HONOLULU -- The U.S. military on the Hawaiian island of Kauai has conducted the first flight test of a new missile defence system designed to protect NATO forces in Europe from ballistic missile attack, the Pentagon said Wednesday.

The Missile Defence Agency and the Navy used the Aegis Weapon System to track a simulated target in Tuesday evening's test. They successfully intercepted the simulated target using a Standard Missile-3 Block IB missile made by Raytheon Co.

Another test next year will have a missile intercept an actual target.

The European Phased Adaptive Approach plan for missile defence calls for the first Aegis Ashore to be operational in Romania next year, Raytheon said. The second Aegis Ashore site is on track for Poland in 2018.

The Aegis Ashore system uses the same SM-3 missile deployed on U.S. and Japanese navy ships today. The system holds 24 SM-3 missiles at one time but has the capacity for additional launchers and missiles.

The missiles destroy incoming ballistic missile threats in space using sheer impact. Raytheon said the force is equivalent to a 10-ton truck travelling 600 mph (965 kph).

Tuesday's test was the first of the Aegis Ballistic Missile Defence system using a land-based missile launcher. Interceptor missiles were launched from ships in previous tests.
