A K3 counterfactual: treaty limits and rival responses

Notes

The scenario begins with the likelihood that Japan would answer a British 18-inch-gun ship with another large design of its own. It then imagines the Royal Navy choosing K3 early, cancelling the Admiral class sooner, and completing two K3s before an early treaty settlement. The two unfinished sisters might be cancelled or converted in a manner analogous to Lexington and Saratoga. The completed ships would enter a force that still included Renown, Repulse, and older battleships, creating difficult retention and modernization choices. These questions expose how one exceptional class could reshape several navies' procurement decisions without claiming a definite alternate timeline.
