Like the Naval Air Ferry Command at NAS Terminal Island, the Army's ferrying work was an immense undertaking, thanks to Douglas Aircraft's wartime production. Ground breaking for the initial Douglas Aircraft facility occurred in November 1940, with dedication in October 1941. Douglas had been drawn to Long Beach primarily because of the presence of the town's growing municipal airport and the presence of both the Army and Navy there. With wartime contracts, the company immediately went into intensive production. The company's first C-47 was delivered 16 days after the attack of Pearl Harbor, and another 4,238 were produced during the war. Additionally, the plant turned out some 1,000 A-20 Havocs, not to mention 3,000 B-17 Flying Fortresses and 1,156 A-26 Invaders.
