She served in the First World War with the German High Seas Fleet, taking part in the Battle of Jutland.
The reduction in size resulted in the ships' seaworthiness being adversely affected,[2] with the 1911 torpedo boats and the similar craft of the 1912 programme acquiring the disparaging nickname "Admiral Lans' cripples".
[1][3] In July 1912, shortly before the outbreak of the First Balkan War, two of the under-construction 1911 Vulcan torpedo boats, V5 and V6 were sold to Greece as part of an urgent programme to build up the strength of the Greek Navy, becoming Keravnos and Nea Genea.
The new V6, yard number 320, was launched from Vulcan's Stettin, Prussia (now Szczecin in Poland) shipyard on 28 February 1913 and commissioned on 17 May that year.
[3] 107 tonnes (105 long tons) of coal and 78 tonnes (77 long tons) of oil were carried, giving a range of 1,190 nautical miles (2,200 km; 1,370 mi) at 17 knots (31 km/h; 20 mph) or 490 nautical miles (910 km; 560 mi) at 29 knots (54 km/h; 33 mph).
[9] On 2 November 1914, German battlecruisers and light cruisers, with an escort of torpedo boats of the 3rd, 5th, 6th, 7th and 8th Torpedo Boat Flotillas left port to shell Great Yarmouth and lay mines off the British East Coast, with V6 part if the 5th Flotilla.
[13] On 7–8 September 1915, the 5th and 9th Torpedo Boat Flotillas carried out a reconnaissance sweep in the German Bight,[14] with V6 leading the 9th Half-Flotilla.
On the morning of 8 September 1915, when about 20 nmi (23 mi; 37 km) south of the Horns Reef lightvessel, the torpedo boats V1 and G12 collided, sinking G12 and badly damaging V1.
