Авро́ра/cruiser Aurora/阿芙乐尔号巡洋舰

Aurora is a 1900 Russian protected cruiser, currently preserved as a museum ship in Saint Petersburg. Aurora was one of three Pallada-class cruisers, 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.

The second ship, Pallada, was sunk by the Japanese at Port Arthur in 1904. The third ship, Diana, was interned in Saigon after the Battle of the Yellow Sea. One of the first incidents of the October Revolution in Russia took place on the cruiser Aurora, which reportedly have fired the first shot, signalling the beginning of the rebellion for those involved.
