The USS Helena refers to several ships in the United States Navy, named after the city of Helena, Montana. The most notable was the USS Helena (CL-50), a light cruiser commissioned in 1943. It served during World War II, participating in key battles in the Pacific Theater, including the Battle of Guadalcanal. Another significant vessel was the USS Helena (SSN-725), a nuclear-powered attack submarine commissioned in 1984. This submarine is part of the Los Angeles-class and is designed for anti-submarine warfare, intelligence gathering, and special operations support. Both ships reflect the U.S. Navy's commitment to maritime defense.
