The BF110s were the most used German heavy warplanes during World War II. Development of the Me 210, which was suppose to replace the BF 110 began before the war, but with severe issues in development the BF 110 remained Germany's primary heavy fighter throughout the war.
Predecessor: Messerschmitt Bf 110B
Sucessor: Messerschmitt Bf 109
The Messerschmitt Bf 110, often (erroneously) called Me 110, was a twin-engine heavy fighter in the service of the Luftwaffe during World War II. Hermann Göring was a proponent of the Bf 110, and nicknamed it his Eisenseiten ("Ironsides"). Development work on an improved type to replace the Bf 110, the Messerschmitt Me 210 began before the war started, but its teething troubles resulted in the Bf 110 soldiering on until the end of the war in various roles, alongside its replacements, the Me 210 and the Me 410.
