The Lord Nelson class consisted of a pair of pre-dreadnought battleships built for the Royal Navy in the first decade of the twentieth century. Although they were the last British pre-dreadnoughts, both were completed and commissioned well over a year after had entered service in late 1906. and were assigned to the Home Fleet when completed in 1908, with the former ship often serving as a flagship. The sister ships were transferred to the Channel Fleet when the First World War began in August 1914. They were transferred to the Mediterranean Sea in early 1915 to participate in the Dardanelles Campaign. They remained there after the end of that campaign in 1916 and were assigned to the Eastern Mediterranean Squadron, which was later redesignated the Aegean Squadron, to prevent the ex-German battlecruiser and her consort, the light cruiser , from breaking out into the Mediterranean from the Dardanelles, although neither ship was present when the German ships made that attempt in early 1918. Both ships participated in the Occupation of Constantinople in November following the Armistice of Mudros which ended Turkish participation in the war. The sisters returned home in mid-1919 and were placed into reserve upon their arrival. Lord Nelson sold for scrap in 1920, but Agamemnon was converted into a radio-controlled target ship that year and continued in that role until being sold for scrap in early 1927, the last surviving British pre-dreadnought. Background and design Pioneering naval gunnery developments by Captain Percy Scott in the early 1900s were already pushing expected battle ranges out to an unprecedented , a distance great enough to force gunners to wait for the shells to arrive before applying corrections for the next salvo. A related problem was that the shell splashes from the more numerous smaller weapons tended to obscure the splashes from the bigger guns. Either the smaller-calibre guns would have to hold their fire to wait for the slower-firing heavies, losing the advantage of their faster rate of fire, or it would be uncertain whether a splash was due to a heavy or a light gun, making ranging and aiming unreliable. Another problem was that longer-range torpedoes were expected to soon be in service and these would discourage ships from closing to ranges where the smaller guns' faster rate of fire would become preeminent. Keeping the range open generally negated the threat from torpedoes and further reinforced the need
