How much did the Royal Navy value the 8-inch cruiser gun?
Short answerIt valued the gun relatively little and adopted it chiefly because treaty limits made 8 inches the relevant cruiser calibre.
NotesThe Royal Navy did not place great value on the 8-inch gun itself. British designers regarded it as insufficiently powerful for the larger cruiser capability they wanted. Treaty definitions nevertheless made the calibre the practical choice for the permitted class. Arms-control rules created a design compromise that the service would not otherwise select.
