The USS Tunny (SS/SSG/APSS/LPSS-282) was a Gato-class submarine which saw service in World War II and in the Vietnam War. Tunny received nine battle stars and two Presidential Unit Citations for her World War II service and five battle stars for her operations during the Vietnam War.

Tunny was the first submarine of the United States Navy to be named for the tunny, any of several oceanic fishes resembling the mackerel, and her keel was laid down on 10 November 1941 at Vallejo, California, by the Mare Island Navy Yard. She was launched on 30 June 1942 sponsored by Mrs. Frederick G. Crisp, and commissioned on 1 September 1942 with Lieutenant Commander Elton Watters Grenfell in command.

Following shakedown training out of California ports, Tunny arrived in the Hawaiian Islands on 12 December 1942. After an additional week of training and two weeks of availability, she got underway from Submarine Base, Pearl Harbor, on 12 January 1943 for her first war patrol. For nearly a week, rough seas hampered the progress of the submarine. Then, as she approached the Ryukyu Islands, sea traffic increased. Sightings of sampans became frequent, and Tunny often dove to avoid detection by suspicious-looking trawlers.

At 05:30 on 26 January, Tunny sighted masts and a stack over the horizon indicating a possible target. During the day, she lessened the distance between herself and her quarry; and, near dusk, she closed a 400-ton trawler. Finding the prey not worth a torpedo, the submarine surfaced and opened fire with her deck gun. Soon, darkness forced her to discontinue the attack, and she continued on her way.
