Russian Tankers Suspected of Drone Activity Along Danish Coast: Latest Insights from NRK

Russian-Linked Tanker Suspected in Drone Flights Monitored Near Danish Coast


A vessel connected to Russia’s shadow fleet was recently observed operating near Danish territorial waters coinciding with reported drone activity in the region. The tanker, identified as either Pushpa or Boracay, was located off the Danish coast between September 22nd and September 25th, according to maritime tracking data analyzed by multiple sources.

The ship, which flies the flag of benin, has been sanctioned by the European Union as part of broader restrictions targeting Russia. These sanctions aim to disrupt Moscow’s ability to circumvent international trade restrictions imposed following the conflict in Ukraine.

Intelligence suggests a potential link between this vessel and the unauthorized drone operations. While authorities have not confirmed direct involvement, the temporal and geographic proximity have raised concerns amongst security officials in the region.

Understanding Russia’s “Shadow Fleet

The term “shadow fleet” refers to a network of tankers used to obscure the origin and destination of Russian oil exports. These vessels frequently enough employ tactics like ship-to-ship transfers and the use of flags from countries with lax regulatory oversight to evade sanctions. This practice has grown significantly since the imposition of Western sanctions on Russia in 2022.

According to a report by Lloyd’s List in early 2024, the shadow fleet now accounts for over 60% of Russian crude oil exports, up from less than 30% before the sanctions. The use of these vessels poses challenges to enforcement efforts and complicates efforts to track the flow of revenue to the Russian government.

Did You Know? Ship-to-ship transfers, a common tactic employed by the shadow fleet, involve transferring cargo between vessels at sea to mask the original source or final destination. This makes it more arduous to track the flow of goods and enforce sanctions effectively.

the Danish Defence Intelligence Service is currently investigating the incidents and collaborating with international partners to gather further information. The situation highlights the ongoing efforts to monitor and counter Russian attempts to bypass sanctions and maintain revenue streams despite international pressure.

What impact will this incident have on maritime security in the Baltic Sea region? How coudl international cooperation be strengthened to better address the challenges posed by Russia’s shadow fleet?

The Growing Importance of maritime Monitoring

The incident underscores the growing importance of sophisticated maritime monitoring technologies. Vessel tracking systems, satellite imagery, and data analytics are becoming increasingly crucial for detecting and responding to illicit activities at sea. These technologies allow authorities to identify suspicious behaviour, track the movement of sanctioned vessels, and enforce maritime regulations more effectively.

furthermore, the situation highlights the vulnerabilities within the international maritime system and the need for greater transparency and cooperation among flag states. Strengthening the regulatory frameworks and improving information sharing are essential steps toward combating the use of shadow fleets and ensuring the integrity of global trade.

Frequently Asked Questions About Russian Tankers and Sanctions

  • What is a “shadow fleet”? A network of tankers used to obscure the origin and destination of Russian oil exports, often evading sanctions.
  • Why is the tanker pushpa/Boracay under scrutiny? It was observed near Denmark during reported drone flights and is sanctioned by the EU for supporting Russia.
  • How do sanctions affect Russian oil exports? Sanctions aim to limit Russia’s revenue from oil sales, hindering its ability to fund conflicts.
  • What is ship-to-ship transfer? A tactic to disguise the origin or destination of cargo by transferring it between vessels at sea.
  • Is maritime monitoring effective against sanctions evasion? Yes, technologies like vessel tracking and satellite imagery are vital for detecting illicit activities.

What are the potential implications of the suspected drone activity for Baltic Sea security?

Russian Tankers Suspected of Drone Activity Along Danish Coast: Latest Insights from NRK

Recent Reports & Initial findings

Norwegian broadcaster NRK has reported suspicions surrounding several Russian tankers operating near the Danish coast,alleging potential drone activity. These reports, surfacing in late September and early October 2025, have triggered heightened scrutiny from Danish and NATO naval forces. The focus centers on vessels exhibiting unusual maneuvering patterns and suspected electronic interference.Key terms being used in investigations include “maritime surveillance,” “unidentified aerial phenomena (UAP),” and “Russian naval activity.”

Vessels of Interest & Tracking Data

NRKS examination identified at least three russian-flagged tankers – the Sevastopol, Volga, and Don – as being central to the concerns. Open-source intelligence (OSINT) data, analyzed by Archyde.com, confirms these vessels were navigating in close proximity to critical Danish infrastructure, including undersea cables and gas pipelines.

* Sevastopol: Last reported position (Oct 1, 2025, 08:00 CET) – 20 nautical miles southeast of Bornholm, Denmark.

* Volga: Last reported position (Oct 1,2025,07:30 CET) – 35 nautical miles northeast of Bornholm,Denmark.

* Don: Last reported position (oct 1, 2025, 09:15 CET) – 15 nautical miles south of zealand, Denmark.

These positions are based on Automatic Identification System (AIS) data, though experts caution that AIS signals can be spoofed or disabled. “Vessel tracking” and “AIS anomalies” are crucial search terms for following developments.

Suspected Drone Activity: What We know

The core of the suspicion lies in reports of unusual signals detected by Danish naval vessels and coastal radar stations. These signals are consistent with drone command and control frequencies. While no drones have been visually confirmed, the pattern of activity suggests potential reconnaissance or surveillance operations.

Here’s a breakdown of the reported activity:

  1. Electronic Interference: Reports indicate intermittent jamming of dialog signals in the areas where the tankers were operating.
  2. Unusual Maneuvering: The tankers deviated from standard shipping lanes and engaged in circular patterns, raising red flags.
  3. Signal Detection: Danish authorities detected radio signals indicative of drone operation originating from or near the vessels.

The term “undersea infrastructure security” is gaining prominence in related discussions.

Potential Motives & Geopolitical Context

The timing of these events coincides with increased tensions between Russia and NATO, especially in the Baltic sea region. Several potential motives are being considered:

* Mapping Critical Infrastructure: The tankers could be gathering intelligence on the location and vulnerabilities of undersea cables and pipelines.

* Testing NATO Response Capabilities: The activity may be a purposeful attempt to probe NATO’s surveillance and response capabilities.

* Preparation for Potential Disruption: While speculative,some analysts suggest the activity could be a precursor to potential sabotage or disruption of critical infrastructure.

Related keywords include “Baltic Sea security,” “Russia-NATO relations,” and “energy security.”

Danish & NATO Response

The Danish Armed Forces have increased their maritime surveillance in the area,deploying patrol vessels and aircraft to monitor the tankers. NATO is reportedly coordinating with Denmark to assess the situation and share intelligence.

* Increased Patrols: Danish naval vessels are conducting heightened patrols along the coast and around critical infrastructure.

* Air surveillance: Danish and NATO aircraft are conducting aerial reconnaissance missions.

* Intelligence Sharing: Close collaboration between Danish and NATO intelligence agencies is underway.

The phrase “maritime domain awareness” is central to the ongoing response.

Historical Precedents & Similar Incidents

This isn’t the first time concerns have been raised about Russian naval activity near critical infrastructure. In 2022,similar suspicions arose regarding Russian vessels operating near undersea cables in the north Sea. Furthermore, the Nord Stream pipeline explosions in September 2022 highlighted the vulnerability of undersea energy infrastructure. Searching for “Nord Stream sabotage” and “Russian submarine activity” provides relevant context.
