After the Battle of Britain, Bf 110 was used in the Mediterranean and the Soviet Union. Once Bomber Command increased its nocturnal raids over Germany, most Bf 110s were sent to new night fighter units. Equipped with radar it proved to be an effective interceptor beginning from mid 1941 and the Bf 110 began to take its toll on RAF bombers and was soon an aircraft to be feared but was limited by its speed, caused by draggy radar antennas, and short range.
