HMS Kempenfelt was a Marksman-class flotilla leader built for the British Royal Navy during World War I. Constructed by Cammell Laird at their Birkenhead shipyard, her keel was laid on October 2, 1914, and she was launched on May 1, 1915. The vessel was completed by August 20, 1915. She measured approximately 324 feet 10 inches (99.01 meters) in overall length, with a waterline length of 324 feet (99 meters), and a beam of 31 feet 9 inches (9.68 meters). Her draft was 12 feet (3.66 meters), and her design displacement was around 1,440 long tons (1,460 metric tons), with full load displacement reaching 1,700 long tons (1,700 metric tons). HMS Kempenfelt was powered by three Brown-Curtis steam turbines fed by four Yarrow boilers, rated at 36,000 shaft horsepower, which enabled her to reach speeds of up to 34 knots (63 km/h). She could carry up to 515 tons of oil fuel, providing a range of approximately 4,290 nautical miles at 15 knots. Her main armament consisted of four QF 4-inch (102 mm) Mk IV guns arranged along the centerline, with two positioned between the funnels. The anti-aircraft defense was initially planned to include two 1-pounder pom-poms, but these were replaced by two 2-pounder pom-poms during construction. She was also equipped with two twin 21-inch (533 mm) torpedo tubes. Kempenfelt’s service history includes her joining the 11th Destroyer Flotilla at Scapa Flow upon commissioning, where she served as a flotilla leader. Notably, she reported sighting a submarine periscope during sea trials in August 1915. During the Battle of Jutland in 1916, she participated as part of the 11th Flotilla and survived without damage. She was involved in rescue operations following the sinking of the battleship King Edward VII in January 1916. Later, she served with the Dover Patrol from September 1917 until April 1918, before rejoining her previous flotilla. By March 1919, she was placed in reserve at Portsmouth. Ultimately, HMS Kempenfelt was sold for scrap in 1921 and broken up at Ward’s Morecambe yard. This vessel exemplifies the multi-role capabilities of early 20th-century destroyer leaders, combining speed, firepower, and versatility, and served an active role in the Royal Navy’s wartime operations.
