Launched in August 2025, the U.S. Coast Guard’s Operation Pacific Viper is intercepting large cocaine shipments in the Eastern Pacific to curb maritime trafficking. Operation Pacific Viper uses U.S. Coast Guard cutters, aircraft, and specialized teams to intercept cocaine shipments on the Eastern Pacific route. Crews employ warning shots followed by targeted engine fire to safely stop suspected cartel vessels. Since launch, crews report more than 150,000 pounds seized along a corridor carrying roughly 80% of maritime shipments bound for the U.S., with an estimated $1.1 billion impact. Notable actions include the Cutter Munro’s December 2 stop exceeding 20,000 pounds, plus major hauls by Cutters Stone and James. The campaign has executed 34 stops and 86 arrests with JIATF-South support.
