Russia continues to modernize its strategic nuclear forces through missile tests and exercises amid the ongoing Ukraine conflict and tensions with NATO. A successful Sarmat ICBM test occurred in May 2026, followed by additional Yars launches and a major strategic forces drill on September 23, 2026, involving submarine and bomber components that simulated nuclear authorization procedures. Russia revoked its CTBT ratification in 2023 and maintains a testing moratorium, though officials have signaled readiness to resume if the United States does so first. No explosive nuclear tests have been confirmed. Diplomatic signals, including a recently canceled Trump-Putin meeting, and verification concerns under the expired New START framework remain key variables that could influence future decisions on testing.
