Question: Naval Aviation Depot Alameda is a former United States Navy aviation depot which was located at Naval Air Station Alameda, was a United States Navy Naval Air Station, in Alameda, California, on San Francisco Bay, closed in which year?
Context: The Grand Prairie Armed Forces Reserve Complex (formerly Naval Air Station Dallas or Hensley Field) is a former United States Navy Naval Air Station located on Mountain Creek Lake in southwest Dallas.  The installation was originally established as an Army Aviation center, and eventually became home to aviation assets from all the military services.  The facility was decommissioned as a naval air station in December 1998 pursuant to BRAC action and the extant Naval Air Reserve, Marine Air Reserve and Texas Air National Guard flying units (wings, groups, squadrons) relocating to the nearby former Carswell AFB, which was concurrently transferred to U.S. Navy custody via the Base Realignment and Closure Commission action and renamed Naval Air Station Joint Reserve Base Fort Worth / Carswell Field. Naval Aviation Depot Pensacola is a former United States Navy aviation depot which was located at Naval Air Station Pensacola, Florida, until it was closed by the 1993 Base Realignment and Closure Commission. Naval Air Station Sanford (IATA: NRJ, ICAO: KNRJ, FAA LID: NRJ) was a United States Navy naval air station in Sanford, Florida, approximately 20 miles north of Orlando, Florida.  Opening less than a year after the start of World War II, NAS Sanford's initial function was as an advanced training base for land-based patrol bombers, followed by carrier-based fighter aircraft.  The air station briefly closed following the war and was placed in caretaker status, then reactivated in 1950, eventually serving as a Master Jet Base for carrier-based heavy attack and reconnaissance aircraft until 1969.  After its closure, it reopened as civilian general aviation airport under various names with a non-Navy civilian airport identifier (IATA: SFB, ICAO: KSFB, FAA LID: SFB) until finally transitioning to a scheduled air carrier airport under its current name of Orlando-Sanford International Airport. Alameda Point is the name given to the lands of the former Naval Air Station Alameda in the City of Alameda, California.  Alameda Point consists of 1560 acre of land area at the western end of the island of Alameda.  Most of the land was reclaimed from the San Francisco Bay. The Indian Navy currently operates twenty-one air squadrons. Of these, ten operate fixed-wing aircraft, eight are helicopter squadrons and the remaining three are equipped with unmanned aerial vehicles (UAV).  Building on the legacy inherited from the Royal Navy prior to Indian independence, the concept of naval aviation in India started with the establishment of Directorate of Naval Aviation at Naval Headquarters (NHQ) in early 1948.  Later that year officers and sailors from the Indian Navy were sent to Britain for pilot training.  In 1951, the Fleet Requirement Unit (FRU) was formed to meet the aviation requirements of the navy.  On 1 January 1953, the charge of Cochin airfield was handed over to the navy from the Directorate General of Civil Aviation.  On 11 March, the FRU was commissioned at Cochin with ten newly acquired Sealand aircraft.  The navy's first air station, INS "Garuda", was commissioned two months later.  From February 1955 to December 1958, ten Firefly aircraft were acquired.  To meet the training requirements of the pilots, the indigenously developed HAL HT-2 trainer was inducted into the FRU.  On 17 January 1959, the FRU was commissioned as Indian Naval Air Squadron (INAS) 550, to be the first Indian naval air squadron.  In the following two years, three more naval air squadrons—INAS 300, INAS 310 and INAS 551—were commissioned.  The first two operated from the newly purchased aircraft carrier INS "Vikrant" flying Sea Hawks and Alizés, whereas the latter one, equipped with Vampires, was used for training purposes. Naval Air Station Alameda (NAS Alameda) was a United States Navy Naval Air Station in Alameda, California, on San Francisco Bay. Naval Aviation Depot Norfolk is a former United States Navy aviation depot which was located at Naval Air Station Norfolk until it was closed by the 1993 Base Realignment and Closure Commission. Naval Air Station Port Lyautey is a former United States Navy Naval Air Station in Morocco, about 5 km north-northwest of Kenitra and about 120 km northeast of Casablanca.  The Naval Air Station was turned over to the Royal Moroccan Air Force and the last of US military personnel departed the base in 1977.  The airport was later reopened as Kenitra Airport after it was closed. Alameda Island is an island in the San Francisco Bay in California.  It is south and west of, and adjacent to Oakland, and across the bay eastward from San Francisco.  Located on the island is most of the city of Alameda, a city in Alameda County.  Also located on the island is the Naval Air Station Alameda, a defunct naval air station, as well as a small uninhabited part of San Francisco.  The island was originally a peninsula and a part of Oakland, and is now separated from the mainland by the Oakland Estuary.  The island is connected to the mainland by four bridges: the Park Street Bridge, Fruitvale Bridge, High Street Bridge, and Bay Farm Island Bridge.  The Posey and Webster Street tubes also connect Oakland to Alameda Island.
