Back to Alto su barco!

The crew of the Coast Guard Cutter Waesche (WMSL 751) offloaded a little over 9 tons of Colombia’s finest, worth something like $239 million, on Wednesday in San Diego after the conclusion of her latest 89-day East Pac patrol.

The 418-foot cutter– with a Helicopter Interdiction Tactical Squadron (HITRON) MH-65 Dolphin helicopter and aircrew, members from Law Enforcement Detachment (LEDET) 101 and 102, and contractors who flew a Scan Eagle UAV embarked– patrolled more than 19,750 nautical miles conducting law enforcement and search and rescue operations in international waters off Central and South America.

The 9-ton dope haul came from six interdictions at sea– four by Waesche and two by the smaller 210-foot USCGC Active who transferred her impounds to the larger national security cutter to bring in.

The biggest of the interdictions, on 20 November, was from a narco sub, officially a “self-propelled semi-submersible” (SPSS) that was shipping more than 5,500 pounds of blow. Of note, the interdiction of the SPSS was the first (caught) in the Eastern Pacific since 2020.

11th District released many great images from the narco sub-bust, showing just how big it is with the cutter’s 26-foot RHIB as a size reference.

If you ask me, those brainstorming about using more advanced (unmanned) narco subs to supply Marines on remote West Pac islands in the event of a China dustup make some sense.

Of note when it comes to the WMSL program, the 10th member of the class, the brand new USCGC Calhoun (WMSL 759), departed Pascagoula on 19 November for her homeport in Charleston.

Inside the sneaky dope sub

The Coast Guard Cutter Stratton crew seizes cocaine bales from a self-propelled semi-submersible (SPSS, a/k/a/ sneaky dope sub, a/k/a narco nautilus) interdicted in international waters off the coast of Central America, July 19, 2015. The Coast Guard recovered more than 6 tons of cocaine from the 40-foot vessel.

Interesting footage of the Stratton‘s 35 foot LRI-II notching in the rear ramp of the big 418-foot National Security Cutter. I’ve done it on a 17 footer in the back of a WPB and it was a blast so I can only imagine the scale involved here.
