Source-derived summary

Yu 1007 was an Imperial Japanese Army transport submarine of the Yu 1001 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, although one source 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 1007 a unit of the Yu 1001 subclass.

Japan Steel Works (Nihon Seikojo) constructed Yu 1007 at its plant in Hiroshima, Japan. Records of the details of the construction of Yu 1007 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.

Service history

Editorial analysis

Why this record matters

“Japanese submarine Yu 1007” is worth following because a concise public description often conceals a longer documentary argument. Here, Japanese, submarine and imperial provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 16, 2025. The linked authority identifier is Q112169093. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1007, 1001, 1943 and 1944.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
