Douglas became closely associated with transport aircraft because the DC-3 reshaped commercial airline economics and its military derivatives, including the C-47 and C-53, became wartime and postwar workhorses. The company also built large wartime capacity beyond Santa Monica, including the Long Beach plant opened for World War II production.
For defense catalog purposes, Douglas is especially relevant as the manufacturer of the A-4 Skyhawk and the C-47 Skytrain. The A-4 connected Douglas's postwar carrier-attack design work to a long export and training life, while the C-47 tied the company to military airlift, airborne operations, medical evacuation, and later special-mission adaptations.

Douglas Aircraft Company was independent from 1921 until the 1967 McDonnell merger. Later Douglas-origin programs may appear under McDonnell Douglas or Boeing sources depending on date and corporate custody.
