I don’t think they used a lot of Sutkas in the Battle over Britain. AFAIR the main bomber used by the germans was the He111, but even that can be considered being a “light” and underarmed bomber compared to the flying fortresses and the like the allied used in the germans sky later in the war.
As many as 500 Stukas a day were sent in the Battle of Britain (mainly during Phase I: 12 August - 18 August 1940), by August 17, more than 30% of the Ju-87 Stukas sent against England did not return. The He111 was indeed the majority bomber used by the Germans since they lacked any better ones. Due to the limited range of the Me-109, the the Bf-110 Zerörsters were mainly used as escorts, but not only could not defend the bombers, they needed fighter escorts themselves.
There was one 4 engine “bomber”, very long range, but that was used only for recon, supporting the subs in finding their prey: the FW 200 Condor
Correct, though the Condor was more of a commerical transport. Good at first due to its range and bomb holding, but poorly defended against air attack. :-?
