The Warrior-class cruiser was a class of four armoured cruisers built for the Royal Navy in the first decade of the 20th century. After commissioning, all four sister ships were assigned to the Channel and Home Fleets until 1913 when Warrior was transferred to the Mediterranean Fleet. After the start of World War I in August 1914, Warrior participated in the pursuit of the German battlecruiser SMS Goeben and light cruiser SMS Breslau and her three sisters were assigned to the 2nd Cruiser Squadron of the Grand Fleet. Warrior joined the 1st Cruiser Squadron of the Grand Fleet in late 1914. Neither squadron participated in any of the naval battles in the North Sea in 1915. Natal was destroyed by a magazine explosion in late 1915 and only two of the ships participated in the Battle of Jutland in 1916. Cochrane was not engaged during the battle, but Warrior was heavily damaged and sank the following morning.

Achilles was assigned to blockade duty after the battle and sank a German commerce raider in early 1917. Both of the surviving sisters became convoy escorts in 1917 before returning home in 1918. Cochrane supported the Allied intervention in the Russian Civil War in mid-1918. She ran aground in the River Mersey in late 1918 and broke in two. Achilles became a training ship in late 1918 and was sold for scrap in 1921.
