What additional prewar modification would most improve the Queen Elizabeth-class battleships?
Short answerModernise every ship along Warspite lines and replace the machinery to seek roughly 28 knots.
NotesThe answer prioritises machinery rather than a single additional weapon. Each Queen Elizabeth-class battleship would receive a broad reconstruction modelled on Warspite’s modernisation. New engines would aim to raise the class toward twenty-eight knots, improving its ability to operate with faster modern fleets. Achieving that across all five ships would require time and money, but the result would preserve a coherent group of useful capital ships rather than a mixture of heavily and lightly modernised sisters.
