The USS Trout (SS-566) was a Tang-class submarine commissioned by the United States Navy in 1952. Constructed by the Electric Boat Division of General Dynamics in Groton, Connecticut, her keel was laid on December 1, 1949, and she was launched on August 21, 1951. The vessel was sponsored by Mrs. Albert H. Clark and officially commissioned on June 27, 1952. As a Tang-class submarine, Trout featured advanced design elements typical of post-World War II submarines, though specific dimensions and technical specifications are not detailed in the provided content. Throughout her service, USS Trout operated primarily out of New London, Connecticut, as part of Submarine Squadron 10 until 1959. She engaged in various training, readiness exercises, and antisubmarine warfare drills across the North Atlantic, Caribbean, and Arctic waters. Notably, she set a submerged distance record of 268 nautical miles beneath ice floes near Newfoundland during exercises with her sister ship Harder. In 1959, she transitioned her home port to Charleston, South Carolina, and deployed to the Mediterranean with the Sixth Fleet, participating in international celebrations and NATO exercises. In the early 1960s, Trout served as a test platform for shock tests and continued earning recognition, such as the Battle Efficiency Award in 1961. She participated in multiple Mediterranean deployments during the 1960s, supporting NATO operations and U.S. Navy exercises. In 1970, she was reassigned to the Pacific Fleet, homeported in San Diego, and conducted Western Pacific deployments in the early 1970s, mainly focused on antisubmarine warfare training with allied navies. A unique aspect of her later service was her role in the 1978 film Gray Lady Down, where she was filmed repeatedly diving and surfacing to portray a fictional nuclear submarine. In 1978, she was transferred to the Iranian Navy and renamed IIS Kousseh (SS 101). However, following the Iranian Revolution, she was abandoned in 1979, returned to U.S. custody in 1992, and sold for scrap in 1994. Her subsequent use as a sonar target and research vessel culminated in her scrapping in 2009, marking the end of her nearly five-decade service life.
