Kanin-class

The Kanin class, designated Project 57A by the Soviet Union, originated as an extensive modernization of the Project 57bis guided missile destroyers, known to NATO as the Krupny class. These vessels were the first Soviet destroyers designed for guided missiles. Originally intended as gun-armed ships, the design was altered in 1957 by Admiral Sergey Gorshkov to utilize the KSShch anti-ship missile system. Construction occurred between 1957 and 1960, with eight ships of the planned nine completed.

The hull design utilized an enlarged version of the Kotlin class, retaining the same propulsion machinery while incorporating remote control stations and increased electrical capacity. Unlike the Kotlin class, the Kanin class used steel for the superstructure instead of aluminum-magnesium alloys. The initial configuration focused on surface engagement with anti-ship missiles launched from fore and aft positions.

By 1965, the Soviet Navy initiated a reconstruction program to convert the ships into anti-submarine and general-purpose platforms because the primary missile system had become obsolete. This modernization included extending the bow to accommodate a new sonar system and the installation of a helicopter pad for Kamov Ka-25 operations. To enhance defensive capabilities, the ships received surface-to-air missile launchers, anti-aircraft guns, and anti-submarine rocket launchers. Internal modifications included the installation of additional diesel generators to meet increased electrical demand. These rebuilds proved expensive, which deterred the Soviet Navy from further comprehensive modernizations of older vessel classes.

The class entered service between 1960 and 1961, serving with the Northern, Baltic, Black Sea, and Pacific Fleets. Operational roles transitioned from anti-surface warfare to anti-submarine operations following the mid-life conversions. In May 1975, the destroyers Boyky and Zhguchy conducted a visit to Boston, Massachusetts, to commemorate the 30th anniversary of Victory in Europe. This was the first post-war visit by Soviet naval vessels to the United States. Decommissioning of the class began in 1987, and all units were retired from service by 1993.
