How heavy would a 28-knot battleship armed with twelve 18-inch guns be?
Short answerRoughly 50,000 to 60,000 tons, with Britain's 1910 shipyard-upgrade cycle expanding the capacity needed to build it.
NotesA ship combining twelve 18-inch guns with 28-knot speed is tentatively estimated at roughly 50,000 to 60,000 tons. That is an estimate for the scenario rather than a completed design. Shipbuilding infrastructure could expand in response to the programme, and Britain's historical 1910 yard upgrades later supported ships as large as Hood. Earlier growth in capital-ship requirements could redirect that investment cycle towards the proposed fleet. A direct comparison with Yamato also needs care because its Second World War requirements included protection against aircraft and extra subdivision.
