Here Are All the Submarines of the Russian Navy in One Infographic

The Russian Navy’s submarine force is one of those military topics that sounds simple until you try to count it. Then, suddenly, you are knee-deep in NATO reporting names, Russian project numbers, nuclear deterrence jargon, Cold War leftovers, and enough “K” hull numbers to make your spreadsheet quietly give up and move to the countryside.

Still, the big picture is clear: submarines remain the most important part of Russia’s navy. While many Russian surface ships are aging or constrained by sanctions, geography, and combat losses, the undersea fleet is where Moscow still fields some of its most dangerous and modern military technology. From ballistic missile submarines hiding under Arctic ice to quiet diesel-electric Kilo-class boats lurking near coastal waters, Russian submarines are designed to deter, strike, spy, and complicate NATO planning.

Open-source estimates usually place the Russian submarine fleet at roughly 60-plus boats, though not all are fully operational at the same time. Some are in overhaul, some are technically “active” but rarely deploy, and some belong to special-purpose units that make counting them feel less like naval analysis and more like detective work with a fog machine.

Russian Navy Submarines at a Glance

Think of the Russian submarine force as four overlapping families: nuclear ballistic missile submarines, nuclear cruise missile and attack submarines, diesel-electric attack submarines, and special-purpose submarines. Each category has a different job, and together they form the underwater backbone of Russian sea power.

Ballistic Missile Submarines: Russia’s Underwater Nuclear Shield

The most strategically important Russian submarines are ballistic missile submarines, known as SSBNs. Their job is not to win a flashy naval duel. Their job is to disappear, survive a first strike, and preserve Russia’s ability to retaliate with nuclear weapons. In nuclear strategy, that makes them a very big deal.

Borei and Borei-A Class

The Borei class, including the improved Borei-A variant, is the modern face of Russia’s sea-based nuclear deterrent. These submarines are replacing older Soviet-era boats and are designed to be quieter, more reliable, and better suited for long patrols. Each Borei carries 16 Bulava submarine-launched ballistic missiles, giving one boat enough strategic firepower to make defense planners sit up very straight in their chairs.

The Borei-A variant improves the original design with changes to the hull, electronics, acoustic signature, and overall performance. Recent additions such as Knyaz Oleg, Generalissimus Suvorov, Imperator Aleksandr III, and Knyaz Pozharsky show that Russia has prioritized this program even while other shipbuilding projects struggle. The plan is generally understood to be a balanced Borei force split between the Northern Fleet and Pacific Fleet.

In practical terms, Borei submarines matter because they give Russia a survivable nuclear option. Their Arctic patrol routes, protected bastion areas, and support from air and surface forces make them difficult targets. They are not invinciblenothing in naval warfare isbut they are among Russia’s most valuable military assets.

Delta IV Class

The Delta IV class is older, but not irrelevant. Built in the final years of the Soviet Union, these submarines still serve mainly with the Northern Fleet. They carry Sineva or Layner submarine-launched ballistic missiles and remain part of Russia’s strategic nuclear force while the Borei fleet expands.

The Delta IVs are like the veteran pitchers of the team: not as sleek as the rookies, but still trusted when the game is serious. Their age, maintenance demands, and noisier design mean they are gradually being replaced. However, as long as some remain operational, they add depth to Russia’s deterrent force.

Nuclear Cruise Missile and Attack Submarines

If SSBNs are the nuclear insurance policy, Russia’s cruise missile and attack submarines are the sharp tools in the drawer. These boats are built to track enemy ships, threaten carrier groups, launch land-attack cruise missiles, and patrol far from home waters.

Yasen and Yasen-M Class

The Yasen class is widely considered the crown jewel of Russia’s modern attack submarine force. The original Severodvinsk was followed by improved Yasen-M boats such as Kazan, Novosibirsk, Krasnoyarsk, and Arkhangelsk. The Yasen-M design is shorter than the original but more refined, with modern sensors, stealth features, and a flexible missile loadout.

Yasen-M submarines can carry weapons such as Kalibr land-attack cruise missiles, Oniks anti-ship missiles, and potentially Zircon hypersonic missiles. That combination gives them a broad mission set: strike targets ashore, threaten naval groups, and operate as high-end hunter-killers. In plain English, they are the submarines NATO watches closely and politely does not underestimate.

The biggest limitation is production speed. These boats are expensive and complex. Russia has improved construction timelines compared with the painfully long build period of Severodvinsk, but replacing older submarines one-for-one with Yasen-Ms remains a major industrial challenge.

Oscar II Class

The Oscar II class, known in Russia as Project 949A Antey, is a Soviet-era cruise missile submarine built for a very specific Cold War mission: attack U.S. carrier strike groups. These are huge boats, originally armed with large anti-ship missiles. The infamous Kursk, lost in 2000, was an Oscar II.

Several remaining Oscar II submarines have been retained, upgraded, or considered for modernization. Some upgrades are intended to replace older missile systems with more modern Kalibr or Oniks missiles. The class is aging, but its size and missile capacity still make it useful, especially for Russia’s Pacific and Northern Fleets.

Akula Class

The Akula class is a nuclear-powered attack submarine designed for anti-submarine and anti-surface warfare. These boats were once among the Soviet Union’s most impressive undersea achievements, and some remain potent after modernization. Akulas can track enemy submarines, escort strategic missile boats, and operate in deep-ocean patrol areas.

However, age matters. The Akula fleet has faced maintenance delays, overhaul bottlenecks, and uneven readiness. A fully modernized Akula is still dangerous; an older one tied to the pier is, well, mostly dangerous to the maintenance budget.

Sierra and Victor III Classes

The Sierra class is unusual because of its titanium hull, which allows deep diving and gives it a unique place in Russian naval engineering history. Titanium submarines are impressive but expensive, difficult to maintain, and not exactly something you build casually on a Friday afternoon.

The Victor III class is older still. These submarines represent late Cold War Soviet attack-submarine design and are gradually fading from front-line relevance. Their continued presence in open-source counts is one reason Russian submarine totals can look large while actual combat-ready numbers may be smaller.

Diesel-Electric Submarines: Quiet, Regional, and Still Dangerous

Russia’s diesel-electric submarines are not glamorous in the nuclear sense, but they are extremely important. In confined waters such as the Black Sea, Baltic Sea, Mediterranean approaches, and parts of the Pacific, a quiet conventional submarine can be a serious headache.

Kilo and Improved Kilo Class

The Kilo class is one of Russia’s most successful submarine families. It has been exported widely and remains a major part of the Russian Navy. The Improved Kilo, especially Project 636.3, adds better sensors, quieter operation, and the ability to fire Kalibr cruise missiles from torpedo tubes.

This is what makes the Improved Kilo so important in modern conflicts. A relatively small diesel-electric submarine can sit in regional waters and launch long-range missiles at land targets. During the war in Ukraine, Russian Kalibr-capable submarines in the Black Sea became part of Moscow’s long-range strike network, though Ukrainian attacks and changing basing patterns complicated Russian operations.

The Kilo’s strength is stealth at low speed, especially in shallow or noisy waters. Its weakness is endurance. Unlike a nuclear submarine, a diesel-electric boat must manage battery life and eventually snorkel or return to port. Still, in the right environment, it is a very effective ambush predator.

Lada Class

The Lada class was intended to be the next-generation successor to the Kilo. In theory, it would be quieter, more automated, and better equipped for modern missions. In reality, the program has been delayed, revised, and slowed by technical problems. The lead boat, Sankt Peterburg, had a troubled career, while later boats such as Kronstadt and Velikiye Luki represent Russia’s continuing effort to make the design work.

Unlike some modern non-nuclear submarines, the Lada class does not currently appear to field a mature air-independent propulsion system. That matters because AIP can help conventional submarines remain submerged longer. Even so, Russia continues to invest in the class, likely because it needs a domestic replacement for older Kilos and wants a smaller, quieter submarine for coastal operations.

Special-Purpose Submarines: The Strange End of the Fleet

Every navy has a few unusual programs. Russia’s special-purpose submarine fleet takes that idea, adds nuclear propulsion, deep-sea engineering, seabed operations, and a dash of apocalypse branding. These boats are associated with intelligence missions, undersea infrastructure, and exotic weapons systems.

Belgorod

Belgorod is one of the most discussed Russian submarines in the world, partly because it is enormous and partly because it is associated with the Poseidon nuclear-powered underwater vehicle. Originally based on an Oscar II hull, Belgorod was modified into a special-purpose submarine capable of carrying large unmanned underwater systems and potentially supporting deep-sea missions.

Belgorod is often described as a “doomsday submarine,” which sounds dramatic because it is dramatic. The Poseidon concept is designed to bypass missile defenses by traveling underwater. Whether it becomes a fully reliable operational system at scale is another question, but even the idea changes how analysts think about undersea nuclear deterrence.

Khabarovsk

Khabarovsk is another special-purpose submarine associated with Poseidon. Unlike Belgorod, which was converted from an older hull, Khabarovsk appears to have been designed from the beginning around this unusual mission. Details remain limited, and open-source analysts continue to debate its exact capabilities.

What matters for the infographic view is that Khabarovsk and Belgorod represent a separate Russian undersea strategy: not just submarines that launch missiles, but submarines that deploy unmanned nuclear-powered underwater vehicles. That is a very different flavor of deterrence, and frankly, not the kind you want spilled on the carpet.

Why Russia Still Invests So Heavily in Submarines

Russia is a geographically complicated naval power. Its fleets are split among the Northern, Pacific, Baltic, Black Sea, and Caspian regions. Moving ships between theaters can be difficult, especially during war or political crisis. Surface ships are visible, vulnerable, and expensive to replace. Submarines, by contrast, offer stealth, survivability, and strategic reach.

The Northern Fleet is especially important because it protects Russia’s Arctic nuclear bastions and provides access to the North Atlantic. The Pacific Fleet matters because of Russia’s Far Eastern territory, its relationship with China, and the strategic waters around Japan and the wider Indo-Pacific. The Black Sea Fleet has been heavily affected by the war in Ukraine, making submarines and missile-capable smaller vessels more valuable for standoff strike missions.

Another reason submarines matter is prestige. For Moscow, advanced submarines are proof that Russia remains a great military power. A new Borei-A or Yasen-M commissioning ceremony is not just a naval event; it is a political message wrapped in steel, sonar, and national television.

What the Infographic Really Shows

An infographic of all Russian Navy submarines is more than a neat collection of silhouettes. It shows a fleet in transition. On one side are older Soviet designs: Delta IV, Oscar II, Akula, Sierra, Victor III, and original Kilos. On the other side are modern or modernizing programs: Borei-A, Yasen-M, Improved Kilo, Lada, Belgorod, and Khabarovsk.

The challenge for Russia is not imagination. Russian naval designers have imagination by the submarine-load. The challenge is production, maintenance, sensors, crew training, sanctions, electronics, and shipyard capacity. Building one impressive submarine is difficult. Building a balanced, deployable, maintainable fleet across multiple oceans is much harder.

That is why raw numbers can mislead. A country may list more than 60 submarines, but the key questions are: How many can deploy? How quiet are they? How modern are their weapons? How well trained are their crews? How many are stuck in overhaul? And how many are included in the count because nobody wants to admit they have become museum pieces with plumbing?

Experience Notes: Reading a Russian Submarine Infographic Like an Analyst

When you first look at a Russian Navy submarine infographic, the natural reaction is, “That is a lot of submarines.” The second reaction is usually, “Why do half of these names sound like they belong to different families?” That confusion is normal. Russian submarines are commonly identified by Russian project number, Russian class name, NATO reporting name, hull number, and sometimes a ceremonial ship name. One boat can therefore feel like five boats wearing different hats.

The best way to read the infographic is to start with mission, not name. Ask what the submarine is built to do. If it carries ballistic missiles, it belongs in the strategic deterrence category. If it carries cruise missiles and hunts high-value naval targets, it belongs with the Yasen or Oscar-type strike boats. If it is diesel-electric, think regional defense, chokepoints, coastal patrols, and missile launches from enclosed seas. If it carries unmanned systems or deep-diving vehicles, congratulationsyou have entered the special-purpose rabbit hole.

Another useful experience is to compare age with capability. Some older Russian submarines still look intimidating on paper, and some remain genuinely dangerous. But age affects everything: reactor life, acoustic quieting, sensors, wiring, crew comfort, and the ability to integrate modern weapons. A late Cold War submarine that has received major upgrades may be far more relevant than a newer-looking boat with unresolved technical problems.

It also helps to remember geography. A submarine in the Northern Fleet is part of a different strategic story than one in the Black Sea or Pacific Fleet. Northern Fleet submarines are tied to Arctic bastions, NATO monitoring, and nuclear deterrence. Pacific Fleet boats face Japan, the United States, and the wider Indo-Pacific theater. Black Sea submarines are constrained by geography and the Turkish Straits, but they can still launch long-range cruise missiles. Location changes the meaning of the same class.

Finally, treat every “all submarines” graphic as a snapshot, not a stone tablet delivered from Mount Naval Certainty. Submarines move in and out of overhaul. New boats are commissioned. Old boats are retired quietly. Wartime damage may be denied, exaggerated, or hidden. Open-source intelligence is excellent, but the ocean is large, dark, and extremely good at keeping secrets. The smart reader uses the infographic as a map, then reads the notes like a cautious navigator.

Conclusion

The Russian Navy’s submarine fleet is a mix of old steel and new ambition. Its modern Borei-A ballistic missile submarines strengthen Russia’s nuclear deterrent. Its Yasen-M cruise missile submarines give Moscow a high-end conventional and potentially nuclear strike platform. Its Improved Kilos remain useful regional predators, especially in enclosed seas. Meanwhile, special-purpose submarines like Belgorod and Khabarovsk point toward a stranger future of unmanned underwater weapons and seabed competition.

The infographic view makes one thing obvious: Russia may struggle with parts of its surface fleet, but underwater, it remains a serious naval power. The fleet is not flawless. It is uneven, aging in places, and limited by industrial bottlenecks. But it is also modernizing in the areas Moscow values most: nuclear deterrence, long-range strike, Arctic operations, and undersea disruption.

In short, Russian submarines are not just naval hardware. They are strategy in steel formquiet, complicated, expensive, and designed to make adversaries lose sleep. Which, for a submarine, is basically a performance review that says, “Excellent work.”
