Royal Navy versus US Navy in 1946

Could the Royal Navy defeat the US Navy in 1946?

A fleet-on-fleet contest would be close in several categories, but a global war creates different geographic dilemmas and ultimately favors American industrial capacity.

The United States holds an important carrier advantage, while Britain retains strength across other categories and is already positioned in the Atlantic, Mediterranean, and Indian Ocean. The British Pacific Fleet would initially withdraw, but any American shift toward the Atlantic opens Pacific space; over time, American industrial output is the deciding advantage.
