Thule Air Base, established in northern Greenland in 1951, served as a critical forward staging point for Strategic Air Command bombers during the early Cold War. Its extreme northern location placed Soviet targets within closer striking range, and aircraft rotated through under the 'Reflex' alert program to maintain a constant nuclear deterrent posture. This aerial view captures the base's ramp crowded with jet bombers, a vivid record of America's Arctic front line in the 1950s. Project: 218295
