The lack of sustained and concentrated attacks on radar left it free to help direct the deployment of RAF units at opportune moments. Its continued warnings of incoming raids were a crucial benefit to Fighter Command. The "Luftwaffe" also had poor intelligence on the type of RAF airfields. It made repeated errors, often misidentifying airfields as Fighter Command bases, which turned out to belong to RAF Coastal Command and RAF Bomber Command. On "Adlertag", most of the targets on the "Luftwaffe"s list—if destroyed—would not have impaired Fighter Command in the slightest.
