There were eight Attacker-class escort carriers in service with the Royal Navy during the Second World War. They were built between 1941 and 1942 by the Ingalls Shipbuilding and Western Pipe & Steel shipyards in the United States, both building four ships each.^[1]

The vessels had a complement of 646 officers and ratings and crew accommodation was different from the normal Royal Navy's arrangements. The separate messes no longer had to prepare their own food, as everything was cooked in the galley and served cafeteria style in a central dining area. They were also equipped with a modern laundry and a barber shop. The traditional hammocks were replaced by three tier bunk beds, eighteen to a cabin which were hinged and could be tied up to provide extra space when not in use.^[2]

The ships dimensions were; an overall length of 492.25 feet (150.04 m), a beam of 69.5 feet (21.2 m) and a height of 23.25 ft (7.09 m). They had a displacement of 11,420 long tons (11,600 t) at deep load.^[3] Propulsion was provided by four diesel engines connected to one shaft giving 8,500 brake horsepower (6,300 kW), which could propel the ship at 17 knots (31 km/h; 20 mph).^[4]

Aircraft facilities were a small combined bridge–flight control on the starboard side above the 450-by-120-foot (137 m × 37 m) flight deck,^[5] two aircraft lifts 42 by 34 feet (13 by 10 m), and nine arrestor wires. Aircraft could be housed in the 260-by-62-foot (79 by 19 m) hangar below the flight deck.^[3] Armament comprised two 4"/50, 5"/38 or 5"/51 in single mounts, eight 40 mm anti-aircraft guns in twin mounts and twenty-one 20 mm anti-aircraft cannon in single or twin mounts.^[3] The ships had the capacity for up to eighteen aircraft which could be a mixture of Grumman Martlet, Hawker Sea Hurricane, Vought F4U Corsair fighters and Fairey Swordfish or Grumman Avenger anti-submarine aircraft.^[3]

Pursuer served in the Home Fleet during World War II, primarily on convoy escort duty. However, on 3 April 1944, she provided fighter support for an air strike on the German battleship Tirpitz in Altenfjord, Norway. On 26 April 1944 Grumman Wildcats of 882 Naval Air Squadron took part in the successful attack on a German convoy off Bodo, northern Norway. It consisted of four medium-sized supply ships and five escort craft. All four supply vessels and one of the escorts were hit with bombs and three of the supply ships were left on fire, the largest having run aground. While this attack was in progress other naval aircraft penetrated Bodo Harbour, where one large supply ship was hit by bombs and set on fire amidships. Pursuer suffered storm damage during this operation and repairs took a month to complete.

She served as an anti-submarine warfare vessel at the Battle of Normandy and in August and September 1944 she was part of a British carrier group providing air cover for the landings in southern France. The carrier was returned to United States custody on 12 February 1946, struck from the Navy Register on 28 March 1946, and sold for scrapping on 14 May that year to the Patapsco Steel Scrap Co., Bethlehem, Pennsylvania.
