Sounds fine to me. When you're done, we'll look them over, and we can figure out if they need any changes.
As a personal suggestion, I'm thinking the highest title would be
trierarch; it'd be an adaptation of an ancient
Tionese word, in this case taken to mean something like a
Grand Admiral.
Triter Zone, for example, is the Trierarch of the Line.
As our fleet will be one of our greatest strengths, I would say naval ranks would be a good starting point; archaic ones would be best, translated to modern equivalents.
