Russia maintains its moratorium on nuclear explosive tests while advancing strategic modernization through non-explosive means. Multiple ICBM launches, including a Sarmat test in May 2026 and a solid-fuel system firing from Plesetsk in late August, plus initial sea trials for the Khabarovsk submarine carrying Poseidon drones, have occurred without detonations. Trader consensus reflects low probabilities for a test by late 2026, driven by Russia's focus on delivery systems and test-site readiness at Novaya Zemlya rather than explosive activity. Key variables include any shifts in U.S. policy, diplomatic signals, or verifiable activity at test sites that could alter the balance.
