Beside the different paint job and camera angle, they are identical (though only in appearance; not quality and ability). HAL Tejas is a blatant copy of the French Mirage with no regards to intellectual property rights. It took 40 years for india to copy a plane that took France less than 5 years to develop and build.
The Mirage III family grew out of French government studies began in 1952 that led in early 1953 to a specification for a lightweight, all-weather interceptor.
1st flight: 17 November 1956
