I doubt it. The USSR / Russia concept of operations for nuclear missile submarines is way different from NATO countries. They don't typically conduct wide-ranging strategic deterrence patrols out in the open ocean. Instead they tend to stay in or near their own territorial waters, protected by surface warships and land-based aircraft. While US attack submarines have occasionally violated Russian territorial waters for special missions they don't do so on a regular basis because it's so dangerous.
