This category is for U.S. automatic tracking radar stations — ground radar installations for automatically maintaining alignment (autotrack) of the radar antenna toward an air target for continuously measuring its location, e.g., manned aircraft, winged missile, ballistic missile, surface-to-air missile, or meteorological balloon.
Most autotrack stations were closed at the end of the Cold War with development of Precision-guided munitions (PGMs) with GPS accuracy, No-Drop Bomb Scoring systems, and portable phased array radars that measure target location without moving the antenna.
