USS Bergall (SS-320), a Balao-class submarine in commission from 1944 to 1958, was the first ship of the United States Navy to be named for the bergall, a small fish of the New England coast. During World War II she made five war patrols between 8 September 1944 and 17 June 1945, operating in the South China Sea, Java Sea, and Lombok Strait and north of the Malay Barrier. During these patrols she sank two Japanese merchant ships totaling 14,710 gross register tons and one 740-displacement ton Imperial Japanese Navy frigate. She also damaged the Japanese heavy cruiser Myoko, which was never repaired.
