US military aborts missile defense test after launch falters

The US military has aborted a short-range ballistic missile defense test off the Hawaiian island of Kauai after a target missile malfunctioned shortly after launch. The failure halted the US Missile Defense Agency's first attempt to fire two interceptors at one target using the terminal ground-based missile defense system. It was the first breakdown after five successful tests of the Terminal High Altitude Area Defense system, or THAAD. The defense agency says that because of the failure, the two THAAD interceptor missiles that were to take part in the test were not launched. So the full test was never completed. The military group says it will review data from the failed test in an extensive investigation of the cause of the malfunction in the target launch.
