Triple turrets in the 1909 arms race

What were other navies doing with dreadnoughts in 1909, and would a British triple turret matter?

Several navies were already pursuing triple mounts, but an early British move could produce an especially large broadside advantage over Germany.

Britain would enter a busy international field if it adopted triple mounts. Italy and Russia were already working on triple-turret battleships, Austria was pursuing similar ideas, and Vickers had offered triples for Japanese projects while the United States and France developed their own new dreadnoughts. Germany is the most consequential comparison because its contemporary wing-turret ships could bring only eight guns to a broadside despite carrying six turrets. A British Orion with larger guns and a thirteen-gun broadside would therefore sharpen the competitive pressure on the Imperial German Navy, even though triple mounts were already under development elsewhere.
