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 East Pac patrol. The 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 413-foot Legend-class 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 a bunch of great images from the narco sub-bust, really 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.
