The Royal Navy Trafalgar class attack submarine HMS Tireless sits on the surface of the North Pole. Tireless surfaced with the U.S. Navy Los Angeles-class attack submarine USS Hampton (SSN 767) for ICEX 04, a joint operational exercise beneath the polar ice cap. Both the Tireless and Hampton crews met on the ice, including scientists traveling aboard both submarines to collect data and perform experiments. The Ice Exercise demonstrates the U.S. and British Submarine Force's ability to freely navigate in all international waters, including the Arctic. U.S. Navy photo by Chief Journalist Kevin Elliott
