The Germans nevertheless persisted in their attempts to create newer Schnellbombers, as opposed to large bombers with heavy defensive armaments which were favored by the RAF and USAAF. Other aircraft recognized as Schnellbombers by the Luftwaffe were the Junkers Ju 88,[1] the first to be custom-designed for the role, three years before the start of the war, the Messerschmitt Me 410 Hornisse in 1943, and the jet-engined Arado Ar 234 Blitz (dubbed "the fastest bomber" – "Schnellstbomber").
