Heinkel P.1079 — The Twin-Engine Jet Fighter of the Last Hour

Heinkel P.1079 — The Twin-Engine Jet Fighter of the Last Hour

The Final Chapter of Heinkel's Wartime Fighter Programme

The Heinkel P.1079 represents the last major fighter design concept to emerge from Ernst Heinkel Flugzeugwerke before the end of World War II. Developed in parallel with the P.1078 as part of Germany's frantic late-war effort to field a new generation of jet interceptors, the P.1079 explored a different approach to the same problem — a twin-engine configuration that promised greater performance and redundancy, at the cost of increased complexity and weight. Like its stablemate, it never flew.

Context: Germany's Last Fighter Designs

By early 1945, the Luftwaffe's situation was catastrophic. Allied forces were closing in from east and west, fuel was critically scarce, and the industrial base that had once produced thousands of aircraft per month was in ruins. Yet German aviation engineers continued to work with extraordinary dedication, producing design studies of remarkable sophistication even as the war entered its final weeks.

The P.1079 was one of several twin-engine jet fighter concepts studied by Heinkel in this period, alongside competing designs from Focke-Wulf, Messerschmitt, and Blohm & Voss. Each manufacturer was exploring different solutions to the fundamental challenge of combining high speed, adequate range, and sufficient armament in a single-seat jet fighter that could be produced with available resources.

Design Configuration

The P.1079 was designed around two jet engines — most likely the Heinkel-Hirth HeS 011 or Junkers Jumo 004 turbojets, depending on the variant studied — arranged to minimise asymmetric thrust in the event of an engine failure. Several layout configurations were explored by Heinkel's design team:

  • Twin engines side-by-side in the fuselage, with a bifurcated intake and twin exhausts — offering a compact, low-drag profile
  • Engines in tandem (one forward, one aft) within the fuselage — minimising frontal area but complicating the intake and exhaust arrangement
  • Podded engines under a swept wing — anticipating the configuration that would become standard on post-war jet airliners and fighters

The wing design drew on the swept-wing research already incorporated in the P.1078, with a moderate to high sweep angle intended to delay the onset of compressibility effects at high speed. A conventional tail arrangement — in contrast to the tailless P.1078 — was retained to simplify control system design.

Proposed armament followed the standard late-war Luftwaffe specification: two to four 30 mm MK 108 cannon, concentrated in the nose for maximum hitting power against Allied bombers.

Technical Specifications (Projected — Representative Variant)

  • Engines: 2 × Heinkel-Hirth HeS 011 turbojets — 12.75 kN (2,866 lbf) each
  • Wingspan: ~10.0 m (32 ft 10 in) estimated
  • Length: ~11.0 m (36 ft 1 in) estimated
  • Maximum Speed: ~950 km/h (590 mph) estimated
  • Service Ceiling: ~14,000 m (45,930 ft) estimated
  • Armament (proposed): 2–4 × 30 mm MK 108 cannon
  • Crew: 1
  • Configuration: Twin-engine swept-wing jet fighter
  • Status: Design study — never built, never flew

Why It Was Never Built

The P.1079, like virtually every advanced German aviation project of early 1945, was overtaken by events. Germany's unconditional surrender on 8 May 1945 ended all active development programmes. The partially completed design studies were captured by Allied intelligence teams — British, American, and Soviet — who systematically documented and analysed the extraordinary body of aeronautical research that German engineers had produced under wartime conditions.

Much of this captured knowledge directly influenced post-war jet aircraft development in the United States, the United Kingdom, and the Soviet Union. In this indirect sense, the P.1079 and its contemporaries did shape the future of aviation — even though they never left the drawing board.

Legacy

The Heinkel P.1079 closes the chapter on one of the most remarkable periods in aviation history — the extraordinary flowering of German jet aircraft design in the final years of World War II. From the pioneering He 178 of 1939 to the advanced paper projects of 1945, Heinkel's engineers traversed in six years a technological distance that would have seemed impossible at the outset.

The P.1079 stands as the final expression of that journey — a design that, had history unfolded differently, might have defined the first generation of post-war jet fighters. Instead, it remains a fascinating footnote: a window into what might have been, and a testament to the enduring human drive to push the boundaries of what is possible, even in the darkest of times.
