It is accurate to the point that, for instance, the painting in the wardroom of the model exactly replicates the original not only in subject but also in the painting technique (oil on canvas). The collection documents the first k.u.k. navy pilots such as Gottfried von Banfield, and the fate of the submarine fleet in World War I. Particularly noteworthy is the only surviving fragment of a k.u.k. submarine, the sail of U-20, which was sunk in 1918 in the estuary of the Tagliamento River and salvaged in 1962. The exhibition reaches its logic conclusion with the models of the Danube fleet, the so-called Donaumonitore, which had to be surrendered to the SHS-state on 31 December 1918.
