The aircraft carrier USS Kitty Hawk departs Pearl Harbor after a brief port visit after the conclusion of Rim of the Pacific 2008. RIMPAC is the world's largest multinational exercise and is scheduled biennially by the U.S. Pacific Fleet. Participants include the United States, Australia, Canada, Chile, Japan, the Netherlands, Peru, Republic of Korea, Singapore, and the United Kingdom. This was Kitty Hawk's last exercise before returning to the U.S. mainland for decommissioning in early 2009. Kitty Hawk will be replaced by the nuclear-powered aircraft carrier USS George Washington this summer as the only U.S. carrier operating from Japan.
