Canary ports as a new international security vulnerability
The role of the Canary Islands’ ports as key logistics hubs and interconnectors for trade between three continents faces a new international security vulnerability. A report by the International Institute for Strategic Studies (IISS) says Russia uses its so-called ‘shadow fleet’—opaque vessels originally designed to evade trade sanctions—as covert platforms for launching unmanned aerial vehicles (UAVs) into European airspace. The operational pattern, marked by low-cost incursions that are plausibly deniable politically and economically, leaves the archipelago’s maritime facilities in a position of critical exposure to hybrid espionage and unconventional warfare.
The main Canary Island port enclaves, with Las Palmas and Santa Cruz de Tenerife leading, concentrate a massive volume of freight traffic, fuel supply infrastructure (bunkering) and essential subsea telecommunications nodes for connectivity on NATO’s southern flank. The IISS report documents up to 144 suspected drone sightings around European sovereign countries, carried out largely from clandestine boats operating camouflaged within regular commercial shipping traffic. This air-infiltration method bypasses conventional radars thanks to the UAVs’ low altitude and reduced speed, which confuse anti-missile defense systems designed for supersonic projectiles.
North Atlantic precedent and the risk of replication in the island setting
The operational impunity demonstrated by these vessels in waters off Denmark, France or Ireland anticipates the export of similar tactics to the Atlantic frontier of the islands. The analysis details incidents of extreme seriousness, such as the one on January 3, 2025, when the clandestine ship Arctica sailed off the Danish coast as a wave of up to 20 drones flew over the port facilities in Køge before disappearing at sea. Similar actions attributed to the escort vessel Boracay forced the total suspension of civil aviation at Copenhagen Airport in September of the same year.
Community authorities and security analysts warn that the Canary Islands’ ultraperipheral waters provide an ideal environment for concealing these ‘ghost ships’. The very high density of oil tankers and cargo vessels crossing the shipping lanes of the Central Atlantic allows ships such as Fitburg—seized by Finland in early 2026—or Vezhen to effectively blend in with legal crude transport. Gathering information about deployments of the Atlantic Alliance’s military fleet and the visual inspection of critical civilian port infrastructure are described as the priority objectives of a campaign that allied commanders call a ‘strategic failure of continental air defense’.
Radar blind spots and paralysis in the chain of command
The inherent characteristics of the incursions make it harder to coordinate an armed response at Spanish docks. By flying at very low altitudes, unidentified devices are often recorded on port screens as mere birds or small recreational aircraft. In addition, the institutional framework for military response suffers from competence fragmentation that slows agile decision-making on the ground. Port-sector authorities, air navigation and defense bodies operate under separate protocols, which hampers immediate shoot-down orders for well-founded fears of causing civilian casualties or collateral damage in adjacent urban areas.
No Spanish government body has publicly blamed Moscow for these intrusions, mirroring the caution of other European partners, with the only exception of Sweden. This attribution paralysis stems from an institutional tendency to analyze sightings in isolation as individual events, rather than interpreting them as links in a coordinated sabotage strategy. The Kremlin seeks to test the reaction times of state security forces, map vulnerabilities in supply chains, and drive indirect economic costs by disrupting air and port commercial traffic.
Shielding Central Atlantic critical infrastructure
The new logistics normality forces Canary port administrations to rethink investments in peripheral security. Traditional plans focused on physical protection against smuggling, irregular immigration or terrorism prove insufficient against threats that come directly from the airspace. The acquisition of specific anti-drone (C-UAV) systems—made up of high-resolution electronic scanning radars, frequency inhibitors and active interception devices—is beginning to consolidate as a budget priority to prevent cargo terminal paralysis.
The Denmark Defense Command acknowledged serious operational shortcomings after the incidents at its terminals, launching a technological rearmament process that other community partners are now mimicking. The vulnerability of the port front in the Canary archipelago is especially sensitive due to its isolated peripheral status. While commercial operators in Geneva and Rotterdam assess the impact of higher insurance premiums for ships transiting the region, naval bases in the area increase scrutiny of any vessel that turns off its automatic identification systems suspiciously before approaching the island coastline.
