Military unit
The 4th Space Warning Squadron is an active United States Air Force Reserve Command unit, formerly located at Holloman Air Force Base, New Mexico, and now located at Buckley Space Force Base. The unit was activated on 3 August 2019. It was previously activated in May 1992 as the 4th Space Communications Squadron, when it took over the mission and personnel of the 4th Satellite Communications Squadron, before being inactivated in March 1996. The squadron's primary mission is to provide mobile Defense Support Program support in case of hostilities.
Mission
The squadron provided worldwide missile warning, space launch and detection in the event of an attack against the United States.
History
The 4th Space Warning Squadron was activated on 15 May 1992, when it took over the mobile Defense Support Program (DSP) satellite mission which had been performed since 1983 at Holloman Air Force Base, New Mexico by the 1025th Satellite Communications Squadron, Mobile[note 2] and the 4th Satellite Communications Squadron, Mobile.[note 3]
The squadron employed the Air Force's only strategic survivable, mobile ground system to receive early warning missile attack data. The 4th provided survivable and endurable missile warning detection to the National Command Authority and had the ability to survive and operate through all phases of trans/post attack. Unlike fixed units, the 4th was designed to be mobile, and could deploy to any location in the world. In addition, the DSP satellites provided immediate, worldwide missile warning, space launch, and nuclear detonation detection.
^The 1025th was designated by Air Force Space Command and activated on 1 October 1983 and was assigned directly to Space Command, then to the 1st Space Wing. It was inactivated on 1 August 1986, when its mission, personnel and equipment were transferred to the 4th Satellite Communications Squadron, Mobile.
^The 4th AACS Squadron, Mobile was activated at Elmendorf Air Force Base on 16 February 1954, assigned to the 1804th AACS Group and inactivated on 18 December 1957. Mueller, p. 163 (dates at Elmendorf). It was disbanded on 15 June 1983, but reconstituted as the 4th Satellite Communications Squadron, Mobile and activated on 1 August 1986, when it took over the assets of the inactivating 1025th Satellite Communications Squadron, Mobile. It was inactivated on 15 May 1992, being replaced by the 4th Space Communications Squadron. Fifteen days later it was activated as the 4th Communications Squadron at Seymour Johnson Air Force Base, North Carolina and is still active there.
