Egyptian General Aero Organisation E-300
The Austrian engineer, Ferdinand Brandner, who had previously worked as a prisoner of the Soviet Union on the development of the Kuznetsov NK-12 turboprop that was 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 turbojet 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. The E-300 was installed in the third prototype HA-300 (the first two powered by Bristol Siddeley Orpheus engines), it flew at least one time and successfully, but the programme of HA-300 being abandoned in May 1969.
