Indonesian officials intercepted a Mongolian-flagged vessel off Tanjung Balai Asahan containing 1.16 tonnes of ketamine hydrochloride. The massive cache of narcotics was reportedly obtained via a ship-to-ship transfer from a foreign mothership in the Andaman Sea.
Why it matters
The seizure highlights the sophisticated tactics employed by drug traffickers to bypass port security by utilizing high-seas transfers. Authorities are now investigating the Malaysian company that owns the vessel, which had previously disabled its AIS transponder to evade detection.
The seizure totaled 1,160 packages of ketamine divided into 58 individual sacks, with an estimated street value of US$192.64 million. Indonesian police have identified the owning entity in Johor Baru and plan to summon its two directors for questioning.

Timeline
The vessel departed Pasir Gudang, Johor, in early October 2026.
The ship's location was detected off Aceh on October 15, 2026.

Legal Context
The vessel's deliberate deactivation of its AIS transponder marks a direct violation of international maritime safety protocols established under the SOLAS Convention. This tactic highlights the ongoing struggle to monitor shipping activity in complex maritime regions.
This large-scale interdiction may lead to heightened maritime surveillance and more stringent inspection protocols for vessels operating in the Andaman Sea. Residents and maritime logistics firms in the region could face increased security scrutiny following this major discovery.
The takeaway
The successful interception illustrates the critical role of real-time maritime tracking in preventing large-scale transnational drug smuggling. Authorities emphasize that monitoring ship-to-ship transfers remains a primary focus for curbing the influx of illegal substances.
