Russia maintains its voluntary moratorium on nuclear explosive tests since 1990, with trader consensus reflecting low probability of a detonation by late 2026 amid ongoing diplomatic and strategic calculations. Recent developments include successful tests of delivery systems such as the Burevestnik nuclear-powered cruise missile and Poseidon underwater drone, alongside large-scale strategic nuclear forces exercises simulating authorization procedures and ICBM launches from submarines and land bases. Russian officials, including President Putin and Foreign Minister Lavrov, have reiterated readiness for reciprocal measures only if the United States resumes testing first, following U.S. rhetoric and accusations of low-yield activities by others. These steps emphasize modernization of arsenals and signaling without violating the test ban, while scheduled military drills and diplomatic timelines continue to shape assessments of escalation risks.
