The chart above is a bit disorienting because South is up.
Dec 20 (Reuters) – The United States is interdicting and seizing a vessel off the coast of Venezuela in international waters, three U.S. officials told Reuters on Saturday, a move that comes just days after U.S. President Donald Trump announced a “blockade” of all sanctioned oil tankers entering and leaving Venezuela.
It also provides an overview of what is happening in regard to the blockade announced by the President.
Apparently the Coast Guard, after seizing the first tanker, is still deeply involved.
“The officials, who were speaking on the condition of anonymity, did not say where the operation was taking place but added the Coast Guard was in the lead.”
The chart at the head of the post was found on Facebook. I can’t vouch for its accuracy, but the list of Navy assets seems to reflect what I have heard from reliable sources so I suspect the Coast Guard assets listed are at least representative, though I question 26135 and 55115 which in silhouette appear to be 87 foot WPBs.
I wish I could give you a more comprehensive overview of what the Coast Guard is doing but I have seen almost nothing official.

From Google AI: Yes, CG26135 is the designation for a specific Search and Rescue (SAR) boat.
But how a TANB got there and what it’s doing are mystifying.
Vessel Details
Role: It is classified as a Search and Rescue vessel.
Dimensions: The boat has an overall length of approximately 8 meters (26 feet) and a width of 4 meters.
Recent Activity: As of mid-2025, it was reported operating near San Juan, Puerto Rico.
Identification: Its Marine Mobile Service Identity (MMSI) number is 338926135.
Context of the Number
The number 26135 fits the USCG’s standard numbering system for its small boat fleet. The first two digits (“26”) typically represent the vessel’s length in feet. In this case, 26135 refers to a 26-foot boat, likely a TanB (Trailerable Assets, Narrow Beam) or a similar response boat model.
I recognized that 26135 should be a 26 foot boat but just seemed terribly out of place.
Might be an over the horizon boat but if so it would be attached to the 210 not counted as a separate asset.
im just gonna say it. I think this graphic is FUBAR – at least for USCG vsls. Maybe I missed it, but did this come from the administration? Looks 3rd party from the imagery/text in the upper right corner.
i do like representing the FRCs as WMSLs tho.
Like I said, I have seen nothing official about Coast Guard units deployed for the blockade. This is definitely third party but since the Navy info is right, I suspect at least the three FRCs and WMEC are correct.
