The sinking of the Russian ship Ursa Major off the coast of Spain. Background elements of the nuclear reactor

History of the Russian cargo ship Ursa Major shows that the war on military technology is increasingly taking place outside the front lines – on shipping routes, in transport documents and under cover of the civil flag. The ship, which sank off the coast of Spain on 23 December 2024, was supposed to carry unreported nuclear reactor components, possibly intended for North Korea.

According to CNN and Spanish investigators, this was not just a marine disaster, but a case involving a Russian "shadow float", intelligence and illegal transfer of military technology.

Mysterious cargo on the Mediterranean route

According to the disclosure Ursa Major He was formally carrying a non-hazardous cargo. The documents include containers, cranes and elements referred to as "the hatch covers". However, Spanish investigators pointed out two large, unreported facilities placed on the stern of the ship. Each one was to weigh about 65 tons.

According to the findings cited by the media, these could have been VM-4SG reactor housings, or structures used in Soviet and Russian submarines. The captain of the unit, Igor Anisimov, was supposed to tell Spanish investigators that the components carried were components of reactors similar to those used in submarines. According to the Guardian report, the captain also claimed that he was not on board nuclear fuel.

Explosions, acquisition by Russian ship and wreck at a depth of 2,500 meters

Ursa Major sank about 62 nautical miles off the coast of Murcia. Previously, Spanish naval rescue services sent a helicopter, a fast rescue unit, and a tugboat to the area. The Russian ship's crew was to report three explosions in Engineering.

The situation changed on arrival Russian warship, which took action with the damaged unit and ordered Spanish units to move away from the scene. According to Spanish documents, a Russian ship launched flares over Ursa Major. CNN reported that four seismic signals resembling underwater mine explosions or explosions carried out in mining operations were recorded after this event. The wreck is now at a depth of about 2,500 metres.

Has the transport of military technology been interrupted?

The most far-reaching proposal concerns the possibility of intercepting technology transport, which may have been relevant to the North Korean submarine programme. CNN suggested that the sinking Ursa Major It may have been a rare case of technology transfers between Russia and North Korea. However, the perpetrators were not publicly identified and Russia described the incident as a terrorist attack.

This place needs caution. The suspicious cargo, unusual route and subsequent actions of Russian units make more and more questions about the operation of the services appear around this story. However, they do not determine who caused the hull damage or what the full range was cargo carried.

Gibraltar, Ohio type ship and U.S. signal

An additional context is given by the U.S. Navy communication on the entry of an American nuclear submarine type Ohio to Gibraltar on May 10, 2026. The Americans stressed that the presence of the unit was to confirm the ability to operate in key areas and support for allies from NATO.

Such information is not advertised accidentally. OOP type Ohio they are among the most important elements of the American deterrence system, and their position remains generally classified. The publication of an individual's presence in Gibraltar should therefore be regarded as a clear signal to U.S. opponents, not as a simple message of the ship's entry into port.

The sea as a route for the spread of military technology

Case Ursa Major shows that the sea remains a key space for the transfer of military technologies, circumvention of sanctions and hidden actions of states. If the findings of Spanish investigators and CNN are confirmed, we will be faced with one of the most serious cases of suspected transport of nuclear components submarines.

It is no longer just a story of the sinking of a Russian ship. This is a matter that affects maritime security, the illicit spread of military technology and the growing cooperation between Russia and North Korea. In this sense, a wreck at the bottom of the Mediterranean may prove to be more important than many ships that now appear where they are to be spotted.
