Bogatyr-class cruiser

The Bogatyr class were a group of protected cruisers built for the Imperial Russian Navy.

After the completion of the Pallada class, the Russian Navy issued requirements for three large protected cruisers to three separate companies: Varyag was ordered from William Cramp & Sons in Philadelphia, United States, Askold was ordered from Krupp-Germaniawerft in Kiel, Germany, and Bogatyr from Vulcan Stettin, also in Germany.

Although Askold was the fastest cruiser in the Russian fleet at the time of its commissioning, Bogatyr was selected for further development into a new class of ships.

They were powered by two vertical triple-expansion steam engines, each driving one shaft, which developed a total of 19,500 indicated horsepower (14,500 kW) and gave a maximum speed of 23 knots (43 km/h; 26 mph).

The ships had a range of 2,100 nautical miles (3,900 km; 2,400 mi) at a speed of 12 knots (22 km/h; 14 mph).
