On 29 April 1916, the 3rd Battle Squadron was rebased at Sheerness (where "Africa" arrived on 2 May 1916), and on 3 May 1916 the squadron was separated from the Grand Fleet, being transferred to the Nore Command. "Africa" remained there with the squadron until August 1916. "Africa" began a refit at Portsmouth Dockyard in August 1916. Upon its completion in September 1916, she left the 3rd Battle Squadron and transferred to the Adriatic Sea, where a British squadron had reinforced the Italian Navy against the Austro-Hungarian Navy since Italy's entry into the war in 1915. Admiral Paolo Thaon di Revel, the Italian naval chief of staff, believed that the threat from Austro-Hungarian submarines and naval mines in the narrow waters of the Adriatic was too serious for him to use the fleet for active operations. Instead, Revel decided to implement a blockade at the relatively safer southern end of the Adriatic with the main fleet, while smaller vessels, such as the MAS boats, conducted raids on Austro-Hungarian ships and installations. As a result, she saw little activity while stationed there. She left the Adriatic in January 1917 for a refit at Gibraltar, during which the 6-inch guns on her main deck were replaced with four 6-inch guns a deck higher because the original guns were awash in even slightly rough weather.
