ww2dbaseSargo-class submarine Spearfish was laid down on 9 Sep 1937 at the Electric Boat Company in Groton, Connecticut, United States. The boat was launched on 29 Oct 1938 with Mrs. Lillian Spear as sponsor, wife of the Electric Boat Company president. USS Spearfish was commissioned on 17 Jul 1939 at New London, Connecticut with Lieutenant Charles E. Tolman, Jr., in command. The submarine shifted to the Pacific in 1940 and arrived in the Philippines on 8 Nov 1941.
ww2dbaseOn 8 Dec 1941, just seventeen hours after bombs fell on Pearl Harbor, Spearfish departed Corregidor in the Philippines on her first war patrol. Her assignment was to patrol the South China Sea and the approaches to Saigon, French Indochina (now Ho Chi Minh City, Vietnam). She fired her first shots of the war on 20 Dec 1941 when she launched four torpedoes at three Japanese submarines off Cam Ranh Bay with no hits. On 8 Jan 1942, Spearfish shifted to the Dutch East Indies (now Indonesia) and at the end of that month, ended her first war patrol at Soerabaja (now Surabaya) in East Java, Dutch East Indies.
ww2dbaseSpearfish patrolled the Dutch East Indies on her second war patrol and drew her first blood in the Philippines on her third patrol when, on 17 Apr 1942 off Panay, Spearfish torpedoed and sank a 5,000-ton Japanese transport ship. She severely damaged a similar ship a week later north of Lingayen Gulf. On 3 May 1942, Spearfish evacuated 27 military, nursing, and civilian personnel from the island of Corregidor in Manila Bay, Philippines only hours before the island fell to the Japanese. Spearfish delivered the evacuees to Fremantle, Australia on 20 May 1942.
ww2dbaseSpearfish's fourth war patrol took her back to French Indochina. On 27 Jul 1942 off Cam Ranh Bay, she torpedoed and badly damaged the 9,500-ton Japanese submarine repair ship Rio de Janeiro Maru. Postwar analysis officially credited Spearfish with sinking this ship but, in fact, Rio de Janeiro Maru survived and was repaired. Spearfish's fifth war patrol took her back to the Philippines. On 24 Sep 1942, Spearfish torpedoed and sank a 3,000-ton Japanese minelayer south of Mindoro. Two weeks later, Spearfish intercepted her first convoy off northern Luzon where she fired three torpedoes at the 7,000-ton cargo ship Tottori Maru. Lookouts aboard the freighter saw the tracks of the approaching torpedoes and the ship was able to turn out of their path. These torpedo misses were not such a bad thing, however, because the Tottori Maru was carrying 1,961 Allied prisoners-of-war from camps on Luzon and Mindanao. Some of these prisoners were survivors of the "Bataan Death March" and others were captured on Corregidor. Spearfish ended her fifth war patrol at Brisbane, Australia.
ww2dbaseFor her sixth war patrol, Spearfish patrolled the Bismarck Sea and the approaches to Rabaul, New Britain. On 12 Dec 1942, she tracked a task force of warships consisting of two heavy cruisers and three destroyers. Spearfish tried to gain a position of advantage but the warships were too fast and continued on their mission without ever knowing Spearfish was there. She sighted many other ships during this patrol, damaging two, but was distracted by six different sightings of the same properly marked hospital ship. Spearfish ended this patrol at Pearl Harbor, Hawai'i.
ww2dbaseAfter an overhaul and change of command at Mare Island Naval Shipyard in California, Spearfish sailed on her seventh war patrol to the approaches north of Truk in the Caroline Islands. On 21 Jun 1943, she detected her second task force of major warships. This time, the formation was made up of three aircraft carriers, two battleships, one cruiser, and several destroyers. Spearfish was able to fire her torpedoes this time but scored no hits and, again, the Japanese warships sailed on with no indication they were ever aware of the submarine's presence. She ended this patrol at Midway on 1 Aug 1943.
ww2dbaseSpearfish's eighth war patrol took her to southern Japan and the approaches to the Bungo Channel. On 11 Sep 1943, after sighting a Japanese convoy, Spearfish maneuvered into the very center of the formation of ships. Within a span of four-and-a-half minutes, Spearfish fired eight torpedoes at four different ships from both her bow and stern tubes. Two torpedoes hit and sunk one freighter and one torpedo hit transport ship Tsuyama Maru but did not explode. This ship was so damaged by the dud, however, that she went dead in the water and was later taken under tow. Almost immediately after the attack, Spearfish was subjected to a depth charge pounding that kept her submerged for 22 hours. Five days later, Spearfish located another convoy departing the Bungo Channel. After stalking that convoy for a day and a half, Spearfish fired eight torpedoes at three different ships with five hits. One 7,000-ton cargo ship was nearly broken in two before sinking and two others were badly damaged. Spearfish ended this war patrol at Pearl Harbor.
ww2dbaseSpearfish's next patrol was almost entirely a reconnaissance mission to the Marshall Islands. Her primary focus was the Jaluit Atoll where Spearfish made a detailed close-range survey from all around the atoll. She also made less detailed surveys of the atolls of Mili, Wotje, and Maloelap.
ww2dbaseHer tenth patrol was to the shipping lanes leading to and from Formosa (Taiwan). On 30 Jan 1944, Spearfish attacked a convoy of large cargo ships, damaging the 7,000-ton freighter Tamashima Maru quite badly. After enduring a depth charge attack, Spearfish circled back to the damaged freighter. By this time, another cargo ship and one of the escorts had come alongside Tamashima Maru. Since night had fallen, Spearfish was able to make her approach on the surface and fired four additional torpedoes at the three ships huddled together. Three torpedoes exploded against Tamashima Maru's side setting off her cargo of high explosives. All three ships disintegrated in a brilliant flash of light. Starting on 10 Feb 1944, Spearfish attacked three different convoys over three consecutive days. Two ships were sunk and another two were damaged. Having expended all of her torpedoes, Spearfish began retiring toward Pearl Harbor.
ww2dbaseDuring her next patrol to the East China Sea, on 6 May 1944, Spearfish again attacked a convoy where her torpedoes set off a ship's cargo of munitions and the ship vanished before their eyes. A second munitions ship was also struck by Spearfish's torpedoes, though with less spectacular results.
ww2dbaseAfter another overhaul at Mare Island, Spearfish sailed on her twelfth and final war patrol, this time to the Bonin Islands. During this patrol, her first assignment was a secret mission to make close reconnaissance surveys of Iwo Jima and Minami Jima. After delivering the survey results to Saipan, Spearfish continued with her patrol where her assignment was to maintain a lifeguard station along the B-29 bomber routes. On 19 Dec 1944, Spearfish picked up seven USAAF aircrewmen from the downed B-29 Superfortress "Pee-Wee" after they had been in the water for 25 hours. While departing her patrol area, Spearfish came across a large sampan that appeared to be adrift. She took three Japanese prisoners aboard and sank the sampan with gunfire. She delivered the aircrewmen and the prisoners to Saipan before sailing toward Hawai'i.
ww2dbaseUpon Spearfish's arrival at Pearl Harbor on 24 Jan 1945, she was relieved of further war patrols. For the remainder of the war, she operated out of Pearl Harbor on training assignments. Shortly after the end of hostilities, Spearfish sailed to California where she was promptly deemed to be so tired and worn out that she was recommended for immediate scrapping. Spearfish was laid up with the reserve fleet until she was decommissioned on 22 Jun 1946 before being scrapped in Oct 1947.
ww2dbaseSpearfish served throughout World War II and completed twelve war patrols, including one that began when the war was only hours old. She was officially credited with sinking 75,000 tons of shipping and damaging another 62,600 tons. She was authorized for the Submarine Combat Patrol Insignia five times and earned ten battle stars in World War II (the Submarine Combat Patrol Insignia was not created until after Spearfish's sixth war patrol, so she only made one patrol, her 7th, where she was denied the insignia).

2 Dec 1942 | Submarine USS Spearfish departed Brisbane, Australia, on her sixth war patrol bound for the Bismarck Islands. |
12 Dec 1942 | While on station in the Ysabel Channel just north of the Bismarck Sea, submarine USS Spearfish identified two Japanese Mogami-class heavy cruisers and three destroyers on a westerly course but the warships were able to outrun the slower submarine. These were the cruisers Suzuya and Kumano making a troop transport run from Kavieng to Manus. |
14 Dec 1942 | Submarine USS Spearfish had two false alarms this day. First, after stalking a large unescorted ship for over an hour south of New Hanover and almost at the point of firing torpedoes, the ship was identified as a properly marked hospital ship and was allowed to pass. Later, Spearfish stalked a single-stack ship for 20 minutes before identifying it as a large floating tree trunk with a branch extending 20 feet into the air. |
16 Dec 1942 | Submarine USS Spearfish spent an hour stalking an unescorted ship south of New Hanover only to recognize it as the same properly marked hospital ship Spearfish wasted an hour stalking two days earlier 40 miles away. Again, the ship was allowed to pass. |
18 Dec 1942 | While patrolling in the Bismarck Sea, submarine USS Spearfish detected a large ship running with lights in the early morning darkness. This time it only took 30 minutes to identify the ship as the same properly marked hospital ship seen two days earlier and four days earlier. |
25 Dec 1942 | Submarine USS Spearfish detected two Japanese cargo ships steaming in the Bismarck Sea. Spearfish fired four torpedoes with unobserved results, although postwar analysis credited Spearfish with two 7,000-ton cargo ships damaged. |
27 Dec 1942 | Submarine USS Spearfish made her fourth sighting of the properly marked hospital ship apparently on scheduled runs between Rabaul and Manus. The ship was allowed to pass. |
31 Dec 1942 | Submarine USS Spearfish tracked a convoy of two cargo ships and one tanker in the Bismarck Sea but was unable to gain an advantageous firing position. |
2 Jan 1943 | Submarine USS Spearfish fired four torpedoes at a convoy of two Japanese cargo ships in the Bismarck Sea, damaging Japanese army cargo ship Akagisan Maru. |
9 Jan 1943 | Submarine USS Spearfish made her fifth sighting of the properly marked hospital ship over the previous three weeks. The ship was allowed to pass. |
12 Jan 1943 | As Submarine USS Spearfish was departing her assigned patrol area to return to base, she made one more sighting of the properly marked hospital ship. |

21 Jun 1943 | 170 miles northwest of the Japanese base at Truk, submarine USS Spearfish detected a formation of 11 to 13 Japanese warships, including the carriers Ryuho, Unyo, and Chuyo, battleships Kongo and Haruna, cruiser Kumano, plus destroyers. The task force steamed directly over Spearfish and when the submarine was in the middle of the formation, she fired four torpedoes at the lead carrier but missed. While setting up for a shot at the second carrier, Spearfish was forced to go deep by an approaching cruiser on a collision course. The Japanese task force arrived safely at Truk later that same day without ever detecting Spearfish's presence. |
28 Jun 1943 | Sixty miles northeast of Truk, submarine USS Spearfish attacked a convoy of four freighters plus an escort. Spearfish fired three torpedoes with no hits. |
12 Jul 1943 | Twenty-five miles southwest of Eniwetok, submarine USS Spearfish fired three torpedoes at a Japanese destroyer with no hits. |
28 Jul 1943 | Submarine USS Spearfish departed her patrol area bound for Midway. |

6 Sep 1943 | Submarine USS Spearfish entered her patrol area off the east coast of Kyushu, Japan. |
9 Sep 1943 | Shortly after dawn, submarine USS Spearfish avoided two torpedoes fired at her from a Chidori-class torpedo boat. |
11 Sep 1943 | After sighting a Japanese convoy of seven freighters, one destroyer, and three torpedo boats 90 miles southeast of Kyushu, submarine USS Spearfish maneuvered into the very center of the convoy. Within a span of four-and-a-half minutes, Spearfish fired eight torpedoes at four different ships. Four or five of the torpedoes missed, one was a hit but did not explode, and two definitely exploded. One 7,000-ton freighter was sunk and another, Army transport ship Tsuyama Maru, was so damaged by the dud that she went dead in the water. Spearfish was subjected to a depth charge attack that kept her submerged for 22 hours. The Tsuyama Maru was later towed to port and repaired. |
16 Sep 1943 | After making repairs following a depth charge attack four days earlier, submarine USS Spearfish located a Japanese convoy of seven freighters and three escorts departing the Bungo Channel. |
18 Sep 1943 | After stalking a Japanese convoy for a day and a half covering 230 miles, submarine USS Spearfish fired eight torpedoes at three different ships and scored five hits. One 7,000-ton cargo ship sank after nearly being broken in two. Two 5,500-ton freighters were badly damaged and possibly sunk. Spearfish was able to evade the ensuing depth charge attack without damage. |
29 Sep 1943 | 120 miles southeast of the Bungo Channel, submarine USS Spearfish detected a convoy of two large 12,000-ton passenger/troop ships and three escorts. Spearfish fired her last four operable torpedoes with unobserved results. With all of her torpedoes expended, Spearfish departed her patrol area bound for Midway. |
4 Oct 1943 | While on her way to Midway, submarine USS Spearfish dove upon sighting an aircraft. At a depth of 200 feet, three depth bombs exploded above Spearfish causing no damage. |
7 Oct 1943 | Submarine USS Spearfish arrived at Midway. |
8 Oct 1943 | Submarine USS Spearfish departed Midway bound for Pearl Harbor, Hawai'i. |

18 Nov 1943 | Submarine USS Spearfish began a close reconnaissance survey of the Jaluit Atoll in the Marshall Islands. |
20 Nov 1943 | While making a submerged reconnaissance survey of Jaluit Atoll, submarine USS Spearfish suffered a fire in the main control cubicle resulting in the boat losing all electrical power. The submarine began to sink while frantic repairs were begun. At a depth of 150 feet, power was restored and Spearfish was able to return to periscope depth. |
29 Nov 1943 | Submarine USS Spearfish departed Jaluit Atoll bound for Mili Atoll, Marshall Islands. |
30 Nov 1943 | Submarine USS Spearfish arrived off Mili Atoll, Marshall Islands and began a close reconnaissance survey of the atoll. |

4 Dec 1943 | Submarine USS Spearfish arrived at her rescue station 40 miles east of Wotje Atoll. Spearfish was expecting a US carrier raid on Wotje on Dec 5 or 6 but the raid actually took place Dec 4 before Spearfish arrived on station. |
6 Dec 1943 | Submarine USS Spearfish departed Wotje bound for Maloelap Atoll. |
7 Dec 1943 | Submarine USS Spearfish arrived off Maloelap Atoll, Marshall Islands and began a close reconnaissance survey of the atoll, returning to Jaluit later in the day. |
13 Dec 1943 | According to orders, submarine USS Spearfish departed her patrol area bound for Pearl Harbor, Hawai'i. |
19 Dec 1943 | Submarine USS Spearfish arrived at Pearl Harbor, Hawai'i and concluded her ninth war patrol. |

19 Jan 1944 | Submarine USS Spearfish stopped briefly at Johnston Island to top off her fuel tanks before resuming her tenth war patrol. |
30 Jan 1944 | 470 miles northeast of Saipan, submarine USS Spearfish intercepted a Japanese convoy of three cargo ships and two escorts. Spearfish fired four torpedoes with two hits that caused the 7,000-ton freighter Tamashima Maru to go dead in the water. Spearfish then endured a three-hour depth charge attack that expended 46 depth charges. Eleven hours after the first attack, Spearfish approached the stricken cargo ship well after dark. Another cargo ship from the original convoy had come alongside Tamashima Maru, presumably to pass a tow line, and one of the escorts was alongside as well. Spearfish made surface attack and fired four more torpedoes at the overlapping ships. Three explosions set off Tamashima Maru's cargo of ammunition and all three ships disintegrated as Spearfish bridge personnel watched. |
7 Feb 1944 | Submarine USS Spearfish transited the Bashi Channel and entered the South China Sea. |
10 Feb 1944 | At the southern edge of the Taiwan Strait, submarine USS Spearfish intercepted a Japanese convoy consisting of one large troop transport, three medium-sized cargo ships, and three escorts. Spearfish fire four torpedoes at the troop transport with two hits. One of the torpedoes that missed went on and struck the cargo ship Tatsuwa Maru. The troop ship sank within minutes while Tatsuwa Maru was only damaged. |
11 Feb 1944 | As the Submarine USS Spearfish withdrew from the convoy she had attacked the day before, she ran into a different Japanese convoy of eleven ships. Spearfish fired four torpedoes at one of the merchant ships with one hit. The extent of damage was not observed. |
12 Feb 1944 | For the third day in a row, submarine USS Spearfish came upon a Japanese convoy. This one was made up of four cargo ships and two escorts. Spearfish fired four torpedoes at one of the cargo ships with two hits. The results were not observed but all indications were that the ship sank. With no more torpedoes remaining, Spearfish set a course for Midway. |
14 Feb 1944 | Submarine USS Spearfish transited the Bashi Channel and departed the South China Sea. |
29 Feb 1944 | After having been redirected from Midway to Pearl Harbor, submarine USS Spearfish arrived at Pearl Harbor, Hawai'i and ended her tenth war patrol. |
31 Mar 1944 | After a refit that concentrated on her main engines, submarine USS Spearfish departed Pearl Harbor, Hawai'i on her eleventh war patrol. |
