maybe the new russian ECV 7.5 ? https://www.sinodefenceforum.com/russian-cv-063-kuznetsov-in-1-350-scale.t6875/

In real life, this is a heavy carrying aircraft-cruiser pr.1143.5 "Krechet". The only ship on the move in the Russian Navy "Admiral Kuznetzov"

What this can mean in the game is known only to developers. In the set of sprites a standard client for a long time are the sprites of the bombers of the 3rd set. There were also images of the launching of Tomahawk cruise missiles from ВВ Iowa's. Perhaps this fake or drawings of the players themselves.

Could be Chinese Liaoning CV (former Varyag, sold in 1998). Chinese nation would be logical for attracting more Chinese players in the game...if any work was being done here, of course.
The existing nations are more than enough anyway. 

Una bellesa de la armada Rusa ....

ME gustaria que el juego tuviese mas sprite propios y no repetidos!

ARA Independencia (V1)

except for the red paiint, that looks almost exactly like the chinese cv, as it was when bought from russia, by china.  china was involved on allied sides in WW2.

new nation will be china...and interesting...cause all will be fantasy ships or based on current fleet.

ARA Moreno (Acorazado clase Rivadavia)
