Closure of Onizuka Air Force Station
Onizuka Air Force Station, located in Sunnyvale, was officially closed in 2014. Known colloquially as 'The Blue Cube', Onizuka AFS was once a central part of U.S. military satellite operations. Its closure marked the end of an era in military history for Sunnyvale, as the base had been a significant site for satellite command and control operations for several decades. The event represented a pivotal moment in the city's transition away from military operations.
