Sub History
Built in Portsmouth Naval Shipyard, New Hampshire. Laid down March 15, 1943 as a Balao Class Fleet Submarine. USS Pampanito (SS-383) and USS Picuda (SS-382) were the first two of ten submarines built in the new shipbuilding basin. Launched July 12, 1943 as USS Pampanito (SS-383). Commissioned November 6, 1943 in the U.S. Navy (USN) with Lieutenant Commander Charles B. Jackson, Jr. in command. After shakedown off New London, Connecticut transits the Panama Canal to Pearl Harbor arriving February 14, 1944.

Wartime History
In total, Pampanito made six war patrols in the Pacific. In total, she sank six Japanese ships and damaged four others.

First War Patrol
Her first war patrol, from March 15 to May 2 was conducted in the southwest approaches to Saipan and Guam. She served on lifeguard duty south of Yap, then scored two torpedo hits on a destroyer before sailing for Midway Island and Pearl Harbor for refit and repairs to a hull badly damaged by depth charges.

Second War Patrol
Pampanito's second war patrol, from June 3 to July 23 off Kyūshū, Shikoku, and Honshū. On 23 June, a submerged Japanese submarine fired two torpedoes, just missing Pampanito. On 6 July, Pampanito damaged a Japanese gunboat, and 11 days later headed for Midway Island.

Third War Patrol
Pampanito's third war patrol, from August 17 to September 28, was part of a "wolfpack" operation with submarines USS Growler (SS-215) and USS Sealion (SS-315) in the South China Sea.

On September 12, 1944 a US submarine wolf pack including USS Sealion (SS-315), USS Barb (SS-220), USS Queenfish (SS-393), USS Pampanito (SS-383) and USS Growler (SS-215) attack a convoy bound from Straits Settlement for Japan. She sank 10,509 ton POW ship Kachidoki Maru carrying 900 British prisoners, the 5,135 ton tanker Zuihō Maru, and damaged a third ship.

On September 15, the attacking submarines were notified that Allied prisoners were found among the wreckage from the Rakyo Maru and Pampanito traveled at top speed back to the scene of the sinking, arriving five days later. Finding men clinging to makeshift rafts, Pampanito was able to pick up 73 British and Australian survivors and called in three other subs, USS Sealion, USS Barb (SS-220) and USS Queenfish (SS-393), to assist with the rescue. She then set course for Saipan, disembarked the survivors, and returned to Pearl Harbor.

Fourth War Patrol
Pampanito's fourth war patrol, from 28 October to 30 December, took place off Formosa and the coast of southeastern China with Sea Cat (SS-399), Pipefish (SS-388), and Searaven (SS-196).
