Not entirely correct that the Stuka was ‘withdrawn from the battle due to vulnerability and unsustainable losses.’ There is, in fact, no evidence that this was the case. Rather, they were ‘withdrawn’ for operational reasons more than anything else – despite what almost every book says on the subject. And by mid to late August the Luftwaffe was preparing to change the direction of its attacks away from airfields. More importantly, the Stuka units were being moved and concentrated up into the Pas de Calais for employment in Operation [I][I]Sealion. Thus, the drawn down in Stuka usage was more to with strategy and tactics than it was to do with losses.

I covered this in some detail in my book ‘Stuka Attack!’

As a point of interest, the RAF claimed 172 Stukas destroyed over Britain in 1940, with 63 probable, 16 shared and 56 damaged.

In total, to all causes, the Luftwaffe lost 101 Stukas up until the end of 1940 in the campaign against Britain. Damaged, to all causes: 84.

From memory, there were about 52 lost (to all causes) up until 18 August.

Sorry for the thread creep! Maybe somebody wants to start a Stuka thread?!
