73d Space Group

The 73d Space Group is an inactive United States Air Force space surveillance organization. Its last assignment was with Fourteenth Air Force, being stationed at Falcon Air Force Base, Colorado. It was inactivated on 26 April 1995.

The Group performed space surveillance. In April 1995 the 73d Space Surveillance Group merged with the 21st Space Wing. From that point the 21st became the largest wing in the United States Air Force with units deployed throughout the world.

History

The group was first organized at Ent Air Force Base, Colorado on 1 January 1967 as the 73d Aerospace Surveillance Wing, joining the 71st Surveillance Wing as one of the two wings in Air Defense Command's 9th Aerospace Defense Division, which was responsible for the Air Force's contribution to the defense of North America to space oriented attack. The 71st Wing, which was soon renamed the 71st Missile Warning Wing, was responsible for the Ballistic Missile Early Warning System, while the 73rd focused on space based systems. The wing's operational elements were the 16th Surveillance Squadron at Shemya Air Force Station, Alaska, the 17th Surveillance Squadron at Moorestown Air Force Station, New Jersey, the 18th Surveillance Squadron at Edwards Air Force Base, California. the 19th Surveillance Squadron at Pirinclik Air Station, Turkey and the 20th Surveillance Squadron at Eglin Air Force Base, all organized the same day as the wing.Like the wing, the component squadrons were to be activated as "aerospace" surveillance squadrons. However, on 3 January 1967, the decision was made to retroactively drop the "aerospace" from the squadron names. Cornett & Johnson, pp. 149-150. Sensor operations included the Spacetrack System. The wing was inactivated in April 1971.

The 73rd was reactivated on 1 March 1989 as the 73d Space Surveillance Group. On 1 October 1992, Detachment 3 at Misawa Air Base, Japan (which had been added on 1 January 1991) was expanded to form the 3rd Space Surveillance Squadron. It was inactivated in April 1995.
