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 3 was of the Yu 1 subclass.[1]

Service history
After her delivery to the Japanese Army, Yu 3 initially remained in Japanese home waters while the Army constructed additional submarines of her class and established a training program for their crews.[3] In May 1944, the Army created its first submarine combat unit (jissen butai), the Manila Underwater Transport Detachment (Manira Sensuiyuso Hakentai), consisting of Yu 3, her sister ships Yu 1 and Yu 2, and a mother ship.[3] The detachment got underway from Japan on either 28[3] or 30[2] May 1944 (according to different sources) bound for Manila on Luzon in the Philippines.[3] The vessels had a difficult voyage which included a number of mechanical breakdowns, but finally arrived at Manila on 18 July 1944.[2][3] After their arrival, the three submarines underwent repairs and thorough overhauls.[3]
On 20 October 1944, United States Army forces landed on Leyte, beginning both the Battle of Leyte and the broader Philippines campaign of 1944–1945.[3] In November 1944, all three submarines got underway on their first supply run to Leyte.[3] Yu 2 never arrived,[3] but Yu 1 and Yu 3 reached Ormoc on Leyte's west coast on 27 November 1944 and discharged a combined 600 bags of white rice, 50 boxes of field rations, and 300 boxes of radio batteries.[3]
In December 1944, Yu 1 and Yu 3 were sent to
