Merced Castle Airport is more than just an air gateway; it is a piece of living aviation history in California. Located on the site of the former Castle Air Force Base, which closed in 1995, this airport has retained its monumental scale and special atmosphere. It was named in honour of Brigadier General Frederick Castle, a World War II hero, adding a touch of valour to its legacy. Today, Castle serves as a vital hub for general aviation and is a key economic asset for Merced County, boasting one of the longest runways in the region.

The main feature of Castle Airport is its multifunctionality and immense potential. Thanks to its robust infrastructure inherited from the military, the airport is capable of accepting almost any type of aircraft, from small private jets to large cargo planes. This makes it an attractive venue for private and corporate aviation, as well as for hosting various aviation events. Another unique asset located right on its grounds is the Castle Air Museum, which displays over 80 restored aircraft from World War II, the Korean War, and the Cold War, making a visit to the airport interesting even for those not planning to fly. The airport is also being considered as a potential location for a heavy maintenance facility for the California High-Speed Rail.
