The scale of a twenty-one-gun battleship

How large would an Archer-style battleship with seven triple 16-inch turrets be?

Roughly 55,000 to 60,000 tons for a ship carrying twenty-one 16-inch guns.

The design places seven triple 16-inch turrets along an Archer-like layout, for twenty-one heavy guns. Displacement would reach roughly 55,000 to 60,000 tons. The turrets, magazines, armor, and hull length needed to support them dominate the ship's scale. Its broadside would be immense, but the estimate makes clear that gun count cannot be added without creating an exceptionally large capital ship.
