context_page_description: The 203 mm 50 caliber Pattern 1905 was a Russian naval gun developed by Vickers for export in the years before World War I that armed a variety of warships of the Imperial Russian Navy. Guns salvaged from scrapped ships found a second life as coastal artillery, railway artillery and aboard river monitors during the Russian Civil War. By 1941 it was estimated there were 36 coastal defense guns and two railroad mounts remaining. During the 1930s a number were relined down to 180 mm and re-designated the 180mm Pattern 1931-1933. These guns were used aboard Kirov-class cruisers or as coastal artillery and railway artillery.
