Crovenia's ally Skyria (The France/Germany/Britain) recently lost it's larger shipyards in a war, and ordered ships from Crovenia to reinforce their navy.
Don't want to pick holes in a story but any power that holds F/G/B must be a very strong sea power and it would almost certainly have docks on both GB and at the end of the Rhine ? (v a Ukraine, mainly Land power with much less needs for ship = less dockyards ?)
The destroyer looks nice and fits 1901.
