28 Invasion barges in Channel ports
Operation Seelöwe Invasion barges in Channel ports July 1940

29 Operation Sealion Germans began planning for invasion in November 1939
Initial criteria for success: * The Royal Navy had to be eliminated. * The Royal Air Force (RAF) air strength had to be eliminated. * British coastal defenses had to be destroyed. * British submarine action against landing forces had to be prevented.

30 The air battle must be won if the war is to be won.
First Law of Modern War The air battle must be won if the war is to be won. General of the Army Omar Bradley November 1951

31 USAF Doctrine (modern) Priorities for tactical (theater) airpower:
1. Air Superiority 2. Interdiction 3. Close Air Support

32 Operation Sealion Hitler’s conditions for Sealion:
Defeat of the Royal Navy in the invasion area required control of the air Hitler’s conditions for Sealion: The RAF is to be "beaten down in its morale and in fact, that it can no longer display any appreciable aggressive force in opposition to the German crossing". Warning Order for Seelöwe, 16 July 1940

33 Operation Sea Lion German Plan Take control of the air
1940 German Plan Take control of the air  Defeat the RAF Isolate the invasion area  Neutralize Royal Navy, destroy communications & defenses Invade England  Land Panzers to employ Blitzkrieg tactics Source: Royal Air Force
