Construction and description

HMS ''Agamemnon'' was ordered in 1904 and was the first warship built by the William Beardmore and Company's Dalmuir Naval Construction Works. She was laid down on 15 May 1905 and launched on 23 June 1906 before the dockyards themselves were finished. Her completion was greatly delayed by labour troubles and by the diversion of the 12-inch (305 mm) guns intended for her to expedite completion of , and she was not finally completed until June 1908, six months before her sister ''Lord Nelson''.McBride, p. 72 ''Agamemnon'' displaced at deep load as built, with a length of , a beam of and a draft of . She was powered by two inverted vertical triple expansion four-cylinder steam engines, which developed a total of and gave a maximum speed of . The ship was armed with four BL 12-inch Mk X guns arranged in two twin gun turrets, one each fore and aft. Her secondary armament consisted of ten BL 9.2-inch Mk XI guns, in twin gun turrets on each corner of the superstructure, and a single gun turret between them, plus 24 QF 12-pounder 18 cwt guns. She also mounted five submerged torpedo tubes, for which 23 torpedoes were stowed aboard. ''Agamemnon'' had an armour belt at her waterline that was thick, as were the faces and sides of her gun turrets.

Dardanelles campaign, 1915–16

In February 1915, ''Agamemnon'' was ordered to participate in the Dardanelles Campaign. She departed Portland on 9 February, and joined the British Dardanelles Squadron at

She came under heavy fire from Fort Hamidieh on 7 March, taking eight hits from large-calibre shells; one of them, allegedly a round, blew a large hole in her quarterdeck and wrecked the wardroom and the gunroom. She also took several hits by light shells that day, and, although she suffered damage to her superstructure, her fighting and steaming capabilities were not seriously impaired.

On 25 April, ''Agamemnon'' supported the main landings as part of the 5th Squadron, and after that she patrolled to protect Allied minesweeping and netlaying vessels operating in the Dardanelles.

Mediterranean operations, 1916–18

With the end of the Dardanelles Campaign in January 1916, British naval forces in the area were reorganized, and ''Agamemnon'' became part of the

While carrying out these duties, ''Agamemnon'' damaged the Imperial German Navy Zeppelin ''LZ-55'' (''LZ-85'') on 5 May 1916 at Salonika with a shell from a 12-pounder and forced it to crash-land.

After both German ships struck mines, ''Breslau'' sank and ''Goeben'' returned to the Dardanelles before ''Agamemnon'' could arrive on the scene. ''Agamemnon'' underwent a refit at Malta in 1918.

David Beatty, had called for a large target to be provided which would allow realistic gunnery practice for the battleships of the Grand Fleet, which had seen little action since the Battle of Jutland in 1916. Tests against armour plate in 1919 demonstrated that firing 15-inch (381-mm) guns at any pre-dreadnought would sink her quickly, but the use of a pre-dreadnought for target practice and tests by guns of 6-inch calibre (152-mm) or smaller seemed practical. At first, the pre-dreadnought was suggested for target duties, but ultimately ''Agamemnon'' became available and was selected instead.Burt, p. 295 Based on the earlier experience in radio-controlled British drone weapons, ''Agamemnon'' was modified at

for use as a target ship between 6 December 1920 and 8 April 1921.Most sources say that ''Agamemnon'' served as a target ship from 1923 to 1926, and Burt, p. 298, says that she underwent conversion to a radio-controlled target ship from September 1922 to April 1923. However, Burt, p. 295, provides specifics about her conversion to a radio-controlled target ship in 1920–21, as well as specifics about her use as a target in 1921. It is possible that the conversion took place in 1920–1921 and is often confused with a 1922–23 refit. The ship was rewired for radio control and stripped; the 12-inch turrets remained aboard, but all of her guns and their equipment were removed, as were her torpedo equipment, flying deck, sea cabins, main derrick and boat equipment, lower conning tower, masts and yards, most of her crew amenities, and other unnecessary equipment. Unnecessary hatches, coamings, scuttles, and lifts were removed and plated over, and she was ballasted differently than she had been as a battleship. It was not intended to sink her, so she was assigned a crew of 153 to maintain and operate her when she was not under fire. ''Agamemnon''s first target service took place before her modifications were completed. On 19 March 1921, she was exposed to a cloud of poisonous gas to determine the effect of gas on a battleship. It was found that gas could penetrate the ship via her various openings, but the ship had not been sealed against gas before the trial and no accurate results applicable to a commissioned battleship could be obtained. On 21 September, she was subjected to machine-gun fire by strafing aircraft. These trials showed that such strafing could harass a battleship, but could not impair her fighting or steaming capabilities, and helped to determine protection for bridge personnel. ''Agamemnon'' also was used to test the vulnerability of battleships to 6-inch (152-mm), 5.5-inch (140-mm), and 4.7-inch (120-mm) rounds fired at her by ships such as the battlecruisers and while she maneuvered under radio control. These tests showed that ships protected as well as ''Agamemnon'', such as the later dreadnoughts, would suffer damage to their upper works if struck by such shells, but would not have their steaming or fighting capability seriously impaired even by numerous smaller-caliber hits.


Disposal

''Agamemnon'' was relieved as target ship by the dreadnought in December 1926. By then the last British pre-dreadnought battleship in existence, she was sold to J Cashmore of Newport, South Wales, on 24 January 1927 for scrap, and departed
