The J/CB/1914 battlecruiser design

The J/CB/1914 battlecruiser design is analogous to the J/BB/1914, except the battlecruiser version. One turret was sacrificed, but the armament is still 10-14in guns, as 8-14in is too light for such a large ship. Post 1918, "in the real world", they planned battlecruisers with 10-16in guns, so five turrets is not unprecedented for Japanese battlecruisers. The speed is rather low at 28 knots, but we can improve on that in later versions. This is the Springsharp report:
