The KD2 design was loosely
based on the German U-139.
Launched in 1922 and completed in 1925, she had a double hull and good
surface speed for her day, and she became the basis for practically all
the later Japanese submarine designs.
additional KD2s were
planned, but construction was cancelled when Japan received seven
German U-boats as reparations from the First World War. The Japanese
wished to absorb all the lessons they could from the German boats
before beginning mass production of their own submarines.
