A U.S. Navy exercise last week practiced defending Israel against a combined missile attack from Syria, Lebanon and Iran. The exercise involved two Aegis warships, one off the coast of Israel, and the other in the Persian Gulf, StrategyPage reported. The website noted that the exercise was meant to "send a message."

"So far, the Aegis system has knocked down nearly 90 percent of the missiles fired towards it. This includes shooting down a low flying space satellite," the report said. The Aegis system consists of anti-aircraft missiles combined with the Aegis radar system, that shoots down ballistic missiles.

The recent exercise mainly tested the communications and computer operations of the Aegis systems in the two warships. No missiles were actually fired.
