, 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.

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.

Future

Plans are in the works to convert of the former base into a regional park, originally scheduled to be opened in 2016. In the summer of 2013, OC Parks was 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 allowed 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.
