Test of new U.S. interceptor missile results in failure

A modernized version of the SM-3 missile has failed to intercept a ballistic missile target during a test over the Pacific Ocean, the U.S. Missile Defense Agency (MDA) said. A Standard Missile 3 (SM-3) Block 1B interceptor missile was launched on Monday from the cruiser USS Lake Erie (CG-70) to intercept a short-range ballistic missile target launched from the U.S. Navy's Pacific Missile Range Facility on the island of Kauai. "This was the first flight test of the advanced SM-3 Block 1B interceptor missile," the agency said in a statement. "Program officials will conduct an extensive investigation to determine the cause of the failure to intercept."According to the statement, the MDA has conducted 22 successful intercepts in 27 at-sea test launches of interceptor missiles under Aegis Ballistic Missile Defense System flight testing program since 2002. The SM-3 missile is expected to become a key part of the Obama administration's European Phased Adaptive Approach (PAA) for defending the continent against ballistic missile attacks. The missile is equipped with a kinetic warhead which does not carry any high explosive. Hit-to-Kill technology relies on the kinetic energy released in a high-speed collision between the warhead and the target. The energy from the impact is equivalent to the force released when a 10-ton truck traveling at 600 mph hits a wall.
