Submarine Mozhaysk Advances in Baltic Tests and Regional Defense Measures

The diesel-electric submarine Mozhaysk conducted a successful deep dive during Baltic tests, reaching a depth of 190 meters. The Baltic Fleet press service reported this milestone, with confirmation from TASS. During the dive, the crew, along with industry representatives, assessed every system and mechanism aboard the submarine. They worked through operating algorithms for submerged navigation and for surfacing from various depths, ensuring the vessel could transition reliably under different conditions. The diving operation was supported by warships and the Baltic Fleet rescue vessel SS-750, ensuring safety measures and contingency plans were in place. Mozhaysk is classified as a multipurpose diesel-electric submarine of project 636.3 Varshavyanka. This project originated from the Rubin Marine Engineering Center Design Bureau and was developed to counter adversary submarines and surface combatants, defend naval bases, support coastal and sea communications, and conduct reconnaissance and patrol missions in enemy maritime zones. In mid-August, official channels reported that Russian strategic missile carriers, including Tu-160 and Tu-95MS, as well as long-range bombers Tu-22M3, carried out planned flights over neutral waters spanning the Baltic, Barents, Norway, East Siberian, Chukchi, and Beaufort seas, including the Arctic Ocean. Later in August, Denis Oslomenko, the Director General of the design and development company Industrial Anti-Espionage Laboratory, announced that the radio-electronic protection complex for tanks against FPV unmanned aerial systems, known as Triton, had its first successful field test in a special operations zone in Ukraine. Former President Vladimir Putin has commented on the future prospects of the Russian army. These events reflect ongoing modernization efforts within the country’s maritime and defense sectors, highlighting the emphasis on advanced submarine capabilities, robust aerial reconnaissance, and electronic protection systems that support strategic operations across multiple theaters. Analysts note that the Varshavyanka class remains a key element in regional deterrence, given its operational reach, endurance, and compatibility with a broad spectrum of missions. The latest tests underscore a disciplined approach to deep-water submarine operations, including rigorous system checks, surface-entry drills, and coordinated support from surface vessels to ensure readiness for real-world scenarios. The combination of versatile underwater performance and integrated defensive technologies demonstrates a continued commitment to maintaining a credible and responsive maritime force in the North Atlantic and adjacent maritime environments.
