This led to development programmes which would produce the world’s first fully operational jet and rocket fighters. he turbojet wasinvented in Britain during the 1920s –but wherethe TBritish government hesitated to provide the financial support needed to develop it, the Nazi government had no qualms about taking agamble on this potentially revolutionary engine. Moneywas also made available in large quantities to pursue intensiveresearch on liquid-fuelled rocket motors and pulse jet engines forboth missiles and aircraft. It wasanage of unprecedented technological discovery and scientific progress right across Europe and the arms race that precipitated the slide into war only accelerated the rate of advancement. At the beginning of 1939, the Reichsluftministerium (RLM) issued the world’sfirst specification foraturbojet- propelled fighter aircraft and in the months leading up to the Second Wo rldWar the Germans flight-tested both the world’s first turbojet aircraft and the world’sfirst liquid-fuelled rocket-propelled aircraft. The German aeroengine industry was actively encouraged to invest in research on newturbojet and rocket motor designs ABOVE: Aradically different Me 262. This drawing shows amodel that was tested in the DVL’ swind tunnel in July 1942. Even at this stage Messerschmitt was making plans to improve the aircraft’s and companies including BMW,Bramo, aerodynamics.

At Junkers, Wagner begins construction of his ownturbojet engine. • Autumn 1938 German aero engine manufacturers Daimler-Benz, BMW,Brandenburgische Motorenwerke (Bramo) and Junkers are encouraged to look at turbojet development by the RLM. • Early 1939 Junkers’ Rückstoss-Turbinen-Strahltriebwerk (RTO) or ‘Reaction Turbojet Engine’ runs up to 6500rpm on atest stand. It is designed to reach 12,900rpm. • January2,1939 Alexander Lippisch and his team transfer from the DFS to Messerschmitt AG at Augsburg. TheyformAbteilung
