Marine Corps Air Station Tustin
Marine Corps Air Station Tustin (IATA: NTK, ICAO: KNTK, FAA LID: NTK) is a former United States Navy and United States Marine Corps air station, located in Tustin, California. History. The Air Station was established in 1942 by the United States Navy as a lighter-than-air base, officially known as Naval Air Station Santa Ana. The base was designed for blimp operations in support of the Navy's coastal patrol efforts during World War II. It was commissioned on 1 October 1942 by its commandant, Capt. Howard N. Coulter. As of July 1947, the  facility, under command of Capt. Benjamin May, had personnel consisting of 100 officers, 500 enlisted men and 180 civilian employees. NAS Santa Ana was decommissioned in 1949. In 1951, the facility was reactivated as Marine Corps Air Facility Santa Ana to support the Korean War. It was the country's first air facility developed solely for helicopter operations. It was renamed Marine Corps Air Station Tustin in 1979. During the Vietnam War, the base was a center for on-going testing of radar installations (including the Sperry TPS-34) which were erected, tested, disassembled and shipped to South Vietnam. It also  was a training facility for helicopter pilots. By the early 1990s, MCAS Tustin was a major center for Marine Corps helicopter aviation and radar on the Pacific Coast. Its primary purpose was to provide support services and material for the 3rd Marine Aircraft Wing and for other units utilizing the base. About 4,500 residents once lived on the base, and the base employed nearly 5,000 military personnel and civilians. In addition to providing military support, MCAS Tustin leased to farmers for commercial crop development. For many years, agricultural lands surrounded the facility. However beginning in the 1980s residential and light  industrial/manufacturing areas developed adjacent to the station. In 1991 and again in 1993, under the authority of the Base Realignment and Closure Act of 1990, it was announced that MCAS Tustin would be closed. Operational closure of the base occurred in July 1999. However, the north hangar is still used as a storage and repair center for commercial blimps. Of the approximately , some (now known collectively as "Tustin Legacy") have been conveyed to the City of Tustin, private developers and public institutions for a combination of residential, commercial, educational, and public recreational and open-space uses. The remaining will  be conveyed to other federal agencies, the City of Tustin and public institutions for the same uses once environmental clean-up operations have been concluded. The site of the base is now the home of the academy of the Orange County Sheriff's Department. Much of the former base has become residential housing. The large blimp hangars have been used for location shooting for numerous movies and TV programs, including JAG and The X-Files. In 1993, the blimp hangars were designated a National Civil Engineering Landmark by the American Society of Civil Engineers (ASCE). There have been talks regarding  making one of the hangars a military museum. The base was featured in "Visiting... with Huell Howser" Episode 1509. Worldwide Aeros Corp is, as of 2013, utilizing one of the historic hangars to build a prototype cargo airship under contract from the Pentagon and NASA. In October, 2013, part of the roof collapsed, damaging the airship prototype. Future. Plans are in the works to convert of the former base into a regional park, to be opened in 2016. As of the summer of 2013, OC Parks is in the process of gathering input from the community in order to determine  the features and layout of the forthcoming facilities. Although the preservation of the hangars is one of the greatest concerns raised in surveys taken by OC Parks, the fate of the south hangar is uncertain. The City of Tustin has reportedly met with officials from the Los Angeles Angels of Anaheim, proposing the former air base as a potential site for a new stadium for the team, whose lease with the City of Anaheim's Angel Stadium allows the team to opt out between 2016 and 2019. In 2016, Orange County and the South Orange County Community College District arranged  for a land swap of ten acres to be used to replace the aging Orange County Animal Shelter in nearby Orange. In July 2016, a ground-breaking ceremony was held.
