"Bayern" and "Baden" were commissioned into the fleet in July 1916 and March 1917, respectively. This was too late for either ship to take part in the Battle of Jutland on 31 May and 1 June 1916. "Bayern" was assigned to the naval force that drove the Imperial Russian Navy from the Gulf of Riga during Operation Albion in October 1917, though the ship was severely damaged by a mine and had to be withdrawn to Kiel for repairs. "Baden" replaced as the flagship of the High Seas Fleet, but saw no combat.
