Since 2023, Russia has claimed to have stationed nuclear weapons in Belarus. As of 2025, there is no conclusive open-source evidence that Russian nuclear warheads and gravity bombs themselves are being stored in Belarus. If they are, the most likely location is a Cold War-era depot near Asipovichy. Russia has also provided nuclear delivery systems and training to Belarusian forces in the form of Iskander-M short-range ballistic missiles and modification and training for Sukhoi Su-25 aircraft and crews to employ nuclear gravity bombs.
Belarus joined the Treaty on the Non-Proliferation of Nuclear Weapons as a non-nuclear-weapons-state in 1994.
