On October 28, 1944, Sea Cat began her World War II service in the Pacific Fleet.  She spent three patrols in the South China, East China, and Yellow Seas.  August 1945, the submarine began her fourth war patrol off the Kuril Islands, but upon arrival the crew learned that the war had ended.  Sea Cat was ordered to proceed to the Japanese home islands to participate in the formal surrender ceremony in Tokyo Bay.

After the war, Sea Cat served in Guam and San Diego before being overhauled in Mare Island in April of 1946.  The submarine’s overhaul was completed in 3 months.  She then began her first simulated war patrol out of San Diego in August of 1946.  During this patrol Sea Cat visited Hawaii, Canton Islands, Samoa Island, and Shanghai.

After the simulated war patrol in the Pacific Fleet, Sea Cat was transferred to the Atlantic Fleet out of Balboa, Panama, from 1947 to spring of 1949.  The submarine’s home port was changed to Key West in June of 1949.  Later that year, Sea Cat was overhauled and redesignated as an auxiliary submarine (AGSS 399) with experimental changes made to the boat’s design.  The modifications and repairs were made by the Philadelphia Naval Shipyard for four months.  She operated out of Key West from 1950 through 1951.

January of 1952, Sea Cat arrived in Philadelphia again for another overhaul.  This time she was converted to a Fleet Snorkel Submarine and redesignated back to SS 399.  June 26, 1952, the submarine departed Philadelphia and returned to Key West.  The next sixteen years, Sea Cat served out of Key West.  Her patrols were spent in the Caribbean, the Gulf of Mexico, and once in the Mediterranean in 1966.

The Electric Boat Company laid Gato's keel on October 5, 1940.  She was launched in Groton, Connecticut, on August 21, 1941, and was commissioned into the United States Navy December 31, 1941.  Her first war patrol began in the Pacific on April 20, 1942.

During World War II, Gato completed thirteen war patrols.  Her first five patrols she served off the coast of the Marshall Islands, Kurile Islands, Kiska, Truk atoll, Solomon Islands, and Gilbert Islands.

The modifications made to Gato, included installation of new freestanding mast for SD radar and relocation of SJ to a new mast supported by her periscope shears.   January 1945, Gato returned to war for her eleventh patrol.  The rest of the war she patrolled the Yellow Sea, off the coat of Okinawa, and the coast of Wake Island.  While serving lifeguard duty during air strikes on Wake Island, "Cease Fire" was received aboard the submarine.  Gato was able to be apart of the formal surrender ceremony by the Empire of Japan on September 2, 1945.

After World War II, Gato was sent to the New York Naval Shipyard.  She was decommissioned on March 16, 1946.  She did serve as a Naval Reserve training ship at New York and Baltimore, Maryland.  March 1, 1960, her name was stricken from the Naval Register.  The Northern Metals Company of Philadelphia, Pennsylvania, bought Gato for scrapping on July 25, 1960.

Gato actively served  in the United States Navy for four years, 3 months, and 16 days.  During that time she earned 13 battle stars and Presidential Unit Citation for her service in World War II.

An American syndicated anthology television series, The Silent Service, aired from 1957 to 1958. This series was based on actual events about submarine service in the United States Navy.  The series finale focused on the service of Gato.  The episode "Five Ring Circus" tells the story of when a Japanese depth charge landed on the deck of the boat without exploding.  The episode can be viewed on Youtube at https://www.youtube.com/watch?v=ngb5_JChxac.
