(I meant to cover this earlier, but perhaps still worth a listen)

CIMSEC’s Podcast “SEA Control,” had an interview with the Commandant, Dec. 27, 2020. You can find it here.

At first I thought I had heard it all before, but toward the end, there were some surprises.

He talked about  Arctic, Antarctic, and IUU. He talked about the Arctic Strategic Outlook and the IUU Strategic Outlook.

Illegal, Unreported, Unregulated fishing got a lot of attention. He related that it was gaining visibility and had become a national security issue since overfishing has created food security issues for many countries. He pointed to Coast Guard Cooperation with Ecuador in monitoring a fishing fleet off the Galapagos Islands. Internationally he sees a coordination role for the USCG.

Relative to the Arctic he mentioned the possibility of basing icebreakers in the Atlantic and the need for better communications.

He talked about the Tri-Service Strategy and the Coast Guards roles in it, particularly in less than lethal competition.

More novel topics started about minute 38 beginning with Unmanned systems. He talked about the recent CG experiments with unmanned systems and went on to note that the CG will also regulated Unmanned commercial vessel systems.

About minute 41 he talked about the Coast Guard’s role in countering UAS in the Arabian Gulf. He added that we have a lead role in DHS in counter UAS. “We are in the thick of that”

GA-ASI Concludes Successful Series of MQ-9 Demonstrations in Greece

He said the service was looking at MQ-9 maritime “Guardian” (minute 45)

When ask about reintroducing an ASW capability he said that while the Coast Guard was looking at it, the service would have to be cautious about biting off too much. (My suggestion of how the CG could have an ASW mission with minimal impact on its peacetime structure.)

He talked about balancing local and distant missions and concluded that the CG could do both (47), and that the Coast Guard was becoming truly globally deployable (48).

He noted that the first two FRCs for PATFORSWA would transit to Bahrain in Spring, followed by two more in the Fall, and two more in 2022. (49)

He noted technology is making SAR more efficient. “Hopefully we will put ourselves out of the Search and Rescue business.” 50

He talked about the benefits of “white hull diplomacy.” (52)

Asked about our funding for new missions he said it was sometime necessary to demonstrate the value of the mission first, then seek funding. (55)

He also talked about raising the bar on maintenance.

“RDC concludes Low Cost Maritime Domain Awareness Pilot Study” –CG-9

The 29RDC autonomous vessel underway during the Coast Guard’s unmanned surface vehicle demonstration Oct. 7 through Nov. 5 off the coast of Oahu, Hawaii.

Below is a story from the CG-9 website. It provides more specifics on the results than did my earlier post.

  • “…proved their capability to detect vessels in excess of a mile and in certain situations in excess of 4 miles.” That sounds a little disappointing, I would have expected more range, at least against larger targets.
  • “…the 29RDC was operated by RDC watchstanders in New London, Connecticut, demonstrating the vessel’s ability to be controlled from 5,000 miles away utilizing cellular service.” That would tend to indicate they were operated relatively close to shore.

Sounds like they learned a lot. The potential is there. It seems the Coast Guard spends very little on R&D. We probably ought to do more.


The Coast Guard Research and Development Center (RDC) Nov. 5 concluded a month-long evaluation of unmanned surface vehicles (USVs) to determine their ability to provide persistent maritime domain awareness (MDA) in remote areas of the ocean.

The focus of the evaluation was to explore how current and emerging technologies might support the Coast Guard’s many missions around the globe. The project showed that USVs with assorted sensor capabilities may be useful to complement organic Coast Guard aviation and surface assets in performing key operations in these regions, ranging from combatting illegal, unreported and unregulated (IUU) fishing to conducting search and rescue and a full range of law enforcement missions.

Initial results revealed that commercially available USVs are capable of delivering some level of daytime MDA and can conduct 30-day endurance missions. Two USVs used for this evaluation – the wind-propulsion Saildrone and Watcher, a diesel/solar-powered cutter boat from Spatial Integration Systems – proved their capability to detect vessels in excess of a mile and in certain situations in excess of 4 miles.

This demonstration also highlighted the importance of developing and incorporating artificial intelligence and machine learning into future USVs. The sensors used in this demonstration captured significant amounts of data. To speed processing and limit expensive bandwidth consumption, it is invaluable for the USV to conduct onboard processing to the greatest possible extent, limiting transmitted data to only that which is actionable to operators, according to Cmdr. Blair Sweigart, the RDC researcher who served as the demonstration director. He said this ability is critical to USVs’ success in long endurance and MDA missions.

“This evaluation showed that using autonomous USVs for future persistent MDA efforts will likely require a layered solution. USVs like Saildrone are capable of performing MDA missions for up to a year without maintenance, but their low transit speed does not allow them to pursue a target of opportunity to collect more information,” said RDC researcher Scot Tripp, who served as project manager. “In contrast, the Watcher is only capable of 30 days endurance but has the capability of traveling at speeds over 30 knots. It can also be instructed to pursue a target upon detection for better imagery. A system where these USVs worked together could prove to be a valuable tool for future MDA capabilities,” Tripp explained.

Two of the USVs used in this demonstration were contractor-owned/contractor-operated, which is only one of the potential procurement models available for these types of vessels. The type of vessel and how it is being used may best dictate which acquisition mode is most efficient, Tripp said. The Saildrone routinely operates on a service-provider model, for example, but government-owned/government-operated USVs might also be used effectively.

The RDC pursued the efficacy of a government-owned/government-operated USV with the 29RDC, a 29-foot autonomous vessel based on the Coast Guard response boat-small II. With the 29RDC, service operators from junior enlisted boat drivers to senior officers were able to interactively plan and execute their own missions in real time. Additionally, the 29RDC was operated by RDC watchstanders in New London, Connecticut, demonstrating the vessel’s ability to be controlled from 5,000 miles away utilizing cellular service. These demonstrations provided exceptional feedback regarding potential operations using USVs: in concert with cutters and other boats as a force multiplier; performance of reconnaissance missions; search and rescue augmentation through autonomously executed search patterns; and screening recreational and commercial vessel traffic.

This demonstration also reaffirmed a whole-of-government interest in enhancing MDA. Participants included U.S. Immigration and Customs Enforcement, U.S. Customs and Border Protection, Navy Research Laboratory, Office of Naval Research, National Oceanic and Atmospheric Administration, Scientific Advisors for the U.S. Navy, The President’s Intelligence Advisory Board and Congressional staffers.

The Coast Guard is also interested in USV testing to help better inform policy decisions as these vehicles become more numerous in the marine environment.

This demonstration was part of the Coast Guard’s pilot study of low-cost commercially available technologies that can enhance maritime domain awareness in Pacific regions, with the primary focus of monitoring (IUU) fishing.  A quick look report summarizing preliminary results from the demonstration can be found here. A full report is scheduled for completion mid-2021.

Below is a 14th District news release discussing a recent month long experiment with using unmanned surface systems for maritime domain awareness (MDA), particularly in regard to Illegal, Unregulated, Unreported (IUU) fishing. Sounds like they had some success.

“These vessels proved to be very effective across a variety of mission areas. The results of this study will help shape how the Coast Guard, and our partners, incorporate USVs into our future operations.”

Coast Guard completes 30 day test of unmanned surface vehicles off Hawaii

USV USV Test USV

Editors’ Note: Click on images to download a high-resolution version.

HONOLULU — The Coast Guard completed a 30 day demonstration and evaluation of unmanned surface vehicles (USVs) off Oahu, early November.

The focus of the test was to explore how current and emerging technologies might be used to enhance maritime domain awareness in remote regions. The test also showed ways USVs with assorted sensor capabilities might support the Coast Guard’s many missions around the globe ranging from search and rescue, to law enforcement.

“It’s clear that autonomous technology is a growing industry, and has great potential to enhance Coast Guard operations,” said Cmdr. Blair Sweigart, the demonstration’s director from the Coast Guard Research and Development Center. “Combined with artificial intelligence algorithms, unmanned systems could be a game changer.”

During the test the Coast Guard examined USVs from Saildrone and Spatial Integrated Systems to understand their capabilities and effectiveness. The USVs participated in a variety of operational simulations to detect and alert the Coast Guard to both legitimate and nefarious behavior.

As outlined in the Coast Guard’s Strategic Plan 2018-2022, one of the service’s main goals is to “evaluate emerging technologies, such as unmanned platforms, artificial intelligence, machine learning, network protocols, information storage, and human-machine collaboration for possible use in mission execution.”

These tests represent a commitment to those goals, allowing the Coast Guard to identify how USVs could be used to support search and rescue operations, improve Marine Environmental response, enhance Port Security, aid in the fight against illegal maritime smuggling, and identify vessels engaged in illegal, unreported, and unregulated fishing.

“The demonstration helped us understand what these technologies currently are, and are not, capable of,” said Sweigart. “These vessels proved to be very effective across a variety of mission areas. The results of this study will help shape how the Coast Guard, and our partners, incorporate USVs into our future operations.”

With their long endurance, USVs can provide persistent domain awareness in remote regions of the U.S. Exclusive Economic Zone. By conducting the demonstrations off Hawaii, the teams gained a firsthand understanding of how these assets could help protect the islands, and the critical resources and habitats throughout Oceania.

Many of the Coast Guard’s missions require close coordination with federal, state, local, and international partners and during the tests the Coast Guard worked closely with NOAA, DHS partners, the Navy, and agencies from several partner nations who face similar issues to protect the global maritime and fishing industries.

“Metal Shark and Sea Machines to Supply New U.S. Coast Guard Autonomous Test Vessel” –DefenseMediaNetwork

“The welded-aluminum 29 Defiant craft is the latest product of Metal Shark’s “Sharktech Autonomous Vessels” division to be equipped with Sea Machines SM300 autonomous-command and remote-helm technology. The new vessel offers a full range of advanced capabilities including transit autonomy, collaborative autonomy, active ride control and collision avoidance, and remote control vessel monitoring.”

DefenseMediaNetwork posted a story about the acquisition of an optionally manned surface vessel for the Coast Guard’s Research and Development Center.

During exercises scheduled for October off the coast of Hawaii, the RDC team will test and evaluate the Sharktech vessel’s autonomous capabilities for their potential in supporting USCG surveillance, interdiction, patrol, and other missions.

The July/August issue of the Navy League’s magazine Seapower included a lot of Coast Guard content. I will not try to cover everything included, much of which has already been covered here, but I will mention a few things that stood out for me.

The Commandant’s Interview:

There was an interview with the Commandant, Admiral Schultz, that I found most interesting. There was a fair amount of information that was new to me.

Icebreakers:

Perhaps most significant was a comment regarding the Medium icebreaker.

“We also are looking to build probably a medium breaker, potentially what we’re going to call the Arctic security cutter — a little less capability in terms of icebreaking, but that capability would get us back to being an Atlantic and Pacific icebreaker Coast Guard.(emphasis applied–Chuck)

It may be that, if this ship is intended to transit the St Lawrence Seaway and work part time in the Great Lakes, like Canada’s proposed six “Program Icebreakers,” it would preclude the option of simply building six Polar Security Cutters rather than the three heavy and three medium icebreakers called for in the High Latitude Study. Alternately we might have four heavy Polar Security Cutters (PSC) in the Pacific and two Arctic Security Cutters (ASC) in the Atlantic.

The interview goes on to state, referring to its planned five year long progressive service life extension program, “…we could keep the 44-year-old Polar Star around here probably through the end of the decade if things go well.” (emphasis applied–Chuck)

The Western Pacific:

The Commandant noted that the Coast Guard had advisers in the Philippines, Vietnam, Fiji, and that an additional adviser would go to Malaysia and an attache to Australia to work with Australia and New Zealand. That there would also be an advisor assigned to Guam to work with the Commonwealth of Micronesia and the Federated States of Micronesia.

The Coast Guard is becoming more involved in countering Illegal, Unregulated, and Unreported (IUU) fishing, and will be providing leadership in international forums.

In reference to the forthcoming Tri-Service Maritime Strategy the Commandant said we could expect, “…to see the Coast Guard bring some unique capabilities to that conversation, particularly in the Indo-Pacific region.” 

Unmanned Systems:

Regarding land based systems the Commandant noted, “..we’ve completed prototype deployment of ScanEagle in Puerto Rico and Texas.” and “We teamed with U.S. Southern Command and CBP and employed one of those (MQ-9–Chuck) in an operation out of Panama that proved tremendously successful.”

He also mentions the possibility of using UAS of all sizes and mentioned the possibility of unmanned surface systems as well.

Cyber:

Sighting the FY2021 budget, Admiral Schultz said, “That is one of the biggest growth areas for humans in the Coast Guard here in the past budget cycle or two. There is somewhere north of 150 additional cyber warriors in the budget before the Congress right now.” 

“Insitu’s ScanEagle Performs ISR for Coast Guard”

There is a short one page report on the use of ScanEagle. It notes that ScanEagle is currently installed on six National Security Cutters and will be installed on all NSCs.

“A standard pack-out for a deployment of three ScanEagle UASs. The sensor systems include an electro-optical/infrared camera, a laser pointer, a communications relay, an automatic identification system (AIS), and visual detection and ranging (VIDAR)–a surface search capability.”

Interesting that it includes a laser pointer on the Coast Guard aircraft because that is usually used as a designator for laser homing weapons.

“The Era of the New Cutters”

This was a three page story, most of which is familiar to regular readers of this blog, but there was one nugget I had not seen before. “…the Coast Guard still will need to pursue a service-life extension program on six of the ships to ensure sustained fleet capability until the OPC program is finished.”

This almost certainly refers to the service life extension program (SLEP) for 270 foot WMECs. This is, I believe, the first time I have seen a number of ships mentioned, so not the whole class of 13. Notably it is only six so don’t expect a SLEP for 210s. They will soldier on in their current configuration until their long delayed retirement.

“GeoSpectrum Launches Low Frequency Active VDS Deployable by USVs”

Geospectrum’s new, compact version of the Towed Reelable Active Passive Sonar (TRAPS) suitable for Unmanned Surface Vessels (USVs)

NavyNews reports that Canadian Company GeoSpectrum has developed a version of their “Towed Reelable Active Passive Sonar” (TRAPS) that is scaled to fit vessels as small as 12 meter Unmanned Surface Vessels (USV).

We talked earlier about an earlier version of this system. If it fits on a 12 meter (39’4″) USV, then it should certainly be able to fit on anything WPB or larger. If we should ever have to go to war, this might be a capability we would want to protect our harbor approaches from submarines. We would probably also want to add an ASW torpedo launching capability.

It might be worth doing some experimentation to see how it works, and if desirable, draw up plans for adding this or a similar system for mobilization. First of course we should take a look at the results of Canada’s tests.

Might also be desirable to have something like this for the Webber class cutters going to PATFORSWA, since the Iranians have a large number of small conventionally powered submarines.

Maybe it could help us find semi-submersibles smuggling drugs as well. 

A Successful Test of TALONS and an Air Droppable Rescue Boat

There are two items of interest here.

Naval News brings us more news about TALONS and incidentally, info on an air droppable rescue boat. We have been following DARPA’s development of TALONS (Towed Airborne Lift of Naval Systems) for about four years.

Putting sensors at 1000 feet gives a horizon distance of 38.7 miles compared with 8.7 miles for a more typical height of 50 feet. This latest test show how truly small the footprint of this system can be. The boat is only 15’8” (4.8M) in length.

I had never heard of the Greenough Advanced Rescue Craft (GARC). Apparently it is a standard Air Force system. The Coast Guard used to have a capability to drop a lifeboat from a fixed wing aircraft. The Air Force apparently still does and it looks like it could be remote controlled to go to the rescue of those in distress. Check out the description in at the link below.

“The Unmanned GARC is 15’8” (4.8M) in length and a full load displacement of 3,600lbs. It has a top speed in excess of 35 knots, a range of 400+ nautical miles at 30 knots (700+ nm range at 6 knots). It can operate up to sea state 4.”

When we used to do this (even before my time), I am pretty sure the survivors had to make their way to the boat, which could be problematic. Looks like this one could be driven to the survivors and probably has a radio link.

Sea-Air-Space 2019 Virtual Tour

Like most of you I did not make it to the Navy League’s 2019 Sea-Air-Space Exposition, so I have found some YouTube reports that can at least provide some of the information passed along at the event. The descriptions below each video are from the YouTube description.

Sea Machines, Hike Metal to Collaborate on SAR Autonomy” –MarineLink

Marine Link reports an attempt to build an unmanned rescue vessel.

Boston-based Sea Machines Robotics announced today a new partnership with Hike Metal, a world-class manufacturer of workboats based in Ontario, Canada, to integrate Sea Machines’ SM300 autonomous vessel control system aboard commercial vessels tasked with search-and-rescue (SAR) missions.

Unmanned is “all the rage,” but once you get on scene, you never know what you will find. The victim you are attempting to help may need medical assistance, they may not be able to move to shelter provided by the boat.

Automated systems could operate like a smart cruise control on your car, navigating to a designated position and even follow the rules of the road. Automated systems can reduce manning requirements, but when the SAR vessel gets on scene, you need the versatility of a human being to respond to the unexpected.

(Writing this feels some how wrong. Am I being reactionary? Isn’t this obvious to everyone? Still felt like I had to say something. Good systems could come out of this, but full autonomy is just too much to expect.)

Webber class Could be the Navy’s Light Duty Pickup Truck

In 2012 the US Naval Institute published an important article by then CNO Admiral Johnathan Greenert, “Payloads over platforms: Charting a new course.” It starts off, 
“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.

The test marked the first vertical missile launched from an LCS and the first launch of a missile from the SSMM from an LCS. (Photo by U.S. Navy)

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.

Missile Truck
The Army and Marines have tracked and truck mounted missile launchers. 
 
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. 
The Canadians have a small containerized towed array sensor that looks like it would fit.

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.
