The Bogatyr class were a group of protected cruisers built for the Imperial Russian Navy. Unusually for the Russian navy, two ships of the class were built for the Baltic Fleet and two ships for the Black Sea Fleet.

Description

After the completion of the Pallada-class cruiser, the Russian Navy issued requirements for three large protected cruisers to three separate companies: RUSSIAN CRUISER Varyag was ordered from William Cramp & Sons in Philadelphia, United States, RUSSIAN CRUISER 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. The Bogatyr-class cruisers normally displaced 6340 LT. The ships had an overall length of 134.9 m, a beam of 16.4 m and a mean draft of about 6.8 m. They were powered by two vertical triple-expansion steam engines, each driving one shaft, which developed a total of 19500 ihp and gave a maximum speed of 23 kn. The engines were powered by 16 coal-fired Belleville boilers. The ships had a range of 2100 nmi at a speed of 12 kn. The standard crew consisted of 573 officers and men. The ships were rearmed during World War I with fourteen 55-caliber 130 mm B7 Pattern 1913 guns in single mounts, four of which were mounted in casemates. The anti-aircraft armament consisted of two 75 mm guns. The armored deck and the casemates were 76 mm thick. The armor of the conning tower was 152 mm thick.
