| Breakthrough In Ballistic Missile Tracking |
| 2011-03-24 |
| 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. Today, Navy Aegis ships are only able to launch interceptors to defeat ballistic missiles after they are detected by the ship’s own radar. If the interceptors can be fired based on cuing from forward-based sensors, the area that each ship can defend from missiles is greatly increased. The Navy and MDA plan to conduct the first Aegis launch-on-remote intercept test next month, for which a forward-based AN/TPY-2 X-band radar will cue the launch of a Standard Missile (SM)-3 interceptor before the target missile is detected by the ship’s radar. Similarly, the STSS demonstration satellites later this year will attempt to track a target missile and feed data to the Aegis system to generate a “fire control solution” for an early interceptor launch, Young said. However, an interceptor will not actually be launched in that test, he noted. Meanwhile, the MDA is pursuing an operational constellation of geosynchronous missile tracking satellites dubbed the Precision Tracking Space System. The agency will rely on the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., to develop a prototype system to be launched in 2015. An industry team is expected to be chosen in 2014 to build between nine and 12 operational spacecraft planned to begin launching in 2018. |
