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. The submarines of the Yu 2001 subclass notably differed from the other Yu I-type submarines in their "repose room,"[1] a deckhouse extending aft of the conning tower which gave the crew more room and greater comfort. None of the Yu I-type submarines carried torpedoes or had torpedo tubes. Yu 2001 was a unit of the Yu 2001 subclass.[1]
Ando Iron Works (Ando Tekkojo) constructed Yu 2001 in the Tsukishima district of Tokyo, Japan.[1][2] She was launched on 12 February 1944.
Service history
Yu 2001 spent her operational career in Japanese home waters.[1] Surviving records of the activities of Imperial Japanese Army submarines are fragmentary,[3][4] and no records have been discovered describing her specific activities in support of any particular operation.[2][1]
World War II ended with the cessation of hostilities on 15 August 1945.Yu 2001 surrendered to the Allies later in August 1945.[2] She subsequently either was scuttled or scrapped.[1]
