The 4 Space Control Squadron (4 SPCS) is a unit within the United States Air Force (USAF) under the Air Force Space Command (AFSPC). Its primary role is space surveillance, providing accurate and timely tracking data for all objects in Earth’s orbit, including satellites and debris. This information is crucial for ensuring the safety of both military and civilian space activities. The 4 SPCS is stationed at Vandenberg Air Force Base, California. The squadron operates the Space Fence system, a ground-based radar network that detects and tracks objects in low Earth orbit. The 4 SPCS plays a significant role in maintaining space situational awareness, which is essential for both national security and peaceful space exploration.
