Russia has stepped up the modernization of its nuclear facilities near Europe's borders, with at least five such bases being upgraded or established in recent years. One of them is located just 270 kilometers from Swedish territory, SVT reports, analyzing satellite images.

Journalists received images from Planet Labs from May 2025, which indicate that the Russian base in Kaliningrad, where nuclear weapons may be stored, has been expanded and modernized in recent years.

New buildings, a triple fence, and new communication facilities have appeared on the territory, 270 kilometers from the Swedish territorial border.

At the Osipovichi base in Belarus, the Soviet nuclear weapons storage facility is also being modernized, including a new loading platform for rail transport and air defense, according to nuclear scientists from the American organization FAS.

Swedish Defense Minister Poul Jönsson noted in his comments that Stockholm is closely monitoring Russia's capabilities in this area.

"We know about this and we have been monitoring this for a long time. It is about both Russian investments in nuclear capabilities and the implementation of a new doctrine," he noted.
