Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
Then I decided "The French need it more, actually." So I loaded her up with 120s instead of 130s, and 40mm AA instead of 37mm, trimmed her dimensions some, and yes, she's very similar to the Bush class...
And to prove it, note the torpedos... The Russians use 530mm, the French use 550mm...
