The Heinkel Doppeldecker 43 was a prototype German fighter aircraft of the 1930s. A single-engined, single-seat biplane, the HD 43 was designed to meet a secret German Reichswehr requirement for a single-seat fighter. It had two-bay wooden wings with a steel-tube fuselage, and was powered by a 750 hp (600 kW) BMW VI engine. The single prototype flew in 1931.[1]
It was evaluated against the Arado Ar 65, with the Arado being selected and no production of the Heinkel followed.[1]
