75 mm 50 caliber Pattern 1892

The majority of ships built or refit between 1890 and 1922 carried Pattern 1892 guns.

During its career the role of the guns evolved from one of anti-torpedo boat defense to coastal artillery and anti-aircraft use.

[1] The original naval mounts produced between 1892 and 1913 had low angles of elevation −7° to +20°.

After the 1917 October Revolution the successor states of Estonia, Finland, Poland and the Soviet Union all used this gun.

The last Finnish warship to carry 75/50 guns was the minelayer Ruotsinsalmi, which was decommissioned in 1975.
