About: Onizuka Air Force Station

Onizuka Air Force Station or Onizuka AFS was a United States Air Force installation in Sunnyvale, California, at the intersection of State Route 237 and North Mathilda Avenue. It was operational from 1960 to 2010. Its distinguishing feature was Building 1003, known locally as the Blue Cube or simply the "Cube" given its size, color, and lack of windows. The station's other distinguishing features were its three primary parabolic dish antennas used for communication with remote tracking stations used to control military satellites; these antennas were named Sun East, Sun West, and Sun 3.
