The 254 mm 45 caliber Pattern 1891 was a Russian naval gun developed in the years before the Russo-Japanese War that armed coastal defense ships and pre-dreadnought battleships during the Russo-Japanese War and World War I. Guns salvaged from scrapped ships found a second life as coastal artillery. It is believed none were in service during World War II.[2]
