The Naval Reserve Flying Corps (NRFC) was the first United States Navy reserve pilot procurement program. As part of demobilization following World War I the NRFC was completely inactive by 1922; but it is remembered as the origin of the naval aviation component of the United States Navy Reserve, the Naval Air Reserve.
United States naval aviation inventory was six airplanes at the beginning of World War I. Four operated from Naval Air Station Pensacola and two were assigned to USS North Carolina. The Navy organized an unfunded naval militia in 1915 encouraging formation of ten state-run militia units of aviation enthusiasts. The Naval Appropriations Act of 29 August 1916 included funds for both a Naval Flying Corps (NFC) and a Naval Reserve Flying Corps. Students at several Ivy League colleges organized flying units and began pilot training at their own expense. The NFC mustered 42 Navy officers, 6 United States Marine Corps officers, and 239 enlisted men when the United States declared war on 6 April 1917. These men recruited and organized qualified members from the various state naval militia and college flying units into the NRFC.
A three-part pilot training program was implemented beginning with two months of ground school, followed by preliminary flight training teaching student pilots to fly solo, and advanced flight training to qualification as a naval aviator with a commission in the Naval Reserve Flying Corps. The first ground school for pilot training was at the Massachusetts Institute of Technology. The first class of fifty student pilots arrived on 23 July 1917 for an eight-week program covering electricity, signals, photography, seamanship, navigation, gunnery, aeronautic engines, theory of flight, and aircraft instruments. Later classes received an initial period of indoctrination and preliminary training aboard a receiving ship before assignment to ground school. Those who successfully completed ground school were transferred to naval air stations for flight training. In July 1918 parallel ground school programs began at the University of Washington in Seattle and at Dunwoody Institute in Minneapolis; but few graduates of these schools could be counted among the 18,000 naval aviation personnel who reached Europe before the war ended.
