Apra Harbor, Guam, May 21, 2002 ? The fast attack submarine USS Tucson (SSN 770) transits past the mouth of Apra Harbor, Guam. Tucson, commissioned Sept. 9, 1995, has retractable bow planes to give the ship increased maneuverability. Tucson's stealth design, endurance, and mobility provide the National Command Authority a powerful tool for protecting U.S. interests and supporting allies around the world. The modern submarine is the original stealth weapon. U.S. Navy photo by Photographer's Mate 2nd Class Alan D. Monyelle. [020521-N-9885M-002] May 21, 2002
