The Terminal Automation Modernization and Replacement (TAMR) Program Office deploys and sustains the Standard Terminal Automation Replacement System (STARS). STARS is used by Air Traffic Controllers to ensure the safe separation of both military and civilian aircraft within the nation's terminal airspace. It is a real-time digital processing and display system that replaced legacy air traffic control automation equipment at over 200 FAA and Department of Defense (DoD) Terminal Radar Approach Control (TRACON) facilities, over 600 FAA and DoD Air Traffic Control Tower facilities, and more than 100 systems installed and maintained at STARS support sites including Operational Support Facilities (OSFs) and the FAA Academy airspace.
