How did Royal Navy hull design evolve between Nelson and the King George V class?
Short answerThe hulls reflect different design problems: Nelson had to deliver efficient 16-inch fighting power under a tight weight limit, while the King George V design's 14-inch armament changed the weight distribution available to the hull.
NotesThe answer cautions against reading hull evolution as a simple sequence of better shapes. Nelson and Rodney were optimized around the most efficient 16-inch-gun arrangement possible within their displacement constraint. Moving to 14-inch weapons changed the weight budget and allowed King George V's designers to pursue a different overall balance.
