According to Russian state-owned media, the Russian Strategic Nuclear Forces will be transferring tactical nuclear weapons for basing and storage inside Belarus at a specially built facility by July 1st:
“Russia will finish building a special storage facility for tactical weapons in Belarus on July 1, Putin continued. Russia is not transferring tactical nuclear weapons to Minsk, but will deploy them and train the military to handle them like the United States does in Europe, the president said.”
Russian state owned media has also reported that President Putin confirmed Iskander ballistic missiles launchers have already been deployed to Belarus where both nations’ crews are being trained:
“We have already handed over to Belarus our well-known, very effective Iskander complex, it can also be a carrier. From April 3, we will start training the crew and on July 1 we will complete the construction of a special storage facility for tactical nuclear weapons on the territory of Belarus,” Putin said in an interview.”
Belarus had 81 single warhead missiles stationed on its territory after the Soviet Union collapsed in 1991. They were all transferred to Russia by 1996. In May 1992, Belarus acceded to the Nuclear Non-Proliferation Treaty (NPT).
