Fighter ace Walter Nowotny taking a close look at one of the Höhenjäger test beds. The Fw 190 V32 ‘GH+KV’ was designed as a DB 603 S-1 powered high altitude fighter and was one of Tank’s many projects powered by the big 445-litre DB 603 engine-even though the official view favoured the Junkers 213. Note the four-bladed propeller and pressurized cockpit. This machine would later be re-built as a Ta 152 prototype.
