I translated the latin phrase. In English is "All safe always", in Hellenics/Greek it could be "Αίεν Προστατεύειν"-Always Protecting, with initials. The A-class could be the base for an RHN AU destroyer and there is available in a webpage in SB-scale (credited by ALVAMA/Nigevids).
The badge itself could be modified a little to represent the helmet of Achilles (Hero of Troy) and named "A/T Αχιλλεύς", name in initials. The ideal font would be Ancient Greek-like, but Arial could work.
So, I have a ship class to work on for my AU. All these from a badge!
