A pair of low Earth orbiting demonstration satellites built by Northrop Grumman Aerospace Systems for the first time on March 16 detected and tracked a ballistic missile launch through all phases of flight, a Northrop Grumman official said March 22.
So-called birth-to-death tracking of a ballistic missile launch had never been done before from space and is the most significant achievement to date for the Space Tracking and Surveillance System (STSS) spacecraft, said Doug Young, Northrop Grumman’s vice president of missile defense and warning programs.
“It’s the Holy Grail for missile defense,” Young said during a media briefing here.
Los Angeles-based Northrop Grumman built three STSS demonstration satellites for the U.S. Missile Defense Agency (MDA). The first satellite, which had a classified mission, was launched in May 2009. After completing its test program, it was transferred Jan. 31 to the control of Air Force Space Command to continue supporting the service’s space situational awareness mission.
