This facility, next to the 405 freeway, makes radar systems for aviation and defense, including electronic warfare, air traffic control, and tactical radar systems primarily for the Navy. Operated for many years by ITT, the plant is now owned and operated by L3Harris, the nation’s sixth largest defense contractor, which specializes in communication, surveillance, reconnaissance and intelligence technologies, using radar, satellites, and other electronic systems. The company employs more than 3,000 people in Southern California, at a dozen or so primary locations.
