Couldn't resist so I got myself over to the above Wiki pg.
According to this entry, the Yaghout is in development and expected (by) 2025.
An Advanced 4++ generation heavy Interceptor, it is intended to be produced in two versions; A twin-seat model for the primary Air Force and a single-seat version for IRGC's Aerospace Force.
I found the flowchart of Iranian engine developments to also be telling in this regard.
According to
the final engine in this line of developments will be a Saturn AL-31(F), in 2026.
This at least make sense of reports that Iran is developing a heavy hunter and a heavy engine.
I looked for a single AL-31 powered a/c and came upon the Sukhoi S-54 et al for instance.
A bit on the short side but I think I ran over similar concepts as well.
