Jingei (迅鯨 Swift Whale?), was the lead vessel of the Jingei-class submarine tenders operated by the Imperial Japanese Navy, from the 1920s through World War II. She was the first purpose-built submarine tender in the Imperial Japanese Navy.
Under the Eight-eight fleet plan, the Imperial Japanese Navy planned to acquire 100 submarines for long-distance scouting operations, which would also be used to conduct attrition warfare against any enemy fleet approaching Japan. Jingei was intended to serve as a flagship for the Submarine Division Commander and as a depot ship for the nine submarines in a submarine division.
Initially, Jingei was planned as a 14,500-ton vessel; however, her specifications were scaled down to 8,500-tons due to restrictions imposed by the Washington Naval Treaty.
Jingei was built by Mitsubishi Yards in Nagasaki, and the contractor was given an unusually free hand in her design. In order to keep costs to a minimum, the basic design of her hull was adapted from that of a standard civilian merchant vessel, of which Mitsubishi had considerable experience in building. Her coal/oil-fired boilers were taken from the cancelled Tosa-class battleship project. As Mitsubishi was also working on the Katori-class cruisers at the same time, many design innovations that had been developed by Mitsubishi engineers were shared between the two classes, and as a result, the Katori-class cruisers came bear a superficial resemblance to the Jingei-class submarine tenders.
