It’s been a long time since Gaijin sticks on ‘one ship, one configuration’. This means that if one ship comes into game of specific year configuration, that ship’s modernized or pre-modernized configuration cannot be in game. This was okay when ship class was limited in coastal, destroyer and cruiser. Usually those kind of ship classes were built with at least two sister ship, so Gaijin could fill tree and line-up freely. Of course there is case of IJN Yubari and Tashkent, but they are really rare cases.
But Capital ships, I mean, battleships and battlecruisers, were not the case. Some of this ships were composed of only two ships per class, and their performance significantly differs between pre-modernization and post-modernization. In worst case, one nation can lost chance of making stable lineup because one ship comes in pre-modernization, and other ship came in post-modernization.
My thoughts on this gets bigger recent days as Italian and Japanese fleet shows signs of this. Dante Alighieri/Andrea Doria at 6.3, Duilio at 6.7, and Conte di Cavour at 7.0 makes this nation’s 6.7 and 7.0 lineup very deformed. Maybe Guilio Cesare at 7.0 could make Italy at least getting proper 7.0 lineup, but it goes to USSR, who is also short of capital ships. Breaking ‘one ship one configuration’ rule can give Andrea Doria modernized version at 6.7, and Guilio Cesare WW2 version in 7.0, finally making stable lineup for Italy.
Japan is also other nation that would need new rule. Gaijin making terrible mistake of giving IJN Mutsu as 1922 version, making Nagato the only Japanese modernized 16’’ battleship. As modernization of Nagato class gives magnificent increase in turret/turtleback armor and firepower, ‘loss’ of modernized Mutsu would be very bad news for Japanese fleet. Even Kaga class and Amagai class retain fragile 305 mm turret frontal armor of current Mutsu. Japan needs both 1922 and 1943 version of Mutsu if they dont want to be fall behind in 16’’ age.
Great Britain would be the nation that is not in such situation right now, but would be in future. Nelson class is composed of only two ship, and HMS Nelson(1945) is having the best AA among all British WW2 capital ships, which her sister ship, HMS Rodney cannot gain in her entire life. It is not confirmed which version of HMS Nelson would come, but if HMS Nelson gets like 1942 version or inter-war version, GB players would also need ‘one ship multiple configuration’
