Satellite images reveal that Russia has expanded and modernized at least five nuclear-related facilities near European borders in recent years, Swedish broadcaster SVT reported on June 16, citing new imagery obtained from Planet Labs.
One of the most notable developments is in Kaliningrad, where the suspected nuclear weapons storage site has undergone significant reconstruction.
Images taken in May 2025 show the addition of triple-layered fencing, new buildings, and advanced communications equipment. Polish Foreign Minister Radoslaw Sikorski previously said that up to 100 tactical nuclear warheads might be stored at the site.
Kaliningrad, a militarized Russian exclave between Poland and Lithuania, is a key concern for NATO because of its advanced missile systems and expanding nuclear infrastructure.
The Osipovichi base in Belarus, a former Soviet nuclear storage facility, is also being renovated. Satellite imagery shows new air defense installations and a modernized loading platform for rail-based logistics.
In Novaya Zemlya, a remote Arctic archipelago long linked to Soviet-era nuclear testing, several new buildings have appeared, reinforcing its role as a potential site for future test activities.
On the Kola Peninsula, near the borders with Finland and Norway, Russia has built about 50 storage bunkers for submarine-launched ballistic missiles and constructed a specialized pier for loading those missiles onto submarines, according to the imagery.
Swedish Defense Minister Pal Jonson responded to the findings, saying Stockholm is "closely monitoring" Russian nuclear capabilities. Sweden officially joined NATO in March 2024 after years of non-alignment, citing escalating Russian threats as a primary reason.
The Kremlin has repeatedly used nuclear threats to pressure Ukraine and Western countries since the start of its full-scale invasion in February 2022.

“We don’t know if an exchange of nuclear strikes will begin.” Nuclear conflict risk between Iran and Israel threatens not only the Middle East but also Ukraine, says former Ukrainian Foreign Minister Volodymyr Ohryzko, Radio NV reports.
Israel has carried out a large-scale military operation targeting Iran’s nuclear facilities. The operation, years in the making, resembled Ukraine’s Operation Spiderweb, as both involved coordinated drone swarms launched from hidden bases to cripple enemy infrastructure.
The West might shift its focus to a new crisis, while Russia could financially benefit from rising oil prices.
“If, after all these events, Iran reduces its support to Russia, that would be in our interests,” the diplomat notes.
At the same time, he warned that Israel’s actions might have a dangerous effect: “Who has power is right, and Iran will certainly respond to that.”
Ohryzko emphasizes that Tehran has already declared a strong response, using not only drones but also cruise and ballistic missiles.
“We don’t know what else is stored in Iran’s other sites, whether there are already ready nuclear warheads,” he adds.
According to the expert, Israel’s possession of nuclear weapons is almost an objective reality. Therefore, the risk of nuclear escalation becomes not hypothetical but an extremely realistic scenario.
“So, we don’t know if at some point an exchange of nuclear strikes will begin, and that would be not just dangerous, but horrific,” Ohryzko stresses.
Besides the military threat, there is another consequence — rising energy prices.
“There are reports that oil prices jumped by 12%. That means Russia will profit from this,” the former minister notes.
In such a situation, Ukraine risks losing part of the West’s attention while simultaneously facing the economic strengthening of its main enemy.

Russian President Vladimir Putin claimed that Moscow possesses the world's most advanced nuclear systems but must significantly strengthen its ground forces, Russian state media reported on June 11.
As Russia continues its war against Ukraine, Moscow has increased investment in its military. Russian defense spending has reached its highest level since the Cold War at 6.3% of Gross Domestic Product (GDP).
Putin claimed that Russia's nuclear triad has the highest share of new equipment among nuclear powers.
"Currently, the share of modern weapons and equipment in the strategic nuclear forces is already 95%. This is a good indicator, in fact, it is the highest of all nuclear powers in the world," Russian state media reported Putin saying.
Putin then called for Russia's ground forces to be improved as quickly as possible.
"The dominant force in conducting modern military operations of any scale and intensity remains the ground forces. And it is important to increase their combat capabilities in the shortest possible time," he said.
Russia began its full-scale invasion of Ukraine in February 2022. Russia first began its armed aggression against Ukraine in 2014, when its proxies occupied territory in eastern Ukraine and Russia annexed Crimea.
Russia regularly strikes civilian infrastructure in its ongoing war against Ukraine. On June 11, a Russian drone attack on Kharkiv killed at least three people and injured 64 others.

Russia's nuclear deterrence capabilities have not been significantly impacted in recent Ukrainian drone strikes on several military airfields, Russia's Deputy Foreign Minister Sergei Ryabkov said on June 11.
His comments come days after Ukraine launched a coordinated drone attack, dubbed Operation Spiderweb, targeting at least four major Russian air bases and reportedly damaging dozens of aircraft, including strategic bombers and airborne early warning planes.
Ryabkov claimed that the extent of the damage from the attacks has been "greatly exaggerated" and that none of Russia's strategic forces were weakened.
"Our nuclear deterrence potential against the U.S. and any other potential adversary has not suffered significant damage," Ryabkov said, according to the state-run news agency RIA Novosti.
Russia has repeatedly issued nuclear threats against Ukraine and Western countries since launching its full-scale invasion in February 2022. Those threats have so far not materialized, as Russia continues to wage its war.
The Spiderweb attack was planned over 18 months and carried out by the Security Service of Ukraine (SBU), and is believed to have disabled or destroyed a significant portion of Russia's long-range bomber fleet.
Ukraine claims the operation damaged 41 aircraft and disabled up to 34% of Russia's strategic bombers. Independent satellite imagery has confirmed destruction or damage at several sites, including multiple Tu-95MS and Tu-22M3 bombers at the Belaya air base.
President Volodymyr Zelensky said on June 4 that nearly half of the planes hit in the attack are impossible to repair. NATO estimates that between 10 and 13 Russian planes were completely destroyed, and more were damaged.
Ryabkov previously acknowledged damage to Russian aircraft but claimed that all of them could be put back into service.
