“Colombian Navy captures unmanned narco submarine in Caribbean Sea” –Naval News

Naval News reports the seizure of an unmanned low profile, semi-submersible that was used to transport illegal drugs.

Not only would semi-autonomous operation eliminate the cost of hiring a crew and the space requirements for accommodations to support the crew, it would also eliminate the possibility of a captured crew becoming a source of intelligence for law enforcement.

It also means that upon boarding there is no one to tell to stop the engines, meaning boardings may be more dangerous than ever.

I would not be surprised to see a remote scuttling option incorporated into future designs.

“Royal Navy makes first ‘narco-sub’ drugs seizure” –BBC

BBC reports,

“HMS Trent has made eight drug seizures since deploying to the Caribbean in December 2023, setting a new record, the Royal Navy added.

“It said the patrol ship had seized more than 9,400kg (20,000lb) of drugs, making it the best hunter of smugglers in the Royal Navy this century.”

Below is the Coast Guard news release regarding the offload.

Coast Guard offloads more than $54 million in illegal narcotics interdicted in Caribbean Sea

Coast Guard Seventh District – (305) 415-6683

MIAMI – The crew of Coast Guard Cutter Diligence offloaded more than 4,125 pounds of cocaine with an assessed street value of approximately $54 million in Port Everglades, Monday.

Coast Guard crews, working alongside interagency and international partners, seized the illegal drugs in the international waters of the Caribbean Sea during three separate interdictions.

The following assets and crews were involved in the interdictions:

  • Royal Navy ship HMS Trent (P 244)
  • U.S. Coast Guard Tactical Law Enforcement Team Pacific (PAC-TACLET)
  • U.S. Coast Guard Cutter Joseph Napier (WPC 1115)
  • U.S. Customs and Border Protection Air and Marine Operations (CBP-AMO)
  • Joint Interagency Task Force South (JIATF-South)

Along with the illicit narcotics, 11 suspected smugglers were apprehended and will face prosecution in federal courts by the U.S. Department of Justice.

“I am extremely proud of our crew’s tenacity and professionalism, coupled with outstanding coordination with Coast Guard aircrews, during this complex counter-drug mission,” said Lt. Matthew Carmine, Coast Guard Cutter Joseph Napier commanding officer. “Their steadfast efforts, along with those of foreign allies and partner agencies, continue to prove vital to countering drug trafficking organizations and safeguarding the people of Puerto Rico and the U.S. Virgin Islands.”

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

These interdictions relate to Organized Crime Drug Enforcement Task Forces’ (OCDETF) 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.

“New Trend: Transatlantic Narco Submarines” –Covert Shores

On June 26, 2024 Spanish police aboard SVA Fulmar interdicted a narco submarine 200 miles from the Canary Islands. The vessel was carrying 900kg of cocaine. The 4 crew scuttled the vessel before being rescued and arrested.–Covert Shores.

Covert Shores reports what appears to be a trend that self-propelled semi-submersibles are being used to transport cocaine directly from Latin America to Europe based on three interceptions beginning, one in March and two in June.

The use of internal diesel engines rather than outboards should not be surprising, considering they are much more fuel efficient that outboards, for the long distances involved.

Footwear Fashion for Boarding Drug Subs

Members of the Coast Guard Cutter Waesche (WMSL-751) law enforcement boarding team inspect a self-propelled semi-submersible (SPSS) in international waters of the Eastern Pacific Ocean, Nov. 20, 2023. The interdiction of the SPSS yielded more than 5,500 pounds of cocaine. In November 2023, Waesche crewmembers seized approximately 18,219 pounds of cocaine, with an estimated street value of over $239 million, during four separate suspected drug smuggling vessel interdictions or events off the coasts of Mexico and Central and South America.

It is a small thing but must be slippery boarding one of these at sea. Took a close look at their footwear. Was a bit surprised, but this would make sense. (Click on the photo to enlarge)

“Navy to establish additional unmanned task forces inspired by Task Force 59” –Defense Scoop

IMX/CE 2022 is the largest multinational training event in the Middle East, involving more than 60 nations and international organizations committed to enhancing partnerships and interoperability to strengthen maritime security and stability.

Defense Scoop reports:

“The Navy plans to stand up additional unmanned task forces around the globe modeled after Task Force 59 in the Middle East, Navy Secretary Carlos Del Toro told reporters Saturday…“We’ve demonstrated with Task Force 59 how much more we can do with these unmanned vehicles — as long as they’re closely integrated together in a [command and control] node that, you know, connects to our manned surface vehicles. And there’s been a lot of experimentation, it’s going to continue aggressively. And we’re going to start translating that to other regions of the world as well,” Del Toro said during a media roundtable at the Reagan National Defense Forum.”

The report goes on to mention 4th Fleet and Oceana specifically, both regions of intense interest to the Coast Guard in regard to drug interdiction and Illegal, Unregulated, Unreported (IUU) fishing respectively.

This could be a big boost to our Maritime Domain Awareness. In the Eastern Pacific Drug Transit Zone we might need uncrewed surface vessels with passive acoustic sensors since the targets of interest are poor targets for radar and optical sensors. That could lead to practical experience that could improve our ASW capability.

Der Spiegel reports that Spanish police have arrested eight and confiscated six underwater drones. The drones were being used to transport drugs from Morocco to Spain across the Straits of Gibraltar.c

Thanks to Sven for bringing this to my attention. 

“Bad Jizz: New Generation Of Narco Submarine Builders Present A Problem” –Covert Shores

Caption from Covert Shores: A new type of ‘narco submarine’ captured by USCG Cutter Active in the Easter Pacific Ocean, May 5, 2021. There is enough that is distinct to give it a fresh family designation, LPV-OM-VSV-10. Although it appears well finished, as far as these things go, many details seem borrowed from other types. The unusual reinforced cockpit leading edge is strongly reminiscent of the LPV-IM-14 and related LPV-IM-VSV-1 types for example. But other features do not match that master boat builder. New narco submarine types are increasingly often copies of various features of established types.

Civilian analysist H. I. Sutton, who has spent a great deal of effort tracking the development of ocean smuggling craft, feels we may be seeing a change in how, and by whom, they are being built.

Narco submarine production may have entered a new phase. After the period of Productionization, we are now seeing greater variance again. This suggests more one-off vessels and, likely, more people designing and building them. It can be characterized as a Commoditization of narco submarine technology.

From the Coast Guard’s perspective, this may not make much difference on the interdiction side, but it may make it more difficult for our partners to attack the problem from shore side.

“Rare Fully-Submersible Narco Submarine Captured In Colombia” –Covert Shores

H. I. Sutton’s “Covert Shores” reports discovery of an apparently fully submersible narco-sub.

 “Early indications are that it is a fully-electric device. It may have been intended to be towed some of the way.”

The Covert Shores post has some original art work that better reveals the configuration along with more photos.
