日露和親条約
Pallada () was a sail frigate of the Imperial Russian Navy, most noted for its service as flagship of Vice Admiral Yevfimy Putyatin during his visit to Japan in 1853, which later resulted in the signing of the Treaty of Shimoda of 1855, establishing formal relations between the two countries. In addition to her diplomatic mission, her crew also conducted numerous geographical and natural studies in the Far East. She was scuttled by her own crew in the Crimean War due to the poor condition of her hull in 1855.
