HMS Striker (D12) was an Attacker-class escort aircraft carrier constructed in the United States during World War II. Laid down as MC hull 198 by the Western Pipe and Steel Company in San Francisco on 15 December 1941, the vessel was originally designated as Prince William (CVE-19) and underwent a series of redesignations, including AVG-19, ACV-19, and CVE-19. The ship was transferred to the Royal Navy under the Lend-Lease agreement, launched on 7 May 1942, and commissioned into service as HMS Striker on 18 May 1943. The vessel measured approximately 492 feet in length, with a beam of 69.5 feet and a height of 23.25 feet. Displacing around 11,420 long tons at deep load, HMS Striker was powered by four diesel engines connected to a single shaft, capable of generating 8,500 brake horsepower, which allowed for a maximum speed of 17 knots. The ship's flight deck was 450 by 120 feet, with two aircraft lifts, nine arrestor wires, and a hangar below accommodating up to 18 aircraft. Its armament included dual 4"/50, 5"/38 or 5"/51 caliber guns, eight 40mm anti-aircraft guns in twin mounts, and twenty-one 20mm anti-aircraft cannons, providing substantial defensive firepower. The aircraft complement could include fighters such as Grumman Martlet, Hawker Sea Hurricane, and Vought F4U Corsair, as well as anti-submarine aircraft like the Fairey Swordfish or Grumman Avenger. Throughout World War II, HMS Striker served notably in the Far East and Pacific theaters. During late 1944, she ferried Mosquito aircraft from Scotland to Australia, supporting operations in the Far East. From March to August 1945, she served as the flagship of the British Pacific Fleet's 30th Aircraft Carrier Squadron. After the war, she was returned to the US Navy on 12 February 1946, struck from the Naval Register shortly after, and sold for scrap in 1948. HMS Striker exemplifies the vital role of escort carriers in providing versatile air support during wartime, with a design tailored for both fleet defense and maritime escort duties.
