The damage to the MV Ursa Major's hull had inward-bent edges, indicating the blast originated from outside the ship rather than from internal engine room failure.
Seismographs collected data at the time of the MV Ursa Major sinking consistent with large explosions at the site, as if Russia wanted to blast away any lingering evidence.
The MV Ursa Major's captain testified that the damage pattern was inconsistent with a conventional torpedo but consistent with a supercavitating torpedo, according to the La Verdad article.
