Hood's machinery refit offers a choice between power and subdivision

Could replacing Hood's machinery add 60,000 shaft horsepower?

It could with new turbines and hull strengthening, although keeping roughly 33-34 knots could leave more room for protective subdivision.

Foxo's estimate proposes another 60,000 shaft horsepower from replacement machinery. Achieving that increase would require new turbines and strengthening the hull. Another option would retain similar power, or make a modest increase, while using the space released by modern machinery for additional subdivision. The preference here is approximately 33-34 knots with greater survivability. The estimate describes an engineering option rather than an adopted reconstruction plan.
