The French aircraft carrier Arromanches (R95), originally the HMS Colossus (15) of the Royal Navy, was a Colossus-class light carrier constructed during World War II. Laid down at Vickers-Armstrongs' High Walker shipyard on June 1, 1942, she was launched on September 30, 1943, and commissioned into the Royal Navy on December 1, 1944. She was formally handed over to the Royal Navy in December 1944 and served primarily as an aircraft transport and repatriation vessel with no wartime combat during WWII. Her design prioritized cost-effectiveness, built to mercantile standards with no armor, light armament, and a maximum speed of 25 knots (46 km/h). She measured approximately 211 meters in length with a flight deck 24.5 meters wide, featuring a bow-mounted catapult, two aircraft lifts, and a sizable hangar capable of housing around 13 TBMs or 15 F4Us in her later configurations. Her initial armament included twenty-four 2-pounder guns, thirty-two Oerlikon 20 mm cannons (later replaced by Bofors 40 mm guns), and four Vickers 3-pounder guns. During her service with the Royal Navy, she operated a diverse air group, including fighters such as Vought F4U-7 Corsair, Grumman F6F-5 Hellcat, Supermarine Seafire, and torpedo bombers like the Douglas SBD-5 Dauntless. After being loaned to France in 1946 and officially purchased in 1951, she was renamed Arromanches and participated in the First Indochina War and the Suez Crisis. She was notably reconstructed in 1957-58 with a new angled flight deck and ASW modifications, enabling her to operate aircraft like the Breguet Alizé. In 1968, Arromanches was converted into a helicopter carrier, accommodating up to 24 helicopters, including Sikorsky models and Piasecki H-21. She served until her decommissioning on January 22, 1974, and was dismantled in Toulon in 1978. Her service history reflects a versatile vessel that transitioned from WWII transport and combat support to a key asset in French military operations during the Cold War era, emphasizing her maritime significance as a flexible and durable carrier.
