Testing a 70,000-ton battleship's speed claim

Could a roughly 70,000-ton Vermont-style battleship reach 27 knots with only 68,000 shaft horsepower?

Probably not. The claimed performance would require an unusually efficient hull, and the Tillman-derived forms were not forgiving enough to make that combination credible.

The game specification proposes a 70,000-ton Vermont reaching 27 knots on 68,000 shaft horsepower. Real cruisers could weigh less, use more power, and still fall short of that speed. No full calculation is offered, so the answer is a plausibility judgment about the hull form. The Tillman-derived shape would need exceptionally low resistance to make the figures credible, and it is judged insufficiently forgiving for that combination.
