US Missile Defense Agency Tests UAS For Boost-Phase Targeting
The U.S. Missile Defense Agency (MDA) plans to continue testing the use of Reaper unmanned aircraft for ballistic missile target discrimination in the near term because taking that mission to space is still too costly.
The agency terminated plans this year to design and build a follow-on to the two orbiting Space Tracking Surveillance System satellites, which have been used to launch a ship-based SM-3 successfully against a target. “We want to go to space,” said Rich Matlock, director of advanced technology for MDA. But fielding a constellation of satellites capable of acquiring a target and tracking it through the midcourse of flight is far too expensive a goal for the near term.
Instead, MDA is experimenting with using unmanned aircraft to look up at targets, providing additional discrimination and targeting information. MDA has purchased at least four Raytheon MTS-B payloads for this purpose. But the goal is to test the upgraded MTS-C, which will incorporate a long-wave infrared detector into the system. Long-wave infrared is optimized for tracking cold bodies, such as missiles and warheads after booster burnout, or plumes and exhaust.
Ground testing will be conducted on the improved system in the next two months… [article was published in 2013]
