WW1 Paved the Way for the Battle of Britain.

Kurfurst- the Germans knew about the British radar, but it was so far inferior to the German's that they dismissed it. They failed to realise how the radar information was used as part of an integrated intelligence gathering network to give the RAF dispatchers an almost real-time picture of what was happening.
The British mistakenly overestimated the LW capabilities and geared production to match it- they believed the German propoganda!
