SM UB-18 was a German Type UB II submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 30 April 1915 and launched on 21 August 1915. She was commissioned into the German Imperial Navy on 11 December 1915 as SM UB-18.[Note 1] The submarine sank 128 ships in 31 patrols for a total of 130,841 GRT and 725 tons,[3] making her the 17th most successful U-boat in both world wars. UB-18 was rammed by the trawler Ben Lawer and sunk in the English Channel at 49°17′N 5°47′W / 49.283°N 5.783°W on 9 December 1917.[2]

Design
A Type UB II submarine, ‘’UB-18’’ had a displacement of 263 tonnes (259 long tons) when at the surface and 292 tonnes (287 long tons) while submerged. They had a length overall of 36.13 m (118 ft 6 in), a beam of 4.54 m (14 ft 11 in), and a draught of 3.70 m (12 ft 2 in). The submarine was powered by two Daimler six-cylinder four-stroke diesel engines each producing 142 metric horsepower (104 kW; 140 shp) (a total of 284 metric horsepower (209 kW; 280 shp)), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft. She had a dive time of 45 seconds and was capable of operating at a depth of 50 metres (160 ft).[2]
The submarine had a maximum surface speed of 9.15 knots (16.95 km/h; 10.53 mph) and a submerged speed of 5.81 knots (10.76 km/h; 6.69 mph). When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced she could travel 6,650 nautical miles (12,320 km; 7,650 mi) at 5 knots (9.3 km/h; 5.8 mph). UB-18 was fitted with two 50 centimetres (20 in) torpedo tubes in the bow, four torpedoes, and one 5 cm (2.0 in) Tk L/40 deck gun. Her complement was twenty-three crew members.[2]
Service history
Oberleutnant zur See (Oblt.z.S.) Franz Wäger took command of UB-18 upon commissioning on 11 December 1915. Wäger handed over command to Oblt.z.S. Otto Steinbrinck,[Note 2] who sailed her to Zeebrugge, arriving on 16 February, the first U-boat of the type to be based there.[4]
1st War Patrol
At the end of February 1916, UB-18 left Zeebrugge for the approaches to Le Havre. On 26 February she launched a torpedo hitting the French steamer SS <i>Charbutier</i>, whose sinking was not observed. The attack on the French auxiliary minesweeper Au Revoir was more successful, sinking the 20-year-old ship of 1,058 GRT, killing 18 crew members. UB-18 returned to base arriving there 29 February 1916.[4]
2nd War Patrol
On 4 March 1916 UB-18 provided flank cover for a German fleet sortie against the English east coast.[4]
3rd War Patrol
From 7–11 March 1916, UB-18 operated against Allied shipping off Boulogne and Le Havre. On 8 March, she sunk a British steamer, SS <i>Harmatris</i>, and the following day, a Norwegian freighter, the Silius, and a French steamer, SS <i>Louisane</i>, fell victims to UB-18's torpedoes.[4]
4th War Patrol
On 21 March 1916, UB-18 left Zeebrugge again for the Le Havre area, where she successfully attacked ships lying in the roads. Two ships, the British freighter SS <i>Kelvinbank</i>, and the Norwegian steamer SS <i>Kannik</i> were hit by torpedoes and sank. The two reloads did not show any hits. UB-18 returned to Zeebrugge, arriving on 29 March 1916. That day, the Flanders Flotilla was formed, and Steinbrinck was awarded the coveted Pour le Mérite order.[5]
Loss
Sailing on her last patrol, she was seen off Start Point, Devon by SM U-84 on 4 December 1917, bound for the Western Approaches. Early on the morning of 9 December she inadvertently surfaced close to the trawler Ben Lawer, which was escorting a coal convoy. The trawler immediately rammed her just aft of the conning tower, sinking her; there were no survivors. The impact was substantial, with the Ben Lawer so badly damaged that she only just made port.[6]

Notes
- ^ "SM" stands for "Seiner Majestät" (English: His Majesty's) and combined with the U for Unterseeboot would be translated as His Majesty's Submarine.
- ^ Steinbrinck was the most successful of the Flanders U-boat commanders. After the war he joined the Flick group and became a leading industrialist. In 1933 he joined the Freundeskreis Reichsführer SS. He was indicted in the Flick Trial at Nuremberg in 1947 and found guilty of membership in a criminal organisation.
- ^ Merchant ship tonnages are in gross register tons. Military vessels are listed by tons displacement.
