The Me 210 was designed to be the replacement for the Messerschmitt Bf 110. Because of design problems production was cancelled after 261 produced aircraft, so that production of the Messerschmitt Bf 110 was restarted. 148 of the already built aircraft got an enlarged fuselage and were equipped with new DB 605 engines, with that the problems could be fixed. All in all 325 Me 210 fighters were produced until March 1943. In Hungary, production was started at the beginning of 1943, so that 377 aircraft were built until the end of World War II. All in all 702 Me 210 were built. In the year 1943 the Me 210 was equipped with better DB 603 engines and entered service with its new name Messerschmitt Me 410.
