The Heinkel HE 6 was a single-seat floatplane developed by the German aeronautical company Heinkel Flugzeugwerke in the late 1920s.

Development

In the 1920s many aviators attempted the venture to cross the Atlantic even if they lost their lives when on 21 May 1927, after a flight of 33 hours and 30 minutes, Charles Lindbergh made the venture from New York to Paris. The most difficult task on the contrary still remained to be done, since the winds on the Atlantic were mainly blowing from east to west. 11 months later Koehl von Hünefeld und Fitzmaurice performed the business on a Junkers W 33.

In 1927 the construction of this aircraft was presented as a private initiative by Ernst Heinkel but in reality behind it were the Reichsmarine and the Hamburg-America Line. The naval command had requested the Lorenz and Telefunken companies to develop radios for aircraft destined for the enterprise but the involvement of the military, as the development and construction of military aircraft was forbidden to the Germans according to the terms of the Treaty of Versailles.

The Hamburg-America Line ( HAPAG ) was one of the largest shipping companies in the world based in Hamburg. It had developed in the second half of the 1920s and was rather interested in aviation to the point of having established a special section "Luftfahrt" (aviation). HAPAG financed two projects:

While the G 24 remained the property of Junkers Flugzeug- und Motorenwerke AG, the HE 6 passed to HAPAG for around 120,000 marks (engine excluded). HAPAG also assumed other costs such as insurance, fuel, personnel, organization with 245,000 and 180,000 marks respectively for the G 24 and the HE 6.[1]
