The Swiftsure class was a group of two British pre-dreadnought battleships. Originally ordered by Chile as the Constitución class during a period of high tension with Argentina, they were intended to defeat a pair of armoured cruisers ordered by the latter country and were optimized for this role. This meant that they were smaller and more lightly armed than most battleships of the time. They were purchased by the United Kingdom in 1903 prior to their completion to prevent their purchase by the Russian Empire as tensions were rising between them and the Japanese Empire, a British ally. Completed the following year, Swiftsure and Triumph had roughly similar careers for the first decade of their service careers. They were initially assigned to the Home Fleet and Channel Fleets before being transferred to the Mediterranean Fleet in 1909. Both ships rejoined the Home Fleet in 1912 and were transferred abroad in 1913, Swiftsure to the East Indies Station as its flagship, and Triumph to the China Station.

After the beginning of World War I in August 1914, Swiftsure escorted troop convoys in the Indian Ocean until she was transferred to the Suez Canal Patrol in December. After defending the Canal in early 1915 from Ottoman attacks, the ship was then transferred to the Dardanelles in February and saw action in the Dardanelles Campaign bombarding Ottoman fortifications. Triumph participated in the hunt for the German East Asia Squadron of Maximilian Graf von Spee and in the campaign against the German colony at Qingdao, China. The ship was transferred to the Mediterranean in early 1915 to participate in the Dardanelles Campaign. She was torpedoed and sunk off Gaba Tepe by the German submarine U-21 on 25 May 1915.[1]

Swiftsure was assigned to convoy escort duties in the Atlantic from early 1916 until she was paid off in April 1917 to provide crews for anti-submarine vessels. In mid-1918, the ship was disarmed and stripped in order to be used as a blockship during a proposed second raid on Ostend. Swiftsure was sold for scrap in 1920.
