In March 1945, the Heinkel design team under the leadership of the Dipl.-Ing. Siegfried Günter, designed a high-altitude tailless interceptor named He P.1080, with a 15,100 hp. Sänger 900 ramjet in each wing root, and a maximum take-off weight of 3.325 kg. The P.1080 could fly for 90 minutes, with 1,100 kg of fuel, at an estimated maximum speed of 980 km/h. The take-off was carried out from a detachable trolley, take-off acceleration was provided by four Schmidding 109-533 solid-fuel rockets.
At the end of 1944 tests were carried out with several ramjet engines of the type called RL (Raketen-Lorin) in the BMW wind tunnel at Oberweisenfeld. They consisted of a cold rocket embedded into the air-intake of a Lorin ramjet, to induce the necessary airflow for operation while stationary. The rocket would be deactivated when ignition velocity was reached.
Research with RL ramjets was sponsored by the Junkers Company in order to increase the range of the Me 263 fighter by adapting two RL ramjets with 84-cm diameter under the wing roots.
