HMS Attacker (D02) was a notable escort carrier that served prominently during the Second World War, originally built as an American merchantman and later converted into a military vessel under the Lend-Lease agreement. The ship was constructed by the Western Pipe and Steel Company of San Francisco, laid down on 17 April 1941 as Steel Artisan, and launched on 27 September 1941. After her conversion to an escort carrier, she was renamed USS Barnes (CVE-7) and commissioned into the US Navy on 30 September 1942. On the same day, she was decommissioned and transferred to the Royal Navy, where she was commissioned as HMS Attacker under Captain Shirley-Rollison. HMS Attacker measured 496 feet (151 meters) in length, with a beam of 69 feet 6 inches (21.18 meters) and a draught of 24 feet (7.3 meters). She displaced approximately 14,400 long tons (14,600 tonnes) at full load. Propelled by two boilers feeding a steam turbine, she generated 8,500 shaft horsepower, allowing her to reach a top speed of 18 knots (33 km/h). Her flight deck spanned 450 feet by 120 feet (137 m × 37 m), equipped with nine arrestor wires, two aircraft lifts, and a hangar capable of housing up to 24 aircraft, including fighters such as Seafires, Martlets, Corsairs, and Avengers for various combat roles. Her armament was primarily anti-aircraft, with two 4-inch dual-purpose guns, eight 40mm Bofors guns, and numerous 20mm Oerlikon cannons. The vessel’s design supported anti-submarine warfare with aircraft like Swordfish and Avengers, equipped with torpedoes, depth charges, and bombs. She also played a logistical role, providing oil and provisions to escorting destroyers on the move. HMS Attacker’s service was extensive, initially operating in the Atlantic as a convoy escort, then participating in Mediterranean operations such as the landings at Salerno and subsequent campaigns. She was involved in multiple operations, including support for the invasion of Southern France and air cover for various convoys. After a torpedo attack in June 1944 caused damage, she continued operations, notably participating in the invasion of Southern France (Operation Dragoon) and operations in the Aegean Sea. Later, she was transferred to the Pacific theater, where she was involved in operations against Japanese shipping and airfields, including witnessing the Japanese surrender of Penang in August 1945. Following the war, she was returned to the US Navy, struck from the naval register in 1946, and sold into merchant service. Renamed Castel Forte and later Fairsky, she served as a migrant and cruise ship until her final years, when she was damaged by fire and scrapped in 1980. HMS Attacker’s varied career highlights her significance as a versatile escort carrier integral to Allied naval operations during World War II.
