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, although one source[1] states that the Yu 1001 subclass differed from the original Yu 1 sublcass in other ways, being longer, having a slightly larger displacement and more powerful diesel engine that increased the maximum speed by 2 knots (3.7 km/h; 2.3 mph), and probably having no deck gun installed. None of the Yu I-type submarines carried torpedoes or had torpedo tubes. Yu 1006 a unit of the Yu 1001 subclass.[2]
Japan Steel Works (Nihon Seikojo) constructed Yu 1006 at its plant in Hiroshima, Japan.[2][3] Records of the details of the construction of Yu 1006 have not been discovered, but the earliest Yu I-type submarines of the original Yu 1 subclass were laid down and launched during the latter half of 1943 and entered service at the end of 1943 or early in 1944.[3][4]
Service history
Yu 1006 spent her operational career in Japanese home waters.[1] Surviving records of the activities of Imperial Japanese Army submarines are fragmentary,[4][5] and no records have been discovered describing her specific activities in support of any particular operation.[1][3]
World War II ended with the cessation of hostilities on 15 August 1945. Yu 1006 surrendered to the Allies later in August 1945.[3] She subsequently either was scuttled or scrapped.[1]
