We provide an incredible array of expertise in critical technical disciplines. Our efforts help ensure the rapid development and training of the most respected Air Force in the world.

On the big screen

Over the years, the ranges and bases that we support, as well as the adjacent cities where we live, have been featured in numerous feature-length films.
In 1950, the Naval Air Station (NAS) Point Mugu, was the setting for the Cold War era drama, The Flying Missile. The comedic Western, North to Alaska, starring John Wayne, was also filmed at Point Mugu in the early ‘60s. In 2000, NAS Point Mugu merged with two other Navy operating facilities to create the Naval Base Ventura County (NBVC).
Top Gun: Maverick, a 2021 action drama that is the sequel to the 1986 Tom Cruise classic, Top Gun, was filmed at the Naval Air Weapons Station (NAWS) China Lake, the Navy’s largest single landholding. The Naval Air Warfare Center Weapons Division (NAWCWD) is the primary tenant at NAWS China Lake.
The Morton Salt company takes refuge along Interstate 80, nestled between the North and South Ranges of the Utah Test and Training Range where vast amounts of salt are mined from the Great Salt Lake and make their way onto tabletops or on roadways during the wintery weather months. This unique, bizarre scenery has captured the attention and built on the imaginations of film producers and directors. The location has been used in a number of films such as Pirates of the Caribbean, Independence Day, Con Air, Tree of Life and Top Gear.
