NORTHROP: BUILT MISSILE TRACKING SATELLITES REACH 10 YEAR ON ORBIT

The Space Tracking and Surveillance System – STSS satellites built by Northrop Grumman for the US Missile Defense Agency – MDA have far surpassed their four-year on-orbit design life, completing a tenth year of space operations. Still in operation today, the STSS satellites continue to provide critical support for missile and national defense.

“STSS proved that space-based assets could significantly improve our nation’s missile defense capability and paved the way for future systems. Being able to track missiles from low Earth orbit allows threats to be engaged earlier in the process using existing interceptors – said at Spazio-News Magazine Bob Mehltretter, vice president, military and civil space, Northrop Grumman. Northrop Grumman is leveraging all the experience we gained from our legacy OPIR – Overhead Persistent Infrared systems, STSS, DSP – Defense Support Program, and SBIRS – Space Based Infrared System, to develop our nation’s future OPIR programs”.

Two STSS satellites were launched into low Earth orbit in 2009 and proved the operational value of space-based precision mid-course ballistic missile tracking. The Space Tracking & Surveillance System has tracked ballistic missiles through all phases of flight and in 2013 demonstrated the launch on remote capability, which significantly expands the defended area of a Navy Aegis cruiser.
