Hindustan HF-24 Marut
Development: After 1950 the Indian government decided to authorise development of an Indian combat aircraft, and the services of Dipl -1 ng Kurt Tank, the renowned Focke-Wulf designer, were secured to lead a new team formed by Hindustan Aircraft at Banglore. Detail design began in 1956, the objective being to create a multi-role aircraft potentially capable of reach­ing Mach 2 with minimal technical risk. The prototype, powered by two of the same engines already being produced for the Gnat, proved generally successful, and two of the 18 pre-production Maruts ("Wind Spirit")-were officially handed over (though as a token delivery) to the IAF in May 1964, the year the company reorganised and expanded into its present form as

Hindustan Aeronautics. By the end of 1 976 about 100 production Mk Is had been delivered, many of them being used (without loss) in the December 1971 war against Pakistan. The Mk IT has a second Martin-Baker seat in place of the rocket pack and has since 1974 also been produced in small numbers as a dual conversion and weapon trainer. In 1967 the German staff left and an Indian design team has since continued the 20-year search for a more powerful engine. HAL has tested afterburning engines and flew the Marut IBX with one Orpheus replaced by an Egyptian Brandner E-300. but the most likely solution will be the HSS-73 (Marut III) with two Turbo – Union RB.1 99 engines in a considerably improved airframe. Despite obvious handicaps HAL has already created a useful multi-role platform which could carry radar, cameras or other equipment and has reached a satis­factory state of operational development. The Mk III could continue the same basic design to the end of the century.
