The American response to a twelve-gun Queen Elizabeth

How would the United States respond to a Queen Elizabeth class with twelve 15-inch guns and 28-knot speed?

It would likely retain four triple turrets, accelerate the shift to twelve 16-inch guns, and reconsider the low speed of the standard battleship programme.

The likely response follows actual American design chronology from Pennsylvania through New Mexico and Tennessee. The United States already favored four triple turrets, so the British change would reinforce that pattern. The more important departure is speed. A 28-knot British battleship would pressure American planners to reconsider the 21-knot standard. The move to twelve 16-inch guns would probably arrive sooner as well.
