Could a Fuso-class battleship reach 27 knots by removing one or both midships turrets?
Short answerYes, with a difficult early-1930s reconstruction that devoted the freed space to high-pressure boilers, machinery, and fuel.
NotesRemoving one or both of Fuso's midships turrets would free internal volume for machinery and fuel. A 27-knot target is technically possible if the conversion used the best high-pressure boilers available in the early 1930s. The reconstruction would be difficult, and the ship would surrender part of its main battery to gain speed. Modernisation depends on usable machinery space and contemporary boiler technology, not simply on reducing displacement.
