Bethel, Alaska
A radar site was initially activated in September 1951 at Bethel, Alaska, manned by Federalized Alaska Air National Guardsmen and equipped with a World War II AN/TPS-1B radar as a result of the Korean War and the threat of a communist attack on Alaska. The guardsmen were designated as Detachment "C-3", 626th Aircraft Control and Warning Squadron, and commanded by the 10th Air Division at Fire Island AFS near Anchorage. The guardsmen were returned to state control in March 1952 and the provisional station was closed.
