IJN Hyuga (CVB-1916(1942-mod)


Return to Japanese Navy page:


The Japanese were probably some of the first to realise that the days of the battleships were over. The Japanese older ships were all put through a program of rebuilding and enhancements through the 1930's and up to the start of the Western Foreign War. The Hyuga's were due for their next regeneration when the IJN decided it would transform the ships into hybrid battlecarriers.

The ships were fitted with a full width, 485 foot flight deck, from B turret to the aft part of the ship. A double height hangar was fitted to take 35-40 aircraft. In most cases the ships were filled with Zero fighters for fleet protection. The four turrets removed were fitted to a new battlecruiser.

My drawing was done to suit what I was trying to create, which was the hybrid battle/carrier that could support the landing forces that would run rampant through the Pacific and Indian Oceans 1942-43. In real life there were several drawings done as to what conversions of the ships could be. The seaplane version is the one that was actually proceeded with.

Another design that was proposed.

Ise as a full carrier conversion. Conversion based on the Taiho class carriers.
