The 152mm 45 caliber Pattern 1892 was a Russian naval gun developed in the years before the Russo-Japanese War that armed a variety of warships of the Imperial Russian Navy during the Russo-Japanese War and World War I. Guns salvaged from scrapped ships found a second life on river gunboats of the Soviet Navy during the Russian Civil War and as coastal artillery and railway artillery during World War II.^[2] In 1941 it was estimated that there were 196 guns (82 in the Baltic, 70 in the Pacific, 37 in the Black sea and 7 in the Northern fleet) still in use as coastal artillery. After independence in 1917 Finland was estimated to have inherited 100 guns and some remained in use until the 1980s.^[2] The last was decommissioned in 2003.
