The "KS"-Boats of the 22. Schnellbootflottille, which were stationed in the Adria, were handed over to the Kroatik Navy in fall 1944 were taken back by the Kriegsmarine upon the trial to desert to the partisans. They finally became war-loot of the UdSSR. Their whereabouts is unknown.
"KS" stands for Kleinschellboot (smal S-boat). During their reconstruction the minelyinggear was removed and two 45-cm-torpedotubes were installed instead.
The other KS-boats were transported to the Peipssea Estland, where most of them became war-loot of the UdSSR in 1945.

Reinhard Plate) burst in fire 2 miles south of Piave Vecchia lighthouse on the march from Lignane to Venice in order to take over torpedoes propably by a shortage in the fuelreplenishment-measurement system of the middle-tank.
