USS Sterlet (SS-392) was a Balao-class submarine of the United States Navy, named after the sterlet, a small sturgeon found in the Caspian and Black Seas. Commissioned in 1944, the submarine served during World War II and the Cold War. Sterlet completed six war patrols in the Pacific Ocean during World War II, earning three battle stars. Post-war, the submarine underwent a GUPPY II conversion in the early 1950s to improve its performance and capabilities. During the Cold War, Sterlet operated in the Atlantic and Mediterranean as part of the Sixth Fleet, conducting training exercises and surveillance missions. In 1960, the submarine was decommissioned and transferred to the Italian Navy, where it served as the Ettore Fieramosca (S 506) until being struck in 1974. The USS Sterlet was the only ship of the United States Navy to bear that name. The submarine's service history reflects its role in both World War II and the subsequent Cold War period, demonstrating the adaptability and longevity of naval vessels in the ever-evolving landscape of maritime warfare.
