Russia maintains its voluntary moratorium on explosive nuclear weapons tests while conducting regular exercises of its strategic nuclear forces, including recent ICBM launches from Plesetsk and submarine platforms in the Barents Sea, plus bomber operations simulating nuclear authorization procedures. Analysts note ongoing preparations and infrastructure activity at test sites, alongside statements from Moscow that it would resume testing only if the United States does so to preserve parity following its earlier CTBT de-ratification.

Scheduled strategic drills and winter developments in the war remain key variables for timing.
