Improving a Canada-class battleship means choosing among upgrades that cannot all be had at once. The refit exchanges twelve 15-inch guns for nine 16.5-inch weapons, sacrificing three barrels for greater range. Stronger secondary armament, radar, and better accuracy add to the firepower gain. Armour is trimmed to control displacement, while the fourteen-month refit creates a readiness risk before the expected American challenge. The result illustrates the tradeoffs among firepower, sensors, protection, tonnage, and time out of service.
