Throughout the remainder of the postwar period and until the early 1970s, NAS New York-Floyd Bennett Field primarily functioned as a support base for units of the Naval Air Reserve and the Marine Air Reserve. The airport was also a training facility for reserve squadrons. Until 1970, more than 3,000 reservists in the Navy and Marines trained at Bennett Field every weekend, and 34 aircraft squadrons were constantly being maintained at the field. The field was busiest during the weekends when there were up to 300 daily departures from Bennett Field. The installation also served as a base for units of the New York Air National Guard from 1947 to 1970, when the Air National Guard moved to the Francis S. Gabreski Air National Guard Base on Long Island. Minor adjustments were made to the field through the 1960s in order to accommodate jet aircraft. The Navy also built a trailer park and a school building in the main barracks area during this time. Decommissioning In the aftermath of the Vietnam War in the 1960s, the military was greatly demobilized. By 1970, the Navy was offloading property, including Bennett Field, to pay for the war's expenses. On March 5, 1970, the federal government announced that the Navy would start vacating the airport. Upon the announcement of Bennett Field's decommissioning, Mayor John V. Lindsay asked the federal government for permission to convert the field into a commercial airport. Simultaneously, Governor Nelson Rockefeller proposed a $1.4 billion development on the site. If built, Rockefeller's development would contain a shopping mall, an industrial park, 46,100 housing units, and the potential for 180,000 residents. The governor's proposal had been in planning since November 1969. On April 4, 1970, the Navy conducted its last daily formal inspections of officers, an act that started the process of decommissioning Floyd Bennett Field. NAS New York's tenant squadrons and personnel were transferred to other naval air stations. A Naval Air Reserve Detachment, which supported non-flying units, remained. The Navy itself continued to own the land for two more years. The Naval Air Reserve Detachment would occupy Hangar A until 1983. Meanwhile, the dispute over the possible future uses of Bennett Field continued. In May 1970, the state government released more details of its redevelopment proposal without consulting the city. The next month, Lindsay's administration wrote to the federal government, advocating for Bennett Field to be converted to commercial
