Design debate and displacement margins behind battleships

Professional discussion of all-big-gun layouts, protective decks, junior constructors, and a four-percent displacement margin reveals how early battleship design managed uncertainty.

Notes

The published discussion preserves alternatives that did not become the final ship, including a twelve-gun all-12-inch proposal and debate over protective-deck geometry. One contributor notes that assistant constructors could carry responsibilities far beyond their formal rank; he had been thirty-eight during the King Edward VII design work. Weight estimates were serious enough for the Board of Admiralty to require an unassigned margin equal to four percent of displacement. Battleship design advanced through contested choices, institutional responsibility, and explicit allowance for construction uncertainty.
