What installed power would make sense for a battleship newly built in 2024?
Short answerPreferably nuclear power; otherwise a large gas-turbine plant broadly comparable to that of the Queen Elizabeth-class carriers.
NotesInstalled power must move a very large modern combatant rather than recreate a historical machinery plant. Nuclear propulsion is the preferred solution. If political or technical choices ruled that out, a large gas-turbine arrangement comparable in scale to the Queen Elizabeth-class aircraft carriers would provide the conventional alternative. That comparison gives a modern reference point for the machinery volume and output such a ship would demand.
