; The Problem: Current Sensor Systems Do Not Provide Continuous Global Coverage "The U.S. doesn'tpossess a System for continuously tracking ballistic warheads in midcourse, and that makes effective interception mue h less likely no matter what dfense weapons and sensors await the warheads when they enter thelr terminal or re-entry phase of their trajectory." Loten Thompson, chief operaUng omtc, Lexington Insiitute Commentafy tn Dfense News, Sept. 10,2007 Current sensor Systems are limited in their ability to provide continuous global coverage.

Space-Based Midcourse Tracking Extends the Range of Interceptors BOOST PHASE MIDCOURSE PHASE RE-ENTRY PHASE l The STSS Demonstrator Program As a space-based sensor System, STSS provides both global coverage and earlier tracking of missiles in flight, maximizing the defended area of the interceptor Systems. STSS track data provided to the Aegis weapons System would allow it to focus energy in the direction of the incoming missile and pick up the threat earlier, providing earlier interceptor launch and expanded area dfense. Ground Based Interceptor bases in Alaska and California would also...

A National Imperative “Our real problem, then, is not our strength today; it is rather the vital necessity of action today to ensure our strength tomorrow.” Former U.S. President Dwight D. Eisenhower State of the Union Address _ 1958 The threat is global and unpredictable. The global sensor capability of STSS provides the unique tracking solution through all phases of a ballistic missile trajectory. Fielding all three segments of the missile defense architecture (the eyes, the brains, and the muscles) will increase our missile defense capabiltiy as the threat continues to grow. It is a...
