HMS Zealous was a Z-class destroyer of the Royal Navy, constructed in 1944 by Cammell Laird. As part of the War Emergency Programme, the Z-class ships were designed for versatility and mass production, featuring a length of approximately 362 feet 9 inches overall, a beam of 35 feet 8 inches, and a full load displacement of about 2,530 long tons. Powered by two Parsons geared steam turbines supplied by Admiralty water-tube boilers, Zealous could reach speeds up to 36 knots and had an operational range of nearly 4,700 nautical miles at 20 knots. Her armament consisted of four 4.5-inch guns, a twin Hazemayer Bofors 40 mm mount, six Oerlikon 20 mm cannons (later replaced by four 2-pounder "pom-poms"), two quadruple torpedo mounts for 21-inch torpedoes, and a variety of depth charges for anti-submarine warfare. The crew comprised approximately 179 officers and ratings. Commissioned in October 1944, Zealous participated in numerous operations in the North Sea and off the Norwegian coast during World War II, including escorting Arctic convoys and engaging in anti-shipping strikes. She was involved in significant wartime activities such as Operation Urbane and the escort of Arctic convoys JW 64 and JW 66, rescuing Norwegian civilians behind enemy lines, and participating in the liberation of Copenhagen. After the war, she served in the Home Fleet, undertaking occupation duties and reserve status until her refit periods in the late 1940s and early 1950s. In 1956, Zealous was sold to Israel and renamed INS Eilat, becoming a key vessel in the Israeli Navy. She saw action during the Suez Crisis, attacking Egyptian ships, and later participated in the 1967 Six-Day War. During that conflict, Eilat was famously sunk on 21 October 1967 by missiles launched from Egyptian missile boats, marking the first wartime sinking of a vessel by missile boats, which signaled a pivotal shift in naval warfare. Her loss had profound strategic implications worldwide, influencing the development of fast, missile-equipped boats. The vessel's torpedo tubes are preserved at the Clandestine Immigration and Naval Museum in Haifa, commemorating her distinguished service and historic sinking.
