Messerschmitt Me 210, 310 and 410

One reason the Bf 110 had to fight on for so long was the failure of the Messerschmitt Me 210, the aircraft designed to replace it. After a brief service career this aircraft had to be withdrawn. A first attempt to salvage the project resulted in the Me 310, a proposed high altitude fighter/ bomber, but it was not until the appearance of the Me 410 in 1943 that this type entered service in any significant numbers.
