IJN Kasagi (CB-1938)


Return to Japanese Navy page:


The Kasagi class battlecruisers came about from the Japanese demilitarising several ships due to the Washington Treaty. Part of this stockpile was 8 twin 12" turrets which the Japanese felt could be used to arm 2 cruiser sized vessels more as armoured cruisers rather than the 'battlecruiser' tag they were given by the western powers. Two classes of this ship type were built, one with 12" and one with 10". Only the breadth dimension altered to allow for the bigger 12" barbette.

Designed to be fast, the ships had a good length to breadth hull ratio while extra heavy superstructures normally fitted to Japanese capital ships were kept to a minimum. They were big enough to be used as cruiser squadron flagships and gave the cruisers they acted with a ship of force.


As part of a 25,000 ton challenge I redrew the Kasagi with new armament, slightly longer hull and breadth dimensions (to take the triples so 9x12").
