It was created to help solve aircraft supply issues which the Navy Department faced upon the entry of the U.S. into World War I.
On 27 July 1917 Secretary of the Navy Josephus Daniels approved the construction of the Naval Aircraft Factory as a means for the government to promote industry efficiency, ensure engineering expertise, and to monitor costs.
The increased need for flying boat construction during WWI meant expanding the factory into a final aircraft assembly plant, using civilian subcontractors to supply the components.
The change in focus resulted in the disuse of some production buildings, which were converted into storage depots for unused aircraft.

On 11 March 1942 Admiral Harold Rainsford Stark wrote "It is desired to proceed immediately with the steps necessary to adapt the 'drone' for warfare."
