A US warship successfully shot down a target missile warhead over the Pacific in a test of a sea-based missile defense system, the US military said. A Japanese destroyer performed surveillance and tracking exercises during the test, marking the first time any US ally has taken part in a US missile defense intercept test, the US Missile Defense Agency said.
The sea-based system tested off Hawaii is designed to counter only short or medium range missiles, but the cruisers and destroyers that took part are capable of tracking long-range missiles as well.
The mock warhead was launched over the Pacific atop a medium range missile and destroyed in a direct hit six minutes later with an SM-3 missile fired by the Aegis cruiser USS Shiloh, the agency said. "The missile successfully intercepted the target warhead outside the earths atmosphere more than 100 miles above the Pacific Ocean and 250 miles northwest of Kauai," the agency said in a statement.
"We are continuing to see great success with the very challenging technology of hit-to-kill, a technology that is used for all of our missile defense ground- and sea-based interceptor missiles," Lieutenant General Trey Obering, the agency chief, said in the statement.
He said it was the seventh successful intercept using the sea-based missile defense system out of eight tries.
So the SM-3 part of the ballistic missile defense is very likely to work under good to ideal conditions. They'll need to figure out all the limitations, but this is really good news. | Missile Defense Agency officials have said the missile interceptor test was long-planned and had nothing to do with North Korea's long-range missile launch plans. But the agency's statement highlighted the role of the Japanese Aegis destroyer. "This event marked the first time that an allied military unit participated in a US Aegis missile defense intercept test," it said.
It said the Japanese destroyer and a US Navy Aegis destroyer performed surveillance and tracking exercises during the test. "This data can also be used to provide targeting information for other missile defense systems, including the ground-based long-range interceptor missiles now deployed in Alaska and California to protect all 50 states from a limited ballistic missile attack," the agency said.
So the Japanese have a good knowledge base and know how to do what we know how to do. All they need is the interceptor. | A third Aegis destroyer used in the test linked up with a land-based missile defense radar to evaluate the ship's ability to receive and use target cueing data from missile defense command centers.
The mock warhead separated from the three-stage target missile. The direct hit marked only the second time a separating warhead has been successfully intercepted by a missile fired from an Aegis cruiser. The cruisers use their modified Spy-1 radars and a shipboard battle management system to detect, track and target the warheads in space. The SM-3 Block IA interceptor missile fired in Thursday's test is slated for deployment in the US Navy and had never been used before in an intercept test. |
