Ukraine’s military intelligence says it has hacked into one of Russia’s newest and most powerful nuclear submarines. The submarine, named Knyaz Pozharsky, had only recently joined the Russian Navy.
Ukraine Claims Major Hack on Russian Nuclear Submarine
It belongs to a group of top-secret submarines called the Borei-A class, which form a big part of Russia’s nuclear defense system.
According to Ukraine, hackers were able to steal a huge amount of confidential information from the submarine’s systems. This includes technical blueprints, engineering reports, crew rosters, and even instructions used during combat. They also claimed to have downloaded a full schedule of the submarine’s daily operations — everything from patrols to routine checks.
Ukrainian military intelligence said that this data could also reveal weaknesses not just in the Knyaz Pozharsky, but in other submarines of the same class. These are high-tech vessels designed to launch nuclear missiles and travel without being detected. They are said to be key to Russia’s image as a global military power.
The hacking, if true, could be a serious blow to the secrecy of Russia’s military and its submarine fleet. The Russian government has not made any public statements about the hack. Also, no cybersecurity experts or Western governments have confirmed if Ukraine’s claim is true.

Leaked Files Include Submarine’s Secrets and Crew Information
The Knyaz Pozharsky submarine entered service in late July and is based in the Murmansk region, within Russia’s Northern Fleet. This submarine can carry 16 long-range missiles, and each missile can carry multiple nuclear warheads. These submarines are designed to move quietly, avoid detection, and launch powerful attacks if needed.
Ukraine says the stolen files provide detailed knowledge of how the submarine works. These include secret combat plans and design details that are not shared with the public. One of the most sensitive parts of the hack is said to be the full crew list and daily operation charts. This means hackers may know who operates the submarine and what they do each day.
Ukrainian officials said this data might help identify problems in the design or functioning of other Borei-A class submarines. These submarines are a major part of Russia’s nuclear strategy and a strong symbol of its military strength.

This cyberattack is one of many intelligence operations Ukraine claims to have carried out during the ongoing conflict with Russia. Earlier, in June, Ukraine launched a large drone strike called “Operation Spider’s Web” that targeted Russian airfields and damaged aircraft used in nuclear missions.
Tensions Rise as Naval Drills and Nuclear Moves Continue
The news about the hacking came out on the same day as a naval drill. Russia and China held the drill together. It took place in the Sea of Japan. The focus was on anti-submarine training. These drills are part of their ongoing military partnership.
At the same time, the United States has taken new steps in the region. Reports say American President Donald Trump ordered two U.S. nuclear submarines to be moved into “appropriate areas” after strong words from a top Russian official. These events highlight the rising tensions involving nuclear forces in the region.
In recent months, Russia has talked a lot about its nuclear weapons. No nuclear weapons have been used in the war. But Russian leaders keep giving warnings about them. They also plan to grow their nuclear power. Russia wants to build more submarines by 2030. Some of these will carry special underwater drones with nuclear warheads.

The Arctic is now an important area. Russia’s Northern Fleet controls the hacked submarine. It often trains under the ice in the Arctic. Russia has added more troops and built new bases there. It is also looking for energy in the region. Other countries are watching the area closely. Melting ice has opened up new sea routes.
As of now, Russia has not confirmed any of Ukraine’s claims. It remains unclear how much damage the hack has caused, but if true, this cyberattack could be one of the most damaging blows to Russia’s nuclear secrecy in recent years.
