Status Unrealised project

The Messerschmitt Me 509 was an all-metal fighter project underway in Germany during World War II.

Development[edit | edit source]

Not much information about this project has survived. It was based on the Me 309 but with the engine located behind a pressurized cockpit,[1] much in a similar manner as the US Bell P-39 Airacobra.

The engine was a Daimler-Benz DB 605B driving a three-blade propeller and armament was to consist of two 13 mm (.51 in) MG 131 machine guns and two 20 mm MG 151/20 cannons. The tricycle landing gear from the Me 309 was retained, which worked better on the 509 due to the lower weight on the nosewheel - the Me 309's front landing gear had collapsed during trials. The smaller nose would have improved visibility. The project was cancelled along with the Me 309,[2] but the Japanese made a similar aircraft, the Yokosuka R2Y Keiun, which suffered from engine overheating.
