The eight I Squadron ships went into the Baltic on 22 February 1915 for unit training, which lasted until 13 March. Following their return to the North Sea, the ships participated in a series of uneventful fleet sorties on 29–30 March, 17–18 April, 21–22 April, 17–18 May, and 29–30 May. Thüringen and the rest of the fleet then remained in port until 4 August, when I Squadron returned to the Baltic for another round of training maneuvers. From there, the squadron was attached to the naval force that attempted to sweep the Gulf of Riga of Russian naval forces in August 1915. The assault force included the eight I Squadron battleships, the battlecruisers Von der Tann, Moltke, and Seydlitz, several light cruisers, 32 destroyers and 13 minesweepers. The plan called for channels to be swept in Russian minefields so that the Russian naval presence, which included the pre-dreadnought Slava, could be eliminated. The Germans would then lay minefields of their own to prevent Russian ships from returning to the Gulf. Thüringen and the majority of the other big ships of the High Seas Fleet remained outside the Gulf for the entirety of the operation. The dreadnoughts Nassau and Posen were detached on 16 August to escort the minesweepers and to destroy Slava, though they failed to sink the old battleship. After three days, the Russian minefields had been cleared, and the flotilla entered the Gulf on 19 August; reports of Allied submarines in the area prompted a German withdrawal from the Gulf the following day. By 26 August, I Squadron had returned to Wilhelmshaven.On 23–24 October, the High Seas Fleet undertook its last major offensive operation under the command of von Pohl, though it ended without contact with British forces. By January 1916 hepatic cancer had weakened von Pohl to the point where he was no longer able to carry out his duties, and he was replaced by Vice Admiral Reinhard Scheer in January. Scheer proposed a more aggressive policy designed to force a confrontation with the British Grand Fleet; he received approval from the Kaiser in February. Scheer's first operation was a sweep into the North Sea on 5–7 March, followed by two more on 21–22 March and 25–26 March. During Scheer's next operation, Thüringen supported a raid on the English coast on 24 April 1916 conducted by the German battlecruiser force. The battlecruisers left the Jade Estuary at 10:55 and the rest of the High Seas Fleet followed at 13:40. The battlecruiser Seydlitz struck a mine while en route to the target, and had to withdraw. The other battlecruisers bombarded the town of Lowestoft unopposed, but during the approach to Yarmouth, they encountered the British cruisers of the Harwich Force. A short gun duel ensued before the Harwich Force withdrew. Reports of British submarines in the area prompted the retreat of I Scouting Group. At this point, Scheer, who had been warned of the sortie of the Grand Fleet from its base in Scapa Flow, also withdrew to safer German waters.
