Tillman battleships versus fleet production

If the Tillman battleships were built, what would the British response look like and what would battleships look like twenty years later?

Britain would likely answer with large but more numerous 18-inch-gun ships rather than a single enormous one-off, because industrial capacity favors classes over isolated monsters.

The Tillman idea separates spectacular displacement from sustainable fleet building. A plausible British response uses G3-style thinking, more 18-inch turrets, and multiple well-armed ships rather than one colossal hull. Answering a giant battleship therefore becomes an industrial choice about how many ships a navy can build, maintain, and bring to sea.
