"Specs" isnt everything.seriously specs of mk1 sounds from 1980's era and even lower than Mig21
Its the "Technology".
Glass cockpit , Fly by Wire , Composite Structure , Pilot friendly controls, advanced avionics , Pulse dopler Radar(150kms Air-Air / 300kms Air to Sea), maneuverability and agility. Etc.
These technologies arent available in a 1980s aircraft.
I would say Tejas mk1 is a 90s Aircraft to be honest. We are some years behind ,yes, but the success of Tejas laid a strong foundation for the Indian Aerospace industry.
And Oh yes, the Price, its just under 30mil$ each. One of the cheapest in the world.
