Project V had the air inlets still positioned on either side of the nose, just below the cockpit.
The estimated horizontal speed was not satisfactory and in the next development, Project VII, the jet intakes were situated in the wing roots. Further improvements over Project VI were a narrower fuselage and a changed pilot's canopy. In order to improve the rate of climb, a Walter HWK 109-509hypergolic liquid-propellant rocket was built-in to give supplementary thrust. A complete mock-up was built and all construction and assembly plans were finished, but the aircraft was not accepted by the Reich Air Ministry (Reichsluftfahrtministerium, RLM).
