Peto was laid down on 18 June 1941 by the Manitowoc Shipbuilding Company, Manitowoc, Wisconsin; launched on 30 April 1942; sponsored by Mrs. E. A. Lofquist; and commissioned on 21 November 1942, Lieutenant Commander William T. Nelson in command.
World War II
Late in December 1942, Peto decommissioned, was loaded on a barge, and departed Manitowoc for New Orleans, Louisiana, the first submarine to traverse the mid-western waterways to reach New Orleans and the sea from the building yards. The ship recommissioned, completed fitting out and shakedown, sailed for the Panama Canal and arrived Brisbane, Australia 14 March 1943.
Peto departed Brisbane for her first war patrol on 2 April. The submarine reconnoitered Greenwich Island for shipping on the 13th without finding any targets. That night she proceeded toward the equator to cover the Truk-Kavieng route, arriving on station the next day. A south-bound, Truk-Rabaul convoy came into view on the morning of 17 April, consisting of two destroyers, two medium freighters, and one small auxiliary. However, before Peto attacked, the trailing destroyer detected the submarine and forced her to dive. She withstood nine depth charges without damage.
Peto departed on her second war patrol on 10 June. On 29 June, she fired two torpedoes at a small auxiliary. One torpedo hit near the bow, breaking the ship in two. On 7 July, she sighted an east-bound tanker similar to Nippon Maru with two escorting destroyers. Peto maneuvered and fired three torpedoes; two hits causing severe damage. She returned to Brisbane on 4 August.
On 1 September, Peto set out on her third war patrol, which was held in the area north of the Bismarck Archipelago. After reconnoitering Nauru Harbor, she patrolled the route between Truk and Nauru for five days without contact. Peto moved to the Truk-Kavieng-Rabaul traffic routes on 20 September, and two days later, sighted five escorted ships headed toward Rabaul. She lost her attack chance at the last moment when the enemy made a radical change of course. While Peto attempted to close for a night attack, an alert escort only 7,000 yd (6,400 m) away detected her. The enemy ship opened fire on the submarine, forcing her to crash dive.
From 24–26 September, Peto patrolled off the Admiralty Islands without contacts. On 1 October, Peto sighted three medium freighters with only one sub-chaser as escort, and fired six torpedoes, hitting two of the ships. Post-war investigation revealed that Tonei Maru and Kinkasan Maru were both sunk. Peto returned to Brisbane, Australia on 21 October.
Underway again on 14 November, she fueled at Tulagi, and set out for her patrol area 24 November. On 1 December, she sighted an enemy convoy consisting of two passengercargo vessels with three small escorts. She fired six torpedoes at Konei Maru, which broke up and sank. On 9 December, while firing on a ship in a convoy, her target apparently saw the torpedoes coming and turned toward them to avoid being hit. An escort then drove Peto down and administered a thorough depth charging.
On 2 February 1944, she set course for Tulagi, arriving there on 5 February for fuel before departing the following day for her patrol area. On 10 February Peto sailed to rendezvous with Cero.
On 19 February, she attacked a ship with three escorts and one of her torpedoes struck home. The target was immediately engulfed in black smoke and depth charges were heard in the distance. Peto surfaced and found the escorts depth charging Cero's position. After closing Cero slowly, she fired two rounds from her 3 in (76 mm) deck gun at the escorts, and as the escorts returned the fire she withdrew, giving Cero a chance to escape unharmed.
On 23 February, Peto sailed for Langemak Bay to refuel and obtain spare parts, arriving on 27 February. On 1 March, she headed for her area again, and on 3 March made an unsuccessful attack on an enemy merchantman. The next day, she fired six torpedoes at a cargo ship and then went deep to listen as escorts were near. Two hits were heard, followed by a loud, deep explosion. Three minutes later breaking up noises were heard, and splashes from debris falling in the water could be heard for several minutes. The escorts dropped 13 depth charges before giving up. Peto had sunk Kayo Maru. On 16 March, Peto set course for Midway Atoll where she arrived on 25 March. She sailed on for Pearl Harbor the same day, arriving on 29 March.
On 28 April, Peto and Perch, along with an escort, sailed for her patrol area south of Formosa. She sailed from Midway on 2 May, with Perch and Picuda joining the wolf pack. Arriving in her area, Peto began looking for shipping worthy of her torpedoes. Only six ship contacts were made during the entire patrol and a favorable attack position could not be obtained on any due to aircraft in the vicinity or shallow water. She returned to Midway on 15 June and later that day sailed for Pearl Harbor with Kingfish, arriving on 19 June. On 21 June, she sailed on for San Francisco, California, for major alterations at the Bethlehem Steel Company yards.
On 29 September, Peto sailed westward again, reached Pearl Harbor on 7 October, and arrived Midway Island on 27 October, where she joined Spadefish and Sunfish. Task Group 17.13 arrived in their assigned area in the Yellow Sea 9 November.
On 12 November, Peto heard a loud explosion and saw a large flash. A burning ship with hull down was seen to the east and it was assumed Barb, which was also in the vicinity, had connected. Peto sent her crew to their battle stations and sent four torpedoes at the nearest ship of the convoy. Two hits were heard and the target slowed down and dropped back, though it didn’t stop. Peto fired her remaining two forward torpedoes at a second target and swung around to bring her stern tubes to bear. She fired four torpedoes at the third target. The torpedoes fired from the bow tubes struck home as the leading ship, Tatsuaki Maru, blew up and promptly sank. Two hits were heard on the third target and she was immediately engulfed in dense black smoke. Peto then scurried for cover, as it was getting light fast. She took her last look at the third target and noted that it was ablaze.
On 18 November, Peto made contact with one ship which was apparently lost and without an escort. She fired three torpedoes, the first hitting and setting the target ablaze. The second missed but the third hit and the target blew up and burned much brighter. Peto came around for a coup de grace but saw that it was unnecessary as only the stern of Aisakasan Maru was above the water, still burning like an inferno. She contacted another enemy ship, dead in the water with two escorts near, and sent three torpedoes streaking after the cargo ship. One torpedo hit the target and Chinkai Mara sank in four minutes. On 29 November, Peto attacked a small coastal tanker with her last torpedoes and she sailed for home.
Peto arrived at Guam on 6 December and underwent a refit before sailing for Pearl Harbor where she arrived on 2 January 1945. Peto departed from Pearl Harbor in company with Thresher, Shad, and Tilefish on 31 January, topped off at Saipan on 12 February, and headed for her patrol area the following day. However, she met no suitable targets on her 8th war patrol, and she returned to Midway on 9 April.
On 4 May, Peto got underway for her ninth war patrol. Off Marcus Island on 12 May, she guided friendly pilots to their targets. None of the planes were hit. On 21 May, Peto closed to the coast of Manus Island and took pictures of enemy shore installations. The next day, she headed for Guam arriving on 19 June.
On 14 July, she stood out on her tenth and last war patrol. On 24 July, she rescued two pilots from Lexington (CV-16), one with gunshot wounds in both legs. On 25 July her guns sank a sampan, and the same day she saved nine more downed aviators. On 10 August she picked up a Royal Navy pilot from Formidable.
On 15 August, Peto was assigned a life guard station to cover air strikes on the Japanese home islands, but hostilities ceased. The next day, Peto sailed for the Panama Canal Zone, arriving 15 September. On the 17th, she sailed for New Orleans, arriving on the 21st.
Peto joined the Atlantic Fleet and on 25 June 1946 was placed out of commission in reserve, berthed at New London, Conn. She remained in reserve until November 1956, when she became Naval Reserve Training submarine for the Eighth Naval District. She was struck from the Naval Vessel Register on 1 August 1960. She was sold for scrapping 10 November 1960.
