The HAL HF-24 Marut was an Indian jet fighter aircraft developed and manufactured by Hindustan Aeronautics Limited (HAL) during the 1960s and early 70s. The Marut was designed by the German aeronautical engineer Kurt Tank, with the Project Engineer being George William Benjamin. The aircraft was the first Indian-developed jet fighter and the first in Asia, outside the Soviet Union, to go beyond the test phase and into serial production and active service. On 17 June 1961, the type conducted its maiden flight; on 1 April 1967, the first production Marut was officially delivered to the IAF.
