"Bf110C-4s were virtually immune throughout the Battle of Britain, with RAF tacticians acknowledging the fact that it out-performed the Hurricane Mk I in all regimes, and that it could out-climb the Spitfire Mk I; the dive-and-climb tactics of the Bf110s were effective, and the armament had to be watched with care."
Casualties of Bf110s in the Battle of Britain were high due the tactics Luftwaffe used then. Escort missions with throttled back, Bf110s were sitting ducks to Hurris and Spits.
