Naval Air Station Glenview or NAS Glenview was an operational U.S. Naval Air Station from 1937 to 1995. Located in Glenview, Illinois, a suburb of Chicago, the air base primarily operated training aircraft as well as seaplanes on nearby Lake Michigan during World War II. Reconfigured as a Naval Air Reserve base following World War II, NAS Glenview supported Naval Air Reserve, Marine Air Reserve/4th Marine Aircraft Wing, and U.S. Army Reserve 244th Aviation Group as well as an active duty Coast Guard Air Station.

The base was originally built by the Curtiss Flying Service and intended to be the hub of Chicago's air service. When the field was dedicated as Curtiss Field on 20 October 1929, it was home to the largest hangar built to that time, Hangar One. Hangar One, one of the most advanced hangars at the time, included many innovations which were considered state-of-the-art in its time. A one gigacandela electric light was erected which allowed for airfield activity in the dark. A system of carefully designed sliding doors created dividers for storage and zone heating. Glassed-in galleries allowed passengers the opportunity to watch the mechanics at work on the ground floor. A passenger-friendly restaurant and lounge were opened in the upper levels. A loudspeaker system informed the passengers of the flight arrivals and departures. The final cost for the airfield and Hangar One was $3 million in 1930. By adjusting the price for inflation, the relative cost in 2017 would equate to about $44.8 million. It was widely believed to be one of the Midwest's finest airports.

In 1930, the National Air Races took place at Curtiss-Reynolds Airport/Curtiss Field and in 1933 the International Air Races took place there in conjunction with the Century of Progress. Such aviation luminaries as Charles Lindbergh, Wiley Post, Jimmy Doolittle and Art Chester attended. In 1934, Post tried to set an aviation altitude record from Curtiss. By 1938, civilian and military operations both operated from the field, but in 1940 it was sold to the United States Navy.

Reduced military budgets between World War I and World War II forced the War Department and the Navy Department to place increased emphasis on Reserve and National Guard manpower, with many of the facilities for the personnel of these organizations located in major metropolitan areas, given their status as centers of civilian employment. One course pursued by the U.S. Navy was to establish a series of Naval Reserve Air Bases (NRABs), the third one of which was established near Chicago adjacent to the then-Naval Training Station Great Lakes. Reservists initially flew and maintained seaplanes from shore facilities on Lake Michigan and a small field at Naval Training Station Great Lakes. These facilities eventually became inadequate for newer and larger aircraft entering the Fleet in the 1930s, and it was recommended that the NRAB be relocated to Curtiss-Reynolds Airport/Curtiss Field. This recommendation was approved and military construction at Curtiss Field began on 4 January 1937, followed by an official dedication as NRAB Chicago on 28 August 1937.

For the next three years, the air station's primary role was elimination training for students seeking appointments as Naval Aviation Cadets (NAVCADs). Those students meeting the required standards were later transferred to NAS Pensacola, Florida for further flight training. By 1941, with the United States' entry into World War II appearing imminent, it was apparent to the naval leadership in Washington DC that the primary flight training facilities concentrated at and around NAS Pensacola would not be able to accommodate the needed expansion in Naval Aviation. As a result, naval planners opted to transfer primary flight training to multiple Naval Reserve Air Bases around the country and use NAS Pensacola for advanced training. NRAB Chicago was selected to be the first base in this program as a proof of concept. A subsequent construction program of 121 work days resulted in 1,300,000 square feet (120,000 m²) of new concrete being poured for runways, taxiways and ramps, while new hangars and other administrative and support buildings were also constructed and completed by late November 1942. On 1 January 1943, NRAB Chicago was redesignated as NAS Chicago. By 1944, "Chicago" was deleted from the air station's title and the installation renamed NAS Glenview.

Nearly 9,000 aviation cadets for the U.S. Navy, U.S. Marine Corps and U.S. Coast Guard received their primary flight training at NAS Glenview during World War II, which represented over 800,000 flight hours and over 2 million takeoffs and landings. Later during the war, NAS Glenview also hosted advanced training in Fleet combat aircraft, primarily for carrier qualification in Lake Michigan aboard the Chicago-homeported training aircraft carriers USS Sable (IX-81) and USS Wolverine (IX-64) of the 9th Naval District Carrier Qualification Training Unit (CQTU).^{[citation needed]}

Following the end of World War II, NAS Glenview discontinued its role as a primary training base and became headquarters for the newly formed Naval Air Reserve Training Command (NAVAIRESTRACOM) in 1946. NAVAIRESTRACOM's primary responsibility was the oversight of numerous reserve naval air stations throughout the US where experienced Naval Aviators, enlisted Naval Aircrewmen, and maintenance personnel from World War II could affiliate as Naval Reservists and maintain their aviation proficiency should their skills be needed for future conflicts. These skills were readily proven when squadrons and personnel were mobilized and recalled back to active duty during the Korean War and the Berlin Crisis. Each base also had an assigned Naval Air Reserve Training Unit (NARTU), which until a reorganization of the Naval Air Reserve in 1970, actually "owned" all assigned aircraft. One of the better units based at NAS Glenview in the post-World War II period was Attack Squadron 725 (VA-725), part of NARTU Glenview until 1970, when it was redesignated as Attack Squadron 209 (VA-209) and became part of Carrier Air Wing Reserve TWENTY (CVWR-20) from 1970 to 1972. Initially flying the A-4B Skyhawk, the squadron later transitioned to the A-4L Skyhawk. From 1967 to 1972, part of VA-725-cum-VA-209 also operated as the Air Barons, a Naval Air Reserve precision flight demonstration team that augmented the U.S. Navy Flight Demonstration Squadron, the Blue Angels, and the U.S. Air Force's demonstration squadron, the Thunderbirds, at air show locations other than those where the Blue Angels or Thunderbirds were performing on a given weekend during the air show season. Both VA-209 and the Air Barons were disestablished in 1972.

During the latter half of the Cold War from 1970 until 1990, and continuing on from the post-Cold War period until 1995, NAS Glenview was primarily the home of two Naval Air Reserve patrol squadrons, Patrol Squadron SIXTY (VP-60) and Patrol Squadron NINETY (VP-90). Initially equipped with the P-2 Neptune, both later transitioned to the P-3A Orion, followed by another transition the P-3B Orion maritime patrol and reconnaissance aircraft. These aircraft were home based at NAS Glenview and manned by a combination of full-time active duty Training and Administration of the Reserve (TAR) personnel and part-time Selected Naval Reservists (SELRES). Training activities were conducted from NAS Glenview and the patrol squadrons routinely deployed overseas for anti-submarine warfare operations against Soviet submarines and surface ships in the Atlantic and Mediterranean or for other operations in the Caribbean.
