Pre Revolution Warship Classes

[khymerion]

Some of the few remaining warship classes in the fleet roster that were pre-revolution and survived...  Their former titles of being Baltic League warships have been replaced with their new designations.  These older ships showed quite well the League and its successor, the Confederation's, love of heavy armor.

Not the best boats ever built and cramped but they were good at the jobs that they did, keeping the frigid waters patrolled and assisting fishing ships and freighters caught in rough waters.  Their small size was also purpose built for possible production in overseas yards with most of the parts being easy to come by.  Never utilized in this role though.
