	The Kanin class destroyer was built mainly for ASW work.  Arriving in the early 1970's as an updated version of the Koltin class, these vessels were part of the mainstay of Soviet ASW forces during the 1970's and 80's.  These vessels were of primary ASW role, unusual in Soviet design, with only the SA-N-1 for air defence.  All of these vessels were deleted in the early 1990's.
