Each side receives the equivalent of a light cruiser's battery of six-inch guns because their range suits the expected fighting distances. Weight pressure forces a choice between an adequate 14-inch belt and the preferred 18 inches. The fifteen 16.5-inch guns remain the defining feature; without quad turrets, five triples provide the required volume. The game's lack of aircraft removes one real-world design pressure, although torpedo boats and submarines still justify sonar and lighter defences. The completed Thunder becomes the planned next generation after the battleships already under construction enter service.

The Thunder design is completed by balancing six-inch secondaries, belt armor, range, and defenses against small craft around its fifteen-gun main battery.
