This image taken from Iranian state TV, shows damage to a mock U.S. aircraft carrier during large-scale naval and air defense drills by Iran's Revolutionary Guard, near the Strait of Hormuz, Iran, Wednesday, Feb. 25, 2015. The drill, named Great Prophet 9, was the first to involve a replica of a U.S. carrier. Cmdr. Kevin Stephens, the spokesman for the U.S. Navy's 5th Fleet in Bahrain, said they were monitoring the drills, but downplayed the simulated attack on the carrier, saying the U.S. military was "not concerned about this exercise."(AP Photo/Iran TV) TV OUT
