Submarine Reactor Mystery: The Sinking of Ursa Major in the Mediterranean

A Russian ship, Ursa Major, sank in the Mediterranean, possibly carrying submarine nuclear reactor components. The explosion led to a Spanish rescue mission, saving 14 but losing 2 crew members. Investigation revealed potential sabotage, as the ship owner claimed a terrorist attack caused multiple explosions.

The Russian vessel Ursa Major mysteriously sank in the Mediterranean after its engine room exploded, potentially carrying classified submarine reactor components, according to a Spanish government document.

The vessel's perilous journey from St. Petersburg to Vladivostok ended on December 23, 2024, between Spain and Algeria, as 14 people were rescued and two crew members lost.

While Russian state-owned company Oboronlogistika suspects sabotage, the ship's captain reportedly admitted post-rescue that the ship transported nuclear reactor segments for submarines, prompting international scrutiny.
