Google does not own Moffett Field. The site, between Mountain View and Sunnyvale, is on federal property controlled by NASA.
In 2014, Google subsidiary Planetary Ventures LLC entered into a 60-year lease on a 1,000 acre portion of the NASA Ames Research Center site that includes Moffett Federal Air Base, the three large aircraft hangars, and golf course. The corporation assumed responsibility for operating and maintaining the site and agreed to renovate and improve the site’s distinctive hangar buildings. Google is using the facilities to support its research and development and technology innovation activities.
