Civil service mariner David Prater, a rescue swimmer from USS Mount Whitney (LCC 20), jumps from the ship during a swim call in the Tyrrhenian Sea. Mount Whitney, homeported in Gaeta, Italy, is the U.S. 6th Fleet flagship and operates with a combined crew of U.S. Sailors and MSC civil service mariners. The civil service mariners perform navigation, deck, engineering, laundry and galley service operations while military personnel aboard support communications, weapons systems and security.
