rarest of the rare picture of Hindustan Aeronautics loaned HF-24 Marut fighter aircraft to Egyptian HA-300 fighter jet program to develop a new engine with German assistance which could have become first supersonic aircraft coming out of an Arab Country.
A modified HAL developed HF-24 Marut Mk.1 BX was loaned to Egypt to be used as a test bed to carry out engine trails for German-Egyptian developed E-300 turbojet which was capable of Mach 2 speed.
HF-24 which was powered by British developed Bristol Siddeley Orpheus Mk 703 turbojet barely was capable of reaching Mach 1 due to the lack of suitably powered engine for a Mach 2 capable air frame of HF-24. HF-24 attended Mach 1 speed only at Sea levels or at dive maneuvers.
After making repeated failed attempts to purchase suitable high powered engine from Western Powers like Britain and US for HF-24 ending with disappointments, India when invited to be part of Egypt’s attempt to develop a Mach 2 class fighter jet HA-300, along with E-300 turbojet for the program, willingly accepted Egyptian offer and also provided modified HF-24 fighter jet to be used as test-bed aircraft for E-300 program.
Mk.1 BX was equipped with one Orpheus Mk 703 turbojet and one German-Egyptian developed E-300 turbojet and this unique aircraft successfully flew around 140 test flights with Indian Air force Test Pilots who were deputed in Egypt to support test flight of HA-300 fighter jet and also to carried out engine trials of E-300 turbojet on request of Egyptian air force and government.
HA-300 programme was later canceled by Egypt in 1969, many Egyptian associated with the project believed that Soviet pressured Nasser to stop the program to prevent the HA-300 to pose as a challenge against the Soviet-developed Mig-21 and instead offered cheaper Migs to recover aircraft attrition lost in 6 day war with Israel.
The success of HA-300 program along with E-300 turbojet would have prevented the early demise of HF-24 Marut which never realized its full potential due to the insufficient power plant and had to be retired by early 80’s due crash of HF-73 Prototype which killed its test pilot and later Anglo-French made Jaguar aircrafts found orders from Indian Air force .
Mk.1 BX aircraft after the cancellation of the HA-300 project was given away as a gift and never made back to India.
