We are adding incremental updates to MKI to keep it updated in light of the new threats faced.Super Sukhoi is 15 years away from being FULLY realised.
Both GOI & Russia are well aware of these bottlenecks. That is why a roadmap is being charted for acquisition of Su-57. PAF's J-35s won't cause too much trouble to IAF but PLAAF's J-36 & J-50 along with updated J-20As with WS-15s and GaN radars are a serious problem for us. That's why Su-57 with Indian avionics is being considered to deal with all above threats and give a breathing space to IAF up until 2040(when AMCA becomes fully combat ready).We don't know how effective the Su-57 is . We're only going by what we read & it really boils down to what we choose to believe on it given opinions in the MSM & SM on it is from end to end of the spectrum.
Secondly there's the issue of the war in Ukraine. The contracted S-400s of which 2 regiments were pending & which were finally supposed be delivered next year has now seen another revision in delivering time lines. We're getting one next year & the last regiment in 2027.
Not many reports coming out on Russia's own production status of the Su-57 for the past year or two. Add to that we've no news on the testing & more importantly the certification of the AL-51 on their latest model M of the Su-57.
There are too many gaps which need to be filled for is to get a couple of squadrons from the Russians & as of now I've only touched upon the problems on the Russian side. Our own MoD is not quite known to be agile in closing such deals.
Add technical & commercial negotiations to the mix. It's a bridge too late , too far IMHO.
PS: Did you read the acknowledgement of Dassault Chief Eric Trappier(posted by @Herciv) when he said that Rafale isn't essentially better than the Russian fighters? This was after they got some feedback from IAF about our Ops. What does it mean? Simply everything Vstol said about MKI & Rafale was correct. If MKI is so combat effective then Su-57 with our avionics is simply going to be a game-changer just like MKI & BrahMos, two of other Indo-Russian JVs/Collaborations are.
