HMS Queen Emma was a former civilian passenger liner built in 1939 by De Schelde at Vlissingen, originally named MS Koningin Emma. The ship measured a gross tonnage of 4,135 tons and was capable of carrying up to 1,800 passengers. Her propulsion system consisted of two 2-stroke Sulzer diesel engines, which together produced 12,500 shaft horsepower, enabling her to achieve speeds exceeding 24.5 knots during sea trials—faster than her contractual requirement. The vessel was launched on 14 January 1939, with Queen Wilhelmina herself attending the launch, though she initially experienced difficulty on the slipway. Initially serving as a civilian ferry between Vlissingen and Harwich, MS Koningin Emma’s service was interrupted by the outbreak of World War II. She fled to Britain in May 1940 after the German invasion of the Netherlands, and was subsequently requisitioned by the British Ministry of War Transport. Fitted with degaussing coils for protection against magnetic mines, she was crewed by her original Dutch crew along with a Marine detachment. Renamed HMS Queen Emma, she was converted into a troopship at Harland and Wolff’s Belfast yard, with modifications including the installation of gravity davits to carry landing craft and armament comprising 12-pounder guns, 2-pounders, Hotchkiss 20 mm machine guns, and .303 caliber machine guns. Her wartime service was notable for transporting British Commandos and participating in key operations such as the Lofoten Islands Raid, the Dieppe Raid, and the landings in North Africa, Sicily, and Normandy. She was involved in numerous amphibious assaults, often operating at night, and earned acclaim from Allied commanders. During the Sicilian campaign, she was hit by German fire, which reduced her speed and led to her being downgraded to a troop transport vessel. After the Italian capitulation, she supported the reoccupation of Penang and participated in post-war operations in the Indian Ocean. Decommissioned in 1946, she returned to her original name, MS Koningin Emma, and resumed ferry service between the Hook of Holland and Harwich until her retirement in 1969. Scrapped in Antwerp, her career exemplifies the vital role of converted civilian ships in wartime amphibious operations and post-war transportation.
