Clarence Sutphin Jr. was operating under Combined Task Force 150, one of five task forces under Combined Maritime Forces, the largest multinational naval partnership in the world. CTF 150 focuses on maritime security operations outside the Arabian Gulf. Crimson Barracuda counters terrorist and criminal organizations’ use of the high seas to smuggle narcotics, weapons, and other illicit substances in the Indian Ocean, Arabian Sea and Gulf of Oman.

I would note two things about this particular incident. The use of “Canadian space-based intelligence” to cue the cutter’s interdiction, and second, that you can see Long Range Acoustic Devices mounted on the cutter in the photo above. Below is a close-up.

MANAMA, Bahrain —The Canadian-led Combined Task Force (CTF) 150 carried out two drug interdictions at sea in a single day as part of Focused Operation Crimson Barracuda in the Arabian Sea, April 10. The two interdictions resulted in the seizure of a combined total of nearly 2,000 kg of drugs.

The Royal Navy’s HMS Lancaster, a Duke-class Type 23 frigate, seized over 800 kg of hashish, 390 kg of methamphetamines and 110 kg of heroine from a stateless dhow in the Arabian Sea. This was the crew’s first day of deployment after completing a crew swap a few weeks before.

“I am exceptionally proud of the entire team in Lancaster executing this interdiction on the first day of our deployment,” said Royal Navy Cmdr. Chris Sharp, HMS Lancaster’s commanding officer. “Complex interdictions in such a challenging environment require true teamwork across the entire ship’s company. This success is shared with our partners in CTF 150 who provided essential support to the operation.”

Then, using Canadian space-based intelligence, the Sentinel-class fast-response cutter USCGC Clarence Sutphin Jr. (WPC 1147) seized 257 kg of methamphetamines, 92 kg of heroine, 17 kg of amphetamines, 296 kg of hashish, and 15 kg of marijuana from another dhow in the Arabian Sea. After weighing and documenting the hauls, the crew disposed of the narcotics.

Clarence Sutphin Jr is forward deployed to Bahrain as part of a contingent of U.S. Coast Guard ships under Patrol Forces Southwest Asia (PATFORSWA). PATFORSWA deploys Coast Guard personnel and ships alongside U.S. and regional naval forces throughout the Middle East.

“These two interdictions have made a significant dent in criminal and terrorist organizations’ ability to use drugs to fund their activities,” said Royal Canadian Navy Capt. Colin Matthews, Commander Combined Task Force 150. “The collaboration of our assets and personnel allowed us to become a precise and highly effective team that not only undermined the efforts of these organizations, but also nearly 2,000 kg of drugs from hitting the streets.”

MANAMA, Bahrain —April 08, 2024

A U.S. Coast Guard cutter, working in direct support of Combined Task Force (CTF) 150, of Combined Maritime Forces, seized nearly 400 kilograms of illegal drugs from a dhow in the Arabian Sea, April 4.

Crewmembers from the Sentinel-class fast response cutter USCGC Glen Harris (WPC 1144) discovered and seized 15 kilograms of heroin and 375 kilograms of methamphetamine aboard the dhow. After weighing and documenting the haul, the crew properly disposed of the narcotics.

“This is the second major interdiction of the USCGC Glen Harris and the CTF-150 team with a combined total of 1,160 kg of drugs seized to date, denying income to criminal and terrorist organizations from the profits of illicit narcotics,” said Capt. (N) Colin Matthews, commander of CTF-150. “This exceptional multinational cooperation between our two teams is an example of the impacts we can make when we work together.”

On March 5, Glen Harris, working in support of CTF 150, seized 770 kilograms of methamphetamines from a dhow in the Arabian Sea.

Glen Harris is forward deployed to Bahrain. The fast response cutter is part of a contingent of U.S. Coast Guard ships forward-deployed to the region under Patrol Forces Southwest Asia (PATFORSWA).

“U.S. attempts to stop arms smuggling to Yemen with limited resources” –Is the Coast Guard the Answer?

US Coast Guard / CENTCOM released photo of weapons seized aboard an Iranian dhow on February 15 2024. The seizure included UUV and USV components. The annotations, highlighting possible UUV parts, have been added.

The Washington Post reports,

“The Biden administration is expanding efforts to surveil and intercept Iranian weapons being smuggled to Yemen, where Houthi militants have staged a deadly campaign of violence against commercial shipping that has proved resilient to six weeks of military strikes, said U.S. officials familiar with the matter.

The initiative seeks to map seafaring routes used by Tehran and stop the arms shipments while in transit, an acknowledgment that the Houthis are likely to pose a significant security challenge for the foreseeable future. It is part of a broader strategy that also includes sanctions and diplomatic pressure but faces constraint as essential military resources are in short supply.

This sound, to an old Coastie, a lot like what lead to the creation of Coast Guard Squadron One (ultimately 26 Point class 82-foot patrol boats) and Squadron Three (five to seven High Endurance cutters) during the Vietnam War.

At the very least expect more Coast Guard boarding teams to be operating with the Navy.

The Webber class Fast Response Cutters (FRC) are the weapon of choice here. The Navy never bothers to produce small ships suitable for the interdiction of clandestine coastal shipping, while this has always been a type common in the Coast Guard fleet. Six FRCs are already operating with the 5th Fleet out of Bahrain. They are already intercepting arms smugglers, as well as drug smugglers that finance Iranian proxy movements. The Coast Guard already has 55 FRCs and is procuring at least ten more.

Will we see more cutters assigned to 5th Fleet? They are also short of air assets. Will we see Coast Guard fixed wing aircraft searching the Arabian Sea?

Canadian-led Combined Task Force 150 seizes 770 kg of methamphetamine in the Arabian Sea

MANAMA, Bahrain —

A U.S. Coast Guard cutter operating under the Canadian-led Combined Task Force(CTF) 150 of Combined Maritime Forces seized 770 kg of methamphetamine from a dhow in the Arabian Sea, March 5.

Based on intelligence provided by CTF 150, the Sentinel-class fast response cutter USCGC Glen Harris (WPC 1144) seized the methamphetamines and, after documenting and weighing the illicit haul, properly disposed of it.

“I am extremely proud of the work of the Combined Task Force 150 team and USCGC Glen Harris in preventing these drugs from reaching their final destination. This interdiction demonstrates the value of multinational efforts within the Combined Maritime Forces to prevent and disrupt criminal and terrorist organizations at sea,” said Canadian Navy Capt. Colin Matthews, Commander CTF 150.

Glen Harris is forward deployed to Bahrain. The fast response cutter is part of a contingent of U.S. Coast Guard ships operating in the region under Patrol Forces Southwest Asia (PATFORSWA). PATFORSWA deploys Coast Guard personnel and ships alongside U.S. and regional naval forces throughout the Middle East.

“CENTCOM (USCGC Clarence Sutphin Jr.) Intercepts Iranian Weapons Shipment Intended for Houthis” –U.S. Central Command Public Affairs –U.S. Central Command Public Affairs

Feb 15, 2024 ,U.S. 5TH FLEET – The U.S. Coast Guard Sentinel-class fast-response cutter USCGC Clarence Sutphin Jr. (WPC 1147) seizes a vessel carrying military-grade weapons and other lethal supplies in the Arabian Sea, Jan. 28. Clarence Sutphin Jr. operates in the U.S. 5th Fleet area of operations to help ensure maritime security and stability in the Middle East region.

Below is a US Central Command news release

Feb 15, 2024, U.S. 5TH FLEET – Military-grade weapons and other lethal supplies are stacked on the deck of a vessel seized by the U.S. Coast Guard Sentinel-class fast-response cutter USCGC Clarence Sutphin Jr. (WPC 1147) in the Arabian Sea, Jan. 28. Clarence Sutphin Jr. operates in the U.S. 5th Fleet area of operations to help ensure maritime security and stability in the Middle East region.

A U.S. Coast Guard cutter, forward deployed to the U.S. Central Command (CENTCOM) area of responsibility, seized advanced conventional weapons and other lethal aid originating in Iran and bound to Houthi-controlled areas of Yemen from a vessel in the Arabian Sea on Jan. 28.

The U.S. Coast Guard Sentinel-class fast-response cutter USCGC Clarence Sutphin Jr. (WPC 1147), assigned to U.S. Naval Forces Central Command, located the vessel and boarded it in the Arabian Sea. The boarding team discovered over 200 packages that contained medium-range ballistic missile components, explosives, unmanned underwater/surface vehicle (UUV/USV) components, military-grade communication and network equipment, anti-tank guided missile launcher assemblies, and other military components.

The direct or indirect supply, sale or transfer of such aid violates U.N. Security Council Resolution 2216 (as extended and renewed by resolutions 2675 and 2707).

“This is yet another example of Iran’s malign activity in the region,” said Gen. Michael Erik Kurilla, CENTCOM commander. “Their continued supply of advanced conventional weapons to the Houthis is in direct violation of international law and continues to undermine the safety of international shipping and the free flow of commerce.”

CENTCOM is committed to working with our allies and partners to counter the flow of Iranian lethal aid in the region by all lawful means including U.S. and U.N. sanctions and through interdictions.

Illegal Drugs Seized by CMF French-led Combined Task Force 150 in Arabian Sea

MANAMA, Bahrain —

A U.S. Coast Guard cutter operating under the French-led Combined Task Force 150 of the Combined Maritime Forces seized about $8.1 million worth of illegal drugs from a vessel in the Arabian Sea, Jan. 16.

The Sentinel-class fast response cutter USCGC Emlen Tunnell (WPC 1145) seized 173 kilograms of methamphetamines following a search. The Coast Guardsmen properly disposed of the drugs and released the vessel.

This is the second interdiction by CTF 150 of the year and marks the 14th time they have seized illegal narcotics at sea since France took command in July 2023. During their tenure, more than 16 tons of illegal narcotics with a street value of over $600 million were seized and disposed of, preventing criminal and terrorist organizations generating income from drug smuggling. The seizure came one day before France turned over command of the task force to the Royal Canadian Navy.

The mission of Combined Task Force 150 is to disrupt the ability of non-state actors to move weapons or drugs, or engage in other illicit activities, in the Gulf of Oman, Arabian Sea and Indian Ocean.

CTF 150 is one of five task forces under Combined Maritime Forces, the world’s largest multinational naval partnership, and focuses on maritime security operations in the Gulf of Oman, Arabian Sea and Indian Ocean.

Canada Assumes Command of Combined Maritime Forces’ Combined Task Force 150

MANAMA, Bahrain —

The Royal Canadian Navy assumed command of a multinational maritime task force during a change-of-command ceremony Jan. 17.

French Navy Capt. Yannick Bossu turned over command of Combined Task Force 150 to Royal Canadian Navy Capt. Colin Matthews. CTF 150 was established in February 2002, and is one of five operational task forces under Combined Maritime Forces. CTF 150 conducts maritime security operations outside the Arabian Gulf against threats from non-state actors. The core staff of CTF 150 consisted of French, British, New Zealanders, Australians, and Bahrainis.

Since France took command of CTF 150 in July 2023, ships working in support of the task force carried out 14 successful boardings, in which more than 16 tons of illegal narcotics with a street value of over $600 million were seized. These seizures prevent criminal and terrorist organizations generating income from drug-smuggling.

While Commander of CTF 150, Bossu also spread CMF’s message through key partner engagements with countries including Seychelles, Mozambique and India. These engagements help strengthen ties between CMF nations and provides an opportunity to discuss the work of CMF with countries not yet members.

“Today marks the end of the French Navy’s successful 12th command of CTF 150. I would like to express my thanks to all those who have continually supported us during our tenure, including Vice Admiral Cooper, Commodore Anderson, Commodore Dennis and Rear Admiral Al bin Ali,” Bossu said. “Integral to CTF 150’s achievements over the past six months are, of course, the French, British, American, Indian, and Pakistani ships that have been working in support and my team made up of staff from a range of nations. We are pleased to welcome the Royal Canadian Navy to Combined Task Force 150; it has been a pleasure to meet your team. To everyone, keep on enjoying and serving in Combined Maritime Forces.”

Matthews joins CTF 150 following a tour as Director of Naval Information Warfare. Over the years, he has participated in numerous overseas deployments to the Arabian Gulf and Arabian Sea regions in support of counterterrorism operations.

“It is an honor to take command of Combined Task Force 150 and a privilege to lead this team of dedicated personnel from Canada, Bahrain, Australia, and New Zealand for the next six months,” Matthews said. “We are eager to build on the achievements of Capt. Bossu and his team. The success of this operation lies with our ability to work with like-minded nations toward the same goals, ensuring that legitimate commercial shipping can transit the region free from non-state threats and we are ready to face this task.”

Combined Maritime Forces, headquartered in Bahrain with U.S. Naval Forces Central Command and U.S. 5th Fleet, is the largest multinational naval partnership in the world, with 39 nations committed to upholding the international rules-based order at sea. It promotes security, stability and prosperity across approximately 3.2 million square miles of international waters, encompassing some of the world’s most important shipping lanes.

CMF’s other task forces include CTF 151, which leads regional counter-piracy efforts; CTF 152, dedicated to maritime security in the Arabian Gulf; CTF 153, providing maritime security in the Red Sea; and CTF 154, which delivers maritime training.

K-LOGIR, Korean Low cOst Guided Imaging Rocket and Launcher

K-LOGIR launcher fitted on a Textron CUSV USV at Sea Air Space 2021. The system was showcased by Raytheon and LIG Nex1.

Naval News recently did a post highlighting a 4th Fleet live fire test combining a Korean developed fire and forget guided rocket system with the Common Uncrewed Surface Vessel (CUSV) cued to a target by a Radiosonde UAS for a fully uncrewed kill chain.

The “Poniard” Korean-Low cOst Guided Imaging Rocket (K-LOGIR) is closely related to the APKWS, both being based on the 70mm Hydra unguided rocket. Unlike the semi-active laser homing APKWS, the K-LOGIR is a fire-and-forget system allowing multiple simultaneous engagements.

Most of the reports I have read on this exercise are unclear if six missiles hit a single target or if six missiles hit six different targets, but this Defense Mirror report, “Textron’s Unmanned Boat Uses South Korean Weapon to Engage Multiple Targets.” makes it clear that multiple targets were engaged in a single salvo.

I don’t fully understand how they designate different targets for the missiles in the salvo, but it may be that they are sending them to different waypoints before they initiate their search.

The ability to engage several targets simultaneously makes this system attractive for countering surface swarm tactics like those that might be encountered by PATFORSWA, but for the Ports, Waterways, and Coastal Security mission, the APKWS’ semi-active laser homing might be a better solution, in that we are unlikely to have to engage numerous targets in a single salvo and we may want to target particular parts of an adversary’s vessel or perhaps engage low-level air targets such as UAS, helicopters, or general aviation aircraft. Presumably, APKS could be fired from the same launcher.

Take a look at the launcher above and below. Here it is mounted on an unmanned 39-foot boat. In the photo above you can see that it traverses and elevates. It appears to hold up to six rockets. It might be an appropriate way to arm Coast Guard patrol boats and larger cutters with APKWS, but “Vampire” might be even simpler.

I would really like to see 4th Fleet make more effort to publicize their experimentation efforts. I’m surprised I was not able to find a YouTube video that documented this test and I have seen no mention of it on the 4th Fleet website.

I am also curious to know if the Navy’s 39′ CUSV could be operated from the stern ramp of a National Security Cutter. Interoperability?

CMF-assigned Cutter Seizes Hashish and Methamphetamines in North Arabian Sea | January 02, 2024, MANAMA, Bahrain

A U.S. Coast Guard cutter patrolling under the command of Combined Task Force 150 of the Combined Maritime Forces seized hashish and methamphetamines with a total estimated street value of $24.3 million Dec. 28 in the North Arabian Sea.

It was the third seizure by a CMF-assigned cutter in four days, following seizures by USCGC Clarence Sutphin Jr. (WPC 1147) and USCGC John Scheuerman (WPC 1146) of hashish, heroin, methamphetamines and pills with a total estimated street value of $24.5 million Dec. 24 and Dec. 26 in the Gulf of Oman.

A team from USCGC Robert Goldman (WPC 1142), a Sentinel-class cutter, boarded a dhow at approximately 6:30 a.m. local time Dec. 28 after it displayed indicators consistent with illicit drug trafficking.

Aboard, the team discovered over 300 bags of drugs containing 3,514 kilograms of hashish and 417 kilograms of methamphetamines.

The Robert Goldman team released the dhow and disposed of the illicit drugs.

The mission of Combined Task Force 150 is to disrupt the ability of non-state actors to move weapons or drugs, or engage in other illicit activities, in the Gulf of Oman, Arabian Sea and Indian Ocean.

This interdiction marked the twelfth time Combined Task Force 150 assets have seized illegal narcotics at sea since France took command in July 2023.

Combined Maritime Forces is a multinational maritime partnership committed to disrupting criminal and terrorist activities by restricting their freedom of maneuver across approximately 3.2 million square miles of international waters encompassing some of the world’s most important shipping lanes.

Since 2021, units assigned to the Combined Maritime Forces have seized more than $1 billion in illegal drugs while patrolling waters across the Middle East.

An unusual photo from the December 28 edition of the US Naval Institute News Service’s Fleet and Marine Tracker. The Avenger class, like the cutters, are based in Bahrain.

Why this get together? I presume this is an exercise in which the FRCs protect the MCM ships from Iranian drones or small craft swarm tactics. Alternately the exercise may have been for the cutters to protect high value units, with the MCM ships simulating larger ships, but FRCs already routinely escort high value units, though I don’t think I have seen this many involved in a single operation.

Below is a news release from U.S. Naval Forces Central Command Public Affairs. While apparently drugs were seized, there is no indication they seized the smuggling vessel nor arrested its crew. That seems surprising.


MANAMA, Bahrain —A U.S. Coast Guard ship seized illegal drugs worth over $6 million from a fishing vessel in the Gulf of Oman, Dec. 12.

Crewmembers from the Sentinel-class fast response cutter USCGC Glen Harris (WPC 1144) observed individuals on a fishing vessel throw seven bales of material over the side. The material was discovered to be 174 kilograms of heroin.

Glen Harris arrived in the Middle East region last year and operates from Naval Support Activity Bahrain.

The fast response cutter is part of a contingent of U.S. Coast Guard ships forward-deployed to the region under Patrol Forces Southwest Asia (PATFORSWA). PATFORSWA deploys Coast Guard personnel and ships alongside U.S. and regional naval forces throughout the Middle East.
