first of all we should know what is the RCS of FGFA of PAKFA, if it is more than F-22 and J-20 then IAF should reject it outright,
and ask SUKHOI to deliver a more stealthier version for the 20 billion dollar indian tax payer money that is going to be funneled into it's bank accounts,
In the same way as ADA was asked to deliver TEJAS mk-2 version with better capability, IAF should ask SUKHOI to deliver a much more stealthier mk-2 version of FGFA,It is a commercial contract not a charity, so there is nothing wrong in it.
The IAF asked ADA to change the AMCA deisgn for a much more stealthier version , the same should be applied to FGFA as well.
it is useless to introduce a so called 5th gen stealth fighter that has more RCS than what chinese J-20 and J-31,
Because with improvement in all bands of ASEA radar tech, a beach ball sized RCS of FGFA won't be of much use to be called as true blue 5th gen fighter,
This point is often glossed over, we are not buying PAKFA to have a compromise of super agility and stealth,
if FGFA is going to have a bigger RCS than AMCA , then what will be india's premier fighter?
