Rising Coca Demand Boosts Atlantic Route

The seizure of 41 tons of cocaine confirms Europol’s warning: the Atlantic route is at unprecedented levels

A record haul of 41 tons of cocaine, captured in two Guardia Civil operations within fifteen days, validates the alert issued by Europol at the start of 2026 about a drug influx of historic magnitude. The most striking episode was the interception of 30 tons aboard the vessel “Arconian” in early May, the largest single seizure in the fight against narcotrafficking.

Spain as the Epicentre of the Atlantic Corridor

Europol’s report identified the Atlantic corridor as positioning Spain at the heart of cocaine entry from Latin America, highlighting the Canary Islands and the Guadalquivir River as key entry points. Criminal networks employ:

• Mother ships stationed off the African coast
• Semi‑submersibles and “narcolanchas” (high‑speed speedboats)
• Sophisticated encrypted communications and armed escorts

Operation “Abyssal” – The Arconian Capture

On 1 May, the Central Operative Unit (UCO) detected the Arconian south of the Canary Islands during “Operation Abyssal”. The ship carried 30 215 kg of cocaine packed in 1 279 bales, marking the largest seizure ever recorded. Authorities detained the 23‑member crew, linked to the Mocro Mafia, who were also armed with assault rifles and 2 000 L of gasoline stored in 2 108 canisters intended for distribution to the narcolanchas that would rendezvous with the Arconian in the Mediterranean Sea.

Between 13 – 26 April, the Guardia Civil participated in an international operation that resulted in:

• 54 arrests
• Seizure of nearly 11 tons of cocaine
• 8.5 tons of hashish
• Over 30 000 L of fuel

“Black Shadow” Operation

Europol also cited the “Black Shadow” operation, carried out by the Udyco unit of the National Police. This crackdown targeted an Atlantic‑based network and led to 105 arrests, described as the largest attack on the distribution and money‑laundering hub of the Campo de Gibraltar. More than 10 tons of cocaine and 30 vessels were seized in two phases.

“Cocaine trafficking to Europe has reached unprecedented levels, driven by high production in Latin America and growing demand in the European Union,” the agency warned in its ‘Diversification of Maritime Cocaine Trafficking’ report, consulted by Europa Press.

The report urges greater international cooperation, noting that criminal groups are fragmenting and adopting complex, covert trafficking methods.

Infrastructure at Sea

Europol highlighted that traffickers are shifting away from commercial ports, opting for smaller vessels, high‑sea transshipments, and ingenious concealment tactics. Typical operations involve:

• A mother ship from Latin America transferring cocaine to a subsidiary vessel off West Africa.
• Use of advanced technologies: encrypted communications, autonomous vessels, and drones.
• Offloading in West Africa before forwarding the cargo to continental Europe or the Canary Islands.
• Once on the Andalusian coast, the drug is moved inland via the Guadalquivir River.

These networks also employ inflatable boats capable of remaining at sea for up to 100 nautical miles for extended periods and are willing to use violence, proliferating the presence of weapons on these shipments.

High‑Speed Narcolanchas

The “Black Shadow” operation revealed a shift toward high‑speed narcolanchas that can exceed 70 km/h, equipped with complex encrypted communication systems to evade law enforcement. The report notes the increasing use of drones and autonomous vessels that require no crew.

Key recommendations include:

• Enhancing maritime surveillance
• Strengthening financial investigations
• Improving forensic expertise to counter the capacity of criminal organizations to introduce large drug quantities into Europe

The largest cocaine bust in Spain prior to these events occurred in October 2024, when over 13 tons hidden among Ecuadorian bananas were seized at the Algeciras port, leading to the arrest of a police commander who concealed more than €20 million in his home.

Operation “White Tide” – Early 2026

In early 2026, “Operation White Tide” became the biggest high‑sea seizure to date: almost 10 tons of cocaine concealed within salt on a vessel intercepted ≈ 500 km from the Canary Islands by the GEO unit of the National Police, with support from the Spanish Navy.
