HMS Biter was an Avenger-class escort carrier of the Royal Navy, originally constructed as a merchant ship named Rio-Parana by the Sun Shipbuilding & Drydock Company in Chester, Pennsylvania. Laid down on 28 December 1939 and launched on 18 December 1940, she was delivered on 4 September 1941 before being converted into a military escort carrier at the Atlantic Basin Iron Works in Brooklyn, New York. Commissioned into the Royal Navy on 6 May 1942 under Captain Conolly Abel Smith, HMS Biter served as a vital component of Allied anti-submarine efforts during World War II. The vessel measured 492 feet in length, with a beam of 66 feet 3 inches, and a height of 23 feet 3 inches. She displaced approximately 8,200 long tons at normal load, increasing to 9,000 long tons at deep load. Propulsion was provided by four diesel engines driving a single shaft, producing 8,500 horsepower, which enabled her to reach a speed of 16.5 knots. Her flight deck was 410 feet long, constructed of wood, with a combined bridge and flight control on the starboard side. The ship's aircraft facilities included a single aircraft lift measuring 43 by 34 feet, a catapult, and nine arrestor wires, with capacity for up to fifteen aircraft, including fighters like Sea Hurricanes and Martlets, and torpedo bombers such as Swordfish and Avengers. HMS Biter’s service history was marked by active participation in key operations, including the North Africa landings (Operation Torch), where she provided air cover off Oran. She experienced notable incidents such as a fire on 8 May 1942 during her preparations and operational damage from crashes and enemy aircraft. Her aircraft engaged U-boats and supported convoy escort missions across the Atlantic, frequently conducting anti-submarine patrols with Swordfish and Martlet aircraft. She contributed significantly to the sinking of multiple U-boats, including U-191, U-203, U-456, and U-753, during her patrols and convoy support missions. After her wartime service, HMS Biter was returned to the US Navy in 1945, subsequently lent to the French Navy and renamed Dixmude, where she served with the French fleet until 1949. Following her decommissioning, the vessel was used as an accommodation ship before being sunk as a target during a US Navy exercise in 1966. Her operational history underscores her importance as a versatile escort carrier in the Battle of the Atlantic and her enduring maritime significance.
