Here are some uncompleted Imperial Russian warship projects I found on navypedia, any technical drawings, evidence of not being real, further info, or art of these would be greatly appreciated
Thinking that we need a thread for all old (pre-1880s?) projects.
Came across HMS Duke of Kent design for a four-deck ship of the line on Reddit. c1809. Never built. Original source http://collections.rmg.co.uk/
