Heinkel P.1079

The Heinkel P.1079 was a late‑war German experimental jet designed by the Heinkel company as part of the Luftwaffe’s effort to field a high‑performance, rocket‑assisted interceptor. Initiated in early 1945, the project sought to combine a compact Heinkel HeS 011 turbojet with a small, liquid‑propellant rocket motor to achieve climb rates far beyond conventional fighters. The airframe featured a sleek, low‑drag, swept‑wing layout with a distinctive T‑tail and a compact, press‑urged cockpit situated far forward to improve pilot visibility during steep ascent. Structural emphasis was placed on lightweight alloy construction and integral fuel tanks that also served as rocket propellant reservoirs. Although wind‑tunnel tests and limited static firings indicated promising thrust‑to‑weight ratios and a projected maximum speed exceeding 1,000 km/h, the P.1079 never progressed beyond prototype mock‑ups due to Germany’s collapsing industrial base and the imminent end of the war. Its significance lies in demonstrating the feasibility of mixed‑propulsion concepts that influenced post‑war designs such as the Soviet MiG‑9 and early Western research into combined‑cycle aircraft, marking an important transitional step toward modern high‑speed jet propulsion.
