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.
Since S26 series boats had a forecastle. 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.
Modernizations
1942 - 1943, all survived: can carry 4 - 6 mines instead of spare torpedoes
late 1942, S29: - 1 x 1 - 20/65; + 1 x 1 - 40/56 FlaK 28
1943, some: - 1 x 1 - 20/65; + 1 x 2 - 20/65 C/38 or 1 x 4 - 20/65 C/38, 1 x 1 - 20/65 C/38 or 1 x 2 - 15/84
1943, all survived: main engines were forced to 7500hp, maximal speed increased to 41kts.
Naval service
S26 20.8.1944 was sunk by Soviet aircraft at Sulina; S27 was lost 5.9.1942 as result of hit of faulty torpedo from S72 off Taman; S28 20.8.1944 was damaged by Soviet aircraft at Constanza and scuttled by crew 25.8.1944 at Varna; S29 was sunk 29.3.1943 by British escort destroyers Blencathra, Windsor and MGB321 and MGB333 in La Manche.
