Heinkel produced three different designs of the P.1078 for the OKL Emergency
Fighter competition in 1944. The Heinkel He P.1078A was a single-seat fighter
armed with two MK 108 30mm cannon in the nose. The shoulder-mounted gull
wing was swept back at 40 degrees, and was powered by one HeS 011 jet engine
located beneath the cockpit and exhausting under a central tailboom.
