Battleship Novorossiysk

We can find Novorossiysk( The battleship that Italy gives Russia after WWII) in unpacking of 2.33, But does anyone know it will be a researchable vehicle or premium?

I was going to believe it was the winter event reward, bu I felt a premium made more sense, yes they did get one back in Sons of Attila, but I felt a reparation ship isn’t a good idea for TT since the Russians has plenty of choices.
It’s a conte after all not a lot of upsides
