Clear Air Force Station
Clear Space Force Station is a United States Space Force radar station for detecting incoming ICBMs and submarine-launched ballistic missiles to NORAD's command center and to provide Space Surveillance data to the United States Space Force. Clear's AN/FPS-123 Upgraded Early Warning Radar is part of the Solid State Phased Array Radar System (SSPARS) which also includes those at Beale AFB, Cape Cod Space Force Station, RAF Fylingdales and Thule Site J. The "historic property" was one of the Alaska World War II Army Airfields and later a Cold War BMEWS site providing NORAD data to Colorado's BMEWS Central Computer and Display Facility (CC&DF). In addition to the "original camp area" with buildings still in use today, areas of the station include the airfield , the "SSPARS Site" the technical site (Utilador, BMEWS reflectors, support buildings, power plant), and the composite site (two permanent dormitories, a mess hall, recreation area, and administrative area).

Eareckson Air Station
Eareckson Air Station , formerly Shemya Air Force Base, is a United States Air Force military airport located on the island of Shemya, in the Alaskan Aleutian Islands. The airport was closed as an active Air Force Station on 1 July 1994. However, it is still owned by the USAF and is operated by the USAF Pacific Air Forces Regional Support Center at Elmendorf AFB for refueling purposes. It also serves as a diversion airport for civilian aircraft. The base previously hosted the AN/FPS-17 and AN/FPS-80 radars and since 1977 the more powerful AN/FPS-108 COBRA DANE phased-array radar. Overview Eareckson Air Station is located on the western tip of Alaska's Aleutian islands near the larger island of Attu, lying approximately 1,500 miles southwest of Anchorage. The airport lies on the south side of the 2-mile by 4-mile island and is 98 feet above mean sea level. Shemya Island has been the scene of two major earthquakes.

RAF Fylingdales
Royal Air Force Fylingdales (RAF Fylingdales) is a Royal Air Force List of Royal Air Force stations, station on Snod Hill in the North York Moors, England. Its motto is ''Vigilamus'' ("We are watching"). It is a radar Military base, base and is also part of the Ballistic Missile Early Warning System (BMEWS). As part of intelligence-sharing arrangements between the United States and United Kingdom (see, for example, the UKUSA Agreement), data collected at RAF Fylingdales are shared between the two countries. Its primary purpose is to give the Government of the United Kingdom, British and Federal government of the United States, US governments warning of an impending ballistic missile attack (part of the so-called four minute warning during the Cold War). A secondary role is the detection and tracking of orbiting objects; Fylingdales is part of the United States Space Surveillance Network. As well as its early-warning and space-tracking roles, Fylingdales has a third function ...

Mears Memorial Bridge
The Mears Memorial Bridge is a truss bridge on the Alaska Railroad, completed in 1923. The bridge spans the Tanana River at Nenana and at , it is among the largest simple truss-type bridges in the world. History The bridge's namesake, Colonel Frederick Mears, was chairman and chief engineer of the Alaska Engineering Commission, the railroad's builder and original operator. The bridge was the final link in the railroad, entering service in February 1923, a year after the rest of the line was finished. The AEC hired the Chicago firm of Ralph Modjeski and Angier to design the bridge, and the American Bridge Company to fabricate and erect it. When completed, this Pennsylvania through-truss bridge was the longest truss span in the United States and its territories. This bridge still ranks as the longest span of any kind in Alaska. it was then the third-longest simple truss bridge in North America. President Warren G. Harding, becoming the first president to visit Alaska, t ...

BMEWS Central Computer And Display Facility
The RCA 474L Ballistic Missile Early Warning System (BMEWS, 474L System, Project 474L) was a United States Air Force Cold War early warning radar, computer, and communications system, for ballistic missile detection. The network of twelve radars, which was constructed beginning in 1958 and became operational in 1961, was built to detect a mass ballistic missile attack launched on northern approaches or15 to 25 minutes' warning time also provided Project Space Track satellite data (e.g., about one-quarter of SPADATS observations). It was replaced by the Solid State Phased Array Radar System in 2001. Background The Ballistic Missile Early Warning System (BMEWS) was a radar system built by the United States (with the cooperation of Canada and Denmark on whose territory some of the radars were sited) during the Cold War to give early warning of a Soviet intercontinental ballistic missile (ICBM) nuclear strike, to allow time for US bombers to get off the ground and land-based US I ...
