How a 14-inch Dreadnought could accelerate gun escalation

What follows if HMS Dreadnought begins with twin 14-inch guns?

Later classes would need to escalate sooner, potentially moving the Orions toward 16-inch guns and forcing the Queen Elizabeth class toward triple 16-inch mounts or 17- to 18-inch weapons.

A Dreadnought starting with 14-inch guns would leave later British classes needing a larger step in armament. The Orion class, which historically moved to 13.5-inch guns, would need a different improvement, with 16-inch guns emerging as a possibility. That would put further pressure on the Queen Elizabeth class to carry larger guns or triple 16-inch turrets. These are proposed consequences of the counterfactual, with no single later calibre treated as inevitable.
