This is a single ship example of a Visby class stealth missile corvette used by the Swedish Navy.
Simple one piece model design for 3D printing in versatile white plastic only at this scale.
Based on a design by J.Andersen and modified by Martin Rait for Shapeways printing and should be a full hull below waterline design that could be used for Radio Controlled Combat enthusiasts who'd like to cut this apart and make a suitable mini warship for battles.
