The Ursa Major, a Russian cargo ship, sank off the coast of Spain on December 23, 2024, while reportedly carrying components for nuclear reactors intended for North Korea. Officially, the ship was said to be transporting empty containers and cranes, but investigations by Spanish authorities have cast doubt on this narrative. The ship's owner, Oboronlogistics, has previously been licensed to transport nuclear materials. After the ship sank, the surviving crew revealed that the cargo included parts for nuclear reactors similar to those used in submarines. Investigators found evidence suggesting the ship may have been struck by a Barracuda supercavitating torpedo, a weapon used only by a select few countries. Following the sinking, Russian military vessels were observed firing flares and causing additional explosions at the wreck site. The incident has heightened concerns about the implications of Russian support for North Korea, especially in light of North Korea's military activities and ambitions to develop nuclear capabilities.
