The Arado Ar 198 was a prototype reconnaissance aircraft developed by Arado Flugzeugwerke, with backing from the Luftwaffe, who initially preferred it over the Blohm & Voss BV 141 and the Focke-Wulf Fw 189. However, when flight tests were carried out the aircraft performed poorly, and did not impress the Luftwaffe. One aircraft was completed in 1938.
