Although reasonably fast (Bf 110C about 340 mph ) and possessing a respectable combat radius as well as carrying a heavy armament of two 20 mm MG FF/M cannon and four 7.92 mm MG 17s concentrated in the forward fuselage, along with a single 7.92 mm MG 15 mounted for rear defence in the rear cockpit, the 110 was only slightly more manoeuvrable than the bombers they were meant to escort.
