USSLST-31 was aUnited States NavyLST-1-classtank landing ship used exclusively in theAsiatic-Pacific Theater duringWorld War II. Like many of her class, she was not originally named and is properly referred to by her hull designation. Later she was named forAddison County, Vermont. She was the only US Naval vessel to bear the name.
LST-31 was laid down on 2 February 1943 atPittsburgh by theDravo Corporation;launched on 5 June 1943; sponsored by Mrs. Maurice Endres;[2] accepted by the Navy and placed in reduced commission on 10 July 1943; and sailed toNew Orleans, where she was placed in full commission on 21 July 1943.[3]
The new tank landing ship got underway on 29 July, forPanama City, Florida, where she conducted a series of beaching exercises.LST-31 returned to New Orleans, on 7 August, to take on cargo for transportation to thePacific. After a brief port call atGuantánamo Bay, Cuba, she transited thePanama Canal, on 24 August, and joined theUS Pacific Fleet. She then continued on toSan Diego, where she arrived on 13 September.[3]
After participating in beaching exercises in the San Diego area, the ship stopped atPort Hueneme, and atSan Francisco, to take on cargo. She left the west coast on 15 October, bound forHawaii, reachedPearl Harbor on 25 October, and began unloading. When this task was completed,LST-31 again weighed anchor on 5 November, and shaped a course for theGilbert Islands. As a member of 5th Amphibious Force, the ship was slated to take part in theassault on Makin Island.LST-31 arrived off Makin, on 20 November, and began discharging troops and cargo ashore. She remained off that atoll until 3 December, when she got underway to return to Pearl Harbor. Shortly after her arrival, the vessel entered thePearl Harbor Navy Yard for repairs and alterations. While her engines were being overhauled, additional40 mm (1.57 in) Bofors guns and20 mm (0.79 in) Oerlikon cannons were installed. The yard period ended in early January 1944, and the refurbished vessel then took part in training exercises offMaui, in preparation for the forthcoming invasion of theMarshall Islands.[3]
The tank landing ship left Pearl Harbor on 19 January and set a course forKwajalein. She anchored off that atoll on 1 February, and began discharging her cargo in support of operations in theMarshalls. On 12 February, the ship began embarking troops for theinvasion of Eniwetok and, five days later, sortied with LST Group 8. She beached at Eniwetok, on 20 February, and began landing her soldiers and discharging cargo ashore.LST-31 remained there until 20 March, when she got underway for Hawaii. She stopped en route at Kwajalein andTarawa, to take on cargo and passengers and finally reached Pearl Harbor on 15 April. Following repairs indry dock there, she resumed operations on 10 May, with a series of training exercises inHapuna Bay, Hawaii. On 25 May,LST-31 left Hawaiian waters, bound for Eniwetok. Upon her arrival at that atoll on 7 June, she refueled and took on cargo in preparation foroperations against Saipan. The vessel arrived off Saipan, on 14 June, and began discharging troops and supplies ashore. She cleared the area on 23 June, and returned to Eniwetok to replenish her cargo.[3]
LST-31 arrived back at Saipan on 17 July; unloaded supplies and small craft; and, during the next few weeks, served as ahospital ship. At night, she anchored off Saipan to receive casualties and was underway offTinian, during daylight hours. This assignment occupied the ship through 21 August, when she began a round-trip voyage to Eniwetok. After returning to Saipan, the vessel underwent three days of voyage repairs and got underway on 23 September, for thewest coast of the United States. En route, she touched at Eniwetok;Apamama and Makin Islands, Gilbert Islands; and Pearl Harbor. She left the latter port on 6 November, and reachedSan Francisco on 17 November 1944. After one day in port there,LST-31 sailed toSan Pedro, to enter theWest Coast Shipbuilding Company yards for extensive alterations and repairs.[3]
The ship left the yard in early February 1945, conducted sea trials, and arrived at theMare Island Navy Yard,Vallejo, California, on 18 February, to take on an amphibious craft. She then visitedSeattle for additional repair work. On 10 March, the vessel got underway for Hawaii and reached Pearl Harbor on 23 March.[3]
LST-31 left Hawaii on 4 April, forOkinawa. She embarked passengers and loaded supplies at Eniwetok andGuam, before proceeding on to theRyūkyūs, and anchoring in waters off southwestern Okinawa on 3 May. She remained in the area for approximately three weeks providing logistic support to troops fighting on Okinawa. The ship arrived atUlithi on 28 May; took on cargo; and, on 2 June, set a course for the island ofLeyte, in thePhilippines. During the months of June, July, and August,LST-31 operated between the Philippines and Okinawa, transporting supplies and troops between the two points to build up Okinawa as a base for the conquest of the Japanese home islands. However, this invasion was obviated whenJapan capitulated on 15 August. The ship then began moving occupation troops and equipment to Japan from various points in the Philippines. She first arrived in Japanese waters on 15 September, when she dropped anchor inTokyo Bay.[3]
On 30 November,LST-31 was assigned to duty in Japan with the 5th Fleet, Amphibious Group 11, LST Flotilla 35. However, these orders were superseded late in December; and the ship was slated for decommissioning. She was scheduled to be turned over to the Japanesemerchant marine to be manned by a Japanese crew under American control for use in repatriating Japanese citizens and shuttling supplies between Japanese ports.[3]
After the ship was stripped of all armament and other wartime equipment,LST-31 was decommissioned on 8 January 1946, and transferred to the Japanese. The vessel operated under Japanese control into May 1948, when she was returned to US Naval custody. She leftYokohama on 3 May, and shaped a course for the west coast of the United States. The tank landing ship was later berthed in the Seattle area. On 1 July 1955,LST-31 was namedAddison County. Her name was struck from theNaval Vessel Register on 11 August 1955, and she was subsequently sunk as a target.[3]
LST-31 earned fivebattle stars for her World War II service.[2]
