Russia is carrying out large-scale nuclear-related activities with Belarus amid rising tensions linked to the Ukraine war. Multiple outlets report that Moscow delivers nuclear munitions to field storage facilities in Belarus and showcases elements of its strategic nuclear forces. In parallel, Russia begins major military exercises with Belarus that include missile systems and naval components, according to the reports. One outlet describes the drills as involving around 64,000 personnel and designed to rehearse operations of Russia’s nuclear forces. The exercises are presented as part of Russia’s broader posture amid heightened regional security concerns, including drone activity in the Baltic and strains in relations between Russia and European NATO members. While the coverage highlights the scale and messaging of these nuclear developments, it does not specify changes in Russian stated nuclear doctrine or any immediate deployment beyond the reported delivery and exercise activity. Taken together, the accounts indicate that Russia is both moving nuclear assets into Belarus and running extensive drills intended to test readiness and coordination of its strategic nuclear capabilities.
