I was reading about the Resurgent-class Star Destroyer Finalizer, the First Order's destroyer shown in The Force Awakens, when something struck me as odd. The official site starwars.com describes it as
The first of the new Resurgent class constructed in violation of treaties with the New Republic [...]
So the Finalizer is the first Star Destroyer of the Resurgent class. This is odd. According to real-world European and American conventions, a military ship's class is usually named after the first (or the leading, or at least one of the earliest) vessel of its kind. There are some exceptions (some countries use numbers or single letters), but when there is a name, it's almost always the name of the first of the class. Therefore, I would have expected the first ship of the Resurgent class to be named Resurgent!
Whatever the real-world convention, it seems the Old Republic, the Galactic Empire and the First Order don't use it. There is no Venator, Acclamator, Victory, Imperial/Imperator or Resurgent names for prominent or leading ships of their corresponding classes, as far as I can see (that is, reading Wookieepedia). Which brings me to my question.
What is the naming convention used for classes of capital ships like Star Destroyers?
