The Naval Aircraft Factory was established by the United States Navy in 1918 in Philadelphia, Pennsylvania. It was created to help solve aircraft supply issues which faced the Navy Department upon the entry of the U.S. into World War I. The US Army’s requirements for an enormous quantity of airplanes created a decided lack of interest among aircraft manufacturers in the Navy's requirements for a comparatively small quantity of aircraft. The Navy Department concluded that it was necessary to build a Navy-owned aircraft factory in order to assure a part of its aircraft supply; to obtain cost data for the department’s guidance in its dealings with private manufacturers; and to have under its own control a factory capable of producing experimental designs.
History
On 27 July 1917, Secretary of the NavyJosephus Daniels approved the project; the contract was let on 6 August 1917 and ground was broken four days later. The entire plant was completed by 28 November 1917, 110 days after ground breaking. When it was completed the greatest need was for patrol flying boats, so production of the H-16 patrol aircraft was started. On 27 March 1918, just 228 days after ground breaking and 151 days from receipt of drawings, the first H-16 built by the NAF was successfully flown. On the following second of April the first two NAF-built H-16s were shipped to the patrol station at RNAS Killingholme, England. After World War I, when the 1922 United States Navy aircraft designation system came into effect, the second letter of the codes designating the manufacturer appropriately specified the latter N for all airframe designs coming from the Naval Aircraft Factory. In 1922, full-scale production of outside designs ended and the NAF began concentrating on the testing and evaluation of aircraft, including both the modification to outside types and all-new in-house designs. Successful designs were then turned over to industry for production. The changein focus resulted in the disuse of some production buildings, which were converted into storage depots for unused aircraft. In 1922-1923, the NAF fabricated the USS Shenandoah, although final assembly took place at Naval Air Station Lakehurst, New Jersey, where the only hangar in the United States large enough to house the airship was located. In the 1934, under the Vinson-Trammell Act, it was decided that the Navy would build 10 per cent of its own aircraft to stay abreast of modern manufacturing techniques and costs. The NAF thus resumed large-scale aircraft production in 1936 on introduction of the N3Nbiplanetrainer aircraft. The NAF ended aircraft production with the end of World War II in 1945. The existence of the Naval Aircraft Factory was controversial at times, as it put a federally funded industrial activity in direct competition with civilian industry, and this was one of the reasons it was disestablished. Upon disestablishment, the aircraft test functions were passed to the newly formed Naval Air Test Center at Naval Air Station Patuxent River, Maryland. Located at the Philadelphia Naval Shipyard, on League Island, the main construction building still exists, but was converted for use by the Naval Surface Warfare Center Carderock Division, as a facility for research and development.
