During the First World War the ship operated in the Baltic Sea. In 1915, her armament was changed to fourteen 152 mm (6 in) guns. At the end of 1916, the ship was moved to Petrograd (the renamed St Petersburg) for a major repair. The city was brimming with revolutionary ferment and part of her crew joined the 1917 February Revolution. A revolutionary committee was created on the ship, with Aleksandr Belyshev elected as its captain. Most of the crew joined the Bolsheviks, who were preparing for a Communist revolution. According to the Soviet account of history, on 25 October 1917, Aurora refused to carry out an order to put to sea, which sparked the October Revolution. At 9.45 p.m on that date, a blank shot from her forecastle gun signaled the start of the assault on the Winter Palace, which was to be the last episode of the October Revolution. The cruiser’s crew allegedly took part in that attack.
In 1922, Aurora was brought to service again as a training ship. During the Second World War, the guns were taken from the ship and used in the land defence of Leningrad. The ship herself was docked in Oranienbaum port, and was repeatedly shelled and bombed. On 30 September 1941 she was damaged and sunk in the harbour. After extensive repairs in 1945 – 1947, Aurora was permanently anchored on the Neva in Leningrad (now St Petersburg) as a monument to the Great October Socialist Revolution and in 1957 became a museum-ship.
As a museum ship, the cruiser Aurora became one of the many tourist attractions of Leningrad (now Saint Petersburg), and continued to be a symbol of the October Socialist Revolution and a prominent attribute of Russian history. In addition to the museum space, a part of the ship continued to house a naval crew whose duties included caring for the ship, providing security and participating in government and military ceremonies. The crew was considered to be on active duty and was subject to military training and laws.
Having long served as a museum ship, from 1984 to 1987 the cruiser was once again placed in her construction yard, the Admiralty Shipyard, for capital restoration. During the overhaul, due to deterioration, the ship’s hull below the waterline was replaced with a new welded hull according to the original drawings. The cut off lower hull section was towed into the Gulf of Finland, to the unfinished base at Ruchi, and sunk near the shore. The restoration revealed that some of the ship parts, including the armour plates, were originally made in England, which put in doubt the previously maintained image of the cruiser as a marvel of authentic Russian naval engineering.
Aurora stands today as the oldest commissioned ship of the Russian Navy, still flying the naval ensign under which she was commissioned, but now under the care of the Central Naval Museum. She is still manned by an active service crew commanded by a Captain of the 1st Rank. From 1956 to the present day 28 million people have visited the cruiser Aurora.
