Alright, don't kill me now, this is something of weird question.
The Ravens reactivated their mothball fleet, with what?
The OWA has no industrial base, and most of the Snow Raven industrial base got ripped or spaced by the Snake Clans. Their one, lone shipyard got the Word-of-Blake sponsored makeover, and nobody's been building anything. They didn't integrate the economy in their territory, so no industrial development there...
Warships are incredibly expensive machines and even the ammunition is complex and expensive to build, never mind the armor plates you're not going to be able to make, transport, or mount on expedition.
and structure? yeah, they don't have the ability to make that either.
This doesn't even touch on the thousands of kilometers of piping, wiring, data runs, and auxiliary power plants needed to bring a warship up to speed (think "Your heat-sink stat" as explained away via power distribution in some of the canon...)
So...where did they get the stuff to bring those ships up to operating capability, and where are they going to get the spare parts and ammunition to keep them in operation?
It's not like there's even a naval stores location they can raid-nobody else has that stuff either. (eh, well, maybe the Diamon-I mean Sea Foxes might have some...)
just a little thing niggliung at the back of my mind.
