Project history

Kaidai 3b (Large Admiralty 3b) type. Built under the 1923-1928 programme. Should become repetition of Kaidai 3 type, however during trials of a lead submarine of this type I53 a number of constructive lacks, such as insufficient stability and vibration on high speed has been revealed. Besides submarine was not possible to reach design 22kts. For lacks correction designers brought a number of changes into design: the hull was lengthened, its lines were a little changed, size of CT was moderated. After that design was renamed as Kaidai 3b (boats of first series began to be called Kaidai 3а).
