The Uragan class (also known as the Bronenosetz class, Russian: броненосец, "armor carrier" or "warship") was a class of monitors built for the Baltic Fleet of the Imperial Russian Navy. The ships were built to the plans of the American Passaic-class monitors, a design that was tested on a smaller scale on USS Monitor. A total of 10 ships were constructed at five different shipyards in Saint Petersburg, all entering service in 1865. The ships were among the first ironclad warships in the Russian Navy.
