C-74A Globemaster I

The Douglas C-74 Globemaster was a United States heavy-lift cargo aircraft built by the Douglas Aircraft Company in Long Beach, California. The aircraft was developed after the Japanese attack on Pearl Harbor. The long distances across the Atlantic and, especially, Pacific oceans to combat areas indicated a need for a transoceanic heavy-lift military transport aircraft. Douglas Aircraft Company responded in 1942 with a giant four-engined design. Development and production modifications issues with the aircraft caused the first flight to be delayed until 5 September 1945, and production was limited to 14 aircraft when the production contract was canceled following V-J Day

Design C-74A

The Douglas Aircraft Company began studies at their Santa Monica division in early 1942 for a transport capable of fulfilling the global logistical needs of the U.S. military. Its “C-74 Project Group” used their company’s DC-4 as a basis and concentrated on enlarging its capabilities. The group’s design philosophy was to build a “no-frills” aircraft able to accommodate much of the Army’s large equipment including light tanks, two 105-millimeter (4.1 in) howitzers with their towing vehicles, two angle bulldozers, and smaller utility vehicles. This became the Douglas Model 415 and a cost-plus contract worth more than $50 million was signed 25 June 1942 for 50 aircraft and one static test article. There were no XC- or YC-74 models produced
