The Pervenets-class ironclads were a group of three armored frigates built for the Imperial Russian Navy in the 1860s.

They were sold four years later and Pervenets and Ne Tron Menia were converted into coal barges.

Pervenets survived World War II and was scrapped in the early 1960s, Ne Tron Menia was sunk during the war and scrapped around 1950, while Kreml's fate after her sale is unknown The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells as demonstrated by the Russian destruction of a Turkish squadron at the Battle of Sinope.

A few months later the decision was made to build a third ship, Kreml (Kremlin), at the Neva shipyards in Saint Petersburg.

The last ship in the class, Kreml suffered several serious accidents, accidentally scuttling the frigate Orel in 1869.
