Northern Fleet: Guardians of Russia’s Arctic Frontiers and Deterrence Force


Saturday marks the official holiday of the Northern Fleet, Russia’s formidable naval grouping responsible for protecting the nation’s Arctic frontiers and ensuring a significant part of the maritime component of its nuclear triad. The Northern Fleet’s legacy dates back to the era of Czar Peter the Great, who initiated Russia’s venture into the icy waters of the north by establishing the first naval base in Arkhangelsk in 1733. The fleet, in its modern form, was established on June 1, 1933, as the Northern Military Flotilla and was upgraded to fleet status in 1937.

Over nearly 300 years, the Northern Fleet has been pivotal in Russia’s defense, playing crucial roles in both World Wars, standing up to US armadas during the Cold War, and currently serving as a bulwark against NATO amidst the proxy conflict in Ukraine.

A Formidable Force

Sharing the title of the most powerful Russian naval formation with the Pacific Fleet, the Northern Fleet’s mandate goes beyond conventional defense. It provides assured deterrence against nuclear aggression with its fleet of nearly undetectable nuclear submarines, capable of launching devastating retaliatory strikes even in the event of an enemy’s first strike.

The fleet’s impressive arsenal includes over 70 surface warships and submarines, such as Russia’s only aircraft carrier, the Admiral Kuznetsov, missile cruisers, destroyers, frigates, minesweepers, landing ships, patrol vessels, strategic missile submarines, and cruise-missile-armed submarines, both nuclear and diesel-powered. Additionally, it operates over a dozen support ships, including tankers, floating repair bases, search and rescue vessels, hospital ships, reconnaissance vessels, and the 6,000-ton Ilya Muromets heavy-duty icebreaker.

Modernization and Strategic Importance

Given the increasing strategic importance of the Arctic, heightened by warming temperatures and the creation of the Northern Sea Route, the Russian state has prioritized the Northern Fleet for the deployment of many of its newest warships and submarines.

In late December 2023, the 5,400-ton Admiral Gorshkov-class Admiral Golovko frigate joined the fleet, equipped with vertical launch cells for Oniks, Zircon, and Kalibr missiles, Redut air defenses, Palash close-in weapon systems, and 330 mm tubes for the new Paket-E/NK torpedo. In 2022, the Belgorod, a new drone mothership submarine derived from the Project 949A Antey series, was added to the fleet, carrying 4-6 Poseidon nuclear drones capable of causing tsunamis. Later in 2024, the Borei-A-class strategic missile submarine Knyaz Pozharskiy is expected to join, adding to the fleet’s strategic capabilities.

APPENDIX 1 – Unveiling Russia’s Poseidon: The Nuclear Torpedo Shaping Modern Warfare

In January 2023, the Russian news agency TASS reported that Russia had produced the first set of nuclear-powered, very long-range, nuclear-armed torpedoes known as “Poseidon.” Strategic experts are warning that the Poseidon torpedo has the potential to devastate a coastal city, cause radioactive floods, and result in millions of deaths. Over the past few years, tabloid news outlets have painted a hauntingly vivid picture of a towering, 1,000-foot-tall radioactive tsunami violently crashing onto British shores, pulverizing everything in its path, and transforming whole cities into barren, lifeless lands.

The Reality Behind Poseidon

Is Poseidon even real? In ancient Greek mythology, Poseidon was revered as the god of the oceans, protector of sailors, and those who worked or traveled at sea. In the current context, “Poseidon” takes on a different meaning, with a destructive weapon capable of causing catastrophic events. Russia’s Poseidon—also known in the United States as Kanyon, Ocean Multipurpose System, and Status-6—was first revealed by the Russian Navy in 2015 and reportedly tested for the first time in November 2016. The torpedo—a nuclear-powered underwater drone equipped with nuclear weapons—is designed to be launched from submarines. The first Poseidon is expected to be deployed by 2027.

Technological Marvel or Propaganda Tool?

There is buzz that this new weapon is poised to shake the landscape of modern warfare. And this may owe less to its borrowed name than to some unmatched features—at least on paper. Powered by a compact nuclear reactor, it is believed the Poseidon could travel at unprecedented speeds of 100 knots (185 kilometers per hour), have a range of approximately 10,000 kilometers, and operate at depths of up to 1,000 meters. Designed to evade detection by acoustic tracking devices and other traps, the Poseidon has a diameter of approximately 1.6 to 2 meters. Particularly riveting is the torpedo’s devastating payload: a nuclear warhead with a likely yield of at least several megatons (with early reports suggesting it could yield up to 100 megatons). For comparison, Russia’s Tsar Bomba—the most powerful nuclear weapon ever tested—had an estimated blast yield of about 50 megatons.

While some reports claim that Russia’s Poseidon may exist only as a propaganda scheme, experts generally agree that the system is “very real” and has received significant resources from the Russian armed forces, although many details remain unknown. Intelligence reports have suggested that Poseidon has undergone many trials, evidenced by the fact that some submarines have been modified and some are being specially built to accommodate the larger and heavier Poseidon. For instance, the Sarov submarine is believed to have been modified to test Poseidon prototypes. According to TASS, the Russian Navy intends to purchase at least 30 Poseidon torpedoes and deploy them on four submarines.

Historical Context and Development

Poseidon’s origin and roles trace back to the mid-20th century. The idea of torpedoes fitted with a nuclear warhead was first conceived in the 1950s when the Soviet Union began two separate programs to develop submarine-launched nuclear torpedoes—the T-5 and the T-15. These programs were part of a broader strategy to expand the Soviet Union’s nuclear capabilities and gain an edge in a nuclear crisis. In October 1962, during the Cuban Missile Crisis, a Soviet submarine armed with a T-5 nuclear-tipped torpedo came close to launching it against US forces because its commander, Valentin Savitsky, believed that a US-Soviet Union war had already started. It is only because the submarine’s deputy commander, Vasili Arkhipov, convinced other top officers that launching the torpedo would be a fatal mistake that a potential nuclear catastrophe was prevented.

The Poseidon torpedo, however, will have no human onboard to make critical decisions after it has been launched. It will be controlled through a combination of remote communications and onboard automation. These forms of guidance may lead to problems that include hacking by third parties, loss of control because of technical malfunctions, and environmentally caused accidents that may lead to wrong signaling and thus inadvertent escalation.

Strategic Significance

The Poseidon can be viewed as an evolution in Russia’s nuclear deterrence strategy. Russia currently possesses the Dead Hand, an automated nuclear weapons command system also known as the Perimeter. Established during the Cold War, the Perimeter was created to ensure that, in a crisis, the Soviet Union could respond to a nuclear first strike, even if Russia’s armed forces were destroyed and all its leadership was eliminated. But with the technological advances of US ballistic missile defense systems, the Russian Perimeter system, which concerns intercontinental ballistic missiles only, has lost its preeminence.

Russian authorities describe the Poseidon torpedo as a multi-purpose system, suggesting that it could serve several roles. It is widely speculated that the Poseidon may have been developed as a reaction to advances in US ballistic missile defense capabilities. In March 2018, Russian President Putin stated that Poseidon and other advanced weapons were developed because of the demise of the 1972 US-Soviet Anti-Ballistic Missile Treaty, which Putin said was “the cornerstone of the international security system.” After the United States pulled out of the treaty in 2002 to build its new national missile defense system, Russia started working on improving their military equipment and weapons to maintain a strong nuclear deterrent capability against US assets.

Russia’s Nuclear Doctrine and Strategy

Besides being touted as a weapon that can circumvent US ballistic missile defenses for use against aircraft carrier groups and coastal targets, Poseidon also reflects Russia’s larger nuclear strategy and doctrine. After the Cold War ended, the United States shifted its focus to de-emphasizing the role of nuclear weapons in its security strategy. But Russia continued to greatly rely on nuclear weapons and even adopted a nuclear doctrine of “escalate to de-escalate,” which consists of using nuclear coercion and messaging tactics to achieve strategic goals. The development and deployment of new nuclear weapons like the Poseidon are considered to contribute to Russia’s broader strategy.

Strategic Stability and Technological Advances

Advances in artificial intelligence and the use of autonomous platforms for nuclear delivery such as unmanned aerial vehicles, unmanned underwater vehicles, and hypersonic glide vehicles have raised concerns over potential negative impacts on strategic stability. Weaker nuclear-armed countries would remain unable to keep up with progress in AI technologies, which also pose new risks by reducing the direct human control over nuclear weapons use. In this context, the deployment by Russia of its nuclear-capable, autonomous Poseidon torpedo could be seen to also threaten strategic stability.

However, many experts and US officials—including former US Defense Secretary James Mattis—believe that the addition of the Poseidon torpedo to Russia’s nuclear arsenal would not alter the existing strategic nuclear balance with the United States because Russia already possesses the capability to launch nuclear-armed missiles at US cities. The introduction of Poseidon would not significantly increase the existing threat and, even if used, its impact would be limited to coastal areas.

Psychological Weapon or Real Threat?

Instead, many see Poseidon primarily as a psychological weapon intended for nuclear signaling rather than for its actual use. Some even speculate that the Poseidon will remain at the prototype stage and serve mainly political objectives, such as renewed talks with the United States on ballistic missile defense systems. The weapon’s primary intent may be in the uncertainty, speculation, and fear it can provoke.

Response and Implications

Automated weapons like Poseidon, especially if controlled by artificial intelligence, undoubtedly add complexity to decision-making in a crisis. It effectively transforms AI into an active participant during times of strategic adversity. This has sparked a heated debate on whether these systems should be fully automated or not, as automation brings significant risks of misjudging the intentions of an opponent. To better understand the challenges posed by unmanned automated nuclear vehicles like Poseidon, further research is imperative, which requires gathering more information about the weapon itself.

While ensuring that research in automation only aims to reduce any risks associated with accidents or inadvertent use, it is equally important for countries to continue engaging in arms control and risk reduction talks whenever possible. Such dialogues may play a crucial role in providing insight into each other’s nuclear forces, helping to alleviate uncertainties about possible new weapon systems, including the Poseidon.

Updated Information and Data (June 2024)

As of June 2024, new developments have surfaced regarding the Poseidon torpedo. Reports from Russian defense agencies indicate that further trials and tests have been conducted, demonstrating improved operational capabilities. Satellite imagery and intelligence assessments suggest that Poseidon-equipped submarines have been observed in strategic positions within Russian naval bases.

Recent data highlights the Poseidon’s advancements in stealth technology. Enhanced acoustic quieting systems and advanced hydrodynamic designs have been incorporated to minimize detection risks. These improvements are expected to enhance Poseidon’s survivability against modern anti-submarine warfare systems.

Moreover, the payload capacity of the Poseidon has been a subject of intense scrutiny. Updated intelligence reports suggest that the yield of the nuclear warhead may vary depending on mission requirements. The torpedo could be configured with multiple warhead options, ranging from lower-yield tactical nukes to high-yield strategic warheads. This flexibility allows the Poseidon to be utilized in a variety of strategic scenarios.

Economic and Strategic Impact

The development and deployment of the Poseidon torpedo have significant economic implications for Russia. The investment in advanced nuclear-powered unmanned systems reflects a broader trend of modernization within the Russian military-industrial complex. Analysts estimate that the Poseidon project has cost billions of rubles, contributing to the economic activity in related sectors such as submarine construction, nuclear reactor technology, and advanced materials engineering.

Strategically, the Poseidon torpedo reinforces Russia’s nuclear deterrence posture. The capability to deploy a stealthy, long-range, autonomous underwater vehicle capable of delivering a nuclear payload adds a new dimension to Russia’s strategic arsenal. This enhances its second-strike capability, ensuring that even in the event of a significant first strike, Russia retains the means to inflict unacceptable damage on an adversary. This development aligns with Russia’s broader strategic objectives, emphasizing deterrence and the projection of power on a global scale.

Strategic Posture and Global Reactions

The introduction of Poseidon into the global strategic environment has prompted reactions from various international actors. NATO and the United States, in particular, have expressed concerns over the destabilizing potential of such a weapon.
