Current project

MiG-xx series names were allocated sequentially (odd numbers only) by the Soviet Air Force. So, as the MiG-31 was the last model made, the next machine to be built would have been (and still would be, in the Russian Air Force) the MiG-33. There were no other projects further advanced to fill the -33 and -35 slots to make the 1.42 into MiG-37.

Mikoyan touted the MiG-29M (official name) as MiG-33 at one point, but it wasn't official- just a way of emphasising it was a new machine.

Likewise, Sukhoi called the Su-27M the Su-35, and then Su-37, and the Su-27IB has been called Su-32 and Su-34. The Su-25TM has also been Su-34 and seems to be Su-39 currently.

So thats cleared that up

I concur a 100%, I'm just reporting what I read!

Isn't the Su-39 the carrier version?  In LOMAC that's what it is.

LOL..I think the Russians do it just to confuse the hell out of us Westerners....

Ok, I did say that it was a stupid question didn't I??

Well partly it is due to an internal war between two parts of Sukhoi, the Su-27 designers under Simonov and the Su-25 designers under Babak.

Babak designated the Rafale-alike S-37 (internal designation) as "Su-37" for marketing purposes, so Simonov renamed the Su-27M with vectoring nozzles "Su-37".  For good measure Simonov's S-32 (internal designation) Berkut became the S-37,  forcing Babak's Rafale-alike to become "237", and right now  Berkut is  the totally out of sequence "Su-47" I believe.

Babak named the Su-25TM Su-34, and then Simonov renamed the Su27IB Su-34 to spite him.

IIRC the MiG-29M is called "MiG-35", "MiG-33" is the carrier Fulcrum...  

So Mikoyan might well call the 1.42/1.44 "MiG-37"!  B)

Hmmm ... And what's about the MiG-AT

Why did this plane never get a MiG-number

Mikoyan MiG-AT started design as an L-39 replacement in the late 1980s.
Different models were designated 815 (T-tail) and 821, 821 being the design selected in 1992 along with the Yak-130 as a finalist. If selected, it would have been given a "MiG-" designation, perhaps an even number like MiG-32, but the USSR dissolved before that point. As Yak-130 is now the favoured program, the MiG-AT is going for export sales only.
