The last British pre-dreadnoughts were obsolete before they even entered the Royal Navy's service.

In short: Commissioned in 1908, the Lord Nelson-class battleships were already outclassed by the revolutionary HMS Dreadnought. Despite their advanced design, these ships spent their careers in the shadow of a new naval era, eventually ending their service as target practice and scrap metal in the aftermath of the First World War.

The Lord Nelson class, comprising the Lord Nelson and Agamemnon, represented the final evolution of British pre-dreadnought battleship design. Construction was hampered by significant delays, including the diversion of their main-gun turrets to accelerate the completion of HMS Dreadnought. By the time they commissioned in 1908, the naval landscape had shifted irrevocably toward the all-big-gun battleship concept. Their design was a compromise, constrained by the physical dimensions of existing drydocks at Chatham, Portsmouth, and Devonport, which limited their length and beam.

Technologically, the class was caught in a transition. While they featured a mix of 12-inch and 9.2-inch guns, naval studies by Philip Watts and Vice-Admiral William May had already demonstrated that larger guns offered vastly superior destructive power at range. The ships were designed to keep the range open to mitigate torpedo threats, yet their secondary armament was increasingly viewed as a liability. Naval historian R. A. Burt noted that their armour scheme, while robust, left the magazines vulnerable to plunging fire from long-range engagements, a weakness exacerbated by the waterline belt becoming submerged at deep load.

During the First World War, the sisters served in the Mediterranean, participating in the Dardanelles Campaign and blockading the German battlecruiser Yavuz Sultan Selim. Their service was marked by varied duties, from bombarding Turkish forts to shooting down a German Zeppelin. Following the Armistice of Mudros, which was signed aboard Agamemnon, the ships returned to Britain. Lord Nelson was scrapped in 1920, while Agamemnon was converted into a radio-controlled target ship. She served in this capacity until 1927, marking the final chapter for the Royal Navy's pre-dreadnought era.
