The Messerschmitt Me410, nicknamed the Hornisse ("Hornet"), was a German heavy fighter and Schnellbomber used by the Luftwaffe during World War II. It was developed from the Me210 and fitted with a more powerful Daimler-Benz DB 603A engine, which greatly improved its flight performance . A BK5 50-mm cannon was added to the Me410B-2/U4，which greatly enhanced the combat capabilities. Hence it was called“bomber-killer”.
