In that case maybe consider something like above.
This platform is not flashy, its not glamorous, its not a superstar aircraft like an F-22, F-35, Eurofighter, Su-35 but its inexpensive, simple to operate, reliable, easily maintainable, and effective.
It appears to have a very capable electronic warfare suite and advanced avionics. Saab is open to technology transfer and will open a local production plant if selected.
The Gripen E is a bread and butter aircraft, a workhorse, the type that will do most of the fighting in an actual war.
And yes I've heard the argument against it, by choosing a completely new platform with which the IAF has no prior experience.
The Gripen E will make up the shortfall in aircraft numbers which the IAF is currently facing.
It appears to be a similar type of aircraft like the Tejas and is arguably what the Tejas can be or should be.
But it and other 4th gen aircraft like it will likely still be outmatched by a J-20.
Since F-35 is not an option, that vulnerability remains unaddressed.
Other fifth gen aircraft which can be considered include the Mitsubishi X-2 Shinshin, KF-21 Boramae or the Su-75 Checkmate.
But they all appear to be a long way away from entering active service.
