US Jet Intercepts Ballistic Missile

A US F-16 fighter used an air-to-air missile to destroy a sounding rocket in its boost phase for the first time this week in a test of a new missile defense concept, US spokesmen said. The system -- named the Net-Centric Airborne Defense Element (NCDE) -- breaks new ground in that it would arm fighter aircraft or drones with missiles fast enough to intercept a ballistic missile as it lifts into space. The aircraft would have to get to within a 100 miles of the launch site to catch the ascending missile in the first two to three minutes after launch. But it could be very useful in a short range combat situation against short and medium range missiles, said Rick Lehner, a spokesman for the US Missile Defense Agency. The Pentagon has two other better known boost phase intercept systems under development -- the Airborne Laser and the Kinetic Energy Interceptor -- but those are still years away from being ready, he said. "So it does give us an initial boost phase capability even though it is a much shorter range missile, and you have to be in the area of the missile launch to be effective," Lehner said.The test Monday at White Sands Missile Range in New Mexico involved an F-16 fighter that fired two modified AIM-9X missile at an Orion sounding or research rocket. The first destroyed the rocket and the second recorded the interception, the Pentagon's missile defense agency said. The missile seekers' relayed images of the rocket at close range, demonstrating the capability to acquire and track the target, the Pentagon's missile defense agency said. "Although not unexpected, the subsequent intercept destroyed the target," it said. "A second AIM-9X launched during the test observed through its seeker the intercept of the target by the first and was also on a trajectory to intercept the target," the agency said. Besides special seekers, AIM-9X and AIM-20 AAMRAM are fitted with a new liquid propellant second stage to give it the burst of speed needed to catch a ballistic missile in its boost phase. Lehner said the missiles were heavily instrumented during the test, but otherwise conditions were "pretty realistic." Raytheon Missile Systems, which developed the NCADE, said it "provides a revolutionary, low-cost approach to interceptor development and acquisition."
