Project history: Torpedo motorboats (Schnellboote) were the development of successful prototype created by F. Lürssen in 1929. General characteristic lines for all series were round-bilge hull with small deadrise, triple-shaft diesel machinery, presence of two auxiliary rudders for creation of "Lürssen effect" (fitting of rudders under an angle to centreline for speed increase) and a bow arrangement of two TTs. Composite hull included light alloy framing, wooden planking and steel engine seating.

Boats had a forecastle; there were conical deck houses, which were protected by 10-12mm armour. Besides two torpedoes in tubes, all S-boats could carry two spare torpedoes (or 4-6 mines). Artillery in days of war was continuously strengthened.

Ship protection: Boats had armoured CT and bridge.

Modernizations: None.

Naval service: One boat of S170 class was lost: S301 was sunk 7.5.1945 as result of collision with S191 in the North Sea. On reparations 1 boat was transferred to the USSR, 2 to Norway and 2 to Denmark.
