Eeeee.... this is a tough. The BB is Neptun Arizona, I think; the CL the Neptun Fargo. Then there are the DDs... both Neptun, I think. But the relationships? I'm stumped. Not the same place at the same time... and I'm having no luck with geographic name relationships or ship's personnel... Anyone else having better luck? I hope I'm not missing something embarrassingly obvious.

What is an important linkage among these ships? Name the link, the ships, and the models. Two are portraying themselves and two are near sisters to the intended vessels.
