Basically Girls und Panzer but with ships. Military setting where a bunch of cute school girls are put in charge of serious military hardware. I'm no expert on tanks or ships, but both shows appear to try to be serious about portraying actual piloting their tanks/ships, requiring all the crew to work together with a leader who is a very good person but lacks confidence in themself.
