According to the investigation, the Russian ship had docked at the port of Ust-Luga, in the Gulf of Finland, before sailing through the Mediterranean. The chosen route makes no logistical sense if the destination was Vladivostok, on the Pacific coast, as the most direct route would be through the Arctic or the Suez Canal. The passage through waters near Spain suggests that the vessel was following an alternative route, possibly to avoid detection or to carry out a cargo transfer at an intermediate point before heading to North Korea.
Nuclear reactors for North Korea: what was at stake
The possibility that Russia was transferring nuclear technology to North Korea elevates the incident to a different geopolitical category. Nuclear reactors similar to those used in submarines, as described by the Russian ship’s captain to Spanish authorities, are components of high strategic value that could significantly expand North Korea’s nuclear capability. North Korea already possesses nuclear weapons, but the acquisition of compact reactors of Russian origin could accelerate the development of nuclear submarines or new uranium enrichment facilities.
The transfer of nuclear technology between Russia and North Korea violates multiple United Nations Security Council resolutions. These resolutions prohibit the supply of materials, technologies, and knowledge that could contribute to Pyongyang’s nuclear or ballistic missile program. If the CNN investigation is correct, the Russian ship represented a blatant violation of these sanctions, which would explain why Western forces would have decided to intervene so drastically.

The context: North Korean troops in Ukraine and the alliance with Moscow
The sinking of the Russian ship occurred at a time of intensifying military alliance between Russia and North Korea. Two months before the incident, North Korea had sent troops to fight alongside Russian forces in the invasion of Ukraine, an unprecedented move that transformed the relationship between Pyongyang and Moscow from discreet cooperation into an open military alliance. It is estimated that about 15,000 North Korean soldiers were sent to the battlefield.
In exchange for providing troops, missiles, and artillery, North Korea is believed to have received food, fuel, and military technology from Russia. The transfer of nuclear reactors, if confirmed, would represent a qualitative leap in this exchange: not just conventional supplies and armaments, but cutting-edge nuclear technology that could alter the strategic balance on the Korean peninsula. For the United States and its allies in the region, especially South Korea and Japan, this possibility would be unacceptable.
The rescue, the military escort, and Moscow’s silence
The details of the rescue of the Russian ship’s crew also raise questions. After the 14 survivors were rescued by Spanish teams, a Russian military vessel escorting the Ursa Major ordered that the crew be immediately returned to Russian forces. The fact that the cargo ship was being escorted by a military vessel is further evidence that the cargo was not trivial. Cargo ships carrying cranes and ice-breaking equipment do not usually sail with a Navy escort.
The Russian government has never provided an official explanation for the cause of the explosions. Only the Spanish government commented on the case, in a statement published in February 2025, in which it cited the captain’s account of the nuclear reactors. Since then, Moscow’s silence on the incident contrasts with the military missions that Western countries and Russia itself have carried out around the wreckage, indicating that the material at the bottom of the sea continues to be an object of strategic interest for both sides.
A sinking that could rewrite the rules of the game
The case of the Russian ship Ursa Major officially remains unexplained. If the CNN investigation is correct and Western forces did indeed torpedo a Russian military cargo ship to prevent the transfer of nuclear reactors to North Korea, the incident represents an unprecedented operation in the modern era: a direct military action against a Russian asset outside Ukraine, in international waters, without a declaration of war and without public acknowledgment.
What do you think of this investigation into the Russian ship carrying nuclear reactors? Tell us in the comments if you believe the Western torpedo theory, how you assess the alliance between Russia and North Korea, and what you think about Moscow’s silence regarding the sinking.

A Russian ship named Ursa Maior sank in international waters 96 kilometers off the coast of Spain in December 2024 after a series of explosions, and a CNN International investigation revealed that the vessel was carrying components suspected of being nuclear reactors bound for North Korea. Sources linked to the Spanish investigation indicate that the sinking may have been caused by a torpedo launched by Western forces.
According to information released by G1, the Russian ship Ursa Maior was sailing through the Mediterranean on December 23, 2024, two months after North Korea sent troops to fight alongside Russia in Ukraine, when it suffered a series of explosions and sank. Two crew members died and the other 14 were rescued by Spanish teams. The incident was reported by the international press at the time, but the cause of the explosions was never publicly explained. Now, a CNN investigation released this Tuesday (12) reveals that the Russian ship was carrying materials suspected of being nuclear reactors destined for the North Korean government, and that the explosion may have been the result of a rare Western military operation to prevent the transfer of nuclear technology to North Korea.
The Russian government claimed at the time that the Russian ship was transporting cranes for the port of Vladivostok and ice-breaking equipment. But it did not explain why the vessel was near the coast of Spain, thousands of kilometers from the direct route between the Gulf of Finland and the Pacific. The ship’s captain, in a statement to Spanish authorities, stated that the vessel contained “components for two nuclear reactors similar to those used in submarines,” but that he did not know if the material contained nuclear fuel. The contradiction between the official Russian version and the captain’s account is one of the central points of the investigation.
What the CNN investigation revealed
The CNN International report claims to have confirmed multiple elements supporting the thesis that the Russian ship was deliberately sunk. Sources from the ongoing Spanish investigation into the case told the network that the vessel may have been holed by a rare type of torpedo launched by Western forces. If confirmed, the operation would represent one of the boldest military actions in recent years against Russia outside the theater of war in Ukraine.
CNN also confirmed that United States Armed Forces aircraft overflew the Russian ship several times. In the last year, American aircraft overflew the wreckage area at least twice. A Russian spy ship also visited the site a week after the sinking, according to Spanish intelligence sources heard by CNN. As of the latest update to the report, authorities from the allegedly involved countries had not commented on the investigation.
The Ursa Maior: a disguised military freighter
The Russian ship Ursa Maior was not an ordinary commercial freighter. Manufactured in 2009, it is part of the fleet of the company Oboronlogistics, which has a contract with the Russian Ministry of Defense for military construction operations. The direct link of the vessel with the Russian military apparatus reinforces the thesis that the cargo had a strategic purpose and was not merely commercial, as claimed by the Moscow government.
