&gt; If we turn our attention to point 3 [What is going to prevent the RN from interfering?] for a while, the standard response is to say that the Luftwaffe could sink the RN ships. However, the Luftwaffe of the period had a pathetic record against warships. 39 RN destroyers took part in the Dunkirk evacuation. This operation required manoeuvring in a small harbour, with periods stationary while embarking troops. The Luftwaffe had command of the air for long periods. In these ideal conditions, the Luftwaffe managed to put out of commission a grand total of 4 destroyers. 4 out of 39 does not bode well for the Luftwaffe&#x27;s chances.<p>Addressed pretty solidly I think, everyone except the German air force did well against navies. Air superiority doesn&#x27;t matter if they can&#x27;t destroy the targets on the ground&#x2F;sea.
