American and British obstacles to wartime ship production

What were the main obstacles to maximizing ship production during the Second World War?

American expansion first required more shipyards, while Britain faced coordination problems and changing priorities, with imported equipment adding delivery and installation delays.

The United States first needed to build the shipyards required for expansion. Britain's difficulty was managing work through existing yards while higher authorities changed the types of ships to prioritize. Fire-control equipment added another problem when British projects turned to American systems in expectation of greater production volume. Those systems had to cross the Atlantic and then be installed. Differences between British and American electrical systems could complicate installation and create further delays.
