The Russian ship that sank in the Mediterranean Sea last year was carrying nuclear reactors for North Korea.

The Russian cargo ship Ursa Major, which sank near Cartagena in December 2024, was carrying two nuclear reactor hulls for North Korea.

According to the Spanish publication La Verdad, the ship was part of the so-called Russian “ghost fleet” and was sailing along an atypical route from St. Petersburg to Vladivostok across the Mediterranean Sea.

The Ursa Major was carrying a secret strategic cargo. According to the investigation, these were two VM-4SG nuclear reactor hulls intended for North Korea.

Officially, the captain declared the transportation of empty containers, port cranes and auxiliary equipment, but aerial photographs revealed undeclared heavy containers at the stern.

Spanish services recorded a sharp change in course and loss of speed of the ship on December 22, and on December 23 a distress signal was received 60 nautical miles from Cartagena.

An inspection of the damage revealed a hole in the hull with metal deformation inward, indicating an external attack rather than an internal explosion. The size of the hole did not match that of a conventional torpedo, but was consistent with a supercavitating armor-piercing torpedo without a large warhead.

The Spanish authorities do not rule out that the intervention could have been aimed at disrupting the secret delivery of nuclear technology to the Kim regime.

As previously reported by USM, in late December 2024, the Russian ship Ursa Major, which was actively used to transport military cargo, sank in the Mediterranean Sea.
