USS Haddock ( SS - 231 ) , a " Gato " - class submarine , was the second submarine of the United States Navy to be named for the haddock , a small edible Atlantic fish , related to the cod . A previous submarine had been named " Haddock " ( SS - 32 ) , but was renamed " K - 1 " prior to her launching , so " Haddock " ( SS - 231 ) was the first to actually bear the name . " Haddock " ( SS - 231 ) was laid down at the Portsmouth Navy Yard on 31 March 1941 . She was launched on 20 October 1941 ( sponsored by Mrs . William H . Allen ) , and commissioned on 14 March 1942 , Lieutenant Commander Arthur H . Taylor ( Class of 1927 ) in command . First war patrol , July – September 1942 . After shakedown and training cruises off New England , " Haddock " sailed for the $ 3 on 19 June 1942 and arrived Pearl Harbor 16 July . She departed on her first war patrol on 28 July , the first submarine to do so with the new SJ radar . This equipment added greatly to her power in seeking out and destroying enemy ships in darkness or reduced visibility . Penetrating into the Bonin Islands – East China Sea area , " Haddock " attacked a freighter on the surface on 12 August , damaged her , and next day sank an unidentified transport of about 4 , 000 tons . In the Formosa Straits on 26 August " Haddock " fired four stern shots at " Teinshum Maru " but missed ; the submarine swung around to bring her bow tubes to bear and sent the target to the bottom . " Haddock " patrolled off Okinawa before returning to Midway 19 September 1942 . Second , third , and fourth war patrols , October 1942 – April 1943 . " Haddock " ' s second war patrol , commencing 11 October from Midway , was carried out in the Yellow Sea . After two attacks without hits , the submarine torpedoed " Tekkai Maru " amidships on 3 November , breaking her in two . She was forced to break off another attack on 6 November because of destroyers and search aircraft , but during the night of 11 – 12 November blew off the stern of cargo ship " Venice Maru " east of the island of Honshū . " Haddock " damaged another ship on 13 November , only to be prevented from finishing her off by escort craft , and she expended her last torpedo on an empty tanker on 16 November . After a brief gunfire duel with her victim , the submarine headed for Pearl Harbor , arriving on 4 December . " Haddock " departed Pearl Harbor on 28 December on her third war patrol , this time to the oceans south of Japan . She was attacked by two destroyer s raining depth charge s , and when she finally surfaced to clear the area , " Haddock " found herself surrounded by Japanese patrol craft . The submarine sped out of the trap just in time to avoid destruction . A few days later , 17 January 1943 , she sank an unidentified freighter of 4 , 000 tons , and on 19 January " Haddock " detected six cargo vessels steaming in double column . Gaining attack position on the last ship , she scored two hits and sent her to the bottom . Aerial attack and depth charges kept her from bagging the other members of the convoy and bad weather forced " Haddock " to return to Midway on 17 February . " Haddock " cleared Midway on 11 March for her fourth war patrol , and saw her first action on 3 April off Palau , when she encountered a transport protected by a corvette . The submarine launched two " fish " at the corvette , but the torpedoes apparently ran under without exploding . " Haddock " then turned her attention to the transport and succeeded in sinking her with a spread of torpedoes . Following the torpedo tracks , the persistent corvette dropped 24 depth charges , many directly over " Haddock " , damaging her conning tower and radar . After spending some time patrolling off Saipan , she returned to Pearl Harbor on 19 April 1943 . Fifth , sixth , and seventh war patrols , June – November 1943 . Setting out from Pearl Harbor again on 30 June , " Haddock " set course for the Caroline Islands on her fifth war patrol . Detecting a group of four escorted transports north of Palau on 21 July , she maneuvered into position and sank " Saipan Maru " . The depth charge attacks of the accompanying ships were ineffective . That same day " Haddock " came upon two unescorted tankers . Her first attack failed to sink the two ships , but she followed the ships and made two more attacks before finally breaking off the action for lack of torpedoes . " Haddock " arrived at Midway on 6 August and at Pearl Harbor four days later . " Haddock " ' s sixth war patrol was conducted in waters off Truk , the vital Japanese base in the Carolines . Departing Pearl Harbor on 2 September , she torpedoed " Samsei Maru " on 15 September but failed to sink her , and the victim turned to ram the submarine . " Haddock " damaged seaplane tender " Notoro " on 20 September and then spent a harrowing day eluding the attacks of Japanese escort vessels alerted by the explosions . She returned to Midway on 28 September with all torpedoes expended . The veteran submarine departed on her seventh war patrol on 20 October 1943 and headed again for the waters off Truk . Late on 1 November , " Haddock " damaged two transports , barely surviving the attacks of a hunter - killer group a few hours later . She made one additional attack the next day , heavily damaging " Hoyo Maru " , before returning to Pearl Harbor on 15 November 1943 . Eighth and ninth war patrols , December 1943 – May 1944 . For her eighth war patrol " Haddock " joined a coordinated attack group with and . She departed Pearl Harbor on 14 December and rendezvoused on 17 December . Encountering a group of warships on 19 January , " Haddock " attacked escort carrier " Unyo " and damaged her severely before being driven off by the flattop ' s screening vessels . The submarine returned to Pearl Harbor on 5 February 1944 . " Haddock " departed for her ninth war patrol 10 March . Under the USN ' s relentless attack , spearheaded by the submarines , Japan ' s sea lifelines had shrunk to a trickle and targets were scarce , but " Haddock " succeeded in sinking a small escort vessel on 24 April , before returning to Pearl Harbor on 10 May 1944 . Tenth and eleventh war patrols , October 1944 – March 1945 . Her tenth war patrol was eventful as the Pacific war drew close to its climax . With Commander Roach in " Haddock " commanding , she formed an attack group with and , departing Pearl Harbor on 8 October . Moving to support the invasion of the Philippines , the submarines were present during the battle off Cape Engaño , part of the epochal Battle for Leyte Gulf , on 25 October and unsuccessfully pursued some of the retiring Japanese units . Bothered by a malfunctioning periscope , " Haddock " scored no hits on the rest of her patrol and returned to Pearl Harbor on 10 December . Fitted out with extra deck guns for her eleventh war patrol , " Haddock " sailed in company with submarines and for the seas east of Japan . The boats made a diversionary sweep designed to pull early warning craft away from the intended track of a carrier group " en route " for air strikes against Tokyo . Gaining their objective with complete success , the submarines attacked the picket boats with gunfire , allowed them to send contact reports , and then sank several , diverting Japanese efforts away from the undetected carrier group . " Haddock " returned to Guam on 14 March 1945 . Last war patrols , April – August 1945 . " Haddock " spent her twelfth and thirteenth war patrols on lifeguard station near Tokyo , standing by to rescue downed airmen after raids on Japanese cities . This duty occupied her from April until her return to Pearl Harbor on 22 August . The hard fought victory , to which she had contributed so much , was won . " Haddock " departed for the East Coast of the United States on 7 September and after transiting the Panama Canal and visiting various ports on the East Coast , arrived at New London , Conn . , on 29 March 1946 , nearly four years after she had sailed from the North Atlantic to victory . She was placed in reserve in commission on 20 April and decommissioned on 12 February 1947 . In August 1948 " Haddock " was assigned duty as a reserve training ship for 6th Naval District , and served in that capacity until being again placed out of service at New London in May 1952 . She was again assigned to reserve training , this time at Portsmouth , N . H . , June 1956 , and finally was struck from the Naval Vessel Register and sold for scrap to Jacob Checkoway on 23 August 1960 . " Haddock " received 11 battle star s for her service in World War II . All of her war patrols except the twelfth were designated successful and she received the Presidential Unit Citation for her outstanding performance on the second , fifth , sixth , and seventh war patrols .
