Souda Bay, Crete, Greece (Jul. 17, 2004) Master-at-Arms Seaman Apprentice Nathan Hastings, from Henry, Ill., scans the surrounding area while standing a pier security watch as the Los Angeles-class attack submarine USS Dallas (SSN 700) prepares to get underway from Souda Bay, Crete, Greece. Commissioned in 1981, Dallas is the first Los Angeles-class submarine to have a Dry Deck Shelter (DDS). Dry Deck Shelters provide specially configured nuclear powered submarines with a greater capability of deploying Special Operations Forces (SOF). DDSs can transport, deploy, and recover SOF teams from Combat Rubber Raiding Crafts (CRRCs) or SEAL Delivery Vehicles (SDVs), all while remaining submerged. In an era of littoral warfare, this capability substantially enhances the combat flexibility of both the submarine and SOF personnel. U.S. Navy photo by Paul Farley File# 040719-N-0780F-012
