Cape Cod Space Force Station

Cape Cod Space Force Station is a United States Space Force station located in the northwest corner of Joint Base Cape Cod, United States, on Flatrock Hill in Bourne, Massachusetts. Cape Cod Space Force Station began construction in 1976 as Cape Cod Missile Early Warning Station and was renamed Cape Cod Air Force Station in 1982, before assuming its current name in 2021.

History
On 27 August 1973, the United States Air Force directed the construction of two phased array missile warning radar systems, specifically to defend against the launch of submarine-launched ballistic missiles. On 23 May 1975 it was announced that the east coast site would be located at Otis Air Force Base at Cape Cod and the west coast site would be located at Beale Air Force Base. Construction on the Cape Cod Missile Warning Station began on 26 October 1976. On 1 October 1979, the 6th Missile Warning Squadron and 2165th Communications Squadron were established and the facility became operational on 4 April 1980 under Aerospace Defense Command's 21st Air Division. On 1 December 1979, Aerospace Defense Command's missile warning and space surveillance radars were transferred to Strategic Air Command, with Cape Cod Missile Warning Station becoming part of the 45th Air Division.

On 5 January 1982, Cape Cod Missile Warning Station's name was changed to Cape Cod Air Force Station and became part of Air Force Space Command's 1st Space Wing on 1 May 1983. In 1986, the 2165th Communications Squadron was merged into the 6th Missile Warning Squadron. On 15 May 1992, the 6th Missile Warning Squadron was redesignated as the 6th Space Warning Squadron and reassigned to the 21st Space Wing's 21st Operations Group. On 20 December 2019, the 6th Space Warning Squadron became part of the United States Space Force and on 24 July 2020, the 6th Space Warning Squadron became part of Space Delta 4 and Buckley Garrison became responsible for installation support.

On 11 June 2021, Cape Cod Air Force Station was renamed Cape Cod Space Force Station.

6th Space Warning Squadron
The 6th Space Warning Squadron is responsible for operating the AN/FPS-132 Upgraded Early Warning Radar and is part of Space Delta 4. The 6th Space Warning Squadron has been the host unit at Cape Cod Space Force Station since 1979. In addition to Space Force guardians, there are a number of Royal Canadian Air Force airmen and airwomen assigned to the squadron. The primary mission of the squadron is to guard the United States and Canadian east coast against sea-launched and intercontinental ballistic missile attacks, which is then routed to the Missile Defense Agency and United States Space Command's Missile Warning Center for missile defense operations. The squadron's secondary mission is tracking low-earth-orbiting objects, such as the International Space Station, which is reported to the 18th Space Control Squadron.
