HMS Dundas was a Blackwood-class anti-submarine warfare (ASW) frigate of the Royal Navy, representing a class of vessels primarily designed for ASW duties. She was the first of her class to be commissioned, entering service on 9 March 1956. Built by JS White and Co Ltd in Cowes, Dundas had a length of 310 feet (94 meters), a beam of 33 feet (10 meters), and a draught of 15 feet (4.6 meters). Her displacement was 1,180 tonnes when empty and increased to 1,535 tonnes when fully loaded. Powered by a Parsons or English Electric geared steam turbine and two Babcock & Wilcox boilers, Dundas generated 15,000 shaft horsepower, enabling her to reach a top speed of approximately 25 knots (46 km/h). Her armament comprised two Mk.NC 10 Limbo 3-barreled ASW mortars and two 21-inch (533 mm) torpedo tubes in twin mounts, complemented by sonar and radar systems for combat and navigation. Throughout her service, Dundas played a significant role in ASW training and naval exercises. She was part of the 2nd Frigate Squadron, based at Portland, and participated in various Navy Days events, including Portsmouth Navy Days in 1966, 1970, and 1977, the latter as part of the Silver Jubilee Fleet Review at Spithead. In 1968, after a 14-month refit at Gibraltar Dockyard, she was re-commissioned and continued her role in training officers and men in ASW tactics. Notably, Dundas appeared briefly in the 1957 film "The Little Hut" and in a 1964 documentary episode. Her operational career was eventually cut short when a propeller shaft knock was discovered in 1983, leading to her being moved to Chatham Dockyard. Following decommissioning, she was scrapped in Troon in April 1983. Her service highlights the Cold War-era focus of the Royal Navy on anti-submarine capabilities and her role in training and fleet exercises underscore her maritime significance during her operational life.
