Armor

Lava (Russian: Лава) was an Uragan-class monitor built for the Imperial Russian Navy 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. 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 struck from the Navy List in 1900, converted into a barracks ship in 1902 and then into a storage hulk for mines in 1912 and renamed Blokshiv No. 1. During World War I, she was converted into a hospital ship in 1916 and was then abandoned by the Soviets in Finland in 1918; the ship was probably later scrapped by the Finns around 1922.
