List of Soviet/Russian 4th generation fighter projects?

[BESTUZHEV]

Hi everyone,
Of Soviet/Russian fighters of the 4th generation (that's the fourth, not the fifth and NOT a 4++ and 4+, I ask not to consider aircraft such as the MFIs, the MiG 35, PAK FA, etc) I know only MiG-29, yak 141/45/47/43 and su-27 (and all its modifications su-30 and su27KUB), but I'm sure there were other projects, in the end, unbuilt. I will be happy if one of you will write a list with the names of these projects (just names, without details will be enough). Perhaps one day this list will be useful not only to me
Mini-appeal to administrators: Yes, before making this post, I searched for the information I need on the forum and also in the internet, and eventually found nothing. If I did not search well, then before you block this post, please give me a link to the information I need,
Thank you
P.S. sorry for the Google translation
P.P.S. maybe Hesham can help me because he has a lot of similar information

[hesham]

For Sukhoi,

Very few of these are 4th gen.

I think hesham means Izdeliyie which is best translated as Product or Article not Aircraft.

Izdeliyie 721/723 are 5th gen MiG designs from PAK FA era.

Izdeliyie 33 was 4th gen, Izdeliye 41 never heard of, Izdeliyie 4.12 is LFI, Izdeliyie 5.12 is MFI , both being 5th gen, SFI never heard of.
