History
In 1891 a Russian naval delegation was shown three guns designed by the French designer Canet. One was a 75/50 gun, one was a 120/45 gun, and the last was a 152/45 gun. All three guns used fixed QF ammunition which produced a rate of fire of 15 rpm for the 75/50 gun, 12 rpm for the 120/45 gun and 10 rpm for the 152/45 gun. The Russians were impressed and in 1892 they negotiated a production license for all three guns.Naval weapons of World War One Friedman Norman 2011-01-01 Seaforth 9781848321007 786178793
Construction
There were two main series of the 120/45 guns produced. The first series of 76 guns were built between 1897 and 1905 at the Obhukov factory. During the Russo-Japanese war a number of barrels of the 152/45 guns burst in action and a strengthened series of 152/45 and 120/45 guns were ordered. 34 of the second series of strengthened guns were built between 1905 and 1915 at the Obhukov factory. Between 1914 and 1916 production switched to the Perm factory and a further 18 strengthened guns were produced there.
Naval use
120/45 guns armed a variety of ships such as armored cruisers, auxiliary cruisers, coastal defense ships, destroyers, gunboats, minesweepers, pre-dreadnought battleships, protected cruisers, seaplane tenders and unprotected cruisers of the Imperial Russian Navy built between 1890 and 1916.http://navalhistory.flixco.info/H/210339x54503/8330/a0.htm FR RU 4.7in 12cm 45cal 1892 QF Single navalhistory.flixco.info
