Pre-war[edit]

The company is most famous for the "DC" ("Douglas Commercial") series of commercial aircraft, including what is often regarded as the most significant transport aircraft ever made: the Douglas DC-3, which was also produced as a military transport known as the C-47 Skytrain or "Dakota" in British service. Many Douglas aircraft had long service lives.

Douglas Aircraft designed and built a wide variety of aircraft for the U.S. military, including the Navy, Army Air Forces, Marine Corps, Air Force, and Coast Guard.

The company initially built torpedo bombers for the U.S. Navy, but it developed a number of different versions of these aircraft, including reconnaissance planes and airmail aircraft. Within five years, the company was building about 100 aircraft annually. Among the early employees at Douglas were Ed Heinemann, "Dutch" Kindelberger, and Jack Northrop, who later founded the Northrop Corporation.^[12]

The company retained its military market and expanded into amphibian airplanes in the late 1920s, also moving its facilities to Clover Field at Santa Monica, California. The Santa Monica complex was so large, the mail girls used roller skates to deliver the intracompany mail. By the end of World War II, Douglas had facilities at Santa Monica, El Segundo, Long Beach, and Torrance, California, Tulsa and Midwest City, Oklahoma, and Chicago, Illinois.^[13]
