USS Sterlet (SS-392), a Balao-class submarine, was the only ship of the United States Navy to be named for the sterlet, a small sturgeon found in the Caspian Sea and its rivers, whose meat is considered delicious and whose eggs are one of the world's great delicacies, caviar. Her keel was laid down on 14 July 1943 at the Portsmouth Navy Yard. She was launched on 27 October 1943 in the first triple launching in the history of submarine construction. Sterlet and Pomfret were christened in the building basin and Piranha was christened and launched from the building ways.
