Russian underwater intelligence vessel Yantar arrives at the wreck of MV Ursa Major
Yantar likely to survey the wreck of Ursa Major for feasibility of cargo recovery, evidence of sabotage and/or attempt to retrieve or destroy any sensitive Military equipment
The Russian Ministry of Defence Main Directorate of Deep Water Research (GUGI) owned and operated Project 22010 class special purpose intelligence collection vessel “Yantar” which has been operating in the Mediterranean Sea since November 2024, arrived over the datum of the foundered cargo vessel MV Ursa Major during the forenoon, 15 January 2025.
It is worthy of note that Rear Admiral Alexander Konovalov, Commander of the 29th Special Purpose Submarine Brigade which operates special mission craft for GUGI, is likely to be onboard Yantar. During a second port visit to Algiers between 11-14 January 2025, Rear Admiral Konovalov was photographed at a courtesy reception for Yantar with the Algerian Navy Brigadier-General in charge of the 1st Military District at Algiers.
The presence of Rear Admiral Konovalov onboard Yantar suggests he may have deployed to oversee the execution of the underwater investigation of Ursa Major.
With its unique underwater reconnaissance capabilities, consisting of both Manned and Unmanned AUV/ROVs, Yantar is uniquely equipped to conduct a thorough underwater investigation of the wreck and could recover any objects of interest to the investigation team from either within MV Ursa Major or the surrounding area.
There is historical precedence for this and in 2017, whilst operating in the Levant area, Yantar likely recovered or destroyed cryptographic and other sensitive military devices from Russian Mig-29K and Su-33 aircraft which crashed into the sea while operating from Russia’s sole aircraft carrier Admiral Kuznetsov.
Survey for later cargo recovery?
Alternatively, and possibly more likely given the parlous state of Russian heavy engineering, Yantar could also use her embarked underwater capabilities to conduct a feasibility survey of the cargo.
Of note, MV Ursa Major was reportedly carrying two 45-ton hatches destined for Project 10510 class nuclear-powered icebreaker “Rossiya” which is currently under construction at Zvezda shipyard in Bolshoy Kamen. The hatches were visible on deck and it is likely these separated from the deck as Ursa Major sank and are located on the seabed in the vicinity of the datum.
Construction on Rossiya slowed significantly because the original contractor for large metal items was located in Ukraine. That company’s facilities were damaged during Russia’s illegal invasion of Ukraine and heavy metalwork had to be re-contracted to a domestic Russian supplier. With sanctions biting hard, it is likely Russia would want to assess the feasibility of recovering the two 45-ton hatches (at a later date) to re-energize the Project 10510 class construction timeline.
Background
The Oboronlogistika owned MV Ursa Major sank on 23 December 2024 around 46NM north of the Algerian port of Oran in the western Mediterranean Sea whilst conducting a military cargo related mission from the Baltic Sea port of St. Petersburg to Vladivostok. In a report to RIA Novosti, the ship owners believed that Ursa Major sank as a result of a targeted terrorist attack which ship’s crew members described as “three successive explosions on the starboard side, near the stern”.
Russian authorities have almost certainly interviewed the Captain and Engineering Officers of the Ursa Major about the cause of the sinking and it is likely this operation will, in part at least, attempt to corroborate crew accounts and reveal the cause of the sinking which is believed, by Russian authorities, to be a terrorist attack.
It should be borne in mind that MV Ursa Major was engaged in a Military logistics mission at the time of her sinking and it is highly likely she carried sensitive military equipment and documents such as cryptographic codes or communications equipment which Russia will either want to destroy or retrieve.
Alternatively, as Ursa Major was transiting between two military ports, the possibility exists that she was carrying equipment or capabilities of a sensitive nature which Russia would want to protect. If these cannot be recovered to Yantar a controlled demolition of those items would be the most likely course of action.
Update 17 January 2025
Yantar highly likely completed any underwater investigation work to MV Ursa Major datum during late PM 16 January 2025 before heading west highly likely ahead of forecast bad weather in the Alboran Sea which would have precluded further underwater operations for at least the next five days.
It is not known if, or how many visits, Yantar’s underwater vehicles were able to make to Ursa Major but there is a realistic possibility at least one dive was successful before conditions became unfavorable.
Yantar was visually identified departing the Mediterranean Sea by local maritime enthusiasts and OSINT stalwarts, Daniel Ferro, Michael Sanchez and Peter Ferrary during the 1200Z hour, 17 January 2025.
Yantar’s onward routing is not known but a short survey in the North Atlantic is likely before return to homeport Olenya Guba likely around mid-February 2025.

A depth of 2600 meters is hardly a problem for an unmanned deep water vessel - but do Yantar have sufficient lifting capacity to retrieve anything heavy (like an icebreaker reactor hatch) ? And fotos do not suggest room for storage on the aft deck where the cranes are located.
