HMS Emperor (D98) was a Royal Navy escort carrier, originally built as the USS Pybus (CVE-34), a United States Navy Bogue-class vessel. Laid down on June 23, 1942, by the Seattle-Tacoma Shipbuilding Corporation in Washington, she was launched on October 7, 1942, and commissioned into the US Navy on May 31, 1943. The ship measured approximately 492 feet 3 inches (150 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). She was powered by a steam turbine driving a single shaft, producing 9,350 shaft horsepower, which enabled a maximum speed of 16.5 knots. Designed as a larger escort carrier with a crew complement of around 646, her flight deck measured about 260 by 62 feet, equipped with a small combined bridge–flight control on the starboard side, two aircraft lifts, one catapult, and nine arrestor wires. Her hangar below the flight deck extended 79.2 by 18.9 feet, supporting a maximum aircraft capacity of 24 planes, which could include fighters such as F6F Hellcats and Corsairs, as well as anti-submarine aircraft like Swordfish or Avenger torpedo bombers. Her armament comprised dual-purpose 4-inch or 5-inch guns, along with multiple Bofors 40mm and Oerlikon 20mm anti-aircraft guns. Transferred from the US Navy under the Lend-Lease program, she was commissioned into the Royal Navy as HMS Emperor on May 31, 1943. During her service, she participated in key operations including providing fighter cover against the German battleship Tirpitz, supporting the D-Day landings, and aiding the invasion of Southern France. Later, she was transferred to the Indian Ocean fleet, supporting landings in Burma and engaging in the naval hunt for the Japanese cruiser Haguro. After World War II, HMS Emperor was involved in the re-occupation of Malaya before returning to the US in December 1945, carrying 800 Squadron personnel. She was decommissioned and struck from the Naval Vessel Register in early 1946, eventually being sold for scrap in May of that year. Her service highlights her role as a versatile and significant component of Allied naval operations during the war.
