Project history

Kaichu (1) (medium Navy design No1) type. Designed in Japan in 1916 on the basis of Schneider-Laubeuf French submarines. In their construction peculiarities of Far East theatre for the first time have been considered. Submarines besides transverse bulkheads had longitudinal ones, that theoretically should raise their damage tolerance, but in practice it has made them only extremely tight and inconvenient for habitability. Diesels were delivered by Sulzer from neutral Switzerland. Double-hulled.

Boats of Kaidai 1 class as a whole have been recognised successful, however they have become operational already after the First World War.

Modernizations

None.

Naval service

No significant events.
