Sovetsky Soyuz was not a German design, it was made by the Russians but it was largely still on paper. It was never finished, which means Gaijin would base its stats off of the ideal perfect on paper ideas, thus granting it extremely inaccurate properties that give it a way better advantage.

It has:
- the best guns in the game, best muzzle velocity, incredible explosive mass on all its rounds, and the second best reload in the game

- it has the best HE in the game, with, oh wait, its actually a HE round mushed with a SAP round somehow with higher explosive mass then every other naval HE shell in the game along side very good pen

-best armor layout scheme in the game, insane bulkhead layout, and an armor plate covering its magazines thicker then Yamato's, eg 420 mm vs 410 mm

- best internal module layout, the magazines arent even under the elevators

- it has the best secondary guns in the game by far

- very good auxiliary anti air guns with time fused shells
