HMS Ben-my-Chree was a packet steamer and a Royal Navy (RN) seaplane carrier of the First World War. She was originally built in 1907 by Vickers for the Isle of Man Steam Packet Company and was intended for use on the England–Isle of Man route. She was the third vessel to bear her name. To this day Ben-my-Chree holds the crossing speed record from Liverpool to Douglas for a steamship at under three hours.
HMS Engadine was a seaplane tender which served in the Royal Navy during the First World War. Converted from the cross-Channel packet ship SS Engadine, she was initially fitted with temporary hangars for three seaplanes for aerial reconnaissance and bombing missions in the North Sea. She participated in the Cuxhaven Raid in late 1914 before she began a more thorough conversion in 1915 that increased her capacity to four aircraft. Engadine was transferred to the Battle Cruiser Fleet in late 1915 and participated in the Battle of Jutland in 1916 when one of her aircraft flew the first heavier-than-air reconnaissance mission during a naval battle. She was transferred to the Mediterranean in 1918.
The Implacable-class aircraft carrier consisted of two aircraft carriers built for the Royal Navy during World War II. Derived from the design of the Illustrious class, they were faster and carried more aircraft than the older ships. They were initially assigned to the Home Fleet when completed in 1944 and attacked targets in Norway as well as the German battleship Tirpitz. Subsequently, they were assigned to the British Pacific Fleet (BPF).
HMS Implacable was the name ship of her class of two aircraft carriers built for the Royal Navy during World War II. Upon completion in 1944, she was initially assigned to the Home Fleet and attacked targets in Norway for the rest of the year. She was subsequently assigned to the British Pacific Fleet (BPF) where she attacked the Japanese naval base at Truk and targets in the Japanese Home Islands in 1945. The ship was used to repatriate liberated Allied prisoners of war (PoWs) and soldiers after the Japanese surrender, for the rest of the year. Implacable returned home in 1946 and became the Home Fleet's deck-landing training carrier, a role that lasted until 1950. She briefly served as flagship of the Home Fleet in 1950. During this time she participated in many exercises and made a number of port visits in Western Europe. She was placed in reserve in 1950 and converted into a training ship in 1952, and served as flagship of the Home Fleet Training Squadron. The ship was considered for a major modernisation in 1951–1952, but this was rejected as too expensive and time-consuming. Implacable was decommissioned in 1954 and sold for scrap the following year.
The Courageous class, sometimes called the Glorious class, was the first multi-ship class of aircraft carriers to serve with the Royal Navy. The three ships—Furious, Courageous and Glorious—were originally laid down as Courageous-class battlecruisers as part of the Baltic Project during the First World War. While very fast, their minimal armour and few guns limited their long-term utility in the post-war Royal Navy, and they were laid up after the war. They were considered capital ships by the terms of the 1922 Washington Naval Treaty and were included in the total amount of tonnage allowed to the Royal Navy. Rather than scrap them, the Navy decided to convert them to aircraft carriers as permitted under the Treaty.
HMS Courageous was the lead ship of her class of three battlecruisers built for the Royal Navy in the First World War. Designed to support the Baltic Project championed by First Sea Lord John Fisher, the ship was very lightly armoured and armed with only a few heavy guns. Courageous was completed in late 1916 and spent the war patrolling the North Sea. She participated in the Second Battle of Heligoland Bight in November 1917 and was present when the German High Seas Fleet surrendered a year later.
The Courageous class consisted of three battlecruisers known as "large light cruisers" built for the Royal Navy during the First World War. The class was nominally designed to support the Baltic Project, a plan by Admiral of the Fleet Lord Fisher that was intended to land troops on the German Baltic Coast. Ships of this class were fast but very lightly armoured, with only a few heavy guns. They were given a shallow draught, in part to allow them to operate in the shallow waters of the Baltic but also reflecting experience gained earlier in the war. To maximize their speed, the Courageous-class battlecruisers were the first capital ships of the Royal Navy to use geared steam turbines and small-tube boilers.
HMS Furious was a modified Courageous-class battlecruiser built for the Royal Navy (RN) during the First World War. Designed to support the Baltic Project championed by the First Sea Lord, Lord Fisher, the ship was very lightly armoured and designed with a main battery of only two 18-inch guns. Furious was modified as an aircraft carrier while under construction. Her forward turret was removed and a flight deck was added in its place, such that aircraft had to manoeuvre around the superstructure to land. Later in the war, the ship had her rear turret removed and a second flight deck installed aft of the superstructure, but this was less than satisfactory due to air turbulence. Furious was briefly laid up after the war before she was reconstructed with a full-length flight deck in the early 1920s.
The Hawkins class consisted of five heavy cruisers built for the Royal Navy during the First World War, although none of them saw service during the war. The first ship to be completed, HMS Vindictive, was renamed from HMS Cavendish and converted into an aircraft carrier while under construction. All ships were named after Elizabethan sea captains. The three ships remaining as cruisers in 1939 served in the Second World War, with Effingham being an early war loss through wreck; Raleigh had been lost in a similar shipwreck on uncharted rocks in 1922. Vindictive, though no longer a cruiser, also served throughout the War. This class formed the basis for the definition of the maximum cruiser type under the Washington Naval Treaty of 1922.
HMS Vindictive was a warship built during the First World War for the Royal Navy (RN). Originally designed as a Hawkins-class heavy cruiser and laid down under the name Cavendish, she was converted into an aircraft carrier while still being built. Renamed in 1918, she was completed a few weeks before the end of the war and saw no active service with the Grand Fleet. The following year she participated in the British campaign in the Baltic against the Bolsheviks, during which her aircraft made numerous attacks against the naval base at Kronstadt. Vindictive returned home at the end of the year and was placed in reserve for several years before her flight decks were removed and she was reconverted back into a cruiser. The ship retained her aircraft hangar and conducted trials with an aircraft catapult before she was sent to the China Station in 1926. A year after her return in 1928, she was again placed in reserve.
The Malta-class aircraft carrier was a British large aircraft carrier design of World War II. Four ships were ordered in 1943 for the Royal Navy, but changing tactical concepts, based on American experience in the Pacific War, caused repeated changes to the design, which was not completed before the end of the war. All four ships were cancelled in 1945 before they were laid down.
HMS Ark Royal was the first ship designed and built as a seaplane carrier. She was purchased by the Royal Navy in 1914 shortly after her keel had been laid and the ship was only in frames; this allowed the ship's design to be modified almost totally to accommodate seaplanes. During the First World War, Ark Royal participated in the Gallipoli Campaign in early 1915, with her aircraft conducting aerial reconnaissance and observation missions. Her aircraft later supported British troops on the Macedonian Front in 1916, before she returned to the Dardanelles to act as a depot ship for all the seaplanes operating in the area. In January 1918, several of her aircraft unsuccessfully attacked the German battlecruiser SMS Goeben when she sortied from the Dardanelles to attack Allied ships in the area. The ship left the area later in the year to support seaplanes conducting anti-submarine patrols over the southern Aegean Sea.
HMS Hermes was a Highflyer-class protected cruiser built for the Royal Navy in the 1890s. She spent much of her early career as flagship for various foreign stations before returning home in 1913 to be assigned to the reserve Third Fleet. The ship was modified later that year as the first experimental seaplane carrier in the Royal Navy. In that year's annual fleet manoeuvers, she was used to evaluate how aircraft could cooperate with the fleet and if aircraft could be operated successfully at sea for an extended time. The trials were a success and Hermes was paid off in December at their conclusion. She was recommissioned at the beginning of World War I in August 1914 for service as an aircraft ferry and depot ship for the Royal Naval Air Service. She was torpedoed and sunk by a German submarine in the Straits of Dover that October, with the loss of 21 lives.
HMS Riviera was a seaplane tender which served in the Royal Navy (RN) during the First and Second World Wars. Converted from the cross-Channel packet ship SS Riviera, she was initially fitted with temporary hangars for three seaplanes for aerial reconnaissance and bombing missions in the North Sea. She participated in the unsuccessful Cuxhaven Raid in late 1914 before she began a more thorough conversion in 1915 that increased her capacity to four aircraft. Riviera and her aircraft then spent several years spotting for British warship bombarding the Belgian coast and making unsuccessful attacks on targets in Germany. She was transferred to the Mediterranean in 1918 and returned to her owners the following year.
HMS Campania was a seaplane tender and aircraft carrier, converted from an elderly ocean liner by the Royal Navy early in the First World War. After her conversion was completed in mid-1915 the ship spent her time conducting trials and exercises with the Grand Fleet. These revealed the need for a longer flight deck to allow larger aircraft to take off, and she was modified accordingly. Campania missed the Battle of Jutland in May 1916, but made a number of patrols with elements of the Grand Fleet. She never saw combat and was soon relegated to a training role because of her elderly machinery. In November 1918 Campania was anchored with the capital ships of the Grand Fleet when a sudden storm caused her anchor to drag. With no second anchor being laid, she hit several of the ships and the collisions punctured her hull; she slowly sank, with no loss of life.
The Highflyer-class cruisers were a group of three second-class protected cruisers built for the Royal Navy in the late 1890s.
HMS Conquest was a C-class light cruiser of the Royal Navy that saw service during World War I. She was part of the Caroline group of the C class.
HMS Empress was a seaplane carrier of the Royal Navy (RN) that served during the First World War. Converted from the Cross-Channel packet ship Empress, the ship's aircraft conducted aerial reconnaissance, observation and bombing missions in the North Sea and Eastern Mediterranean. During the last year of the war, she conducted anti-submarine patrols in the Mediterranean. Empress was returned to her owners in 1919 and was then sold to a French company in 1923. She was scrapped in 1933.
HMS Vindex was a Royal Navy seaplane carrier during the First World War, converted from the fast passenger ship SS Viking. The ship spent the bulk of her career operating the North Sea, where she twice unsuccessfully attacked the German Zeppelin base at Tondern and conducted anti-Zeppelin patrols. One of her Bristol Scout aircraft made the first take-off from an aircraft carrier in late 1915. Another made the first interception of an airship by a carrier-based aircraft on 2 August 1916, when it unsuccessfully attacked the Zeppelin LZ 53. Vindex was transferred to the Mediterranean in 1918 and was sold back to her original owners in 1920. She was requisitioned again in 1939 and served through the Second World War as a troopship under a different name. After the end of the war, the ship was returned to her owners and was sold for scrapping in 1954.
HMS Nairana was a passenger ferry that was requisitioned by the Royal Navy (RN) as a seaplane carrier in 1917. She was laid down in Scotland in 1914 as TSS Nairana for the Australian shipping line Huddart Parker, but construction was suspended after the outbreak of the First World War. Following resumption of work, the ship was launched in 1915, and converted to operate wheeled aircraft from her forward flying-off deck, as well as floatplanes that were lowered into the water. She saw service during the war with the Grand Fleet, and in 1918–19 supported the British intervention in the Russian Civil War.
