Distant Interstellar Warning Line

Established during the Evacuation Effort of Earth, the Distant Interstellar Warning Line was created to act as a international trip-wire for Scinfaxi activity. At its height, the United Kingdom, Greater German Reich, and Union of Soviet Socialist Republics deployed nearly ten-thousand automated sensor buoys and dozens of manned station. After a century of use with no reported sightings, the Greater German Reich and Soviet Union both separately deemed the continuation of the project unnecessary. Following the Soviet and German withdrawals from the program in the 2260s, the United Kingdom has confirmed the scheduled decommissioning of its own assets by 2289.
