Maritime Intelligence Key to Counter-Drug Operations
International naval and law enforcement agencies are using shared maritime intelligence to track and intercept drug shipments at sea, as traffickers adapt
Tons of cocaine cross the Atlantic concealed within legitimate cargo every year. To detect these shipments, authorities increasingly rely on maritime intelligence sharing to identify suspicious vessels and track criminal networks.
An analysis by EU Today found that high-risk trade routes and fragmented corporate ownership of ships complicate risk assessments before vessels arrive at port. The separation between vessel owners, operators, and management companies makes ship traceability difficult.
Recent seizures show these practices remain widespread. On July 21, Italy’s Financial Police and customs authorities seized more than 770 kilograms of cocaine hidden among bananas in a refrigerated container at the port of Vado Ligure, according to ANSA news agency. The shipment originated from a major port in Ecuador.
Criminal Networks Shift Offshore
Drug trafficking organizations have modified their methods to reduce detection risk at Europe’s major ports. According to Europol, some networks are moving operations farther offshore, conducting successive transfers at sea across multiple vessels.
One scheme uses mother ships to collect cocaine in Latin America and transport it through international waters. Container ships and bulk carriers then move the drugs to rendezvous points in the Atlantic, where cargo is transferred to high-endurance go-fast boats.
Daniel Pontón, dean of the School of Security and Defense at Ecuador’s IAEN Graduate University, told Diálogo the operational model functions through a system integrating different actors. This flexibility allows networks to constantly innovate.
In the final stage, cocaine is redistributed aboard smaller vessels and landed on isolated beaches, avoiding port inspections. Europol states this model makes reconstructing the logistics chain much harder, allowing networks to continue operating even if one shipment is intercepted.
Contamination of Legitimate Cargo
Cocaine is often inserted into containers carrying legitimate goods at various points in the supply chain. The United Nations Office on Drugs and Crime notes this contamination can occur at farms, packing facilities, distribution centers, during transportation, or inside the port before loading.
A common method is the rip-on/rip-off technique, where criminal organizations place drugs inside containers without the exporter’s knowledge and later remove them at the destination. UNODC says this enables moving large quantities without altering shipment documentation.
Pontón identified ports as a main vulnerability. Differences in port governance models make it difficult for countries to harmonize control strategies.
From Information to Operational Intelligence
Identifying high-risk vessels begins long before they reach port. Naval, customs, and port authorities collect and share information to build maritime domain awareness, transforming scattered data into operational intelligence.
Authorities analyze multiple factors to detect anomalies and develop risk profiles. These include shipping routes, port calls, vessel histories, flag changes, operators, owners, and cargo manifests. This enables prioritized surveillance and focused inspections.
“There is no single model for anticipating this phenomenon because every country faces different realities and institutional capacities,” Pontón said.
Intelligence Sharing for Regional Interdiction
Shared intelligence efforts have evolved into a concrete operational framework in the Western Hemisphere. A principal hub is the Joint Interagency Task Force South, a subordinate organization of U.S. Southern Command that integrates information from U.S. Agencies and partner nations.
For example, between December 2025 and January 2026, Operation Southern Triangle, led by Panama with JIATF-S support, deployed naval and air assets in the Caribbean and eastern Pacific. Operation Pacific Viper, led by the U.S. Coast Guard, seized more than 45 metric tons of cocaine in 2025.
Real-time coordination is the cornerstone. In July 2026, a coordinated operation involving JIATF-S, the Ecuadorian Navy, the Colombian Navy, and the DEA seized nearly 2.7 metric tons of cocaine in the eastern Pacific. A SOUTHCOM maritime patrol aircraft detected and tracked two go-fast boats, relaying their position for interdiction by Ecuadorian naval units.
Operations like this demonstrate how maritime domain awareness translates into action when information flows among surveillance platforms, intelligence fusion centers, and naval units from multiple countries.
Toward a Permanent Security Architecture
Pontón argues international cooperation should focus on strengthening national capabilities through information sharing and technical assistance. These tools are most effective as part of a comprehensive national counterdrug strategy.
As criminal networks fragment operations, the institutional response is integrating sensors, intelligence, and naval capabilities from multiple countries under a coordinated framework. The consolidation of mechanisms like JIATF-S shows the region is moving toward a more permanent maritime security architecture.
