This isn't place for that discussion my dear "the closest by the lore allies", so it's my last message regarding it: you don't produce those all big RM ships; Daumann does it. When inforcard says: "after the destruction of the Navy during the 80-Years War and the economic crash that followed, Daumann has been forced to transition into the less lucrative fields of commercial and civilian ship construction", it doesn't say we stopped constructing valkyries and turtles, it says because of economic problems RM no longer ordered bazillion of ships, so DHC had to start constructing transports to still be that profitable.
And Alster really doesn't produce any RM ship, it's civilian shipyard.
