HMS Rushen Castle

Design and description

The Castle-class corvette was a stretched version of the preceding , enlarged to improve seakeeping and to accommodate modern weapons. The ships displaced 1010 LT at standard load and 1510 LT at deep load. The ships had an overall length of 252 ft, a beam of 36 ft The engine developed a total of 2880 ihp and gave a speed of 16.5 kn. The Castles carried enough fuel oil to give them a range of 6500 nmi at 15 kn. The ships' complement was 99 officers and ratings.

The Castle-class ships were equipped with a single QF 4 in Mk XVI dual-purpose gun forward, but their primary weapon was their single three-barrel Squid anti-submarine mortar. This was backed up by one depth charge rail and two throwers for 15 depth charges. The ships were fitted with two twin and a pair of single mounts for 20 mm Oerlikon AA guns. Provision was made for a further four single mounts if needed. They were equipped with Type 145Q and Type 147B ASDIC sets to detect submarines by reflections from sound waves beamed into the water. A Type 272 search radar and a HF/DF radio direction finder rounded out the Castles' sensor suite.

Construction and career

Ordered on 6 February 1943, Rushen Castle was laid down at Swan Hunter & Wigham Richardson at their shipyard in Wallsend on 8 April. The ship was launched on 16 July and completed on 24 February 1944. After several weeks of training in Western Approaches Command's Anti-Submarine Training School at Tobermory, Mull, she was assigned to Escort Group B2 on 16 March on the Gibraltar-UK route. Rushen Castle remained on this route despite being transferred to Escort Group B21 in September and then to the Liverpool Escort Group in December. The ship's last convoy reached port on 27 June 1945, even though Germany had surrendered on 8 May. Rushen Castle was then assigned to Plymouth Command for air-sea rescue duties. The ship was refitted from October 1945 to January 1946 and was then reduced to reserve at Devonport.

She received a brief refit from 24 September to 2 October 1947 when the Royal Navy was thinking to offering her to the Royal New Zealand Navy, but that service opted for larger s instead. Rushen Castle was offered to the Air Ministry in 1956 for use as a weather ship, but was not sold until 23 September 1960. Her conversion was completed at Blyth on November 1961 and she was renamed Weather Surveyor. She was sold in July 1977 and converted to a salvage vessel. The ship was departed under tow on 11 May 1982 to be scrapped in Germany.
