For my fleets for Victory at sea, 1/3000 scale, I add four new ships.
I was buying Navwar ships for my Japanese, German and USa fleets, this company make excellent models for WWI and WWII wars, but those models are from Skytrex.
The models are very good, but I think are smaller than navwar. But this is not a problem to mix miniatures form both companies in your fleets.
They are very easy to paint, and look very nice whith more ships sailing to meet the enemy fleet!
