 Koldun ( Russian : <unk> ) was an Uragan @-@ class monitor built for the Imperial Russian Navy in Belgium in the mid @-@ 1860s . The design was based on the American Passaic @-@ class monitor , but was modified to suit Russian engines , guns and construction techniques . She was one of two ships of the class to be built in Belgium and assembled in Russia . Spending her entire career with the Baltic Fleet , the ship was only active when the Gulf of Finland was not frozen , but very little is known about her service . She was stricken in 1900 from the Navy List , converted into a coal barge in 1903 and renamed Barzha No. 324 . Abandoned by the Soviets in Finland in 1918 , the ship was later scrapped by the Finns .
