Despite being an Indian I have only criticism for Tejas plane.
I don't understand what Indians blabber about when they say that Tejas plane is indigenous.
Let us take the promise of indigenous development. In 1986 an agreement was quietly signed with the United States that permitted DRDO to work with four US Air force laboratories. The to-be-indigenously-developed engine for the LCA -- Kaveri -- was forgotten and the US made General Electric F-404 engine was substituted. Radar was sourced from Erricson Ferranti, carbon-fibre composite panels for wings from Alenia and fly-by-wire controls from Lockheed Martin. Design help was sought from British Aerospace, Avion Marcel Dassault and Deutsche Aerospace. Wind tunnel testing was done in the US, Russia and France. As for armaments -- missiles, guns, rockets and bombs -- every last item was to be imported.
