USAAF and they ordered the development of an improved and larger variant. The designation: YC-112.
By the time the Second World War ended the requirements no longer stood, and therefore Douglas continued to develop the YC-112 as an airliner resulting into the DC-6.
During the Korean War military interest was renewed resulting in the C-118 and USN R6D-1. Witch were built in large numbers. Later these planes found their way too many airlines.
