On February 21, 2011, Israel conducted a successful test of the Arrow 2 ballistic missile defense system, destroying a target simulating an Iranian ballistic missile off the coast of California. Conducted jointly by the Israeli Air Force, the Israeli Defense Ministry's Homa Missile Defense Agency and the U.S. Missile Defense Agency, it was the eighteenth test of the Arrow and the second in which the modified Arrow 2 was tested in its entirety. The exercise also tested the Green Pine radar, manufactured by Israel Aerospace Industries, which detected and identified the enemy missile and related the information to the Arrow battery which launched the missile interceptor around 10:30 pm Pacific Standard Time from a U.S. Naval base along the California coast.
Arieh Herzog, head of the Homa Missile Defense Agency, said that the Arrow system worked as designed and completely destroyed the target. Defense officials also said the Arrow system could protect Israel from all of the missiles in Iran's arsenal.
