Aviation Boatswain's Mate 2nd Class Tyler Stives, from Spring, Texas, inspects a catapult after an aircraft launch aboard the aircraft carrier USS George Washington during Annual Exercise 2013. The USS George Washington took part in a joint military naval drill with Japan on Thursday in waters off southern Japan, just days after it participated in humanitarian relief operations in the Philippines. More than 20 ships and 7000 U.S. personnel participated in this year's Annual Exercise 2013 which aims at strengthening ties between the United States Navy and the Japan Maritime Self Defence force. While the U.S. Navy would not confirm the exact coordinates, they were able to say the event took place, at one point at least, some 300 kilometers (186 miles) south east of Japan's southern most the islands of Okinawa. This is in the general vicinity, though not within, the new airspace defense zone which China newly established last week.
