CMSI Translations #36: The First Joint Underwater Patrol: Starting with the China-Russia “Joint Sea-2025” Exercise

China Maritime Studies Institute – In August of this year (2025), deep within the waters of the Northwestern Pacific, an underwater patrol was reshaping the strategic landscape of the Asia-Pacific. The Russian submarine Volkhov and the Chinese Navy’s submarine Changcheng 210 came together in a joint formation for the first time, traversing the Sea of Japan and the East China Sea to complete a joint underwater patrol spanning more than 2,000 nautical miles.

Russia Maritime Studies Institute – On the 330th Anniversary of the Russian Navy, Admiral Alexander Moiseyev gave his first long interview since he assumed his position as Commander-in-Chief two years ago (2024).

Previously Unknown Russian Surface Drone (USV) Found In Black Sea

Covert Shores – A surface drone (USV) has been found off the coast of Romania, drifting close to the Neptun Alpha drilling platform. As the vessel began to drift away it was hit by cannon fire from a Romanian Air Force F-16 fighter. It was subsequently destroyed by EOD (Explosive Ordnance Disposal) personnel. The black-painted craft appeared to be dead in the water, with seagulls gathering on its hull. It is reported to be of Russian origin. Similar in size to other USVs operated by both sides in the Black Sea, this appears to be a previously unreported type.

Indications Russia Will Re-Route LNG Exports Via Arctic To Avoid Ukrainan Threat

Covert Shores – A Russian LNG (liquified natural gas) tanker, Portovyy (IMO 9246621), has sailed out of the Baltic. Unusually, confusingly, her declared destination of Murmansk in Russia’s Arctic. It is unlikely that she is really going there. Although it is too early to declare it a fact, this may be an early indication that Russia is deploying a new tactic to avoid Ukrainian surface drone (USV) threats.

Russia’s Drone Machinations: Reflexive Control and Cognitive Warfare in the Maritime Domain

CIMSEC – Originating in 1960s Soviet strategic military doctrine, reflexive control (RC) allows the user to employ and orchestrate manipulative tactics, including disinformation, deception, overload, provocation, and distraction, to compel adversaries to voluntarily adopt courses of action favorable to the user’s interests. Since the intensification of the Ukrainian-Russo War and NATO’s extended support to Ukraine, Russia has attempted to reconfigure the environment’s balance of power and assess the limit of the alliance’s collective deterrence.

Covert Maritime Intelligence and Russia’s Shadow Fleet

CIMSEC – At present, Russia is exploiting European seaports and maritime infrastructure. Despite port interception and seizure operations from allied nations, Russia’s acquisition of ghost vessels continues in an upward trend. While primarily used as a strategic tool to augment sanctions evasion and sustain defense expenditures, Russia’s irregular tactics, alongside vulnerable seaport ecosystems, create conditions that could facilitate covert human movement under commercial cover for the Russian Federation.
