New York Times – U.S. Speeding Up Missile Defenses in Persian Gulf

General Petraeus said that the acceleration of defensive anti-missile systems in the Persian Guolf — which began when President George W. Bush was in office — included “eight Patriot missile batteries, two in each of four countries.” Patriot missiles are capable of shooting down short-range offensive missiles. He also described a first line of defense: He said the United States was now keeping Aegis cruisers on patrol in the Persian Gulf at all times.
