Overview
The first Messerschmitt Me 209 was a single-engine racing aircraft which was designed for and succeeded at breaking speed records. This Me 209 was a completely new aircraft whose designation was used by Messerschmitt as a propaganda tool. Although the aircraft was designed only to break speed records, it was hoped that its name would associate it with the Bf 109 already in combat service.
The designation Me 209 was given for propaganda purposes to cause confusion with the Messerschmitt Bf 109, the Luftwaffes primary fighter throughout World War II. It was later reused for the actual proposed successor to the Bf 109.
Design and development
The designation Me 209 was used for two separate projects during World War II. The first was a record-setting, single-engined race aircraft, for which little or no consideration was given to adaptation for combat. The second Me 209 was a proposal for a follow-up to the highly successful Messerschmitt Bf 109 which served as the Luftwaffe's primary fighter throughout World War II.
Designed in 1937, the Me 209 was a completely separate aircraft from the Bf 109, solely designed to break speed records. It shared only its Daimler-Benz DB 601 engine with the Bf 109, which in the Me 209 was equipped with steam cooling. Willy Messerschmitt designed the small aircraft with a cockpit placed far back along the fuselage just in front of its unique cross-shaped tail section. Unlike the Bf 109, the Me 209 featured a wide track, inwardly-retracting undercarriage mounted in the wing section.
