From my understanding the hull wall partially completed and the gun was tested on a ground platform so what from this is unrealistic?
Currently, the Sovetsky Soyuz has a maximum armor thickness of 420mm of rolled cemented armor, even though the Soviets were unable to make cemented armor thicker than 230mm. So this isn’t the case of “the war ended before it could be complete” or “they had a material shortage”. Even if the war had continued and materials weren’t an issue, Soviet shipyards were literally unable to complete the ship as it is in game. I’m fine with them keeping the 420mm plates, but the armor type should be changed at the very least.
Also how is possible to build a shell, that is 110kg lighter than the Iowa’s, has nearly around the same pen as the Iowa’s yet has double (21kg more) the explosive mass?
The round is overperforming even compared to the official numbers. The official Soviet stats for that round was that it could pen a 406mm plate at 25 degrees from 13.6km away. On dev, it’s currently at 450mm at 30 degrees from 15km, so a considerable increase. I’m too lazy to do the actual math, but I’d assume it’s max pen should be more like 770 or so, compared to the 852 it is right now.
As for the explosive mass, they use A-IX-2 which has a crazy TNT equivalent, at least according to whatever source Gaijin uses, so while it only has 25kg of explosive, this translates to the current 39.58kg
Was Russia’s Navy really that advanced and ahead of it’s time?
Not at all. The Soviet navy was quite weak in WW2 compared to pretty much every other major power. In terms of large ships, they only had a total of 3 battleships and 7 cruisers, many of which were from WWI. You can get a pretty good sense of this already from the ships we have in WT. 5 out of the 8 BBs in the tech tree are either project ships that were never completed or were ships from other nations that ended up in Soviet service one way or another.
The armor is honestly what annoys me most about this whole thing. I don’t mind fake ships being added. In fact, I’d love to see some other iconic designs that never made it to completion like the German H-class and Japanese A-150s. But to not only make the fake ship based on all these “ideal” values but also be the best ship in the game is quite annoying. These paper ships should be worse if anything, than how we might estimate them to have performed IRL, since there are so many factors that could’ve influenced how they’d have performed if they were actually built.
