AN/FPS-85

The AN/FPS-85 is a high-powered radar system used by the United States to detect and track objects at great distances, primarily for missile warning during the Cold War. It is part of the Ballistic Missile Early Warning System (BMEWS) and operates by sending out radio waves that bounce off incoming objects like missiles or aircraft. When these waves return, the system analyzes the signals to determine the location, speed, and trajectory of the objects. Its large size and advanced technology enable it to monitor threats across vast areas, providing early warning to help defend against potential missile attacks.
