Were there fundamentally different ideas for refitting the Queen Elizabeth-class battleships?
Short answerNot primarily; the major difference was budget, with Warspite receiving the premium upgrade and the other ships receiving cheaper reconstructions.
NotesCompeting reconstruction philosophies were not the main dividing line. The more important distinction was how much money the Admiralty was prepared to spend on each ship. Warspite received the premium treatment. Her sisters generally received less costly packages rather than entirely unrelated modernization concepts.
