I was surprised that this was missing from the game, being a Russian flight sim and having as many Yaks as it does
Basically, this is a Yak-3 (More specifically a VK-105PF2) with an ASh-82FN Engine. It was meant to surpass all of the other fighters in service.
By the time it was completed in late 1945, it was no longer needed so it didn't enter production.
With all of that what-if 1946 stuff in the game, I think this would be a great addition, and could be done fairly simply as theres plenty of yak-3s to use as a base. Even a franken with the la-7 engine would be nice to have
This page has some good info on it:
