Focke Wulf Fw 190
Design & Development: Origin
Between 1934 and 1935 the German Ministry of Aviation (RLM) ran a contest to produce a modern fighter for the rearming Luftwaffe. Kurt Tank entered the parasol-winged Fw 159 into the contest, against the Arado Ar 80, Heinkel He 112 and Messerschmitt Bf 109. The Fw 159 was hopelessly outclassed, and was soon eliminated from the competition along with the Ar 80. The He 112 and Bf 109 were generally similar in design but the 109's lightweight construction gave it a performance edge the 112 was never able to match. On 12 March 1936 the 109 was declared the winner. Even before the 109 had entered squadron service, in autumn 1937 the RLM sent out a new tender asking various designers for a new fighter to fight alongside the Bf 109, as Walter Günther had done with his firm's follow-on to the unsuccessful He 100 and He 112. Although the Bf 109 was an extremely competitive fighter, the Ministry was worried that future foreign designs might outclass it, and wanted to have new aircraft under development to meet these possible challenges. Kurt Tank responded with a number of designs, most based around a liquid-cooled inline engine. However, it was not until a design was presented using the air-cooled, 14-cylinder BMW 139 radial engine that the Ministry of Aviation's interest was aroused. As this design used a radial engine, it would not compete with the inline-powered Bf 109 for engines, when there were already too few Daimler-Benz DB 601s to go around. This was not the case for competing designs like the Heinkel He 100 or twin-engined Focke-Wulf Fw 187, where production would compete with the 109 and Messerschmitt Bf 110 for engine supplies. After the war, Tank denied a rumour that he had to "fight a battle" with the Ministry to convince them of the radial engine's merits.
