The cruiser Bogatyr, launched 1901, was the lead ship of the Bogatyr class of four protected cruisers built between 1898 and 1907 for the Imperial Russian Navy.

Pallada was the last of the four Bayan-class armored cruisers built for the Imperial Russian Navy in the first decade of the 20th century. She was assigned to the Baltic Fleet during World War I where she captured codebooks from the German cruiser Magdeburg that had run aground during the first month of the war. The ship was torpedoed by a German submarine in October 1914 and exploded; none of the crew survived. Pallada was the first warship lost by the Russians during the war.
