I like the idea of additional ship types

I don't think we should be allowing them to be limitless from a spawn standpoint
Maybe allow
more than one fleet for each port. This will give the mapmaker the opportunity to mix in a larger variety in fleets. The second fleet will not have a CV that they are escorting, so
both fleets will still be captured in the same way, by sinking the associated CV while owning its port. The second fleet also, could have
multiple rolls, to set up pickets, to escort the main (carrier) fleet, to recon positions of enemy fleets, etc.
