Extra U.S. destroyers in Royal Navy service

If the Royal Navy had forty-four U.S. destroyers plus perhaps another sixteen, how would they be used?

They would be used as destroyers, probably spread through the Grand Fleet, battlecruiser force, and Channel squadron duties.

The extra American-built ships would enter service as ordinary destroyers rather than create a new strategic role. They would likely be divided among the Grand Fleet, the battlecruiser force, and Channel duties. Additional escort numbers could be absorbed within existing Royal Navy organisation without changing the whole war plan.
