# SMS G10

SMS G10 was a V1-class large torpedo boat of the Imperial German Navy. She was built by the Germaniawerft shipyard at Kiel between 1911 and 1912, completing on 28 August 1912.
G10 served through the First World War, taking part in the Battle of Heligoland Bight in 1914 and the Battle of Jutland in 1916. Following the end of the war, the ship continued to serve with the Weimar Republic's Reichsmarine and Nazi Germany's Kriegsmarine. In 1936, G10 became a training vessel, and in 1939 was renamed T110. She was scuttled on 5 May 1945.

## Design and construction

In the first decade of the 20th century, the Imperial German Navy had generally ordered twelve large torpedo boats (Große Torpedoboote) as part of each year's construction programme, with a gradual evolution of design in each year's orders, with speed, range and seaworthiness improving year-on-year. These changes resulted in the ships becoming larger, and concerns grew that the torpedo boats were becoming too big to manoeuvre in and out of the battle fleet. For the 1911 fiscal year's orders, it was decided to revert to a smaller design, with the numbering system for torpedo boats restarting as a consequence. As was normal practice, that year's order was split between two shipyards, with six (V1–V6) to be built by AG Vulcan and six (G7–G12) by Germaniawerft, with detailed design differing between the two shipyards.
Germaniawerft's design was 71.5 metres (234 ft 7 in) long overall and 71.0 metres (232 ft 11 in) between perpendiculars, with a beam of 7.56 metres (24 ft 10 in) and a draught of 3.09 metres (10 ft 2 in). Displacement was 573 tonnes (564 long tons) design and 719 tonnes (708 long tons) full load.
Three coal-fired and one oil-fired water-tube boiler fed steam at a pressure of 18 standard atmospheres (260 psi) to two sets of direct-drive steam turbines. The ship's machinery was rated at 16,000 PS (16,000 shp; 12,000 kW) giving a design speed of 32 knots (37 mph; 59 km/h). 110 tons of coal and 80 tons of oil fuel were carried, giving an endurance of 1,150 nautical miles (1,320 mi; 2,130 km) at 17 knots (20 mph; 31 km/h).
The ship was armed with two 8.8 cm SK L/30 naval guns, (replaced by 8.8 cm SK L/45 naval guns in 1916), one on the forecastle and one aft. Four single 50 cm (19.7 in) torpedo tubes were fitted, with two on the ship's beam in the gap between the forecastle and the ship's bridge which were capable of firing straight ahead, and two on the ship's centreline aft of the funnels. 18 mines could be carried. The ship had a crew of 74 officers and men.
G10 was laid down at Germaniawerft's Kiel shipyard as yard number 173, was launched on 15 March 1912 and completed on 28 August 1912.

### Modifications

In 1916, G10 had her guns replaced by 8.8 cm SK L/45 naval guns. In 1921 the 8.8 cm guns were replaced by two 10.5 cm L/45 guns and the ship's forecastle lengthened. From 1928 to 1931, the remaining Germaniawerft-built ships of the class (i.e. G7, G8, G10 and G11) were rebuilt at Wilhelmshaven. They were lengthened to 76.1 metres (249 ft 8 in) overall and 75.7 metres (248 ft 4 in) between perpendiculars, with a beam of 7.58 metres (24 ft 10 in) and a draught of 3.13 metres (10 ft 3 in). Three oil-fired boilers replaced the existing boilers, with speed dropping to 30 knots (35 mph; 56 km/h), but range increasing to 1,900 nautical miles (2,200 mi; 3,500 km) at 17 knots. Displacement increased to 772 tonnes (760 long tons) design and 884 tonnes (870 long tons) full load. On conversion to a training role from 1936, the ship's forward gun was removed and her bridge enlarged. By 1944, armament was a single 10.5 cm gun mounted aft, with two 20 mm anti-aircraft guns.

## Service

On commissioning, G10 joined the 10th Half Flotilla of the 5th Torpedo boat flotilla, and remained in that flotilla in April 1914.

### First World War

G10 was still a member of the 10th Half-flotilla of the 5th Torpedo boat flotilla of the German High Seas Fleet on the outbreak of war. On 28 August 1914, the British Harwich Force, supported by light cruisers and battlecruisers of the Grand Fleet, carried out a raid towards Heligoland with the intention of destroying patrolling German torpedo boats. The German defensive patrols around Heligoland consisted of one flotilla (I Torpedo Flotilla) of 12 modern torpedo boats forming an outer patrol line about 25 nautical miles (29 mi; 46 km) North and West of Heligoland, with an inner line of older torpedo boats of the 3rd Minesweeping Division at about 12 nautical miles (14 mi; 22 km). The 5th Torpedo boat flotilla, together with four German light cruisers, waited near Heligoland in support. The 5th Torpedo Boat Flotilla, including G10, were sent out from Heligoland to investigate sightings of British submarines, and ran into several British destroyers. The Flotilla then turned away to try and escape the trap, but the torpedo boat V1, which along with S13 could not make full speed and lagged behind the rest of the flotilla, was hit by British shells before the arrival of the German cruiser Stettin allowed the 5th Flotilla to escape. The torpedo boat V187 of the outer screen did not manage to evade the British force and was sunk. The intervention of the supporting British forces resulted in the sinking of the German cruisers Mainz, Cöln and Ariadne. The British light cruiser Arethusa and destroyers Laurel, Laertes and Liberty were badly damaged but safely returned to base. G10 was undamaged.
On 7–8 September 1915, the 5th and 9th Torpedo Boat Flotillas carried out a reconnaissance sweep in the German Bight. 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. G10 and V6 assisted when the torpedo boat V3 took V1 under tow.
G10 was still a member of the 10th Half-flotilla of the 5th Torpedo Boat Flotilla at the Battle of Jutland on 31 May – 1 June 1916. The 5th Flotilla supported the main force of the German High Seas Fleet. G10 picked up some of the survivors from the British destroyers Nomad and Nestor, 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). From about 20:15 CET, the German torpedo boat flotillas launched a series of torpedo attacks against the British battle line in order to cover the German fleet's turn away from the British. First to attack were the 6th and 9th Flotillas, followed by the 3rd Flotilla. At 20:38, the 5th Flotilla started an attack run, but it was unable to find the British battleline due to poor visibility caused by fog and smoke, and the attack was aborted. During the night action, the 5th Flotilla was ordered to search for and attack the British fleet, but failed to encounter the British battleships. While G10 and sister ship G9 did spot a "four-funneled cruiser" at about 01:00 on 1 June, they did not engage as they were not certain whether the ship was British or German.
G10 was part of the 5th Torpedo Boat Flotilla during the inconclusive Action of 19 August 1916, when the German High Seas Fleet sailed to cover a sortie of the battlecruisers of the 1st Scouting Group. By late April 1917, the torpedo boats of the 5th Torpedo Boat Flotilla had been fitted for minesweeping and their crews trained in that task, and became increasingly dedicated to minesweeping. G10 remained a member of the 10th half-flotilla of the 5th Torpedo Boat Flotilla at the end of the First World War.

### Postwar operations

G10 survived the war, and was one of the twelve destroyers that Germany was allowed to retain under the Treaty of Versailles. G10 recommissioned into the Weimar Republic's Reichsmarine during 1921, and was deployed to the Baltic. She was modernised in the late 1920s, and was retained in active service after the entry into service of the new Type 23 and Type 24 torpedo boats allowed many of the older boats to be retired or moved to subsidiary duties. In 1932, she was part of the 1st Half-flotilla of the 1st Torpedo Boat Flotilla. G10 remained in service when the Reichsmarine became the Kriegsmarine following the Nazi seizure of power in 1933. She was still part of the active torpedo boat flotillas in 1935. She became a training ship in 1936, and was employed as a tender in a torpedo school. On 23 April 1939, the ship was renamed T110, to free up G10 for a planned class of escort ships.
T110 remained in use in training duties through the Second World War, until she was scuttled at Travemünde on 5 May 1945, shortly before the end of the war in Europe.
