Sukhoi Su-57 flight testing and development

Agreed, on global scale - esp. in comparison to Europe - it is, however they are not built completely ingeniously and well, 222 since 2004 – and unfortunately I don’t know the annual breakdown (though I’d be happy to be corrected) – that’s just 10 aircraft a year over 22 years … compared to 400+ J-16s (alongside other Flanker variants) in China since 2014!

And their share of domestic production is also significantly lower!

But that’s taking us off topic.

Even new contract for 12 Su-30MKI ( I suppose the replacement for lost ones) ,means production throughout 2027 and 2028, so 6 aircraft per year only.

W/o the great Russian support in all domains, HAL will never be capable to 'produce' Su-57E/D and not only from the beginning but in the phase of assembling them like you mentioned earlier.From the Sukhoi 's book we found out what kind of difficulties KnAAZ had with some Al-Li Alloys. I think that complete composite made parts for the skin will be transfered to HAL from Russia for the each aircraft if they start to 'produce' them at all.

That's a solid, mainline level manufacturing output. Few countries have money to even afford more.

China specifically is one of two that can. It is just an unfair comparison; China is simply a several times larger economy.

It's like asking why Su-57 numbers per year are so low. Is 12...18 heavy fighters really low when measured against economy scale and VKS size?
It'll be low if notional Su-75 were to try to substitute several types in a sufficiently affordable package. But there's no su-75.
 
Is this correct?

At least two new upgraded Su-57s have been delivered to the VKS. The 101KS-U window, featuring a massive infrared sensor, is clearly visible. This component probably bears a different designation now.
