Which main battery would you choose to upgrade the King George V class, and why?
Short answerA modern 15-inch/45, because it would improve the new ships while also providing a practical modernization path for every existing Royal Navy 15-inch-gunned capital ship.
NotesA new 15-inch/45 is the preferred alternative to the King George V class's 14-inch gun. Developing it would also create a way to modernise the Royal Navy's existing 15-inch-gunned ships. The proposed gun is described as lighter than the older 15-inch/42, which would make replacement attractive. The Queen Elizabeth class and the rest of the 15-inch fleet could therefore benefit from the same development.
