If you want to hear about jugaar...
In the 1980s, the South Africans tried developing their own 4+ gen fighter.
It was supposed to be a single-engine fighter.
But they couldn't get the M53 or F100 engine, so what did they do?
They decided to go for a twin-engine design.
Why?
Because they could at least fit tuned-up ATAR 9K turbojet engines to it (until they develop or secure a 80-90 kN class turbofan). But it doesn't change the fact that their next-gen fighter was to use Mirage F-1 or Cheetah engines.
That is jugaar.
