On December 4, a target missile’s failure to conform to safety requirements caused Israeli program officials to cancel its scheduled test of an Arrow-3 missile interceptor, declaring a ‘no-test.’ The joint Israeli Defense Ministry and U.S. Missile Defense Agency test ended before Arrow 3 systems could even come online, after on-site engineers noticed the target missile was not behaving as expected. Moshe Patel, director of the Israel Missile Defense Organization, emphasized that “the experiment was not a failure.” Data is being collected and analyzed by engineers to determine what caused the target missile to behave unexpectedly, and to continue Arrow-3 development.
