ST. LOUIS, 21 July 2008 Boeing, industry teammates, and the U.S. Missile Defense Agency, successfully completed a Ground-based Midcourse Defense (GMD) system test that demonstrated the most complex integration to date of sensors required to support a missile intercept.
While previous tests typically involved a single target-tracking sensor, this test used four the Aegis Long Range Surveillance and Track system in the Pacific; the AN/TPY-2 radar in Juneau, Alaska; the Upgraded Early Warning Radar at Beale Air Force Base, Calif., and the Sea-Based X-Band Radar (SBX) in the Pacific.
During the test, the sensors detected, tracked, and assessed a long-range ballistic missile target launched from the Kodiak Launch Complex in Alaska. The sensors provided target information via ground and satellite links to GMD's dual-node, distributed fire control system, located at Fort Greely, Alaska, and in Colorado Springs, Colo. The fire control system combined the sensor data, generated accurate targeting coordinates, and simulated a target shootdown with a virtual ground-based interceptor.
"This successful test verified that four sensors separated by thousands of miles can detect, track, and provide precise trajectory information to help defend against a long-range ballistic missile attack," says Scott Fancher, vice president and general manager of Boeing Missile Defense Systems. "The test builds on the momentum of the GMD program, which achieved intercepts with operationally configured interceptors in each of the past two years."
"This test demonstrated GMD's network-centric ability to use data gathered from multiple, global sensors to give us a clearer picture of an incoming threat and greatly increase our ability to intercept that threat," says Greg Hyslop, vice president and program director for GMD. "The sensor integration required for this test greatly reduces risk for our next intercept test, which will be the most challenging ever."
Boeing is the prime contractor for GMD, which provides the nation's only defense against long-range ballistic missiles. GMD consists of sensors, command-and-control facilities, communications terminals, a 20,000-mile fiber optic communications network, and interceptors deployed in underground silos at Fort Greely and at Vandenberg Air Force Base, Calif. Industry partners include Raytheon, Orbital Sciences Corp., and Northrop Grumman.
