HMS Empress was a seaplane carrier of the Royal Navy that served during the First World War. Originally built as a fast packet ship for the South East and Chatham Railway Co., she measured 323 feet (98.5 meters) in length, with a beam of 41 feet (12.5 meters) and a draught of 15 feet (4.6 meters). She displaced approximately 2,540 long tons (2,580 metric tons) and was rated at 1,694 gross register tons. Powered by three sets of direct-drive steam turbines driving individual propeller shafts, she generated 8,800 shaft horsepower, enabling her to reach a sea trial speed of 22.26 knots, exceeding her designed speed of 18 knots. Her boilers produced enough steam for her propulsion, and she carried 425 tonnes of coal, giving her a range of 1,355 nautical miles at 15 knots. Requisitioned by the Royal Navy in August 1914, Empress was converted at Chatham Dockyard into a seaplane carrier capable of operating three aircraft simultaneously. She was fitted with canvas hangars for one aircraft forward and two aft, with cargo booms to handle the seaplanes. During her service, she operated various types of floatplanes, including Fairey Hamble Baby, Short Admiralty Type 74, Short Type 184, Sopwith Schneider, and Baby floatplanes. Armament included two or three QF 2-pounder guns initially, later replaced by four QF 12-pounder guns and two Vickers QF 3-pounder anti-aircraft guns following a refit in 1915. Her operational history included participation in the Cuxhaven Raid on Zeppelin hangars on Christmas Day 1914, where her aircraft took part in an attack on German airship facilities. She was transferred to Queenstown in 1915 and then moved to the Mediterranean, where she supported reconnaissance and attack missions against Turkish positions in Palestine, the Aegean, and Syria. From 1918, she was assigned anti-submarine duties at Port Said and Gibraltar. After the war, she was returned to her owners in 1919, sold to a French company in 1923, and continued to serve until she sank the British schooner John Gibson in 1926 after a collision. HMS Empress was ultimately scrapped in France in 1933.
