Hope no new gremlins creeps in!
I did notice some errors with the Soviet ships as well. This is probably not something that matters as you usually don't see much of them in action. These errors are present in the stock scenarios as well.
In fact there's so much odd going on there that I don't know where to start. I'll be lazy and simply give you the navypedia links instead of pointing out exactly every thing. Of course navypedia isn't an infallible source but it's usually quite accurate. Still as always take things with a grain of salt.
Kalinin and Kaganovich are of the Kirov-class ingame, in reality they were a slightly larger type: http://www.navypedia.org/ships/russia/ru_cr_maxim_gorkiy.htm - change the Kirov-class to this.
The Leningrad-class has some incorrect weapons, among others 2x2 torpedoes rather than 2x4. http://www.navypedia.org/ships/russia/ru_dd_minsk.htm - check this to correct it (Tblisi is the ship in the game)
Most of the Gnevnyi-class ships in the Pacific seems to have had 3x1 or 4x1 37mm guns, not 1x2 as currently. http://www.navypedia.org/ships/russia/ru_dd_gnevnyy.htm
The two ships represented by the Novik-class probably didn't have DP guns or 533 mm torpedoes. See http://www.navypedia.org/ships/russia/ru_dd_pobeditel.htm (Stalin) and http://www.navypedia.org/ships/russia/ru_dd_kapitan_izylmetyev.htm (Voykov), check the outfits at 1946.
The 180mm/57 gun seems to lower penetration than I'd expect. Something along the lines of 275 might be more correct. That might sound like a lot for something that's not a 203 mm gun, but it's a rather high velocity gun. The Japanese 15.5 cm gun already has 231.
The 130mm/55 should be 130mm/50. The penetration here is also low, it should probably be around 90+, upper bound probably in the vicinity of 110.
102mm/60 P1911 - used on the Novik-class. Guess at stats:
Type: Naval Gun, Range: 17, Accuracy: 40, Penetration: 48, Effect: 38, Ceiling: 0, Anti-Armor: 24, Anti-Soft: 22
I'm somewhat unclear as to whether the 100mm/56 P1940 was used on any of the ships in the Pacific. It might very well have been used in the coastal forts though (it's currently in the Vladivostok fort as an example). So the device should probably stick around but an additional gun added.
100mm/56 B-24 - replaces all instances of the 100mm/56 P1940 gun on ships.
Same stats as the P1940 except it's a single purpose gun, not a DP gun.
85mm/52 90K - used on the two cruisers. Guess at stats:
Type: DP Gun, Range: 17, Accuracy: 36, Penetration: 36, Effect: 20, Ceiling: 33450, Anti-Armor: 18, Anti-Soft: 17
(If using witploadAE extra stats - AA Penetration: 18, AA Effect: 24, AA Accuracy: 50)
As an curiosity I don't really get why three of the Soviet classes are given a 18 knot cruise speed, rather than the normal 15.
