“We have done a lot of work with AI previously, and we’ve done computer vision, we’ve done anomalous behavior detection, we’ve done AI-enabled [command and control], but we’ve done all of those separately,” the commodore explained. “At Digital Horizon, for the first time ever, we did that together on a single stack, and that’s all integrated on a single pane of glass.”
There is also confirmation here that a similar effort will be going into 4th Fleet (Latin American/Caribbean Waters); that it will involve partner nations; and that it will look at IUU fishing as well as drug interdiction.
Fortunately, it looks like Coast Guard personnel and assets have been intimately involved in this effort and it looks like it will benefit our Maritime Domain Awareness (MDA) efforts.
(Will the Coast Guard’s next class of ships be USV tenders?)

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.

U.S. Naval Forces Intercept Explosive Material Bound for Yemen
By U.S. Naval Forces Central Command Public Affairs | November 15, 2022
MANAMA, Bahrain —
On Nov. 8, U.S. 5th Fleet intercepted a fishing vessel in the Gulf of Oman smuggling lethal aid, including a large quantity of explosive material, from Iran to Yemen.
U.S. Coast Guard ship USCGC John Scheuerman (WPC 1146) (emphasis applied–Chuck) and guided-missile destroyer USS The Sullivans (DDG 68) interdicted the vessel as it transited international waters. Patrol coastal ship USS Hurricane (PC 3) and Navy explosive ordnance disposal technicians from U.S. 5th Fleet’s Task Force 56 also assisted during a weeklong effort to fully search the vessel and verify the type of material found.
U.S. forces discovered more than 70 tons of ammonium perchlorate, a powerful oxidizer commonly used to make rocket and missile fuel as well as explosives. This is U.S. 5th Fleet’s first ever interdiction of ammonium perchlorate.
“This was a massive amount of explosive material, enough to fuel more than a dozen medium-range ballistic missiles depending on the size,” said Vice Adm. Brad Cooper, commander of U.S. Naval Forces Central Command, U.S. 5th Fleet and Combined Maritime Forces. “The unlawful transfer of lethal aid from Iran does not go unnoticed. It is irresponsible, dangerous and leads to violence and instability across the Middle East.”
The search also found more than 100 tons of urea fertilizer. Urea is a chemical compound with agricultural applications that is also known for use as an explosive precursor.
The vessel and its four Yemeni crewmembers were intercepted while transiting from Iran along a route historically used to traffic weapons to the Houthis in Yemen. The direct or indirect supply, sale or transfer of weapons to the Houthis violates U.N. Security Council Resolution 2216 and international law.
U.S. forces sank the vessel Nov. 13 in the Gulf of Oman after determining it was a hazard to navigation for commercial shipping. The four crewmembers were transferred to Yemen for repatriation Nov. 15 when The Sullivans completed an at-sea exchange in the Gulf of Aden with the Yemen Coast Guard.
“Alongside our partner forces, CENTCOM is committed to security and stability of the region and to deterring the illegal and destabilizing flow of lethal material into the region over land, in the air, and the sea,” said Gen. Michael “Erik” Kurilla, U.S. Central Command (CENTCOM) commander.
U.S. 5th Fleet previously seized 40 tons of urea fertilizer Jan. 18 when guided-missile destroyer USS Cole (DDG 67) and patrol coastal ship USS Chinook (PC 9) interdicted a another fishing vessel in the Gulf of Oman that had attempted to smuggle illicit weapons off the coast of Somalia months earlier.
The U.S. 5th Fleet operating area includes 21 countries, the Arabian Gulf, Gulf of Oman, Red Sea, parts of the Indian Ocean and three critical choke points at the Strait of Hormuz, Bab al-Mandeb and Suez Canal.
Recent successes include the U.S. Naval Research Laboratory’s (NRL’s) new program, called Proteus, to identify, query and filter maritime vessels based on user-defined criteria and the Defense Innovation Unit’s (DIU’s) international competition, known as xView3, to create machine learning models to locate and distinguish maritime vessels with synthetic aperture radar.
“Artificial intelligence combined with satellite imagery provides a new capability to detect suspected IUU fishing vessels that may otherwise elude U.S. and partner nations fisheries enforcement agencies. This increased maritime domain awareness can be shared with like-minded partner nations to enable them to protect their sovereignty.”
The NRL’s Proteus software, pictured, monitors sea vessels so stakeholders can “collaboratively discover and investigate suspicious and illegal maritime activity throughout the world in ways never before possible,” said Cameron Naron, the U.S. Maritime Administration’s maritime security director.
“PROTEUS is an exciting new U.S. government Maritime Domain Awareness (MDA) system providing a powerful array of MDA information and analysis tools,” said Cameron Naron, Director of Maritime Security, US Maritime Administration. “This system enables MDA stakeholders to collaboratively discover and investigate suspicious and illegal maritime activity throughout the world in ways never before possible.”
Additional actions supported by PROTEUS include: Counter Illegal, Unreported, and Unregulated Fishing (IUUF)
Maritime Protected Areas (MPAs)
Search and Rescue (SAR)
Critical Infrastructure Protection
Environmental Protection & Response
Maritime Law Enforcement
Counter smuggling (drugs, weapons, money, people)
This could be of assistance to any nation attempting to counter Illegal, Unregulated, Unreported fishing, including the island nations of the Western Pacific, who are desperately short on resources to monitor their ocean assets.
MarineLink reports that the Naval Surface Warfare Center Dahlgren Division has been working on high power microwave systems as a way to stop no compliant vessels, and they want the Coast Guard to try it out.
“We are looking to provide the U.S. Coast Guard with an HPM system for a one-year operational utility assessment,” said Pete Cacciola, a project lead for vessel stopping efforts in the HPM Weapon Systems Division. “Our goal is to give them another tool in their toolbox for noncompliant vessel interdiction.”…HPM weapon systems, a type of directed energy weapon system, operate by generating and transmitting extremely high electrical power levels, focused on specific frequencies and directed by steerable antenna systems. The result to a target is disruption or destruction of key components, rendering the target inoperable with little or no effect on personnel.

Below is a press release from Defense Visual Information Distribution Service (DVIDS). The boarding team was apparently Coast Guard. It’s likely the Webber class WPCs assigned to PATFORSWA will be doing this sort of work since the Navy PCs are being decommissioned.
U.S. 5th Fleet ships seized approximately 1,400 AK-47 assault rifles and 226,600 rounds of ammunition from a stateless fishing vessel during a flag verification boarding in accordance with customary international law in the North Arabian Sea, Dec. 20.
U.S. Navy patrol coastal ships USS Tempest (PC 2) and USS Typhoon (PC 5) found the weapons during a search conducted by embarked U.S. Coast Guard personnel. The illicit weapons and ammunition were later transported to guided-missile destroyer USS O’Kane (DDG 77) where they await final disposition.
The stateless vessel was assessed to have originated in Iran and transited international waters along a route historically used to traffic weapons unlawfully to the Houthis in Yemen. The direct or indirect supply, sale or transfer of weapons to the Houthis violates U.N. Security Council Resolutions and U.S. sanctions.
The vessel’s five crew members identified themselves as Yemeni nationals and will be returned to Yemen.
After removing the crew and illicit cargo, U.S. naval forces determined the stateless vessel was a hazard to navigation for commercial shipping and sank it.
U.S. naval forces regularly perform maritime security operations in the Middle East to ensure the free flow of legitimate trade and to disrupt the transport of illicit cargo that often funds terrorism and other unlawful activity. U.S. Navy warships operating in the U.S. 5th Fleet region have seized approximately 8,700 illicit weapons in 2021.
Guided-missile cruiser USS Monterey (CG 61) seized dozens of advanced Russian-made anti-tank guided missiles, thousands of Chinese Type 56 assault rifles, and hundreds of PKM machine guns, sniper rifles and rocket-propelled grenade launchers from a stateless vessel transiting the North Arabian Sea in May.
In February, guided-missile destroyer USS Winston S. Churchill (DDG 81) seized a cache of weapons off the coast of Somalia, including thousands of AK-47 assault rifles, light machine guns, heavy sniper rifles, rocket-propelled grenade launchers and crew served weapons. The inventory also included barrels, stocks, optical scopes and weapon systems.
The U.S. 5th Fleet area of operations encompasses approximately 2.5 million square miles of water area and includes the Arabian Gulf, Gulf of Oman, Red Sea, parts of the Indian Ocean and three critical choke points at the Strait of Hormuz, Suez Canal and Strait of Bab al Mandeb.

CIMSEC has what I believe could be a significant proposal for how the Americas could respond to the large fleets of fishing vessels that present a threat of Illegal, Unregulated, Unreported fishing that can overwhelm the resources of the individual nations. The US Coast Guard recently assisted Ecuador in monitoring one of these fleets.
The author suggests that collective action could be taken under the Inter-American Treaty of Reciprocal Assistance (commonly known as the Rio Treaty, the Rio Pact, the Treaty of Reciprocal Assistance, or by the Spanish language acronym TIAR from Tratado Interamericano de Asistencia Recíproca), perhaps modified as necessary, but he also notes that it already includes this provision,
“…Article 11 mentions how “the High Contracting Parties recognize that, for the maintenance of peace and security in the Hemisphere, collective economic security for the development of the Member States of the Organization of American States must also be guaranteed.” It goes without saying that economic security for coastal nations includes the fishing industry.
What typically happens is that a huge international fleet will follow the fishery. Most will be in international waters, but at least some may be tempted to enter the EEZ of coastal states. This year we have seen them move from off Ecuador, past Peru, down to Chile, and they are expected to transit to waters off Argentina. The size of the fishing fleet may successively overwhelm fisheries enforcement resources of these individual countries, but a collaborative approach could allow more effective enforcement.
The author refers to the US Coast Guard Shiprider Program as a model of how cooperative enforcement might work. Enforcement operations could be conducted under the authority of a representative of the nation whose resources are under threat.
Since the threat is primarily to violations of the Exclusive Economic Zone there would be no need for these collaborating units to even enter the territorial sea of the country under threat.
If such a collaborative operation is successful in the Americas, it could serve as a model for enforcement off Africa and Southeast Asia, leading perhaps to regional Combined Maritime Security Task Forces.

The U.S. Coast Guard Cutter Bertholf pulled into Sasebo March 3 following a deployment in the East China Sea where the crew assisted in United Nations Security Council Resolutions (UNSCR) enforcement against illicit ship-to-ship transfers that violate North Korea sanctions.
Thought something unusual was going on when Bertholf departed. Plus we have the Commandant’s Thursday State of the Coast Guard address is to include, “Coast Guard deployments to the western Pacific Ocean in support of U.S. national security and foreign policy objectives.”
Note, Bertholf was enforcing sanctions in the East China Sea. It may have been less upsetting to China that this was being done by a white hull, than by a gray hull with a Coast Guard detachment on board. Probably the same would be true about upsetting the Russians on the Eastern side of the Peninsula.

“We need to move from ‘luxury-car’ platforms—with their built-in capabilities—toward dependable ‘trucks’ that can handle a changing payload selection. “
–
He suggested that the Navy needs F150 pickups rather than Ferraris. Metaphorically the Webber class could be the Navy’s small Toyota pickup–cheap, reliable, versatile, and economical to operate.
–
A strong point for the Webber class is that it is probably the smallest and cheapest combatant, being currently manufactured, that can self deploy anywhere in the world (other than the polar regions) with minimal support en route as demonstrated by their self deployment to Hawaii and Alaska and USCGC Olivier F. Berry (WPC-1124)’s successful patrol to the Marshall Islands, 2200 miles from her homeport in Honolulu.
–
As currently equipped there is not a lot of free space apparent on the Webber class, but removing the eight meter “over the horizon boat” would free up a large area where mission modules could be placed. We can think of it as the bed of the pickup.

Potential Missions
Countering the Swarm:
The Navy’s most likely first use of a Webber class could be as replacements for the Cyclone class in South West Asia. Countering the large number of Iranian fast inshore attack craft (FIAC) is a mission the Cyclone class is expected to do now, protecting both larger Navy vessels and the tanker traffic that must pass through the Straits of Hormuz.

An earlier post, “Modifying Webber Class Cutters for Duty in SW Asia,” was aimed at this threat as applied to the Coast Guard Webber class that will be going to Southwest Asia. As a minimum the Navy will likely want some form of guided weapon, Perhaps the APKWS would suffice, if provided in sufficient numbers.

The 25mm Mk38 Mod2/3 that are currently mounted on the Webber class might be up-gunned (30, 35, and 40mm guns are all possible) and the mount might also be modified to also launch APKWS. Alternately the Mk38 might be replaced by BAE’s 40mm/70 MK4 and the Toplite gun director c(urrently mounted on the Mk38) could be mounted on the mast to control the 40mm, as the Israelis have done with some of their installations of the system, assuming the 40mm Mk 4 does not weigh too much.
BAE Bofors 40mm/70 mk4
Optimally, the outfit should include Longbow Hellfire. It could probably be mounted as single tube launchers affixed along the sides of the superstructure. I have seen a mockup of such a launcher. The missile itself is only about seven inches in diameter. If willing to replace the boat with missiles, its likely Lockheed could produce a 12 round launcher based on half the launcher being installed on the LCS.

Anti-Ship:
In other theaters there is likely a desire to have a larger anti-ship missile.
The Navy has been talking a great deal about “Distributed Lethality.” The concept has its origin in a January 2015 US Naval Institute article by then-Director of Surface Warfare Requirements (OPNAV N96) Rear Admiral Tom Rowden, RAdm. Peter Gumataotao, and RAdm. Peter Fanta.
Rowden’s co-author and successor at N96, Rear Admiral Pete Fanta, continued the drum beat with the memorable phrase, “if it floats, it fights,” suggesting that anti-ship missiles should be put on virtually all units.
–
On the Webber class, this would most likely the Naval Strike Missile (NSM), recently chosen by the Navy to arm its LCSs and frigates. A four cell launcher could probably replace the boat. The missile is only 13 feet long.

A new missile, “Deepstrike,” is being developed for these launchers. “The missile will be able to strike targets up to 309 miles away with precision, including moving targets both on land at sea.” (see also)
A Webber class equipped with these could function in the same way as the Army and Marine vehicles operating in the littorals and many river systems. Targeting would be provided by offboard sensors through networking.

Anti-Submarine Warfare (ASW)
–
This is probably unlikely, but there might be a place for craft that could perform ASW patrols off ports and amphibious objective areas or around choke points.
TRAPS containerized active/passive towed array from GeoSpectrum Technologies.
I have looked at how we might add torpedo tubes to the Webber class that could launch ASW torpedoes, but it is more likely aircraft, most likely helicopters, would be called in to make the actual attack. The ship would be primarily a sensor node, minimizing the requirement to keep ASW Helicopters airborne.
–
–
120mm Mortar for Naval Surface Fire Support:
–
Another truck like use would be to add this containerized large mortar as a way to provide naval fire support. This weapon is not currently in the US inventory but it does look promising. Guided projectiles are being developed for the 120 mm mortar.
–
Security for MSC’s PrePositioned Afloat Fleet
I am not sure what precautions the Navy has made to protect the ships of the MSC’s PrePositioned Afloat Fleet, but if I were an enemy there are might be strong incentive to destroy these ships that transport the most ready reinforcements of heavy equipment.
Webber class PCs might have a role in protecting these.
Large Unmanned Surface Vessel.
The Navy is seeking to procure a medium unmanned surface vessel (MUSV), 12 to 50 meters in length. The Webber class might be the basis for such a vessel. The modular systems described above might also be used on the MUSV.
–
Visit, Search, Board, and Seizure:
This is the mission these little ships are built for and, consequently, no change may be necessary. The mission might be stopping and boarding hundreds of small craft as was done off Vietnam as part of Operation Market Time, or it might be enforcing a blockade against Chinese shipping at the Straits providing access to the South China Sea. If resistance is expected there are a number of ways the vessels’ armament could be augmented, including missiles or torpedoes, but in most cases its likely air or backup could be called in. The real advantage is that the Navy would not need to tie down DDGs doing this work, and potentially risk it being damaged by improvised weapons on a vessel being boarded. For more challenging assignments two or three could be teamed with one or two providing boats and boarding teams and the other as a weapons carrier.

(Same video is available there, but the meeting does not actually start on that version of the video until minute 36.) There you can also find the written statements of the other three witness who constituted the second panel. The Commandant was the sole witness on the first panel.
This was something of a love fest for the Coast Guard with repeated praise for the people and actions of the Coast Guard.
This hearing was reputedly about how the Coast Guard had been impacted by the unusually severe Hurricane season. There is not a lot new here but there were some interesting remarks.
Polar Icebreaker Contracts
The intention is to Contract for the first Icebreaker and then employ block buy for the next two (28m). To me this seems to negate most of the advantage of a block buy. I don’t believe we will or should buy one and then wait until we have tried it out before contracting for the next two. That would necessitate a delay of at least five years during which we would still have the nightmare scenario of our only heavy icebreaker having no rescue if it should break down in the ice–certainly not an impossibility even with a new ship. If we are going to contract for the remaining two before testing the first, we might as well block buy all three.
First of class is always the most expensive. If the shipyard gets a block buy they know that initial improvements in productivity can be amortized over the entire block buy quantity. In some cases, in order to win the whole project, the shipyard will cut the price of the first ship substantially knowing they will make a profit over the entire project.
If we buy one and then block buy the second and third, we have paid for improvements to the winning yard with the first contract and minimized the chances for a competitive bid for numbers two and three.
Legislation has capped DOD participation in icebreaker procurement, so the bulk of icebreaker procurement costs will come out of the Coast Guard budget.
Authorization
There was a lot of discussion about the need to have the Coast Guard Authorization Bill signed into law, still not approved. You can see it here.
Other topics
There was a discussion of the high cost of the Coast Guard response to the recent series of Hurricanes.
Representative Sullivan spent a lot of time, discussing and advocating for an eleven mile road from King Cove (population estimate–989) to Cold Bay, Alaska (population estimate–122) which has an all-weather airport with two runways, one 10,180 feet and one 6285 feet in length. The Coast Guard connection is that the road would minimize or eliminate the necessity for the Coast Guard to Medivac emergencies from King Cove by helicopter, which is frequently hazardous. It is a Federal issue, because the road would run through a Federal reserve. The Commandant fully supported the desirability of completing the proposed single lane gravel road as a means of minimizing the requirement for helicopter medivac.
Video Breakdown
28m Domestic icebreakers–Design work on new domestic icebreakers is expected to start in 2030. That sounds a bit late to me. Mackinaw was commissioned in 2006 so if that is what he is really talking about, that makes sense, but the 140 foot icebreaking tugs are a different story. The first for of these will be 51 years old in 2030. More than half of them have already completed in-service which was expected to add 15 years to their service life. Morro Bay, at least, is expected to reach the end of her service life in 2030, and considering how long it takes us to build a ship we really need to start the process not later than 2025.
45m Western Pacific Fisheries Protection–They have not seen much risk of Illegal, Unregulated, or Unreported fishing.
