'''''Aurora''''' ({{lang-rus|Авро́ра|r=Avrora|p=ɐˈvrorə}}) is a Russian [[protected cruiser]], currently preserved as a [[museum ship]] in [[Saint Petersburg]]. ''Aurora'' was one of three {{sclass|Pallada|cruiser|0}} [[cruiser]]s, built in Saint Petersburg for service in the Pacific. All three ships of this class served during the [[Russo-Japanese War]]. ''Aurora'' survived the [[Battle of Tsushima]] and was interned under US protection in the [[Philippines]], and eventually returned to the [[Baltic Fleet]]. Aurora is most famous for her actions during the [[October Revolution]] where she reportedly fired the shot, that signaled the beginning of the attack on the [[Winter Palace]].

==Russo-Japanese War==
Soon after completion, on 10 October 1903,  ''Aurora'' departed [[Kronstadt]] as part of Admiral Virenius's "reinforcing squadron"  for [[Port Arthur, China|Port Arthur]].<ref>Corbett (2015) Vol. 1, p. 51</ref> 
While in the [[Red Sea]], still en route to Port Arthur, the squadron was recalled back to the [[Baltic Sea]], under protest by [[Stepan Makarov|Admiral Makarov]], who specifically requested Admiral Virenius to continue his mission to Port Arthur.  Only the seven destroyers of the reinforcing squadron were allowed to continue to the [[Far East]].<ref>Corbett (2015) Vol. 1, p. 146, 147</ref>

After her detachment from the reinforcing squadron and her arrival back to home port she underwent new refitting.<ref>{{cite book |last=Kowner |first=Rotem |author-link=Rotem Kowner |year=2006 |title=Historical Dictionary of the Russo-Japanese War |publisher=The Scarecrow Press |isbn=0-8108-4927-5 |page=52}}</ref> After refitting, ''Aurora'' was ordered back to Port Arthur as part of the Russian Baltic Fleet<ref>Corbett (2015) Vol. 2, Chapters I, VI, X, XI, XIII, XIV</ref><ref>British Naval Attache Reports (2003) p. 354 the new redesignation to the 2nd Pacific Squadron was rarely used, in both Corbett texts and official British Naval Attache Reports, the term ''Baltic Fleet'' is mostly consistent.</ref>  ''Aurora'' sailed as part of [[Admiral]] [[Oskar Enkvist]]'s [[Cruiser Squadron]] whose [[flagship]] would be the protected cruiser ''[[Russian cruiser Oleg|Oleg]]'', an element of Admiral [[Zinovy Rozhestvensky]]'s ''Baltic Fleet.''<ref>Corbett (2015) Vol. 2, p. 194, 215, 273</ref> On the way to the Far East, ''Aurora'' received five hits, sustaining light damage from confused friendly fire, which killed the ship's chaplain and a sailor, in the [[Dogger Bank incident]].<ref>Corbett (2015) Vol. 2, p. 35</ref>

During the [[Battle of Tsushima]] the Aurora was only lightly damaged but the ship's captain [[Evgeny Egoriev]] was killed. At nightfall the ''Aurora'' along with the ''Oleg''  were attacked by torpedo boats and at 22:00 they gave up trying to proceed north and headed southwest.<ref name=Pleshakov289>{{cite book |last=Pleshakov |first=Constantine |title=The Tsar's Last Armada |publisher=Perseus Press |date=2002 |isbn=1-903985-31-5 |pages=289-291}}</ref> Once dawn arrived it was found that [[Russian cruiser Zhemchug|Zhemchug]] had retreated with the other two ships.<ref name=Pleshakov292 /> Enkvist decided transfer his command to the Aurora then take his ships to [[Manila]] and American internment.<ref name=Pleshakov292>{{cite book |last=Pleshakov |first=Constantine |title=The Tsar's Last Armada |publisher=Perseus Press |date=2002 |isbn=1-903985-31-5 |pages=292-293}}</ref> On the way to Manila the ship's doctor managed to set up the ship's X-ray equipment and performed the first post battle X-rays in Russian naval history.<ref name=Pleshakov296>{{cite book |last=Pleshakov |first=Constantine |title=The Tsar's Last Armada |publisher=Perseus Press |date=2002 |isbn=1-903985-31-5 |page=296}}</ref> Evgeny Egoriev was buried at sea June 3 1905.<ref name=Pleshakov297>{{cite book |last=Pleshakov |first=Constantine |title=The Tsar's Last Armada |publisher=Perseus Press |date=2002 |isbn=1-903985-31-5 |page=297}}</ref>

==World War I, Mutiny and Revolution==
During [[World War I]] ''Aurora'' operated in the Baltic Sea performing patrols and shore bombardment tasks. In 1915, her armament was changed to fourteen 152&nbsp;mm (6&nbsp;in) guns. In late 1916 she was moved to [[Petrograd]] for repairs.<ref name=":0">{{Cite web |last=BUDAKLI |first=Maritime Goods-Eren |title=Avrora Cruiser - Maritime Goods |url=https://www.maritimegoods.com/en/content-details/avrora-cruiser-.html?ContentID=633 |access-date=2025-02-08 |website=www.maritimegoods.com |language=en}}</ref> 

By late 1916, when ''Aurora'' arrived in Petrograd, conditions in the capital had deteriorated and the city was lawless and suffering from a cold winter and food shortages. Dissatisfaction with the Tsar was approaching a breaking point.<ref>{{Cite web |last=alphahis |date=2012-12-10 |title=A police report on deteriorating conditions in Petrograd (1916) |url=https://alphahistory.com/russianrevolution/police-conditions-in-petrograd-1916/ |access-date=2025-02-08 |website=Russian Revolution |language=en-AU}}</ref> 

During the [[February Revolution]] a significant number of the enlisted men had become sympathetic with, or had outright joined the [[Bolsheviks]]. This led to increasing tensions between the officer class - who were generally Tsarists - and the enlisted men.<ref name=":1">{{Cite web |last=Other |first=A. N. |date=2016-03-22 |title=Aurora: the Ship that Started a Revolution |url=https://navyhistory.au/aurora-the-ship-that-started-a-revolution/ |access-date=2025-02-08 |website=Naval Historical Society of Australia |language=en-AU}}</ref>

Tensions came to a head after officers fired their pistols at the enlisted men in an attempt to restore order. The crew captured the ship's captain, Mikhail Nikolsky, and ordered that he carry a red flag as a symbol of support for the Bolshevik cause. When he declined, he was shot and killed as were an unknown number of the ship's officers.<ref name=":2">{{Cite web |title=The end of the line for the Aurora? |url=https://www.opendemocracy.net/en/odr/end-of-line-for-aurora/ |access-date=2025-02-08 |website=openDemocracy |language=en}}</ref><ref name=":1" />

A revolutionary committee was formed and a new captain was elected. The ship joined the Bolshevik cause and became the first major Russian warship to fly the red flag of the Bolshevik cause.<ref name=":0" /><ref name=":3">{{Cite web |last=Beckett |first=Jesse |date=2022-02-14 |title=The Cruiser Aurora Signaled the Start of the Russian Revolution |url=https://www.warhistoryonline.com/instant-articles/russian-cruiser-aurora.html |access-date=2025-02-08 |website=warhistoryonline |language=en}}</ref><ref name=":1" />

On the eve of the [[October Revolution]] the ship was assigned to dislodge loyalist military cadets from the [[Nikolayevsky Bridge]]. After carrying out that assignment, the ship fired the famous blank shot that, according to Russian lore, was the signal to begin the assault on the Winter Palace. It is for this action that the ship is best known and most closely identified in Russian culture.<ref>{{Cite web |title=The Cruiser Aurora Museum in St. Petersburg, Russia |url=http://www.saint-petersburg.com/museums/cruiser-aurora/ |access-date=2025-02-08 |website=www.saint-petersburg.com}}</ref><ref name=":2" /><ref name=":3" />

In 1918 Aurora was relocated to the naval dockyard at Kronstadt and her new 6-inch guns were removed and installed on floating batteries to be used by the Bolsheviks during the civil war.<ref name=":1" /> 

==Second World War==
In 1922, ''Aurora'' returned to service as a training ship. 

During the Second World War, her guns were taken from the ship and used in the [[Siege of Leningrad|land defence]] of [[Saint Petersburg|Leningrad]]. The ship herself was docked in [[Lomonosov, Russia|Oranienbaum]] port,<ref name="RussiaBeyond">{{cite web |url=http://rbth.com/arts/2014/11/07/aurora_the_cruiser_that_sparked_a_revolution_or_did_it_41229.html |title=Aurora: The cruiser that sparked a revolution – or did it? |first=Sofía |last=Sávina |date=7 November 2014 |website=Russia Beyond}}</ref> and was repeatedly shelled and bombed. On 30 September 1941, she was damaged and sunk in the harbour.

She was later salvaged and repaired after the war.

==Post World War II==
The ship was opened as a museum ship in Leningrad in 1957, as a monument to the October Revolution.<ref>{{Cite web |last=Mancebo |first=Ivanka Garcia |title=Russian Cruiser Aurora - Opening times, prices & location |url=https://www.introducingsaintpetersburg.com/russian-cruiser-aurora#:~:text=During%20World%20War%20II,%20Aurora,a%20museum%20ship%20in%201957. |access-date=2024-09-08 |website=www.introducingsaintpetersburg.com |language=en}}</ref>

After having served as a museum ship for 27 years, 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 decommissioned {{ill|Ruchi Naval Base|ru|Ручьи (военно-морская база)}}, and sunk near the shore. The restoration revealed that some of the ship's parts, including the armour plates, were originally made in Britain.<ref>{{Cite web |title=Aurora |url=https://www.museumships.us/russia/aurora |archive-url=https://web.archive.org/web/20200113210845/https://www.museumships.us/russia/aurora |url-status=dead |archive-date=13 January 2020 |access-date=2021-03-18 |website=Museum Ships.us |language=en-US}}</ref>

In January 2013, Russian Defence Minister [[Sergey Shoygu]] announced plans to recommission ''Aurora'' and make her the flagship of the [[Russian Navy]] due to her historical and cultural importance.<ref>{{cite web |url=http://2-news.ru/info/politics/211-avrora_vernetsya_v_stroy_.html |title="Аврора" вернется в строй |trans-title="Aurora" will return to service |date=27 January 2013 |website=Dve Novosti |language=ru |access-date=5 June 2021 |url-status=dead |archive-url=https://web.archive.org/web/20131020195049/http://2-news.ru/info/politics/211-avrora_vernetsya_v_stroy_.html |archive-date=2013-10-20}}</ref> On 21 September 2014, the ship was towed to the [[Admiralty Shipyard]] in [[Kronstadt]] to be overhauled,<ref name="RussiaBeyond" /><ref>{{cite web |url=https://www.youtube.com/watch?v=v45NA2LtlKI  |archive-url=https://ghostarchive.org/varchive/youtube/20211221/v45NA2LtlKI |archive-date=2021-12-21 |url-status=live|title=Russian Revolution Symbol: Iconic 'Aurora' cruiser towed to renovation port |author=RT |date=21 September 2014 |via=YouTube}}{{cbignore}}</ref> to return in 2016.<ref>{{cite news |url=http://en.itar-tass.com/russia/754118 |title=Legendary Aurora to return to its harbour after overhaul in 2016 |date=13 October 2014 |website=TASS}}</ref> On 16 July 2016, she returned to her home harbour in Saint Petersburg.<ref>{{cite news |url=https://www.heraldnet.com/news/bolshevik-revolution-warship-aurora-returns-to-st-petersburg/ |title=Bolshevik Revolution warship Aurora returns to St. Petersburg |date=16 July 2016 |newspaper=[[The Everett Herald]]}}</ref>

== In popular culture ==
The 1965 Soviet film ''[[The Salvos of the Aurora Cruiser]]'' shows the ship's action in the October Revolution.<ref>{{Cite web |title=Призрак бродит по экрану |url=https://portal-kultura.ru/articles/cinema/173409-prizrak-brodit-po-ekranu/ |access-date=2024-09-08 |website=portal-kultura.ru |language=ru}}</ref>

In 1973, a short film about the ship, titled ''Aurora'', was released.<ref>{{Citation |last=Kachanov |first=Roman |title=Avrora |type=Animation, Short |url=https://www.imdb.com/title/tt2331648/ |access-date=2024-09-08 |others=Viktor Filippov, Aleksey Konsovskiy, Klara Rumyanova |publisher=Soyuzmultfilm}}</ref>

=== Aurora Flags ===
Due to the honoring of the ship with high state awards, the flag flown at the stern is a special version of the main Naval Ensign. This tradition dates back to 1927, when the aurora was awarded the [[Order of the Red Banner]] and lasted until the end of [[Soviet Navy]] and was then resumed after returning from a major overhaul in 2016.<ref>{{Cite web |url=http://guide.travel.ru/russia/246205.html |title=Крейсер-музей "Аврора" |access-date=2016-12-27 |archive-date=2016-12-28 |archive-url=https://web.archive.org/web/20161228123923/http://guide.travel.ru/russia/246205.html}}</ref>
