English: Starboard view of the U.S. Navy submarine USS Queenfish (SS-393), underway circa in the 1950s, location unknown. Her deck guns had been removed by this time. When her guns and associated equipment were removed, she became the model for active fleet-type boats that did not receive GUPPY, snorkel, SSR, SSG or other special conversions. Little is recorded about this "Queenfish Modification" that was a household word for submariners in the '50s.
