Space Fence Proposed Locations and References
[edit]Here are two primary references listing the proposed locations of two to three replacement Space Fence Radar Stations.
- United States Government Accountability Office [GAO] (2011), "GAO Report to the Subcommittee on Strategic Forces, Committee on Armed Services, House of Representatives", SPACE ACQUISITIONS Development and Oversight Challenges in Delivering Improved Space Situational Awareness Capabilities (PDF)
On Page 14, the GAO Report lists proposed locations. "The system was to consist originally of up to three geographically dispersed radars (notionally located in Australia; Ascension Island, south Atlantic Ocean; or Kwajalein Atoll, Marshall Islands); however, recent analysis shows that a three-site system may not provide adequate cost-benefit over a two-site system and, therefore, the Air Force considers the likelihood of a two-site solution is very high."
- Defense Acquisition Management, Information Retrieval (DAMIR) (2021), "UNCLASSIFIED, RCS: DD-A&T(Q&A)823-438", Space Fence Ground-Based Radar System Increment 1 (Space Fence Inc 1) As of FY 2021 President's Budget" (PDF)
On Page 7, The President's Budget USAF Document reports on the projects only two locations. "The system, comprising one operations center and two radar sites operating at S-band frequencies... The Space Fence Increment 1 (Inc 1) includes the operations center, located at the Reagan Test Site Operations Center Huntsville, Alabama, and one radar site, located at Kwajalein Atoll, Republic of the Marshall Islands. "
This raises the question what happened to two the additional radar sites?
How much tracking capability has been lost or has it been replace by other stations?
