The Bayan-class was the fourth class of armored cruisers built for the Imperial Russian Navy. Ships of the class were in commission from 1902 to 1920.

Design

Right elevation and deck plan as depicted in Brassey's Naval Annual 1902

This class was a considerable advance on previous Russian armored cruisers. These ships were designed as fleet scouts rather than commerce raiders. The two lead ships were built in France and the second pair were built in Russia.

The design for the Bayan-class was developed by the MTK (Morskoi Tekhnicheskii Komitet, or Naval Technical Committee), consisting of representatives of the Russian shipbuilding, armaments, and engineering industries, and the contract was given to the French shipyard Compagnie des Forges et Chantiers de la Méditerranée à la Seine based in Toulon.

The new design was completely different from the three previous types of armored cruisers in Imperial Russian service. The Bayan had little more than half of the displacement (7,775 tons) with almost the same firepower and greater speed than her three predecessors.
