The Zoners however would sell battleships to the IMG. Which allows them to use Zoner Juggernaut, Battlestar I (BSA) and BSA. So now they would have battleships.
Also, the militaries can't force other factions (speaking of RP NPC factions, and what their reactions would be) to give up salvaged ships. Look at the IMg battleship in Dublin. Battleship Hood is a salvaged Bretonia Battleship, yet the IMG have control of it.
So if there is a proper RP reason they can get salvaged/stolen ships as well.
After getting a shiplist I might also be doing ships by rank, but not very restricted on that part. Pretty much be Caption + for cruisers or higher, if your under that your gunboats, bombers, fighters, and combat freighters.
