Entwicklungsring Süd (EWR) was a German consortium formed in 1959 to build a Mach 2 Vertical Take-Off Interceptor for the Luftwaffe.[1]

History

The consortium was formed in 1959 by the German aircraft companies Bölkow, Heinkel and Messerschmitt to develop a Mach 2 VTOL interceptor for the German Air Force.[1] In 1964 Heinkel left the consortium and the following year it was formed as a company Entwicklungsring Süd GmbH.[1] A VJ 101C prototype aircraft was built and flown in 1963 although it crashed on its 132nd flight, on 14 September 1964, during a normal horizontal take-off. The accident was found to have been caused by a roll-rate gyro which had been installed with reversed polarity.[2] A modified second prototype flew in 1965 and it was planned to put an improved variant VJ 101D into production, but the development was stopped.[1]

EWR teamed with Boeing, Fairchild, Hiller and Republic Aviation for the Advanced Vertical Strike (AVS).[3][4][5]
