The Los Angeles-class fast attack submarine USS Scranton (SSN 756) breaks through the Artic ice. For the first time in 33 years, Scranton was one of two U.S. submarines to surface at the North Pole. Scranton and her crew broke through almost four feet of ice as a part of Atlantic Submarine Ice Exercise (LANTSUBICEX) 1-01, a three-ship exercise which demonstrated the U.S. Navys commitment to assure access to all international waters. www.navy.mil
