Summary
| Description |
English: DR-1, one of 3 antennas of the AN/FPS-50 surveillance radar of the US Air Force Ballistic Missile Early Warning System (BMEWS) site II at Clear, Alaska. Built in 1961 in the Cold War and closed in 2001, BMEWS was an arctic-based system of radars and computers to detect a nuclear ICBM attack on the US from Russia over the North Pole. It's extreme northern location was designed to give an early enough warning (15 - 30 minutes) that US missiles could be launched and bombers could take off, reducing the chance of a preemptive nuclear strike on the US.
The original photo's description was: View of south side of radar scanner building no. 104 showing personnel exit door at side building, showing DR 1 antenna from oblique angle on foundation berm with DR 2 and DR 3 antennae in background. - Clear Air Force Station, Ballistic Missile Early Warning System Site II, One mile west of mile marker 293.5 on Parks Highway, 5 miles southwest of Anderson, Anderson, Denali Borough, AK |
