HMS Empress (D42) was an escort aircraft carrier originally built in 1942-43 as USS Carnegie (CVE-38) for transfer to the United Kingdom during World War II. She was among a class of larger escort carriers with greater aircraft capacity than earlier American-built ships, designed specifically as escort carriers rather than conversions from merchant vessels. The vessel measured approximately 492 feet 3 inches (150.0 meters) in length, with a beam of 69 feet 6 inches (21.2 meters) and a draught of 25 feet 6 inches (7.8 meters). Her propulsion system comprised a steam turbine connected to two boilers and a single shaft, delivering 9,350 brake horsepower, which enabled her to reach speeds of up to 16.5 knots. Her aircraft facilities included a small combined bridge and flight control on the starboard side, two aircraft lifts measuring 43 by 34 feet, a single catapult, and nine arrestor wires for aircraft recovery. The hangar below the flight deck was 260 by 62 feet, providing ample space for storage and maintenance of her aircraft complement. Her armament comprised two dual-purpose guns—either 4"/50, 5"/38, or 5"/51 calibers—along with sixteen 40mm Bofors anti-aircraft guns in twin mounts and twenty 20mm Oerlikon cannons in single mounts, offering defensive protection against aerial threats. Designed to carry a maximum of 24 aircraft—including fighters like the Grumman Martlet, Vought F4U Corsair, or Hawker Sea Hurricane, and anti-submarine aircraft such as the Fairey Swordfish or Grumman Avenger—HMS Empress served notably in the Pacific and Indian Oceans during World War II. A significant event in her service was her participation in Operation Tiderace in September 1945, the reoccupation of Singapore from Japanese control. After the war, she was returned to U.S. custody in January 1946, struck from the naval register in March, and subsequently sold for scrap in June 1946.
