The Missile Defense Agency’s two space tracking and surveillance system demonstration satellites detected and tracked a Minuteman III ICBM that was launched from Vandenberg AFB, Calif., during a recent test mission over the Pacific Ocean, according to Northrop Grumman. The company is the prime contractor for these satellites, having built them with an industry team including Raytheon. According to Northrop’s July 16 release, the two STSS satellites transmitted tracking data on the Minuteman during the June 16 flight to the missile defense integration and operations center at Schriever AFB, Colo., where the information is being analyzed. Gabe Watson, Northrop’s vice president of missile called the satellites’ involvement “another reliable performance” that is “an encouraging development for the nation’s missile defense system.” Earlier in June, the STSS spacecraft detected and tracked a missile defense interceptor fired from Vandenberg.
The U.S. military is doubling down on non-space-based alternatives to GPS, the ubiquitous position, navigation, and timing service provided by the U.S. Space Force, with new funding for the development and testing of operational prototypes of quantum-based devices that don’t depend on easily jammable signals from satellites.
