HMS Archer was a Long Island-class escort aircraft carrier originally built as the American cargo ship Mormacland in 1939–1940. She measured approximately 492 feet in overall length, with a beam of about 66 feet and a height of 23 feet. Displacing around 8,200 long tons at normal load, she was powered by four Busch-Sulzer diesel engines producing 8,500 brake horsepower, enabling a top speed of 16.5 knots. Her propulsion system consisted of four diesel engines driving a single shaft, a notable feature among her sister ships. She was converted from her original merchant configuration into an escort carrier at Newport News Shipbuilding & Drydock Co., with her conversion completed by November 1941. The ship retained her original bridge, extended at the sides for better visibility, and was equipped with a flight deck approximately 410 feet long constructed of wood on a truss frame. Her aircraft facilities included one aircraft lift measuring 43 by 34 feet, a catapult, and nine arrestor wires. She could carry up to fifteen aircraft, comprising fighters like Martlets or Sea Hurricanes, and anti-submarine aircraft such as Swordfish or Avengers. Her armament included three single 4-inch dual-purpose guns and fifteen 20 mm cannons. Commissioned into the Royal Navy on 17 November 1941, HMS Archer served as a vital escort carrier during World War II, participating in convoy support, anti-submarine warfare, and aircraft ferry missions. She was notably involved in sinking U-752 with rockets in May 1943, marking the first U-boat destruction by aircraft operating from an escort carrier with rockets. Throughout her service, she experienced persistent mechanical issues, especially with her engines and steering gear, which led to multiple repairs and refits, including lengthening her flight deck. Decommissioned from front-line service in late 1943 due to extensive defects, she was repurposed as a stores ship and accommodation vessel before being transferred to the Ministry of War Transport and renamed Empire Lagan in 1945. Post-war, she returned to U.S. control as USS Archer and was eventually sold into merchant service, becoming the passenger ship Anna Salén, primarily transporting emigrants to Australia and Canada in the late 1940s and early 1950s. Later renamed Tasmania and Union Reliance, she continued cargo and passenger routes until her collision and fire in 1961, after which she was scrapped. Her varied service history highlights her maritime significance as a versatile vessel transitioning from wartime escort duties to civilian merchant operations.
