Russia maintains a moratorium on nuclear explosive tests dating to the Soviet era's final detonation in 1990, while advancing strategic delivery systems and conducting large-scale drills. Recent activity includes October 2026 exercises simulating nuclear command authorization, missile launches from land, sea, and air platforms, and emergency response drills near upgraded command facilities in the Urals. These steps coincide with U.S.-Russia tensions over potential American test resumption and ongoing Ukraine-related friction. Trader assessments of near-term Russian nuclear explosive testing reflect monitoring of official statements, delivery system trials, and any shifts in the Comprehensive Nuclear-Test-Ban Treaty posture.
