Over the winter of 1906–1907, "Kaiser Wilhelm der Grosse" underwent a major overhaul in Kiel, which was completed by the end of April. By this time, the newest s were coming into service; along with the s, these provided enough modern battleships to create two full battle squadrons. As a result, the "Heimatflotte" was renamed the "Hochseeflotte" (High Seas Fleet). Starting on 13 May, major fleet exercises took place in the North Sea and lasted until 8June with a cruise around the Skagen into the Baltic. The fleet began its usual summer cruise to Norway in mid-July. The fleet was present for the birthday of Norwegian King Haakon VII on 3August. The German ships departed the following day for Helgoland, to join exercises being conducted there. The fleet was back in Kiel by 15 August, where preparations for the autumn maneuvers began. On 22–24 August, the fleet took part in landing exercises in Eckernförde Bay outside Kiel. The maneuvers were paused from 31 August to 3September when the fleet hosted vessels from Denmark and Sweden, along with a Russian squadron from 3to 9September in Kiel. The maneuvers resumed on 8September and lasted five more days.
