In 1944 Heinkel produced different designs of the project using either two Heinkel HeS 011 or two BMW 003 axial-flow turbojets. One of the turbojets was placed on top of the fuselage and the other in a ventral position. The engine below the fuselage was placed asymmetrically in order to provide space for the retractable front undercarriage wheel. The designs of this aircraft would be used by Heinkel to develop the He 162Volksjäger, which used only one turbojet engine, towards the end of 1944.
Variants
Heinkel produced twenty variants of the project between July 6 and October 3, 1944. All variants would have been armed with two 30 mmMK 108 cannons.
