Russia officially built only one SSJ in 2024 – RA-89192. But in fact it was originally built in 2022 and it is probably the last SSJ-100 ever produced.
There is no such thing as an SSJ-100 with Russian-made engines, period. Airlines cannot buy them, and you cannot fly them. Even the MC-21 is slightly more realistic, but it is also not available to any airline.
We have been hearing this never-ending story of "aircraft will be available in 2 years" for a very long time. :)
Yes, of course. The version of SSJ-100 with Russian-made engines and other systems is called SJ-100.
