argue the HAL Marut, despite being unsatisfactory, was more successful than the Tejas. Atleast it got manufactured in decent numbers and experienced operational combat.
Building on the Marut experience, the Tejas program should've been better, not equal or worse. It seems like the argument from the Indian side is that they are repeating that huge step forward with no actual change in progression.
Marut, whatever was left of it, was clearly wasted before Tejas. Step too long, step too far.
Also, Tejas is on path for both, so it isn't fair to compare them just yet.
Both Marut and Tejas were partially crippled, but Tejas seems to get out of hell with mk.1a. Still largely on foreign components, but persistence itself is a merit.
So are engineers, which now oversaw full development cycle right to the viable product.
