Yes, Russia has been actively relocating nuclear weapons and upgrading the infrastructure to support them. The most significant confirmed movement happened in 2023, when Russia began transferring tactical nuclear warheads to Belarus for the first time since the post-Soviet period. Beyond that, Russia has upgraded roughly half its nuclear storage facilities west of the Ural Mountains over the past decade, deployed nuclear-capable missile systems to its Kaliningrad exclave near NATO borders, and conducted high-profile exercises simulating nuclear warhead transport.
The Belarus Transfer
On June 16, 2023, Russia officially confirmed it had begun moving nuclear warheads into Belarus. The transfer was carried out by rail in at least two phases. The first shipments arrived in June 2023 at the Prudok station in the Vitebsk region, delivering parts, components, and equipment to a Russian aviation base responsible for missile armament and ammunition. A second wave followed in September 2023, when 26 rail wagons carrying warhead components, personnel, and escort security traveled from stations in central Russia to Belarus over a 10-day window.
The weapons likely include warheads for Iskander-M short-range ballistic missile systems and free-fall nuclear bombs designed for Su-25 and Su-30 fighter aircraft. The Iskander warheads can range from 5 to 50 kilotons in yield, while the aerial bombs are smaller, likely under 15 to 20 kilotons, with a combat radius of roughly 350 to 360 kilometers. For context, the bomb dropped on Hiroshima was about 15 kilotons.
The storage site for these weapons is a military depot near Asipovichy in central Belarus. Satellite imagery shows significant construction activity that began in spring 2023, including land clearing and the installation of multiple layers of new interior security fencing, consistent with nuclear warhead storage requirements. A leaked CIA document identified the site, and reports from the ground have noted radiation detection equipment and iodine supplements (used to protect against radiation exposure) present at the facility. Analysis from the Bulletin of the Atomic Scientists describes the site as nearing completion.
Nuclear-Capable Missiles Near NATO Borders
Russia has also deployed Iskander missile systems to Kaliningrad, a Russian territory wedged between Poland and Lithuania on the Baltic Sea. The Iskander is a mobile ballistic missile system with a range of about 500 kilometers (roughly 300 miles) that can carry either conventional or nuclear warheads. Russia initially described these deployments as temporary responses to U.S. military buildup in the Baltic region, but U.S. officials have expressed concern they represent a permanent upgrade. Washington has called the placement of such systems near NATO member states “destabilizing.”
From Kaliningrad, Iskander missiles could reach several NATO capitals and major military installations in Poland, Lithuania, Latvia, and Estonia within minutes of launch. The system replaced the Soviet-era Scud missile and carries two guided missiles per launcher, making it a significant tactical threat regardless of whether it carries a nuclear or conventional payload.
Storage Upgrades Across Western Russia
The Belarus deployment is part of a broader pattern. Russia maintains about a dozen base-level nuclear storage facilities for tactical (shorter-range) nuclear forces west of the Ural Mountains. According to analysis published by the Bulletin of the Atomic Scientists, roughly half of these have been upgraded over the past decade. Russia also added a new storage facility at Morozovsk Air Base in its southern military district while deactivating one near Saint Petersburg at Gatchina. These upgrades suggest Russia is modernizing its ability to store, maintain, and potentially deploy tactical nuclear weapons closer to European borders.
Exercises Simulating Nuclear Operations
In 2024, Russia conducted a series of prominently televised military exercises specifically focused on tactical nuclear weapons. These unfolded in three phases across May, June, and July, and involved a wide range of nuclear-capable platforms: Iskander ground launchers, Tu-22M3 bomber aircraft carrying cruise missiles, MiG-31K jets armed with Kinzhal hypersonic missiles, and sea-launched cruise missiles loaded onto a corvette in the Baltic Fleet. The exercises also included simulated nuclear warhead transports, essentially practicing the logistics of moving live warheads from storage to delivery systems. Joint operations with Belarusian forces were part of the drills.
These exercises served a dual purpose. Operationally, they tested whether Russia’s military could smoothly move warheads and prepare them for use across multiple branches. Politically, they were designed to be seen, sending a signal to NATO and Ukraine about Russia’s willingness to invoke its nuclear arsenal.
Road-Mobile ICBMs
Russia’s strategic nuclear forces also involve constant movement. The Yars mobile intercontinental ballistic missile, which carries multiple independently targeted warheads, has gradually replaced older Soviet-era systems across Russia’s Strategic Missile Forces. These launchers are mounted on heavy transport vehicles and regularly disperse into patrol routes covering areas roughly the size of several European countries, making them extremely difficult to track or target. Russia has been re-equipping missile divisions with Yars systems since 2011, steadily expanding the number of units on mobile patrol from bases in Teikovo, Novosibirsk, Irkutsk, and elsewhere.
Unlike the tactical warhead movements to Belarus, mobile ICBM patrols are a longstanding feature of Russia’s nuclear posture rather than a new escalation. But the continued expansion of Yars deployments means more warheads are on the move at any given time than in previous decades.
What These Movements Signal
The overall picture is one of deliberate repositioning. Russia is placing tactical nuclear weapons further west than at any point since the 1990s, upgrading the facilities to house them, practicing the steps needed to use them, and maintaining a mobile strategic arsenal designed to be constantly in motion. The Belarus deployment in particular crossed a threshold: it marked the first time Russia stationed nuclear weapons on foreign soil since it withdrew them from former Soviet republics after the Cold War. These moves don’t necessarily mean use is imminent, but they represent a meaningful shift in where Russia’s nuclear weapons sit and how quickly they could be made ready.
