2nd Detached Squadron in the Adriatic Sea to reinforce the Italian Navy after Italy declared war on Austria-Hungary. Implacable arrived at Taranto, Italy, her base for this duty, on 27 May 1915. In November 1915, Implacable transferred to the 3rd Detached Squadron. Based at Salonika, this squadron was organised to reinforce the Suez Canal Patrol and assist the French Navy in blockading the Aegean coasts of Greece and Bulgaria. She shifted her base to Port Said, Egypt, later that month. Implacable departed on 22 March 1916 for a refit in the United Kingdom, arriving at Plymouth Dockyard on 9 April 1916. When her refit was complete, she returned to the 3rd Detached Squadron and was based at Salonika. In June 1917, Implacable was at Athens during the abdication of King Constantine I of Greece. In July 1917, Implacable returned to the United Kingdom and paid off at Portsmouth to provide crews for anti-submarine vessels, and four main-deck casemates on either side were replaced by two 6-inch guns on her battery deck. She was laid up until March 1918, when she was selected for service as a depot ship with the Northern Patrol at Lerwick, Kirkwall, and Buncrana. In the conversion, she kept her main battery and the four upper-deck 6-inch guns, but the rest of her 6-inch guns were removed, as were her anti-torpedo nets. In November 1918, Implacable was placed on the disposal list, paid off in 1919, and on 4 February 1920 was placed on the sale list. She was sold for scrapping to the Slough Trading Company on 8 November 1921. Resold to a German firm, she was towed to Germany for scrapping in April 1922.
