Tin City AFS was a continental defence radar station constructed to provide the United States Air Force early warning of an attack by the Soviet Union on Alaska.

It was one of the ten original radar surveillance sites constructed during the early 1950s to establish a permanent air defense system in Alaska.

The Army Transportation Corps undertook the project, code name Mona Lisa, of getting the initial supplies and equipment to the construction site.

65°33′44″N 167°55′24″W / 65.56222°N 167.92333°W / 65.56222; -167.92333 (Tin City LRRS Airport) The station consisted of a power/heating plant, water and fuel storage tanks, gymnasium and other support office buildings.

Two other buildings contained living quarters, work areas, and recreational facilities plus opportunities for such sports as skiing, skating, horseshoes, and basketball.

It was inactivated in 1979, and replaced by an Alascom owned and operated satellite earth terminal as part of an Air Force plan to divest itself of the obsolete White Alice Communications System and transfer the responsibility to a commercial firm.

In 1983, Tin City AFS received a new AN/FPS-117 minimally attended radar under Alaskan Air Command's SEEK IGLOO program .

It was designed to transmit aircraft tracking data via satellite to the Alaskan NORAD Regional Operations Control Center (ROCC) at Elmendorf AFB.

No longer needed, the 710th AC&W Sq was inactivated on 1 November 1983 and the station re-designated as a Long Range Radar (LRR) Site.

In 1998 Pacific Air Forces (PACAF) initiated "Operation Clean Sweep", in which abandoned Cold War stations in Alaska were remediated and the land restored to its previous state.
