China is rapidly overhauling a network of secret facilities used to manufacture warhead components as it expands its nuclear stockpile faster than any other country, according to an analysis of satellite imagery. These changes are taking place as Beijing intensifies efforts to be able to retaliate more quickly against an attack, according to expert assessments of official publications — dramatically raising the stakes of any nuclear standoff.

Russia’s nuclear-capable Oreshnik missile system has entered active service in Belarus, Russia’s Defense Ministry said Tuesday, as the U.S. efforts to broker a deal to end the nearly four-year war in Ukraine have entered a pivotal stage… The ministry’s announcement followed a statement from Belarusian President Alexander Lukashenko, who said earlier this month that the Oreshnik had arrived in the country. Lukashenko said that up to 10 such missile systems will be stationed in Belarus.

Iranian President Masoud Pezeshkian on Tuesday said his country’s answer to an attack would be harsh, which appeared to be in response to a warning by U.S. President Donald Trump over reconstruction of Iran’s nuclear program. “Answer of Islamic Republic of Iran to any cruel aggression will be harsh and discouraging,” Pezeshkian said on the social media platform X. Pezeshkian did not elaborate, but his statement came a day after Trump suggested the U.S. could carry out military strikes if Iran attempts to reconstitute its nuclear program.

The Department of Energy picked three companies on Monday to receive $2.7 billion for domestic uranium enrichment ahead of a 2028 deadline to cut off Russian imports of nuclear power plant fuel. American companies Centrus Energy and General Matter and French enrichment giant Orano will get $900 million each in congressionally appropriated funds, according to a press release, with $28 million for North Carolina’s Global Laser Enrichment. Of the winners, only Orano currently enriches uranium at a commercial scale.

Since Russia annexed Crimea in 2014 and invaded Ukraine in 2022, the rhetoric, prominence, operations, and infrastructures of nuclear weapons in Europe have changed considerably and, in many cases, increased. This trend is in sharp contrast with the two decades prior that—despite modernization programs—were dominated by efforts to reduce the numbers and role of nuclear weapons… In this Nuclear Notebook, we provide an overview with examples of how the nuclear postures in Europe are evolving, especially the infrastructures and operations.
