Nuclear weapons and individual control in Azur Lane

What would governments consider before giving Azur Lane ship characters modern weapons, including nuclear weapons?

The main concern is concentrating nuclear power in a single sentient individual whose personality complicates trust.

Arming an individual ship character with nuclear weapons concentrates enormous destructive power in one person's hands. Fictional Iowa-class characters supply an example because updated equipment could include nuclear Tomahawks. This is a hypothetical modernisation rather than an established game capability. Character personalities complicate the trust needed for such authority. British submarine officers' nuclear authority raises a related command question.
