F-21 is a F-16 block 70 with F-35 like cockpit and composite materials, triple missile launchers and Gallium nitride version of APG-83 and other EW systems. Comparing Su-75 which has not flown with a proven airframe is naive. It is a F-16 block 70 but with elements of F-35 Block 4 since india requires a 4.5 gen jet with modern avionics and cheaper price USA has pitched this. But again I would say getting something is better than nothing. If Rafale does not work out , su-57 does not work out F-21 will give us something. My ideal choice would have been F-15EX but again it is a heavy fighter in Su-30 category so we won’t have it . Eurofighter typhoon has multiple issues . Gripen e is another fighter I would be happy with if Rafale doesn’t win due to price
Its a wrong step.We already have rafale,just top it up.No need to have 10 different set of equipments.
And I would reiterate ,F-21 is a thing they are offering only for India and it is not under any service and is not expected to be.Just a lollipop for stupid Indian defence planners.
We area poor nation ,economy is barely going to tough 4 trillion with huge population.Why not act a bit smart by getting similar equipment in good numbers.Just like elections every 3 months ,we have these stupid new RFI and contracts every few years.
I am not fan of rafale ,in my opinion it's just obsolete vs j-20 based on stealth alone ,it would be seen first and shot at first.So ideally yes I agree with u 100 percent we should have gone with F-15 silent eagle just based on better stealth than rafale.But that ship has sailed ,we already have rafale and for the sake of making process easier and more integration we should get these only.
All the effort and time for stealth and other features should be spent on amca.
I have said many times already,the new gen war with extensive esm ,jamming ,sir defence won't be determined by air force especially against capable opponents( China ) so better strategy is to be able to build everything and fast. Only forces that can replace the lost equipment have any chance of winning the modern war.
