The Space Fence ground infrastructure is located in the Marshall Islands, and currently is in the “initial operational capability and operational acceptance” phase. The program will track the existing 26,000 orbital objects already accounted for in the existing Space Surveillance Network (SSN), but Space Force said via an update on the new operational phase that it expects to grow that list quickly with its own additions.
