Not sure how true this is considering american history
Sanctions are the danger, not the strings.
Difference is that we gain technical know how and know why and production practice versus simply importing from unreliable partners like America.
We are not gonna get either know-how or know-why. Not even Rafale ToT comes with that. This is only for AMCA's engine.
For 6th gen, it's just foreground IP. You make the radar, it's yours. We make the radar, it's ours. Everything that led to the design and production of the radar belongs to the creator, not the partner, that's background IP. The only thing shared is the foreground IP based on financial share, there's no ToT. So we either replace the core avionics or import the core avionics. But doing the former is time consuming and defeats the purpose of the JV.
Manufacturing with ToT is essentially copying a blueprint, you only learn how to manufacture something. There's no R&D understanding involved. The idea behind production ToT is purely to support the IAF. It has zero influence in R&D programs.
Even with Su-57 production, we will only see a normal localization with zero impact on R&D, the same as MKI. Even the FGFA JV was just a more expensive indigenization program, where we pay and the Russians develop.
So whether it's SCAF, GCAP, or F-47, a large order only means local production for sustainability. But if we go for an F-47I with Israel, we will be able to upgrade an Indian/Israeli EW suite on our own while being able to add our own weapons wherever radar integration is not necessary. And an American jet will be globally sustainable. The F-35I is more sustainable than the F-35A too, it's independent from LM's logistics ecosystem. The Americans have offered the Saudis the same deal.
SCAF JV will take until 2045 to deliver full capability, Trappier hinted at 2050. GCAP will take until 2040. F-47 will take until 2035. It's obvious which one will save time.
