JTAGS receives and processes information directly down-linked from the Defense Support Program and other infrared satellite sensors.
Using multiple communications networks, the system then distributes near-real-time warning, alerting and cueing data on ballistic missile launches and other tactical events of interest throughout the theatre.

Since 1994, Northrop Grumman has served as the JTAGS prime contractor under the direction of the Army Space and Missile Defense Command, Redstone Arsenal, Alabama.

The company has been responsible for developing, fielding, maintaining and improving the JTAGS system across the globe.
