1. (Military) the warships and auxiliary vessels of a nation or ruler"
Just to make sure everyone understand what the word "navy" means.
First of all commonly =/= always so your first argument doesn't stick.
The Corsair Empire is a nation and has warships, so all of the Empire's warships = the Empire's navy. The second definition includes the word "ruler" so you don't need a highly organized state-like structure to call the total of your ships a navy.
A Navy is not a mere plural form meaning "lots of warships" as your brilliant understanding tells you.
A Navy is a military force, part of a regular military, that serves a nation, empire, commonwealth, dynasty, or [insert Vito's own nightmarish armed force here]. Since the Corsairs do not maintain a regular military force as I'm tired to point out, they do not have a real Navy. Navy is not a group of warships. We have a group of warships that fight for a common goal.
That does not mean we have a regular Navy to refer to our vessels as "Naval Ships".
Oh, and by the way, the Corsairs are not an "Empire". That is a gamer's Starwars-gasmic dream of calling someone "Emperor" that regrettably spread like wildfire. (tell me where in the lore we find the words Emperor, Empress, King, Queen, or Lord Vito).
The Corsairs are a Nation.
