Description

edit

The ship was 93.57 metres (307 ft 0 in) long, with a beam of 13.84 metres (45 ft 5 in). She had a depth of 5.97 metres (19 ft 7 in) and a draught of 6.63 metres (21 ft 9 in). She was assessed at 2,448 GRT, 1,435 NRT.[1]

She was powered by a four-cylinder compound steam engine, which had two cylinders of 478 millimetres (18+13⁄16 in) diameter and two cylinders of 1,000 millimetres (39+3⁄8 in) diameter by 1,000 millimetres (39+3⁄8 in) stroke. The engine was built by A. Borsig GmbH., Berlin. It was rated at 272 nhp and drove a screw propeller.[1] It could propel her at 11.5 knots (21.3 km/h).[2]

When operated as a Sperrbrecher, the ship was armed with two 10.5 cm SK L/45 naval guns, six 3.7 cm anti-aircraft guns and four 2 cm anti-aircraft guns.[3]

History

edit

Schürbek was built as yard number 418 by Flensburger Schiffbau-Gesellschaft, Flensburg for Knöhr & Burchardt, Hamburg.[2] She was launched on 10 April 1930 and completed on 3 June.[4] Her port of registry was Hamburg and the Code Letters RHPN were allocated.[1] In 1934, her Code Letters were changed to DHUU.[5] On 19 August 1939, Schürbek collided with the Portuguese steamship Corte Real at Rotterdam, Netherlands. Both vessels were damaged.[6]

On 5 September 1939, she was requisitioned by the Kriegsmarine. Allocated the pennant number TS(K)2 and designated Schiff 40, she was allocated to 6 Vorpostengrüppe on 23 December as a Q-ship. On 20 January 1940, her pennant number was changed to TS(K)1. Schürbek was placed under the control of the Führer der Sonderverband West.[4][7] On 10 April 1940, Schürbek was attacked by the British submarine HMS Tarpon west of Jutland. Tarpon's torpedoes missed, and Schürbek and the minesweeper M18 delivered a sustained depth charge attack over several hours, which sank Tarpon.[8] On 12 April 1940, Schürbek was torpedoed and damaged in the Skaggerak by the British submarine HMS Sunfish.[4][9]

She was under repair from 10 September to 19 December, and was recommissioned as the auxiliary minesweeper Sperrbrecher 18,[4] joining the 3rd Sperrbrecherflotille, operating off Norway and in the Baltic.[7][10] On 12 March 1945, Sperrbrecher 18 was severely damaged in an American air raid on Hamburg and was declared a constructive total loss. Although allocated to the United Kingdom post-war,[11] Lloyd's Register shows that she remained under the German flag under her original name.[12] Schürbek was scrapped in 1948–49.[11]
