What the Kii class would have added to Japan's battle fleet

How much of a game changer would the Kii-class battleships have been?

Not revolutionary, but fast and heavily armed enough to be a major threat and a powerful status asset for Japan.

The proposed Kii class combines a ten-gun 16-inch battery with a speed of about 29.75 knots. That gives a seven- to nine-knot margin over much of the American battle line in this comparison. Those characteristics would make it a dangerous opponent without making the design revolutionary. Bringing the class into service would also carry considerable prestige for Japan.
