During the Korean War, "Begor" served two tours. The first tour, 7 December 1950 through September 1951, included participation in the Hŭngnam Evacuation from 9 through 24 December, and the landing of Underwater Demolition Teams and British Commandos behind enemy lines for reconnaissance and demolition missions. On 7 April 1951, as part of Special Task Force 74, "Begor" along with destroyers , and , landing ship dock and heavy cruiser , helped to carry out raids on rail lines and tunnels utilizing 250 commandos of the 41 (Independent) Commando, Royal Marines. These highly successful and destructive raids slowed the enemy's resupply efforts, forcing the Communists to attempt to repair or rebuild the rail facilities by night while hiding the work crews and locomotives in tunnels by day. The second tour, from 14 November 1952 through 12 August 1953, consisted of patrol and UDT operations, as well as participation in the post-Armistice prisoner of war exchange.
