It made further sweeps into the central North Sea on 17–19 May and 29–31 May without encountering any German vessels. "Superb" had to be escorted from Devonport on 16 June after the completion of her refit. The Grand Fleet conducted training off Shetland beginning on 11 July. On 2–5 September, the fleet went on another cruise in the northern end of the North Sea and conducted gunnery drills. Throughout the rest of the month, the fleet was performing numerous training exercises before making another sweep into the North Sea on 13–15 October. Almost three weeks later, "Superb" participated in another fleet training operation west of Orkney during 2–5 November. Five days later, the ship was transferred to the 4th Battle Squadron. The fleet departed for a cruise in the North Sea on 26 February 1916; Jellicoe had intended to use the Harwich Force of cruisers and destroyers to sweep the Heligoland Bight, but bad weather prevented operations in the southern North Sea. As a result, the operation was confined to the northern end of the sea. Another sweep began on 6 March, but had to be abandoned the following day as the weather grew too severe for the escorting destroyers. On the night of 25 March, "Superb" and the rest of the fleet sailed from Scapa Flow to support Beatty's battlecruisers and other light forces raiding the German Zeppelin base at Tondern. By the time the Grand Fleet approached the area on 26 March, the British and German forces had already disengaged and a strong gale threatened the light craft, so the fleet was ordered to return to base. On 21 April, the Grand Fleet conducted a demonstration off Horns Reef to distract the Germans while the Imperial Russian Navy relaid its defensive minefields in the Baltic Sea. The fleet returned to Scapa Flow on 24 April and refuelled before proceeding south in response to intelligence reports that the Germans were about to launch a raid on Lowestoft, but only arrived in the area after the Germans had withdrawn. On 2–4 May, the fleet conducted another demonstration off Horns Reef to keep German attention focused on the North Sea. When the dreadnought began a refit later that month, she was relieved by "Superb" as the flagship of the 3rd Division of the 4th BS, commanded by Rear-Admiral Alexander Duff. In an attempt to lure out and destroy a portion of the Grand Fleet, the High Seas Fleet, composed of 16 dreadnoughts, 6 pre-dreadnoughts, and supporting ships, departed the Jade Bight early on the morning of 31 May.
