47 bales of suspected marijuana weighing 2,082 pounds were recovered after the Coast Guard intercepted a suspicious go-fast vessel during a routine patrol, with the haul valued at more than $2.4 million.
Four people were detained after crews from the cutter Escanaba stopped the vessel without incident and then found a "bale field" scattered along its previous route.
JIATF-S did not disclose the exact location, but said Joint Rescue Coordination Center Haiti supported the operation and praised the coordination from detection and pursuit to evidence recovery.
The seizure adds to a broader Trump administration campaign against Western Hemisphere trafficking networks, days after SOUTHCOM said U.S. forces intercepted and sank vessels tied to Los Choneros.
It also follows a larger Coast Guard bust off Puerto Rico last month, when authorities seized more than 7,000 pounds of cocaine worth about $54.5 million and detained five people.
