Both, 41-3 and 201, were supposed to feature IWB for a total of four R-77 missiles.
On the 41-3 these were located in the wing nacelles; on the 201 they were positioned under the fuselage (one deep IWB).

[jajeczko]

Does that mean they were planning to use the L-150 Pastel?

 

[overscan (PaulMM)]

L150 Pastel is a radar warnng receiver. What on earth has that got to do with the flight control system?

 

[jajeczko]

Because it has the ESM and is newer than the SPO-15. They installed the L-150 on the Su-25T, which is why I'm wondering and looking for information on whether they planned to do the same for the Yak-141 as well.

 

[overscan (PaulMM)]

Let me guess, this is for a computer game?

Your source posted in the Pastel topic was a wargames manual. You don't seem to understand why planning for a digital flight control system doesn't speak to having a new RWR.

The Yak-141 never made it past prototype stage. Having said that, if the Yak-41M had entered service, it would undoubtedly been fitted with the L-150 Pastel and the Zhuk radar, like the MiG-29M.

 

[jajeczko]

Yes. And besides, I love that plane.

from Yefim Gordon book.
And the ESM is unique to the L-150

Thanks,but this was Yak-141 with 1 R-79M + 2 RD-41 engines,and acctually built,but
I speak about Yak-41 as attack project version,with 1 R-79-300 + 2 RD-41 engines,
which never built.

 

[overscan (PaulMM)]

Yak-41 = Yak-141.
Yak-41/141 used R79V-300 engine. R-79M was planned upgraded version.

Not sure what you have been smoking.

Former Volunteers of the Air Force Museum in Monino, Russia, are refurbishing the front section of a wooden model (mock-up).
It seems to be the trainer project Yakovlev Yak-41UT.

Hey folks, in April 2025, the front section of a wooden model (mock-up) of the Yakovlev Yak-41UT trainer project was installed in the lobby of the MFUA Children’s Educational Technopark in Kuntsevo.
Here some more pictures by Алексей Калмыков and Илья Аксарин.
