US-Colombia Joint Operation Intercepts Narco-Submarine with 10 Tons of Cocaine in Pacific Waters

PACIFIC OCEAN - Colombian security forces, supported by the United States Department of State Bureau of International Narcotics and Law Enforcement Affairs, executed a joint maritime interdiction on February 9.

The operation targeted a semi-submersible vessel carrying 10 tons of cocaine valued at $441 million. Authorities destroyed the narcotics and arrested four crew members involved in the trafficking attempt.

The interception occurred during routine patrols in international waters off the Colombian coast. This region remains a key transit zone for narcotics from South American production areas to global markets. Bilateral cooperation has led to multiple similar seizures in recent years.

Such operations aim to disrupt supply chains that contribute to regional instability. The destruction of this shipment represents a significant financial loss to trafficking organizations. Continued efforts focus on adapting to evolving tactics employed by these groups.

Operational Details

The narco-submarine was located and boarded without resistance. Colombian naval units, with U.S. advisory support, conducted the search revealing the cocaine cargo. The vessel was scuttled following evidence collection.

These crafts are designed for evasion, operating semi-submerged to avoid detection. Construction often takes place in remote areas. This seizure aligns with patterns of maritime trafficking in the eastern Pacific.
