AN/FPS-129

AN/FPS-129 “Have Stare” (later renamed to “Globus Ⅱ”) is operating in X-Band early-warning, mechanical tracking radar. The radar was originally designed to collect intelligence data against ballistic missiles, with aerodynamic and satellite tracking as secondary missions.

The antenna is housed in a 35 m diameter radome. It is of Cassegrain type with the main dish diameter of 27 m. The sub-reflector has a diameter of 3.15 m.

The radar became operational in 1995 at Vandenberg Air Force base in California. In late 1998, the radar was dismantled and moved to Vardø. It became operational in about 2003.
