Below the line is a Coast Guard News release. 

It includes a report of offload of drugs seized by USS Gravely.

Since March the Navy has kept two or three ships deployed to “secure the Southern Border” against illegal immigration and drug smuggling.

Departures of US Navy destroyers were widely reported, frequently with implications that the Coast Guard had not been paying attention to the Southern border or that the Coast Guard was incapable. Center for Strategic and International Studies stated,

First and foremost, the deployments send a powerful signal that the United States is taking border security, and the Western Hemisphere more broadly, seriously. In a statement from U.S. Northern Command (NORTHCOM) upon deployment of the Spruance, the ships will “restore territorial integrity at the U.S. southern border” and will support operations related to “combating maritime related terrorism, weapons proliferation, transnational crime, piracy, environmental destruction, and illegal seaborne immigration.” The tasking of some of the United States’ most exquisite naval capabilities to support Southwest border operations accordingly provides yet another indicator that a strategic pivot to the Western Hemisphere in general, and the U.S.-Mexico border in particular, is well underway.

The DDGs are marvelous ships as demonstrated by their performance against the Houthis in the Red Sea. Their more sophisticated sensors were also touted, but the results have been underwhelming.

Results:

So what happened? Let’s give credit where credit is due.

Guided missile destroyers involved, as far as I can determine, have been USS Gravely, USS Spruance, USS Stockdale which replaced Spruance in mid April, USS Cole which very recently replace Gravely, and Sampson which just replaced Stockdale.

As far as I can tell, the interdiction of 840 pounds of cocaine valued $13.7M by USS Gravely, which deployed March 15, reported below, is the only interception of drugs reported by a destroyer in the almost three months since their intervention began.

By comparison:

USS Minneapolis-Saint Paul (LCS-21) which deployed March 25 has made three interdictions. USS Charleston Deployed May 21. I presume she is replacing Minneapolis-Saint Paul. The first two resulted in seizure of 580 kilograms (1,279 pounds) of cocaine valued at $9,463,860 and 1,125 kilograms (2,480 pounds) of marijuana valued at $2,807,360. I was not able to find similar figures for the third.

In an earlier post I posted the results of drugs landed on thirteen different occasions from February 13 to May 2, 2025 comparing interdictions in the Eastern Pacific with those made in the Atlantic, Gulf, and Caribbean. In total 168,574 pounds or more than 84 tons, valued at $1,702.9 million. There have been additional offloads since then including the one below.

That is 196 times as much as was seized by Navy Destroyers. Only a very small part of which was marijuana rather than cocaine, none of which was seized in the Eastern Pacific. Notably no Fentanyl was included.

Our Canadian and Netherlands Navy partners each seized more contraband than the US Navy this period.

Why the poor showing?:

Functionally the DDGs should have been at least as effective as other units doing this mission, so why weren’t they more effective?

I think because they were looking in the wrong place.

Early announcements seem to indicate they primarily being deployed primarily to interdict immigrants with drug interdiction a secondary mission, but as I noted in the earlier post,

Perhaps surprisingly, cutters in the Western Atlantic areas looking for drugs don’t intercept many migrants and cutters looking for migrants don’t find much in the way of drugs or even migrants. There were four WMEC patrols identified as looking for migrants. None of the four found any drugs. One intercepted no migrants. The three remaining patrols intercepted a total of 184.

The West coast deployment seems to have been in vicinity of San Diego. Most drug interdictions in the Pacific happen off the Central and South American coast.

There has been something of a surge in maritime illegal migrant interdictions on the West Coast but they have been concentrated close to shore near San Diego and the Mexican border, using recreational style small craft, but the totals are still relatively small.

As far as I have heard (and I think I would have) none of the US Navy ships have intercepted any immigrants.

Other thoughts:

Any assistance the Navy might provide is always welcome, but any implication that the Coast Guard has not been working the problem with considerable success, limited only by resources available, is unfair. There simply is no such thing as 100% secure.

The Navy has also provided additional ISR resources. Both the Navy and Coast Guard can only benefit from better Maritime Domain Awareness even if the information is used for different purposes.

Having an alert, active DDG positioned off US naval bases (like San Diego) might be a good idea since, as yet, we really have no land based missile defenses capable of countering cruise missiles that might be launched from container ships in an initial surprise attack.

Coast Guard offloads more than $138 million in illicit drug interdictions in Caribbean Sea

Coast Guard Seventh District – 786-367-7649

MIAMI –U.S. Coast Guard Cutter Valiant’s crew offloaded 17,450 pounds of cocaine and 2,585 pounds of marijuana worth $132 million, Friday, at Port Everglades.

U.S. Coast Guard Cutter Vigorous crew offloaded approximately 840 pounds of cocaine worth an estimated $6.2 million, Thursday, at Coast Guard Base Miami Beach.

The seized contraband was the result of six interdictions in the Caribbean Sea by Coast Guard and interagency partners.

“I am incredibly proud of our Valiant team and how they exemplify American values. They sacrifice time away from their families and when necessary, put themselves in harm’s way to secure our borders and protect the American people,” said Cmdr. Matthew Press, commanding officer of Valiant. “Collaborating with the United States Navy, Royal Canadian, and Royal Netherlands Navies, our multinational team disrupted transnational criminal organizations making the world a safer place.”

On May 19, a maritime patrol aircraft located a suspicious vessel approximately 85 miles north of Aruba. Valiant’s crew interdicted the vessel and seized approximately 2,645 pounds of cocaine.

On May 22, a maritime patrol aircraft located a suspicious vessel approximately 170 miles north of Aruba. Valiant’s crew interdicted the vessel and seized approximately 7,750 pounds of cocaine.

On May 25, a maritime patrol aircraft located a suspicious vessel approximately 290 miles south of the Dominican Republic. USS Gravely’s crew and embarked U.S. Coast Guard Law Enforcement Detachment 401 interdicted the vessel and seized approximately 840 pounds of cocaine. The narcotics were transferred to the Vigorous.

On May 29, a maritime patrol aircraft located a suspicious vessel approximately 140 miles south of the Dominican Republic. His Majesty’s Canadian Ship William Hall’s crew and embarked Coast Guard LEDET 103 interdicted the vessel and seized approximately 750 pounds of cocaine. The narcotics were transferred to the Valiant.

On May 29, a maritime patrol aircraft located a suspicious vessel approximately 15 miles north of Venezuela. The Royal Netherlands Navy ship HNLMS Friesland crew and embarked Coast Guard LEDET 404 interdicted the vessel and seized approximately 4,050 pounds of cocaine and 2,585 pounds of marijuana. The narcotics were transferred to the Valiant.

On May 31, a maritime patrol aircraft located a suspicious vessel approximately 185 miles north of Colombia. HMCS William Hall’s crew and embarked Coast Guard LEDET 103 interdicted the vessel and seized approximately 2,250 pounds of cocaine. The narcotics were transferred to the Valiant.

The following crews assisted with interdiction operations:

Detecting and interdicting illicit drug traffickers on the high seas involves significant interagency and international coordination. Joint Interagency Task Force-South, in Key West, conducts the detection and monitoring of aerial and maritime transit of illegal drugs. Once an interdiction becomes imminent, the law enforcement phase of the operation begins, and control of the operation shifts to the U.S. Coast Guard for the interdiction and apprehension phases. Interdictions in the Caribbean Sea are performed by members of the U.S. Coast Guard under the authority and control of the Seventh Coast Guard District, headquartered in Miami.

These interdictions relate to Organized Crime Drug Enforcement Task Forces’ Strike Force initiatives and designated investigations. OCDETF identifies, disrupts, and dismantles the highest-level criminal organizations that threaten the United States using a prosecutor-led, intelligence-driven, multi-agency approach.

Coast Guard interdicts 16 aliens near Mission Bay

SAN DIEGO — Coast Guard interdicted a vessel with 16 aliens aboard approximately 15 miles off the coast of Mission Bay, Sunday morning.

At approximately 12 a.m., U.S. Coast Guard Cutter Active notified Joint Harbor Operations Center of a 25-foot panga-style with around 15-20 people aboard approximately 1 mile south of their position.

The cutter Active and a U.S. Customs and Border Protection Air and Marine Operations boatcrew then launched boarding teams to assess.

The Coast Guard boarding team discovered 16 aliens aboard the panga. Initial interviews revealed that all the aliens claimed Mexican nationality.

The aliens were safely transferred to U.S. Border Patrol custody.

The Coast Guard remains committed to protecting lives at sea while working alongside our federal partners to combat illicit maritime activities. These operations highlight the coordinated efforts between agencies to secure our maritime borders.

SAN DIEGO — Coast Guard interdicted a panga with 14 aliens aboard approximately 20 miles off the coast of Point Loma, Tuesday night.

At approximately 4:45 p.m., U.S. Customs and Border Protection notified Coast Guard personnel at the Joint Harbor Operations Center of a panga-style vessel traveling north toward the maritime boundary line.

The Coast Guard Cutter Terrell Horne was diverted to the scene. The cutter launched a boarding team, and with CBP’s assistance, successfully interdicted the vessel.

The boarding teams discovered 14 individuals aboard the panga. Initial interviews revealed that all individuals claimed Mexican nationality.

The aliens were safely transferred to U.S. Border Patrol custody.

The Alien Migrant Interdiction Operations (AMIO) mission provides effective law enforcement presence at-sea and achieves three main objectives: deter undocumented migrants and transnational smugglers from using maritime routes to enter the U.S.; detect and interdict undocumented migrants and smugglers far from the U.S. border; and expand Coast Guard participation in multi-agency and bi-national border security initiatives. Strong partnerships and information sharing with other agencies, such as Customs and Border Protection (CBP), are critical to mission success. While the Coast Guard leads the interdiction mission on the high seas, partnerships with CBP and Immigration and Customs Enforcement are critical for successful shore-side interdiction operations.

U.S. Coast Guard District Eleven

OCEANSIDE, Calif. — Coast Guard crews interdicted a panga-style vessel carrying 26 individuals approximately one mile offshore from Oceanside Harbor, Monday morning.

At around 10:30 a.m., Oceanside lifeguards reported a disabled vessel with multiple people aboard that had run out of fuel. Assessing no immediate safety concerns, lifeguards notified Coast Guard personnel at the Joint Harbor Operations Center and remained on scene.

The Coast Guard Cutter Terrell Horne was diverted to assist. Terrell Horne’s crew deployed a boarding team and safely embarked the 26 individuals, who represented multiple nationalities, including those from Mexico, China, and Vietnam. The individuals were later transferred to U.S. Border Patrol custody.

The Coast Guard works closely with partner agencies to deter and respond to dangerous smuggling operations that endanger lives.

Jan. 17, 2025

The U.S. Coast Guard and partnership agencies interdicted a 25-foot panga-style vessel carrying 15 individuals approximately 25 miles off Point Loma, Thursday.

The boat crew arrived on scene and issued commands for the vessel to stop. The operator abandoned the steering console, which caused the vessel to drift erratically. Coast Guard gained control of the vessel and turned off the engine. During this process, the panga collided with the Coast Guard small boat, resulting in minor damage to the starboard railing.

The 15 individuals aboard the vessel were determined to represent multiple nationalities, including China, Uzbekistan, Mexico, Ecuador, Vietnam, and El Salvador.

One individual was observed experiencing hypothermia-like symptoms and was transported by emergency medical services to UCSD Hillcrest for medical evaluation, accompanied by Border Patrol agents.

All 15 individuals were safely transferred to U.S. Border Patrol custody.

The Coast Guard continues to work closely with partner agencies to deter and respond to dangerous smuggling operations that put lives at risk.

 

“US Coast Guard Cutter Seneca returns home after a two-month patrol in the Windward Passage and Florida Straits” –News Release

U.S. Coast Guard Cutter Seneca (WMEC 906) patrols off the coast of Haiti, April 13, 2024, during a deployment to the Windward Passage. The crew of Seneca completed a 58-day patrol in the Windward Passage and Florida Straits to deter illegal migration while supporting Homeland Security Task Force – Southeast (HSTF-SE) and Operation Vigilant Sentry (OVS). (U.S. Coast Guard photo)

Below is a District 7 news release. The unstated news here is that in spite of being almost two months in the area where migrants are expected to attempt to sail to the US, Seneca apparently made no intercepts. That is good news. The patrols, along with changes in immigration policy, are in fact discouraging attempts to migrate illegally by sea, at least in this area.

The ship also got to participate in Miami’s Fleet Week and was visited by the Secretary of the Navy. All good.

US Coast Guard Cutter Seneca returns home after a two-month patrol in the Windward Passage and Florida Straits

PORTSMOUTH, Va. — The crew of U.S. Coast Guard Cutter Seneca (WMEC 906) returned to their home port in Portsmouth, May 21, 2024, following a 58-day migrant interdiction patrol in the Windward Passage and Florida Straits.

Seneca’s crew deployed in support of Homeland Security Task Force – Southeast (HSTF-SE) and Operation Vigilant Sentry (OVS) while at sea in the Coast Guard Seventh District’s area of operations.

Patrolling off the coast of Haiti and southern Florida Straits, Seneca’s presence helped deter migrants from taking to the sea in unsafe vessels to ensure the safety of life at sea and protect the maritime borders of the United States.

While at sea, Seneca worked with a Coast Guard Air Station Miami HC-144 Ocean Sentry airplane crew and responded to an international search and rescue case involving an overboard passenger who fell from a cruise ship.

During the deployment, Seneca’s crew had the opportunity to attend the inaugural Fleet Week 2024 in Miami, Florida in early May. Crew members conducted nearly 1,000 public tours over a six-day period, showcasing the U.S. Coast Guard, cutter Seneca, and the service’s missions. Seneca hosted numerous VIPs aboard to include Secretary of the Navy Carlos Del Toro, local and state politicians.

“It’s been an honor leading Seneca and her crew, serving alongside the best and brightest women and men in the service,” said Capt. James F. McCormack, commanding officer of Seneca. “Seneca and her crew provided stability in the maritime environment of the South Florida Straits and represented the Coast Guard with distinction amongst the other U.S. maritime services at Fleet Week Miami. Seneca lived up to our motto, “Tradition of Honor, A Legacy of Action.””

While deployed, Seneca’s crew transited over 9,000 nautical miles.

Established in 2003, HSTF-SE is the Department of Homeland Security-led interagency task force charged with directing operational and tactical planning, command and control, and functions as a standing organization to deter, mitigate, and respond to maritime mass migration in the Caribbean Sea and Florida Straits.

OVS is the 2004 DHS plan that provides the structure for deploying joint air and surface assets and personnel to respond to irregular maritime migration in the Caribbean corridor of the United States. Its primary objectives are to protect life at sea while deterring and dissuading mass maritime migration alongside our federal, state, and local partners.

Seneca is a 270-foot, Famous-class medium endurance cutter. The cutter’s primary missions are counter drug operations, migrant interdiction, enforcement of laws and treaties, and search and rescue in support of U.S. Coast Guard operations throughout the Western Hemisphere.
