Career.
"Konstantin" was laid down on 16 December 1835 at the Okhta Shipyard in St. Petersburg. The ship was launched on 24 August 1837 and cruised the Baltic in 1839–47. She sailed to Denmark, along with most of the Baltic Fleet, to show the flag during the First Schleswig War between Denmark, Sweden and Prussia. Tsar Nicholas I was determined to support the integrity of Denmark so he deployed a large force in Danish waters for the duration of the war, although it did not actively participate in the war.
"Konstantin" was rebuilt as a screw ship of the line between 1852 and 1854. She transported troops from Sveaborg to Kronstadt in 1856. The ship cruised the Baltic for the next three years before she was laid up. The ship was stricken from the naval list on 8 February 1864 and subsequently scrapped.
