Messerschmitt Bf-110 G4 night fighter

The Messerschmitt Bf 110 G-4 was used primarily as the Luftwaffe's principal radar-equipped night fighter to defend the German Reich from Allied bombing raids during the later years of World War II, specifically from 1943 to 1945. It operated extensively over occupied Europe and Germany, targeting British Lancaster bombers and American aircraft.
