Notes |
The Leander class was a four-ship cruiser programme ordered by the Admiralty in 1880. The class comprised HMS Leander, HMS Phaeton, HMS Amphion, and HMS Arethusa.
"A new and better policy of unarmoured construction was inaugurated by the Admiralty of 1874-80. They began by building the two despatch vessels, Mercury and Iris, with a speed not approached up to that date by any in naval service. In the Mercury and the Iris, the speed was obtained by an enormous development of horse-power… The cost per ton was equal to that of the most powerful ironclad, while the fighting power was inconsiderable." [7]
In 1880, the Admiralty Board were divided about next design of cruising ship to lay down. The First Naval Lord, Sir Astley Cooper Key, favoured an enlarged 15 knots (28 km/h) Comus class. Some of the other members of the board preferred an improved Iris class. The First Lord of the Admiralty, William H. Smith, backed the latter. [8] A change of government occurred on 23 April 1880; [9] Lord Northbook replaced W.H. Smith as First Lord, though Astley Cooper Key continued as First Naval Lord. [10] "Lord Northbook's board were deeply impressed with the necessity for developing the construction of vessel of the Leander" type. [7] "The first four ships of a large class laid down for the protection of commerce under Lord Northbrook's board were of the Leander type. The Leanders have a displacement of 3,750 tons. Their speed is 17 knots… Their coal supply is 1016 tons. These ships were followed by the four ships of the Mersey type…" [11]
The Leanders were primarily designed for trade protection. [12] In 1881, it was argued that Britain had fallen behind in cruisers to protect Britain's mercantile marine, which at the time was at least half the world total. "Taking 14 knots as the standard of high speed, we have only 11 swift cruisers, counting the Iris and Mercury despatch vessels among them. Fine vessels they are, and no doubt the Shah and the Raleigh, when they have got on board their new armament, will give a good account—a very good account indeed—of any cruiser in the world that is not an iron-clad. But the world is a large place; and eight or ten vessels cannot be everywhere, and the safety of our commerce imperatively demands that the swift cruisers which we have ready at the outbreak of a war shall be enough to clear the seas of privateers. Much use, as a war goes on, may, no doubt, be made of the armed merchantmen on the Admiralty List; but we must have Royal [Navy] cruisers to begin with, A commencement was made last year by the late Board in the Leander and her two consorts, which, with their partially protected machinery, their great speed, and their excellent guns, will be everything that can be desired for the purpose for which they were devised. The present Board have carried this policy farther. We are pushing on the Leanders, and we have laid down a fourth Leander at Pembroke, to occupy the spare time of the 200 extra men who are working on the iron-clads…" [13]
On 2 December 1884, the Secretary to the Admiralty stated, "The present Board have been gradually developing, and, as I would venture to say, in an effective manner, our resources for the protection of commerce. The late Board of Admiralty laid down an admirable type for the purpose in the Leander class. We have followed in their footsteps by producing the Mersey type, and we now propose to go a step further in the same direction, by laying down vessels of the Mersey class, but protected by a belt in lieu of an armoured deck. The belt will, I think, be approved by my hon. Friend who sits behind me (Sir Edward J. Reed)." [14] These belted cruisers were the Orlando class.
Compared with the Iris class, the designers of the Leander "cut down top hamper and took advantage of the recent advance in gun construction to reduce the weight of, while adding to the efficiency of armaments. The models approved for the new ships were favourable to high speed." [7]
"The armament consists of ten 6-inch breech-loading guns, two Gatling guns, ten Nordenfeld guns, four Gardner guns, and four tubes for launching Whitehead torpedoes. Four of the breech-loaders are fixed on revolving turntables which project beyond the sides of the ship. They are placed on either side of the upper deck at the fore end of the poop and after end of the forecastle. These bow guns can be trained from the cross fire of 4˚ forward to 45˚ abaft the beam, and the after guns from right aft fire to 45˚ before the beam. The remaining 6-inch breech-loading guns which these vessels carry are fitted at broadside ports in the ordinary way. The Nordenfeld guns are fitted in projecting parts of the topsides, and are so arranged as to give great training and great depression, firing into boats alongside. The Whitehead torpedoes are discharged from broadside ports on the lower deck, two forward and two aft." [15]
When Leander was first commissioned in May 1885, her armament was listed as:
The Leanders relied for protection on subdivision, coal bunkers, [12] and a one-and-a-half-inch (40 mm) armoured deck over 165 feet amidships. The armoured deck was just above the normal waterline at the centre, and sloped down at the sides to protect against shells entering at the waterline. [8]
The 1886 edition of The Naval Annual described them as:
"With regard to their steaming capabilities, it may be noted that these cruisers with an authorized complement of coal of 725 tons have room in their bunkers for 1000 tons. [16] They also carry three masts, but are not expected to have much sailing power." [15]
"The Phaëton has been tried in the Solent. At the previous six-hour' full power trial of the Phaëton there was a difficulty experienced in maintaining steam from want of draught in the stokeholds. (Only the Leander of this class has been fitted with fans for forced draught.) The funnels were afterwards raised from 60 ft (18 m) to 68 ft (21 m) (the same height as those of the first-class cruisers), while the space between the firebars was increased. The effect of these changes at the trial was very marked, the engines being provided with an abundance of steam without their being any necessity for resorting to the blast. The trial was intended to have been for six hours, but during the eleventh half-hour, the expansion gear of the starboard engine heated and snapped, and the run was brought to a premature close. As, however the machinery worked without any hitch of any kind, and was developing power largely in excess of the Admiralty contract, it was agreed by the officers superintending the trial to accept the means of the five hours as a sufficient test of performance. These afforded the following data: Steam in the boilers, 85.35 lbs [588.5 kPa]; vacuum, 25.3 in (640 mm) starboard and 24.8 in (630 mm) port; revolutions, 100; mean pressures, starboard, 43.7 and 11 lb. [301 kPa and 76 kPa] and 43 and 11.7 lb. [300 kPa and 81 kPa] port; collective horsepower, 5,574.88 ihp (4,157.19 kW) or nearly 600 horses [450 kW] beyond the contract. The mean speed registered by runs on the measured mile was 18.684 knots (34.603 km/h), which was remarkable, notwithstanding her light draught. The coal consumption did not exceed 2.39 lbs. per unit of power per hour [1.45 kg coal per hour per kiloWatt]." [17]

In the 1888 British annual naval manoeuvres, "the proportion of untrained (2nd Class) stokers which were draughted to several of the ships appears to have been too large." [19] The opinion of the captain of the Arethusa was that the "engine room complement [was] insufficient by 2 engine room artificers, 2 leading stokers, and 23 stokers." [20]
The Navy List gave the following composition of officers for the Leander in December 1885 (order as in the original): [21]

The financial year of completion is taken from the statement of the first cost of each effective ship of the Royal Navy under the year of completion in the Navy Estimates for 1889-90. It provides a different view of when the vessels were completed than the usually quoted reference books. Both the Amphion and Arethusa lay in ordinary reserve until commissioned for the 1887 annual manoeuvres, so the date when the vessels were first commissioned was some time after they were completed.
In March 1882, it was stated that "the Leander, the Arethusa, and the Phaeton will pass out of the hands of the contractors, and will come to our own yards to be completed and fitted with the new 6-inch breech-loader; and the Amphion, at Pembroke, will be pushed forward in the intervals of the iron-clad building." [32] It was stated on 1 August 1882, that "the Amphion is being advanced satisfactorily at Pembroke, while the Leander, Arethusa, and Phaeton are promised to be delivered within the year by the contractor, a promise which was renewed within a few days of the present time." [33] But seven months later, it was "noticed with regret" that the ships of the Leander class (and also some of the gun vessels) that were building by contract had not been completed as they ought to have been. [34] The explanation was that there had been a large increase in the expenditure for wages at the Dockyards, and this had paid for by money voted for the construction of the Leanders. Though the "Admiralty have been desirous that the money should be spent on the object for which it is voted, but that it has been prevented by a delay with the contractor." [35] In May 1883, it was "alleged that one of the reasons for the delay in the construction of the Leander is that the Admiralty have not fully decided upon the smaller arrangements which have to be carried out by the builders." However it was doubted that this was the main reason for delays. [36] By May 1884, it was being "said that the Leander should be completed first; that then a trial of the Leander should be made; and that then it should be ascertained what improvements or alterations ought to be effected in the Arethusa, and the other ships of the same class. It is said that the other two are built and are almost complete..." [37] This course of action was opposed by W.H. Smith who said "the Leander class ought to be rendered complete, according to the arrangements undertaken by the Board of Admiralty, without loss of time." [37] [38] On 15 July 1884, the Secretary to the Admiralty stated that "The Leander herself, we expect, will be completed in December in the Dockyards; but the others of her class will not be completed until she has been tried. Directly we are satisfied with her capabilities the others will be completed. They can be completed in about three months." [39] As of 6 March 1885, "the Leander alone was completed." [40] The Secretary to the Admiralty stated: "In 1885–6 we shall complete... [the remaining] three protected ships of the Leander class...". [41] The veracity of Admiralty statistics on the completion of these vessels was questioned in the ensuing debate in the House of Commons by W.H. Smith. [42] When the Leander was completed in 1885, she was considered one of the three most important unarmoured vessels in the 1885 Evolutionary Squadron. [43]

At between £189,672 and £202,113 each, the Leanders were cheaper than the Iris and Mercury, whose costs to completion were £224,052 and £234,860 respectively. [44] The Merseys, that followed them cost between £202,840 and £217,982 each. [23]
The committee appointed to inquire into all circumstances connected with the 1888 British naval manoeuvres reported as follows:
The First Naval Lord, Admiral Sir Arthur Hood commented on this as follows:
"Leander and her three sisters were very successful and may be seen as the ancestors of most [Royal Navy] cruisers for the rest of the century and beyond. Their general configuration was scaled up to the big First Class cruisers and down to the torpedo cruisers, whilst traces of the protected deck scheme can even be recognised in some sloops." [8]
Protected cruisers, a type of cruising warship of the late 19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers which had in addition a belt of armour along the sides. By the early 20th century, with the advent of increasingly lighter yet stronger armour, even smaller vessels could afford some level of both belt and deck armour. In the place of protected cruisers, armoured cruisers would evolve into heavy cruisers and light cruisers, the latter especially taking-up many of roles originally envisaged for that of protected cruisers.
The Type 22 frigate also known as the Broadsword class was a class of frigates built for the British Royal Navy. Fourteen were built in total, with production divided into three batches.
The County class was a class of British guided missile destroyers, the first such warships built by the Royal Navy. Designed specifically around the Seaslug anti-aircraft missile system, the primary role of these ships was area air defence around the aircraft carrier task force in the nuclear-war environment.
The Leander-class, or Type 12I (Improved) frigates, comprising twenty-six vessels, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular BBC television drama series Warship. The Leander silhouette became synonymous with the Royal Navy through the 1960s until the 1980s.
The County class was a class of heavy cruisers built for the Royal Navy in the years between the First and Second World Wars. They were the first 'post-war' cruisers constructed for the Royal Navy and were designed within the limits of the Washington Naval Treaty of 1922. Such ships, with a limit of 10,000 tons standard displacement and 8-inch calibre main guns may be referred to as "treaty cruisers".
The Leander class was a class of eight light cruisers built for the Royal Navy in the early 1930s that saw service in World War II. They were named after mythological figures, and all ships were commissioned between 1933 and 1936. The three ships of the second group were sold to the Royal Australian Navy (RAN) before World War II and renamed after Australian cities.
The Arethusa class was a class of four light cruisers built for the Royal Navy between 1933 and 1937 and that served in World War II. It had been intended to construct six ships, but the last pair, Polyphemus and Minotaur, were ordered in 1934 as the 9,100-ton Town-class Southampton and Newcastle.
The Arethusa-class cruisers were a class of eight oil-fired light cruisers of the Royal Navy all ordered in September 1912, primarily for service in the North Sea. They had three funnels with the middle one somewhat larger in diameter than the others. All served in the First World War. They were found to be very cramped internally.
The two Trafalgar-class battleships of the British Royal Navy were late-nineteenth-century ironclad warships. Both were named after naval battles won by the British during the Napoleonic Wars under the command of Admiral Nelson. The two ships were named HMS Nile and HMS Trafalgar.
Enrico Dandolo was the second of two Duilio-class ironclad turret ships built for the Italian Regia Marina in the 1870s. They were fitted with the largest guns available, 450 mm (18 in) rifled, muzzle-loading guns, and were the largest, fastest and most powerful ships of their day. Enrico Dandolo was built in La Spezia, with her keel laid in January 1873 and her hull launched in July 1878. Construction was finally completed in April 1882 when the ship, named for the 41st Doge of Venice, was commissioned into the Italian fleet.
The Orlando class was a seven ship class of Royal Navy armoured cruisers completed between 1888 and 1889.
HMS Phaeton was one of eight Arethusa-class light cruisers built for the Royal Navy in the 1910s. She fought in the First World War, participating in the Battle of Jutland. Following the war, she was scrapped.
HMS Leander was a second class cruiser, name ship of the Royal Navy's first Leander-class cruisers. During a revolution in Panama in 1900, Leander helped protect the lives and property of foreign residents.
HMS Amphion was a second-class cruiser of the Leander class which served with the Royal Navy. She was built at Pembroke Dockyard, being laid down in 1881, launched in 1883, and completed in financial year 1885–86, and then lay in ordinary at Devonport. She was commissioned for the 1887 and 1888 annual manoeuvres. She was recommissioned in December 1888. served in the Pacific until 1890, in the Mediterranean from 1890 to 1895, in ordinary in Devonport from 1895 to 1897 and in the Pacific once more from 1897 to 1904, having a refit in 1900.
HMS Phaeton was a second class cruiser of the Leander class which served with the Royal Navy. Paid off in 1903, she then did harbour service until 1913 at Devonport, where she was used for training stokers and seamen. Sold in 1913 to a charitable institution that ran a training ship for boys based at Liverpool, she was renamed TS Indefatigable until repurchased by the Admiralty in 1941 and renamed Carrick II, whereupon she served as an accommodation hulk at Gourock throughout World War II. In 1946 she was sold to shipbreakers Thos. W. Ward in Preston and broken up in 1947.
HMS Arethusa was a second-class cruiser of the Leander class, which served with the Royal Navy. She was built at Napier, Glasgow, being laid down in 1880, launched in 1882 and completed in financial year 1886–87. She remained in ordinary reserve at Chatham, being commissioned for the 1887, 1888, 1889, 1890, and 1892 annual manoeuvres. She served in the Mediterranean from 1893 to 1896, was commissioned for the 1899 annual manoeuvres, then recommissioned for the Pacific, and later sent as a reinforcement to the China Station during the Boxer Rebellion until she came home for the last time in 1903.
The Forbin class was a group of three protected cruisers built for the French Navy in the late 1880s and early 1890s. The class comprised Forbin, Coëtlogon, and Surcouf. They were ordered as part of a fleet program that, in accordance with the theories of the Jeune École, proposed a fleet based on cruisers and torpedo boats to defend France. The Forbin-class cruisers were intended to serve as flotilla leaders for the torpedo boats, and they were armed with a main battery of four 138 mm (5.4 in) guns.
The French cruiser Fleurus was a torpedo cruiser of the Wattignies class that were built for the French Navy in the early 1890s. The ship had a main battery of five 100 mm (3.9 in) quick-firing guns, complemented by lighter guns and four 356 mm (14 in) torpedo tubes. Launched in 1891 in Rochefort, Fleurus was commissioned into the Mediterranean Squadron as part of the reserve. Trials demonstrated problems with the Admiralty boilers which, despite being replaced twice, meant that the ship was not ready for active service until they were replaced by Niclausse boilers. The cruiser was commissioned into the Northern Squadron in Brest. After 30 months, the cruiser was decommissioned. In 1910, the ship joined the school for engineers at Lorient, and, two years later, returned to Rochefort as a hulk. In 1928, Fleurus was sold to be broken up.
