The 213th Space Warning Squadron of the Alaska Air National Guard provides early warning of Intercontinental ballistic missiles and Submarine-launched ballistic missiles to the Missile Correlation Center of North American Aerospace Defense Command. The squadron is a geographically separated unit assigned to the 168th Wing at Eielson Air Force Base.

The primary mission of the 213th Space Warning Squadron is to provide early warning of intercontinental ballistic missile and submarine-launched ballistic missile launches to the Missile Warning Center at North American Aerospace Defense Command (NORAD). The secondary mission of the squadron is to provide space surveillance data on orbiting objects to the NORAD Space Control Center.

The Ballistic Missile Early Warning System (BMEWS) site at Clear Air Force Station began operation in November 1961, when Detachment 1, 71st Surveillance Wing took over the site from Air Force Systems Command. The detachment was manned by civilian contractors until 1964, when active duty United States Air Force personnel began to operate the site's tactical operations room. At the start of 1967, the detachment was replaced by the newly activated 13th Missile Warning Squadron.

In August 1967, a severe flood inundated the region surrounding Fairbanks, Alaska, and the squadron provided shelter to 216 refugees. The squadron was assigned its first female officer in 1973. By 1986, the squadron would be employing all-female crews. Because of a fire that destroyed part of a similar facility at Thule Air Base, Greenland, in 1981 the missile tracking radar and its radome were disassembled and replaced.
