Yu 6 was an Imperial Japanese Army transport submarine of the Yu 1 subclass of the Yu I type. Constructed for use during the latter stages of World War II, she served in the waters of the Japanese archipelago.
Construction
In the final two years of World War II, the Imperial Japanese Army constructed transport submarines — officially the Type 3 submergence transport vehicle and known to the Japanese Army as the Maru Yu — with which to supply its isolated island garrisons in the Pacific. Only submarines of the Yu I type were completed and saw service. The Yu I type was produced in four subclasses, each produced by a different manufacturer and differing primarily in the design of their conning towers and details of their gun armament. None carried torpedoes or had torpedo tubes. Yu 6 was a unit of the Yu 1 subclass.[1]
The Hitachi Kasado Works (Hitachi Kasado Seisakujo) at Kudamatsu, Japan, constructed Yu 6.[1][2] Records of the details of the construction of Yu 6 have not been discovered, but the earlier Yu I-type submarines were laid down and launched during the latter half of 1943 and entered service at the end of 1943 or early in 1944.[2][3]
Service history
Yu 6 spent her operational career in Japanese home waters.[4] In January 1945, she was one of several Type I transport submarines sent to operate from Shimoda on the southern tip of the Izu Peninsula in Shizuoka Prefecture on Honshu.[2][4] She was assigned to Detachment 2, Transport Submarine Group, on 13 February 1945. The submarines began transport missions from Shimoda in March 1945, and during 1945 Yu 6 made a round-trip supply run from Shimoda to Hachijō-jima in the Philippine Sea.[2][4]
World War II ended with the cessation of hostilities on 15 August 1945. Yu 6 surrendered to the Allies later in August 1945.[2] She subsequently either was scuttled or scrapped.[4]
