Here’s a 3 view including the two seat version.

SOC:

The Sh-90 was the program for the successor to the Su-25, around the same time as the I-90 (later: MFI) fighter program.

The T-12 is one design from this. Possibly that propellor driven Su-25 kitbash monstrosity was another design?

“237” is a later version of the “Su-37” design, undertaken by Sukhoi Stormovik. However, for now they are concentrating on Su-25 upgrades and derivatives, and this is never going to become a real plane.

It is said that there is no love lost between Babak and his attack aircraft team and Simonov’s fighter team. Simonov keeps stealing whatever designations Babak uses (e.g. Su-37, Su-34).

Definitely not a “winner” in my book 🙂

This is a generic “bomber” concept from the “stealth institute”.

One T-60 artists impression:

Yefim Gordon is certain its the MFI concept.

Heres that possible Kh-101:

The tell-tale sign of a stealthy design is its use of planform alignment.

The Yakovlev MFI clearly uses this.

In fact, I think it was a fine design hampered by the fact that they chose 1 engine, which was distinctly out of favour.
