USS Amberjack (SS 522), a Tench-class submarine, was the second submarine of the United States Navy named for the amberjack, a vigorous sport fish found in the western Atlantic from New England to Brazil.

Her keel was laid down by the Boston Naval Shipyard of Boston, Massachusetts, on 8 February 1944. She was launched on 15 December 1944 sponsored by Mrs. Walter E. Lang, Jr., and commissioned on 4 March 1946, with Commander William B. Parham in command.

Following shakedown training in the West Indies and in the Gulf of Mexico, Amberjack reported on 17 June for duty with SubRon8. Operating out of the Submarine Base, New London, Connecticut, she conducted training missions in the North Atlantic, and, in November 1946, made a cruise above the Arctic Circle. In January 1947, the submarine entered the Portsmouth Naval Shipyard for extensive modifications and thereafter spent about a year undergoing a Greater Underwater Propulsion Power Program (GUPPY) conversion during which her hull and sail were streamlined and additional batteries and a snorkel were installed to increase her submerged speed endurance, and maneuverability. In January 1948, she reported for duty with SubRon4 based at Key West, Florida. She operated along the east coast and in the West Indies for a little more than 11 years. Her schedule included the development of tactics and independent ship exercises, type training, periodic overhauls, and fleet exercises. During this period, she also visited numerous Caribbean Sea ports. In July 1952, Amberjack was transferred to the newly established SubRon12, though she remained based at Key West and her employment continued as before.
