The 6 inch 35 caliber naval gun 1877 was a 152 mm

Second World War.[1][2] Russian model year 1877 refers to rifling system, not gun adoption[citation needed
].

Background

Russian Empire

de Bange obturator.[1][2][3]

Modifications and mountings

While the first guns were being constructed, technology for making

wire-wound guns was purchased from the United Kingdom in 1885. After the first batch of guns was completed in 1887 production was changed to wire-wound model. At the beginning of the 1890s a simplified wire-wound version was developed in Russia and was used in the production of the remaining orders. The adoption of 6 inch 45 caliber Canet gun halted the production of the older 6 inch 35 caliber gun.[1][2]

Putilov factory developed Vavasseur mounting for the gun in 1886 that had the central pivot at the centre of the mount and a circular base plate allowing 360° traverse. This mounting was used on deck gun installations. In 1887 Vavasseur-Dubrov or simply Dubrov mount was developed. For casemate guns a Krel mounting was developed in 1886 that had the central pivot at the front of the mount with the rear of the mounting traversing on steel rollers.[1]

Service

The 6 inch 35 caliber gun formed the standard

ironclads and also on gunboats. During the Russo-Japanese War most of these ships had been fitted with the newer 6 inch 45 caliber Canet guns. During the First World War fourteen guns were used as coastal guns on Gulf of Finland in Peter the Great's Naval Fortress and were taken over by Finland after Finland's Declaration of Independence in 1917.[2]

Service in Finland

Following Finland's independence the fourteen 6 inch 35 caliber guns on Vavasseur mountings in the coastal forts of

Gulf of Vyborg and Koivisto area were taken over by Finland. Six guns were in Härkölä and four guns both in Tuppura and Humaljoki. The Finnish designation for the gun was 152/35 Mk or 152 mm:n 35 kaliiperin merikanuuna (152 mm 35 caliber coastal gun). The "Mk" designation means simply coastal gun (merikanuuna); unlike other coastal guns in Finnish use this gun did not receive a manufacturer marking. The batteries in Härkölä and Tuppura were dismantled prior to Winter War and the guns moved first to Lake Ladoga and later to Archipelago Sea: two guns in Lypertö, three in Bokulla, three in Lökholm and one in Pensar.[4] Humaljoki battery supported Finnish troops in Winter War by shelling Soviet positions including troops attempting to cross over frozen sea. When Soviet forces breached the Mannerheim Line in February 1940 the battery crew fired off their remaining ammunition and destroyed the guns on the night between 19th and 20 February 1940 when the fort was abandoned.[1][5][6]

During Continuation War the gun was used on Archipelago Sea and during the trench warfare period also on Lake Ladoga at Saunaniemi.[7] At the end of Continuation War there were seven guns remaining, two at Lypertö, three at Bokulla and two at Ristisaari. Additionally three spare barrels were stored in Helsinki Naval Base. After the war one gun was placed on display at Suomenlinna and the rest were scrapped.[1]
