Шаблон:Infobox ship imageШаблон:Infobox ship careerШаблон:Infobox ship characteristicsHMS Sea Nymph was a S-class submarine of the third batch built for the Royal Navy during World War II. Completed in July 1942, she spent the majority of her career patrolling the waters off Norway in the North Sea, then was sent to the Pacific but was forced back due to technical problems.
After three uneventful patrols in the North Sea, the boat conducted one patrol in the Bay of Biscay, attacking two surfaced German U-boats with torpedoes, but missed. The submarine then participated in Operation Source, an attempt to sink German battleships in Norway threatening allied Arctic convoys. Sea Nymph was assigned to tow the midget submarine X8 to off the fjord where the Шаблон:Ship was anchored. While at sea, X8 was scuttled due to technical issues, and the mission was cancelled. The submarine was then tasked with transporting British agents to a fishing vessel off Norway. In her next two patrols, the boat fired torpedoes on three German merchant ships, but missed every attack. In March 1944, Sea Nymph was sent to the United States for a refit; she returned in October, then after an uneventful patrol, she had her battery changed. With Nazi Germany close to defeat, the submarine was ordered to the Pacific, where war with the Japanese was also ongoing. She had to turn back and have her battery replaced again after encountering problems; after arriving in the Philippines, on 13 July Sea Nymph caught on fire and was damaged beyond the repair capabilities of local shipyards. She was sent back to Great Britain, but as the war with Japan ended, she was not repaired but placed in reserve. Sea Nymph was scrapped in Troon, Scotland in June 1948.
Design and description
The S-class submarines were designed to patrol the restricted waters of the North Sea and the Mediterranean Sea. The third batch was slightly enlarged and improved over the preceding second batch of the S-class. The submarines had a length of Шаблон:Convert overall, a beam of Шаблон:Convert and a draught of Шаблон:Convert. They displaced Шаблон:Convert on the surface and Шаблон:Convert submerged.[1] The S-class submarines had a crew of 48 officers and ratings. They had a diving depth of Шаблон:Convert.[2]
For surface running, the boats were powered by two Шаблон:Convert diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Шаблон:Convert electric motor. They could reach Шаблон:Convert on the surface and Шаблон:Convert underwater.[3] On the surface, the third batch boats had a range of Шаблон:Convert at Шаблон:Convert and Шаблон:Convert at Шаблон:Convert submerged.[2]
The boats were armed with seven 21 inch (533 mm) torpedo tubes. A half-dozen of these were in the bow and there was one external tube in the stern. They carried six reload torpedoes for the bow tubes for a grand total of thirteen torpedoes. Twelve mines could be carried in lieu of the internally stowed torpedoes. They were also armed with a 3-inch (76 mm) deck gun.[4] It is uncertain if Sea Nymph was completed with a [[Oerlikon 20 mm cannon|Шаблон:Convert Oerlikon]] light AA gun or had one added later. The third-batch S-class boats were fitted with either a Type 129AR or 138 ASDIC system and a Type 291 or 291W early-warning radar.[5]
Construction and career
Sea Nymph was a third-batch S-class submarine and was ordered by the British Admiralty on 2 September 1940. She was laid down in the Cammell Laird shipyard in Birkenhead as P 73 on 6 May 1941 and was launched on 29 July 1942.[6] On 1 November 1942, P 73, under the command of Lieutenant Geoffrey D. N. Milner, sailed to Holy Loch, where she was commissioned two days later as HMS Sea Nymph.[6][7] The submarine was named after mythical sea creatures, Nereids; she was the second ship with this name.[8]
Northern patrols
After going through training exercises off Scapa Flow and Holy Loch, Sea Nymph set sail on 16 December 1942 for an anti-submarine patrol off Norway. The patrol was uneventful, and the boat returned to port on 2 January 1943. On 15 February 1943, Sea Nymph departed Lerwick for another war patrol in the North Sea, but returned on 11 March having sighted no targets. From 20 March to 9 April, the boat conducted another patrol in the same area, but was again unsuccessful.[7]
After torpedo and gunnery exercises of the River Clyde area, the boat commenced another patrol in the Bay of Biscay, west of France on 28 June. On 13 July, she sighted two German submarines, U-592 and U-669, and fired a full spread of six torpedoes at them, but missed. The boat returned to port of 22 July. From 3 to 20 August, Sea Nymph conducted another uneventful war patrol in the Bay of Biscay.[7]
Operation Source
On 31 August 1943, Sea Nymph conducted training at Port HHZ, Scotland with Шаблон:Sclass2 midget submarines in preparation for Operation Source, an attack on the German battleships in Norway using midget submarines. On 11 September 1943, the boat departed port towing the X-class submarine X8 to her target, the Шаблон:Ship.[9][10] An auxiliary crew was on board during the passage, which was meant to switch with the operational crew near the target. On 15 September, Sea Nymph lost her tow with X8. After one day of searching, X8 was found and taken under tow again. Two days later however, the midget submarine was found to be incapable of submerging due to technical issues and was scuttled. Sea Nymph returned to Lerwick on 8 October.[10][7]
Arctic patrols
After an uneventful patrol in the Arctic from 15 November to 7 December 1943, Sea Nymph was ordered to transport British agents and equipment from Shetland to off Norway, where they would be transferred to a local fishing vessel. She landed the agents successfully on 7 January 1944, then returned to port on the 10th. On the 16th, she departed again for another war patrol off Norway. After unsuccessfully attacking a German merchant ship and its escort on the 25th, she returned to Lerwick on the 30th.[7]
From 2 to 21 February, the boat underwent maintenance, then left for another patrol in northern waters. On 1 March, she unsuccessfully fired four torpedoes at the German merchant ship Jupiter and her two escorts. Two days later she attacked the German merchant ship Levante, but again missed with all four torpedoes. The submarine returned to Lerwick on 8 March.[7]
Later career
On 25 March 1944, Sea Nymph departed Great Britain for the US, where she was due to refit at the Philadelphia Naval Shipyard. After a stop at Argentia, then Halifax, Nova Scotia, the boat underwent her refit between 19 April and 16 September. On 11 October, she returned to Holy Loch and underwent additional training, then the submarine went on another patrol from 6 to 17 January 1945 in the Norwegian Sea in search of German U-boats. After having her battery changed during February in Elderslie, Scotland, Sea Nymph was reassigned to the Pacific theater of operations, arriving at Gibraltar on 22 March. However, upon reaching Aden, the boat developed problems with her battery and was sent back to Port Said in Egypt for repairs. From 2 to 16 May, she had her battery replaced, then she sailed for Subic Bay, Philippines, passing through Trincomalee and arriving on 28 June.[7]
While alongside the submarine depot ship HMS Maidstone on 13 July, Sea Nymph caught on fire. A damage assessment concluded that she had to be sent home for repairs, as local dockyards could not perform the task. After temporary repairs allowing her to get underway, she departed Subic Bay and made the trip back to Great Britain, arriving on 30 October 1945. During her return, the war with Japan had ended, and Sea Nymph was not repaired but placed in reserve. In June 1948, the boat was sold for scrap metal at Troon, Scotland.[7]
