HMS Trump
HMS Trump
HMS Trump (pennant number P333) was a British submarine of the third group of the T class. She was built by Vickers-Armstrongs, Barrow, and launched on 25 March 1944. So far she has been the only ship of the Royal Navy (RN) to bear the name Trump. She spent the majority of her life attached to the 4th Submarine Squadron) based in Australia. She was kept in service following the war and was refitted for greater underwater performance, and was the final RN submarine to be posted in Australia, departing in January 1969. She was sold off and broken up for scrap in August 1971.
Design and description
HMS Trump was one of the group three of T-class submarines. She was part of the second batch of the third group to be ordered, in 1941. She was one of a number of boats which had an all-welded hull which increased diving depth to 350 feet (107 m), an increase of 50 feet (15 m). The torpedo armament was the same as the earlier group two, although by the time group three was coming into service it was realised that external torpedo tubes had major problems and affected the streamlining of the boats; the external tubes were abandoned in the following Amphion class. Due to expected use in tropical climates, boats of group three were equipped with freon blowers in order to deal with the increased temperatures.
World War II
Trump was commissioned in July 1944. After trials and a work-up in the North Sea in mid-October she was sent to Perth in Western Australia. On arrival, she joined the 4th Submarine Squadron), supported by the depot ship HMS Adamant). From Perth, Trump carried out four patrols before the end of the war.
