Question

When did the US Navy replace the Royal Navy as the principal force policing the world's sea lanes?

Short answer

Around 1950 rather than immediately in 1945, because the United States needed time to acquire the overseas bases and infrastructure that Britain still operated.

Notes

A viewer suggests that the Royal Navy policed the seas from 1815 to 1922 and the US Navy from 1945 onward. The response places the practical handover around 1950: the American fleet was larger by 1946, but it did not yet possess the worldwide basing and support network required for the job. Britain continued much of the policing role while American forces moved into former British positions. American postwar support, including parts of the Marshall Plan, also helped keep British naval infrastructure functioning during that transition.
