Japan-U.S. missile defense test fails off Hawaii

A Japanese warship failed to shoot down a ballistic missile target in a joint test with U.S. forces Wednesday because of a glitch in the final stage of an interceptor made by Raytheon Co, a U.S. military official said.

The kinetic warhead’s infrared “seeker” lost track in the last few seconds of the $55 million test, about 100 miles above Hawaiian waters, said U.S. Rear Admiral Brad Hicks, program director of the Aegis sea-based leg of an emerging U.S. anti-missile shield.

“This was a failure,” he said in a teleconference with reporters. It brought the tally of Aegis intercepts to 16 in 20 tries.

The problem “hopefully was related just to a single interceptor,” not to a systemic issue with the Standard Missile-3 Block 1A, the same missile used in February to blow apart a crippled U.S. spy satellite, Hicks said.

Military officials from both countries said in a joint statement there was no immediate explanation for the botched intercept of a medium-range missile mimicking a potential North Korean threat. The test was paid for by Japan, Hicks said.

John Patterson, a spokesman at Raytheon Missile Systems in Tucson, Arizona, said the company would not comment pending the results of an engineering analysis of what may have gone wrong.
