Development

Austrian engineer Ferdinand Brandner, who had worked in the Soviet Union, leading the development of the Kuznetsov NK-12 turboprop, the powerplant of the Tupolev Tu-95 bomber, moved to Egypt to lead a team to design an engine to power the Helwan HA-300 jet fighter that was simultaneously being designed by a team of Germans led by Willy Messerschmitt.

The new engine underwent bench testing in 1963, and was flight tested under the wing of an Antonov An-12, before being installed in a HAL HF-24 Marut for high speed testing, in which form it flew on 29 March 1967.[1] The E-300 was installed in the third HA-300 prototype (the first two were powered by Bristol Siddeley Orpheus engines), but attempts to fly it were unsuccessful. The programme of HA-300 was abandoned in May 1969.[2]
