How a lighter Nelson design could reach 28 knots

Removing torpedo equipment, reducing the belt, and replacing the 6-inch battery with 4.7-inch guns could free enough weight and hull volume for a four-shaft Nelson capable of roughly 28 knots.

Question

How fast could a 35,000-ton Nelson be with a 12-inch belt, 4.7-inch secondary guns, and no torpedoes?

Short answer

A four-shaft design could probably make at least 28 knots because the lighter protection, secondary battery, and deleted torpedoes free space and weight for machinery.

Notes

The proposed Nelson retains its 16-inch main battery but trades away torpedo equipment, some belt thickness, and the heavier 6-inch secondary battery. Those changes release both displacement and internal volume for machinery. A four-shaft arrangement is the likely result. With that redistribution, the ship could plausibly exceed 28 knots while remaining near the 35,000-ton standard.
