Lockheed’s Advanced Aeronautics and Basic Science divisions developed the 370-acre Rye Canyon research facility in Santa Clarita in the late 1970s, where labs, wind tunnels, and anechoic chambers helped develop stealth technology programs like the F-117 stealth fighter/bomber. The layout of the campus was designed by William Pereira, who designed other aerospace campuses in Southern California, defining a kind of regional Space Age modernism. Lockheed mostly vacated the site in the early 1990s, after moving Skunk Works to Palmdale, and Rye Canyon has been reoccupied by other companies, and heavily used by the entertainment industry as a filming location and production center.
