Dropping 1945 American gunmaking into the dreadnought era

Giving the 1910 United States a complete 1945 heavy-gun industry rapidly escalates battleship and cruiser armament on both sides of the Atlantic.

Question

What if the United States' complete 1945 manufacturing base for guns above 30 mm appeared in 1910?

Short answer

American battleships would adopt 16-inch guns much earlier, and Britain would counter with larger capital-ship and cruiser weapons, sharply accelerating the naval arms race.

Notes

The premise transfers the complete 1945 American manufacturing base for guns above 30 mm to 1910, including the supporting manufacturing knowledge. Nevada and later Standard-type battleships are expected to adopt 16-inch/50 weapons much earlier. The rapid-fire 8-inch guns associated with Des Moines also enter the cruiser discussion. A British response could include 9.2-inch cruiser guns and 16.5-inch capital-ship weapons. A twelve-gun Queen Elizabeth alternative is mentioned on the basis of design notes suggesting the option; a complete design or set of drawings is not claimed.
