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. S2 type boats were appeared unsuccessful because of their petrol engines.

Modernizations

None.

Naval service

S3 and S5 were badly damaged at Cadiz during unloading from cargo vessel and never commissioned by Spanish navy.
