Azur Lane's diverse characters and the Royal Navy's crews

Would the ethnic backgrounds of Azur Lane's shipgirls create difficulties for historical Royal Navy officers?

Little difficulty is expected, because of the Royal Navy's experience with varied crews and its practical need for skilled personnel.

The Royal Navy's mixed crews are offered as a reason to expect adaptation within the fictional scenario. Examples include Irish sailors and personnel recruited locally for ships operating in Indian waters. The argument places practical demand for skills ahead of appearance. A wartime example concerns British pubs responding to American demands for segregation by welcoming Black soldiers instead. HMS New Zealand supplies another example of officers adopting local cultural symbols. These examples support a counterfactual judgment about the officers' response to fictional characters; they do not establish that historical racial prejudice was absent.
