Tustin Marine Corps Air Station, located in Tustin, California, was established in 1942. It served as a military airfield primarily for the United States Marine Corps, supporting various aviation operations and training missions. The base was known for its distinctive blimp hangars, which were used during World War II for airship operations. The air station was officially closed in 1999 as part of a broader military downsizing. Today, the site has been repurposed for civilian use, with plans for residential and commercial development. The historic hangars remain a notable landmark, reflecting the area's military heritage and history.
