SMS S17 (1912)

SMS S17 was a V1-class torpedo boat of the Imperial German Navy. The ship was built by Schichau-Werke, at their Elbing shipyard, completing in 1912. S17 served with the German High Seas Fleet during the First World War, taking part in the Battle of Jutland in 1916. She was sunk by a mine on 16 May 1917.

Construction and design
In 1911, the Imperial German Navy decided to break the pattern of each year's orders of torpedo boats being a development of the previous year's designs, as it felt that they were getting too big to work for the fleet, and instead the 12 torpedo boats (six each ordered from AG Vulcan and Germaniawerft) (the V1-class) were smaller than those ordered in recent years in order to be more manoeuvrable and so work better with the fleet. This change resulted in the numbering series for torpedo boats being restarted. The 1912 programme placed orders for a flotilla of 12 torpedo boats of similar design (SMS S13 (1911) to SMS S24 (1913)) with Schichau-Werke. The reduction in size resulted in the ships' seaworthiness being adversely affected, however, with the 1911 and 1912 torpedo boats acquiring the disparaging nickname "Admiral Lans' cripples".

The Schichau boats were 71.5 m long overall and 71.0 m at the waterline, with a beam of 7.43 m and a draught of 2.77 m. Displacement was 568 t normal and 695 t deep load. Three coal-fired and one oil-fired water-tube boilers fed steam to two direct-drive steam turbines rated at 15700 PS, giving a design speed of 32.5 kn. 108 t of coal and 72 t of oil were carried, giving a range of 1050 nmi at 17 kn or 600 nmi at 29 kn.

S17's armament consisted of two 8.8 cm SK L/30 naval guns in single mounts fore and aft, together with four 50 cm (19.7 in) torpedo tubes with one reload torpedo carried. Up to 18 mines could be carried. The ship had a crew of 74 officers and other ranks. In 1916, the guns were replaced by more powerful 8.8 cm SK L/45 naval guns.

S17, yard number 868, was launched at Schichau's shipyard in Elbing, East Prussia (now Elbląg in Poland) on 22 June 1912 and was commissioned on 7 December that year.

Service
In May 1914, S17 was part of the 13th half-flotilla of the 7th Torpedo boat Flotilla.

First World War
S17 remained a member of the 13th half-flotilla of the 7th Flotilla, part of the German High Seas Fleet, at the outbreak of the First World War in August 1914. The 7th Torpedo Boat Flotilla supported the Raid on Yarmouth on 3 November 1914 and the Raid on Scarborough, Hartlepool and Whitby on 16 December 1914. On the night of 19/20 December 1915, the two torpedo boats SMS S22 (1913) and SMS S23 (1913) of the 7th Flotilla stopped the Swedish steamer Argo, suspected of carrying contraband to Russia near Simrishamn on the East coast of Sweden. Argo rammed S22 and made off, with the two torpedo boats not opening fire as the commanding officer was unsure whether they were in Swedish territorial waters. The Flotilla commander disagreed, arguing that Argos's hostile actions authorised the use of force, and ordered S17 and SMS S15 (1912) to intercept Argo and to use "all means" to capture the ship. Argo was seized at Utlängan in Swedish waters, and taken to the German port of Swinemünde (now Świnoujście in Poland) but was released after a few hours.

S17, as part of the 7th flotilla, was part of the High Seas Fleet when it sailed to cover the Lowestoft Raid on 24–25 April 1916. At the Battle of Jutland on 31 May–1 June 1916, S17 was still part of the 13th Half-flotilla of the 7th Torpedo boat flotilla, operating in support of the main German battle fleet. S17 picked up some of the survivors from the British destroyers HMS Nomad and HMS Nestor (1915), which had previously been disabled and then sunk by fire from German battleships at about 18:30–18:35 CET (17:30–17:35 GMT). During the night action, the 7th flotilla was ordered to search for and attack the British fleet, being allocated the sector to the south-east of the German fleet. The speed of the ships of the 7th flotilla, (and those of the 5th Flotilla, patrolling the adjacent sector) was limited to less than 17 kn by the need to minimise the production of smoke and sparks which would give their location away in any confrontation at night, and by the tiredness of their stokers, as the ships had been operating at high speeds for most of the preceding day. As the British fleet had a night cruising speed of 17 knots, this would limit the 7th Flotilla's effectiveness. The 7th Flotilla briefly clashed twice with British destroyers during the night, but no ships on either side were damaged in these clashes and S17 did not open fire.

S17 was transferred to coastal defence duties in 1917, and on 16 May 1917 was sunk by a mine in the North Sea (53.56667°N, 5.93333°W), that had been laid by the British submarine HMS E34 on 12 May. Twenty-six of S17's crew were killed, and the minesweepers T78 (an old torpedo boat) and SMS M14 were mined and sunk that day in attempts to salvage S17. In total eight ships were claimed by this small minefield of 20 mines by the end of June.
