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. 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. The last was decommissioned in 2003.
