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.[2]
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.[2]
The radar at Clear was the last mechanically operated BMEWS site. In 1998 the radar began to be converted to a phased array radar by employing components of the PAVE PAWS submarine-launched ballistic missile detection site from the closed facility at Eldorado Air Force Station near Goodfellow Air Force Base, Texas. The new system, known as the Solid-State Phased-Array Radar System, achieved initial operating capability on 31 January 2001.[2]
On 21 May 2004, the 213th activated at Clear Air Force Station. In 2006, the 213th Space Warning Squadron became the majority force provider to the mission of Clear Air Force Station by providing both space operations crews for the early warning radar and security forces for the installation. The early warning radar supports ballistic missile warning for threats to North America. Clear Air Force Station consists largely of Air National Guard members assigned to the 213th, but the smaller active duty squadron, 13th Space Warning Squadron, maintains responsibility for both the installation and execution of the mission.
