At the historical Dogger Bank, New Zealand and Indomitable were the two British ships with 12-inch guns. Their roughly 25-25.5-knot capability meant the faster ships had to leave them behind to close more quickly. A force built from the newer ships could instead operate at about 28 knots throughout. That would give it an estimated two-and-a-half-knot advantage over the German battlecruisers. Once caught within gun range, the Germans would have much more difficulty disengaging on their run home. A possible 15-inch Tiger would add firepower to that sustained pursuit.

Replacing the slow ships in the chase with modern battlecruisers lets the British close together and makes German disengagement harder.
