What's wrong with tedbf , according to you , weapons bay ? Conformal sensor ,or anything else .
Well our indigenous engine won't be a drop fit when they arrive , we will require minor redesign , we can incorporate desired specs then , it can have internal bay ,but that will limit belly hardpoint , but if navy want that , don't you think it would easy to incorporate it when we already have experience of amca with us .
Stealth coating csn be applied , avionics will be a lot like amca , frontal stealth is there , in naval condition , awacs are generally not present so frontal stealth will be enough , high lift generation is present , if all this don't satisfy you ,then check out info regarding future aircraft for carrier operation bu us navy , they are asking for something like 4.5 th gen aircraft , either they are fools or their are some drawback of stealth , due to which we require a 4.5 gen aircraft .
