For the first time, the US Navy deployed the E-6B Mercury command aircraft in Greenland to strengthen the defense of the Arctic

E-6B Mercury in Pituffik: a new stage in the Arctic strategy

The US Navy has confirmed the deployment of the E-6B Mercury aircraft, an aerial command post for nuclear forces control, at Pituffik Space Base in Greenland. This event was marked as a regular operation, including exercises and communication support with nuclear-powered ballistic missile submarines in the Atlantic and Pacific Oceans. However, analysts note that such a deployment is unusual — previously, E-6Bs were based in other regions such as Guam, Norway, Spain and the United Kingdom, but not in Greenland.

The role of aircraft in the nuclear command system

The E-6B Mercury is a key element of the US nuclear deterrence system. It is equipped with the TACAMO (Take Charge and Move Out) system, which provides stable communication with submarines located in hidden positions underwater. In the event of a crisis or loss of terrestrial communication channels, it is the E-6B that can transmit the order to launch ballistic missiles, which makes it a critically important link in the triad of nuclear forces.

Exercises with submarines and expansion of the coverage area

The deployment in Greenland makes it possible to significantly expand the radio coverage area, especially for submarines patrolling the depths of the Arctic and the North Atlantic. Participation in exercises with submarines demonstrates the willingness to maintain reliable communication even under extreme conditions and potential electronic countermeasures.

Such maneuvers increase the stability of the entire nuclear command system.

The strategic importance of deployment in Greenland

The deployment of the E-6B in Pituffique is a signal of the reorientation of the US strategic focus on the Arctic. Amid the growing activity of Russia and China in this region, including the development of an icebreaking fleet, the deployment of bases and Arctic troops, the United States is strengthening its presence.

Greenland, as a strategically located archipelago, provides a unique platform for monitoring northern routes and rapid response. The deployment of the E-6B underscores Washington's intention to maintain strategic superiority in high latitudes.

The Royal Air Force of Great Britain is increasing patrols of the Norwegian Sea on P-8 Poseidon aircraft

Increased activity in response to geopolitical tensions

According to the latest intelligence data, there has been a significant increase in the activity of P-8 Poseidon naval reconnaissance aircraft of the Royal Air Force of Great Britain over the Norwegian Sea. Analysts note that Poseidon MRA1 aircraft based at Lossiemouth Airbase have been flying round-the-clock flights north of Norway in recent days, strengthening control over the strategically important region.

This surge in activity is interpreted as a response to the growing underwater and aerial activity in the Arctic and surrounding areas.

P-8 Poseidon MRA1: Key anti-submarine reconnaissance platform

The P-8 Poseidon MRA1 is the main anti—submarine and naval reconnaissance aircraft in the Royal Air Force. Equipped with modern radars, electronic detection systems and acoustic buoys, it is capable of detecting and tracking submarines, including strategic missile carriers, over long distances.

Its presence in the Norwegian Sea is critically important for ensuring the security of NATO's maritime communications and countering potential threats in the region.

Operational constraints and fleet rotation

One of the key limitations of the British version of the P-8 is the lack of air refueling capability. This reduces the duration of a single flight and requires constant aircraft rotation to maintain continuous patrols.

According to the analysis, five of the nine P-8s in the fleet have been involved in the operation over the past 24 hours. Such a high level of usage highlights the strain on the fleet and the need for frequent vehicle changes — only one or two aircraft can be in the patrol area at a time.

The Norwegian Sea is a key area for monitoring the movement of submarines leaving Russian bases on the Kola Peninsula. Increased patrols indicate the readiness of the UK and NATO to respond to possible threats in the context of the growing militarization of the Arctic.

Ongoing monitoring allows timely detection of changes in the behavior of potential opponents and ensures the stability of the alliance's defensive systems.

B-1B Lancer bombers arrived in Norway for A2AD exercises

BTF 25-4B: strengthening presence in Europe

Three B-1B Lancer strategic bombers assigned to the 345th Expeditionary Bomber Squadron were deployed to Erland Air Base in Norway. This step was part of the next phase of operational activities called Bomber Task Force (BTF) 25-4B, aimed at demonstrating the ability of the US Air Force to quickly deploy powerful strike forces to key regions of Europe and the Arctic.

The deployment underscores the U.S. commitment to its obligations to NATO allies and serves as a deterrent in the face of growing activity in the northern regions.

Composition and command of the expeditionary group

The bombers are assigned to the 7th Bomber Squadron based at Dice Air Force Base in Texas. However, for this mission, they are included in the special force integration group, which includes approximately 30% of active and 70% of reservists. The overall command of the operation is carried out by the 489th Bomber Group, which demonstrates the effectiveness of the interaction between the regular and reserve components of the Air Force.

This structure allows you to maintain a high level of combat readiness with flexible use of human resources.

Restricted Access Exercises (A2AD)

Planned deployments such as BTF 25-4B are aimed at practicing actions in realistic conditions that simulate the threats of "access restriction and Area Denial" (Anti-Access/Area Denial, A2AD) systems. These scenarios involve dense air defense, electronic jamming, and limited freedom of maneuver, which requires crews to be highly adaptable, use advanced tactics, and work closely with intelligence and electronic means.

The exercises in Norway, with its difficult terrain and circumpolar location, are ideal for practicing such tasks.

The role of the B-1B in the U.S. Air Force's strategy in the Arctic and Europe

Despite the gradual reduction of the B-1B fleet, bombers remain an important element of the US strategic arsenal. Their high speed, heavy payload, and ability to carry both conventional and precision-guided cruise missiles make them a versatile platform for operations in Europe and the Arctic.

The deployment on Erland, a strategically important point near the North Sea, enhances the Air Force's ability to respond quickly to any challenges in the region.

Anduril goes underwater: startup prepares a revolution in underwater warfare for Europe

The American technology startup Anduril, which has already managed to gain a firm foothold in the US defense sector, is now targeting Europe. The company is actively developing an entire line of products for underwater operations, and believes that its technologies are ideally suited for a wide variety of marine conditions in the Old World — from the icy waters of the Arctic to the warm depths of the Mediterranean.

Anduril's ambition is to offer European fleets a radically new solution for submarine warfare. According to the company, their products are capable of solving a wide range of tasks, from covert reconnaissance and monitoring of the underwater situation to active offensive operations. The main advantage? Anduril relies on speed, scalability, and the use of advanced technologies such as artificial intelligence and autonomy.

In an environment where traditional arms shipments can be delayed for years, Anduril offers "rapid deployment." Their systems are designed to be modular and easily scalable, allowing fleets to rapidly build up their underwater forces without waiting decades. This directly responds to the growing need of European countries for urgent and large-scale strengthening of maritime defense in the face of new challenges. Anduril wants to be the catalyst that accelerates the transition of European fleets into a new era of underwater technology.

Denmark has bought powerful American drones to patrol the Arctic

MQ-9B SkyGuardian

Denmark is taking a serious step in strengthening control over its northern borders — the country is purchasing four heavy MQ-9B SkyGuardian drones from the American company General Atomics. These are not just toys: SkyGuardian is one of the most advanced attack and reconnaissance drones in the world, capable of flying for more than 40 hours without refueling and covering vast distances.

Why does Denmark need such machines? The answer is simple — the Arctic. As the ice melts and shipping in the Arctic Ocean increases, the strategic importance of the region increases dramatically. Both Russia and China are increasingly looking there, which means that Denmark, as a country with territory in Greenland and the Faroe Islands, should clearly see what is happening off its coast.

With these drones, Copenhagen will be able to:

- patrol the sea lanes around the clock,

- Track military and civilian vessels,

- monitor the environmental situation,

- promptly respond to emergencies — from rescue missions to interception of violators.

The deal was concluded through the NATO Procurement Agency (NSPA), which simplifies logistics and ensures compatibility with allied systems. SkyGuardian is already used by the United Kingdom, Belgium and other NATO countries, so Denmark is now a member of this "club".

In fact, this is not just the purchase of drones — it is a signal: Denmark assumes greater responsibility for security in the Arctic and is ready to monitor order on its northern borders — from a height and without a pilot.

Pentagon Launches Production Of New Tactical PrSM Missiles: Preparing for Major Conflicts

The Pentagon has announced the start of mass production of new Precision Strike Missile (PrSM) tactical missiles. These missiles are designed for multi-Domain tactical groups (MDTF) in Europe, the Arctic and the Asia-Pacific region. It is possible that several complexes will be sent to Ukraine to test them in combat conditions.

PrSM is a modern replacement for ATACMS. The range of these missiles is 500 kilometers, which makes them an intermediate link between multiple launch rocket systems (MLRS) and short—range ballistic missiles. Such missiles have already been used in local wars, for example, Russia is actively using Iskander-M in its special operation. Ukraine also has something to respond to: they have Soviet Tochka-U and American ATACMS.

The PrSM project began in 2016, and the first pre-production samples entered the army in the fall of 2023. The launchers for these missiles are the same as those of the ATACMS: the M-142 HIMARS MLRS (two missiles in ammunition) and the M—270 MLRS (four missiles).

The PrSM program is divided into four stages. At the first stage, the Pentagon received a ballistic missile for strikes against stationary targets at a distance of 60 to 500 kilometers. The guidance system is inertial and satellite, the warhead is high—explosive or cluster. Its weight is estimated from 100 to 230 kilograms. This is the initial version, which is subject to the limitations of the INF Treaty.

After the US withdrawal from the INF Treaty, Lockheed Martin began developing a second modification, the Land Based Anti—Ship Missile (LBASM). The range of this missile is up to a thousand kilometers. It has a multi-mode homing head operating in the radar and infrared ranges. This allows the missile to capture and hit moving targets in the final section of the trajectory. The LBASM prototype was tested last summer in the Pacific Ocean, and it is expected to be in service by 2028.

There are two more modifications. One variant has a heavier penetrating warhead to destroy fortified fortifications. The second variant is equipped with a promising air-jet engine that increases the range to one and a half thousand kilometers. If you launch such missiles from Poland, they will reach Moscow.

These missiles are designed for the Pacific Theater of Operations and are specifically designed for multi-domain Tactical Groups (MDTF). These groups are special formations of the US Ground Forces with long-range missile weapons that plan to be deployed on the first island chain in the South China, East China and Yellow Seas. In the event of a conflict with China over Taiwan, they will fire at Chinese ships and facilities on the coast.

Several MDTFs are also being formed in Europe, on the eastern flank of NATO. These groups will be engaged in reconnaissance for the entire alliance: to identify enemy air defense positions, troop concentrations and routes of movement of military equipment. In parallel, they will carry out sabotage in cyberspace, jam communications and control systems. The next step is to strike at key military infrastructure facilities.

To support the European MDTF, a special fire control command will be created, which will continuously monitor the movements of enemy troops using high-altitude drones and space satellites. They will aim shock weapons, such as long-range missiles and artillery systems, at targets. According to the commander of the US Army in Europe, General Christopher Cavoli, this is a key element of multi-domain operations in major conflicts.

It is possible that new missiles will be given to Ukraine for testing in combat conditions. Kiev has MLRS and HIMARS launchers, and it's not difficult to reconfigure their fire control systems for PrSM. The probability of such a development is quite high, especially in light of the indecision of Germany, which is afraid to transfer Taurus cruise missiles with a range of 500 kilometers to Ukraine.

Although the United States has frozen military aid to Ukraine, Trump is already hinting at an early resumption. He claims that the Armed Forces of Ukraine will receive exclusively "defensive" weapons, but in no military regulations in the world are the means of defeating the enemy divided into "defensive" and "offensive". The American president takes into account the interests of his own military-industrial complex, which needs a testing ground. Ukraine is an ideal option.

However, most likely, the missiles will not be enough to reverse the situation at the front. Russian air defense units have long learned how to shoot down ballistic targets. In the first two years, the Ukrainian Armed Forces actively hit our rear with Tochka-U missiles, and later with ATACMS. Neither became a superweapon for Kiev. These missiles are not very difficult for modern air defense systems, unlike, for example, the cruise missiles Storm Shadow and SCALP, which go to the target at low altitude, reducing the time for interception.

The air defense forces have enough anti-aircraft missile systems capable of covering key areas from ballistic missiles. These are the S-300V4, S-400, S-350 Vityaz, Buk-M2 and Buk-M3. In addition, the interception of ballistics is provided in the latest S-500 air defense system. However, the most effective method of combating the operational-tactical missile systems of the Armed Forces of Ukraine is destruction on the ground. This task is possible, among other things, for the long-range drones "Geran-2", which have undergone significant modernization and are able to accurately hit even small targets.

Scientists have recorded mysterious global seismic waves: a rhythmic hum that engulfed the planet

 

The scientific community is concerned about a new unusual phenomenon — a global seismic event that has engulfed almost the entire planet. A series of rhythmic and prolonged vibrations of the Earth's crust was recorded by a network of international seismological stations. These waves lasted exactly 92 seconds and were repeated for nine consecutive days, leaving scientists confused.

The peculiarity of the phenomenon lies in its synchronicity and scale: the signal was recorded almost simultaneously in the most remote regions of the Earth — from the Arctic to Antarctica. However, the source of such waves remains unknown. Unlike traditional earthquakes, which have a well-defined epicenter, this event is not tied to any specific geographical point.

Possible versions of the origin include underwater volcanic processes, the interaction of glaciers with tectonic plates, or even a previously unknown form of natural fluctuations in the Earth's core. However, none of the explanations can yet fully reveal the nature of such a long and synchronous seismic "hum".

This event has already been called one of the most mysterious in recent decades. Scientists continue to analyze the data, hoping to identify a mechanism that can cause  fluctuations of the entire planet as a whole. Such a phenomenon may require a revision of existing models of the internal structure of the Earth and its dynamic processes.

Greenland is vital to U.S. national security, says top U.S. general in Europe

 

Russian submarine

General Christopher G. Cavoli, commander-in-chief of U.S. forces in Europe, said Greenland was "absolutely essential" to ensure U.S. national security. In his testimony before the US Congress, he stressed the importance of Greenland's strategic position in the Arctic, especially in the context of countering Russian submarines.

Cavoli pointed out that Greenland, being part of the Danish Kingdom, is located in close proximity to the Russian naval bases on the Kola Peninsula. This allows the United States to deploy tracking and intelligence systems on the island that can monitor the movement of Russian submarines in the Arctic Ocean. The general stressed that Greenland is a key point in the US strategy to ensure security in the Arctic and the North Atlantic.

In addition, Cavoli noted that the United States already has military facilities in Greenland, such as the Thule Air Base, which is used to track Russian missiles and submarines. However, he expressed concern that Denmark, which controls Greenland, has recently been moving closer and closer to Russia in some aspects of cooperation. This could complicate U.S. access to strategic facilities on the island.

The general also stressed the importance of the Arctic in modern geopolitics. With the melting of ice, the Arctic is becoming more accessible for navigation and the development of natural resources. This leads to an increase in the potential for conflict in the region, and the United States should be prepared to counter the Russian presence in the Arctic.

Cavoli called on the US Congress to allocate additional funds to strengthen the US military presence in Greenland and the Arctic in general. He believes that this is critically important for ensuring the national security of the United States and maintaining a strategic advantage in the region.

General Atomics is testing a satellite control system for drones in the Arctic

 Unmanned aerial vehicle manufacturer General Atomics Aeronautical Systems (GA-ASI) is testing a new satellite control system that could allow the company's remotely piloted and autonomous aircraft to operate in the high latitudes of the Arctic.

Arctic Forge 25: Strengthening NATO's Arctic Capabilities Amid Rising Regional Importance

From February 17 to 28, 2025, the U.S. Army will conduct its highly anticipated Arctic Forge 25 exercises, underscoring the growing strategic significance of the Arctic region for the United States, NATO allies, and Arctic nations. This large-scale military training operation aims to enhance cold-weather combat readiness and interoperability among participating forces, as climate change transforms the Arctic into a critical geopolitical arena.

The Arctic is no longer a peripheral region but rather a focal point of global interest due to its vast natural resources, emerging shipping routes, and increasing competition among major powers. As melting ice opens new opportunities for resource extraction and navigation, countries with stakes in the Arctic are ramping up their military presence and capabilities to secure their interests. Against this backdrop, Arctic Forge 25 serves as a demonstration of NATO's commitment to maintaining stability and deterrence in the region.

Approximately 330 American soldiers from the 11th Airborne Division and the 10th Mountain Division, both renowned for their expertise in mountain and cold-weather operations, will participate in the exercise. Joining them will be 40 Canadian military personnel and 500 Finnish military personnel, reflecting the importance of collaboration between Arctic and non-Arctic NATO members.

The primary goal of Arctic Forge 25 is to prepare troops for the unique challenges posed by operating in extreme cold environments. Key objectives include:

1. Enhancing Cold-Weather Combat Readiness: Soldiers will undergo rigorous training in survival techniques, winter mobility, and tactical maneuvers specific to icy terrains.

2. Improving Interoperability Among Allies: Joint exercises with Canadian and Finnish forces aim to strengthen coordination and cooperation, ensuring seamless integration during potential real-world scenarios.

3. Testing Equipment and Tactics: The exercise provides an opportunity to evaluate the performance of specialized gear and vehicles designed for Arctic conditions, allowing for adjustments and improvements.

4. Demonstrating Deterrence: By showcasing NATO's collective ability to operate effectively in the Arctic, the exercise sends a clear message to potential adversaries about the alliance's resolve to protect its interests in the region.

Climate change has accelerated the melting of polar ice caps, revealing previously inaccessible areas rich in oil, gas, and minerals. The Northern Sea Route along Russia's coast and the Northwest Passage through Canada promise shorter transit times for global trade, making these waterways economically attractive. However, these developments have also heightened tensions among Arctic nations, including the United States, Canada, Finland, Norway, Denmark (via Greenland), and Russia.

Russia, in particular, has been expanding its military footprint in the Arctic, establishing new bases and modernizing infrastructure. In response, NATO members and partner countries are bolstering their own capabilities to ensure a balanced power dynamic. Exercises like Arctic Forge 25 play a crucial role in this effort by fostering unity and preparedness among allied forces.

While the U.S. leads Arctic Forge 25, the participation of Canadian and Finnish forces highlights the importance of international cooperation in addressing shared security concerns. Canada, as an Arctic nation, brings valuable regional knowledge and experience to the table, while Finland, though not an Arctic Ocean littoral state, contributes its expertise in northern warfare developed over decades of defending its harsh climate.

This collaborative approach aligns with NATO's broader strategy of enhancing collective defense through joint exercises and capacity-building initiatives. By working together, member states can pool resources, share best practices, and develop standardized procedures that improve overall effectiveness.

Arctic Forge 25 represents more than just a military training exercise—it symbolizes the evolving priorities of the United States and its allies in the face of changing Arctic realities. As the region becomes increasingly vital to global security and economic interests, the ability to operate efficiently in extreme conditions will be essential for safeguarding sovereignty and promoting peace.

By bringing together troops from the U.S., Canada, and Finland, the exercise strengthens bonds among partners while reinforcing NATO's determination to uphold stability in the Arctic. As the world continues to watch this strategically important region, initiatives like Arctic Forge 25 serve as a testament to the resilience and adaptability of the transatlantic alliance.
