Icebreaking research vessel
MOL is to deploy an outfitting crew to the shipyard building Japan’s first icebreaking research vessel

Marine Log reports,

JAMSTEC (Japan Agency for Marine-Earth Science and Technology) has taken another step forward on the build of Japan’s first research vessel with icebreaking capabilities. The icebreaking research ship is on order at Japan Marine United’s Isogo shipyard in Yokohama where, as of last month, the design of the hull structure was nearing completion…The LNG dual-fueled Polar Class 4 ship will have a total length of 128 meters, a width of 23 meters, an international gross tonnage of about 13,000 tons, and a crew of 99 people. It will be to break sea ice with a thickness of 1.2 meters at a speed of 3 knots, and will be equipped with drones, unmanned probes, and Doppler radars used for weather observations.

That is 420 feet in length and 75’5” in beam. USCGC Healy is the same length, but 82′ (25 meters) in beam, and 16,000 tons, so they are pretty close. If I interpreted correctly, this would be considered at the low end of the medium icebreaker class by the USCG. Like Healy, this ship uses shaft driven propellers.

There are diagrams of the ship here.

How Bofors 57 mm Mk3/Mk110 Naval Gun Reload Works –Video

Thought this video was interesting enough to pass along.

This makes it clear why the nominal “220 round per minute” rate of fire for the 57mm Mk110 is only good for short periods. There can be up to 120 rounds on the mount but there may be interruptions to reload after 20 or fewer rounds. Frequently different types of ammunition are loaded in the left and right sides of the mount ammunition feed system, so there may be only 60 or fewer rounds of a particular ammunition type on the mount.

The linked information above includes a note for the 57mm Bofors 57 Mk2 which appears to share the same reload mechanism as the Bofors 57mm Mk3 (Mk 110 in US service) “Time to reload 120 rounds: 2 minutes”. It appears reloading the two 20 round ready service cassettes that move with the gun requires the gun to at or near maximum elevation. It is not clear if partially filled ready service cassettes can be topped off, I would hope that would be the case. The time to elevate, reload and return to firing position could be critical. Hopefully you will not wait until all 120 rounds on the mount are expended before reloading.

Thanks to Lee for bringing this to my attention.

“Coast Guard completes work on service life extension program prototype” –CG-9

Coast Guard Cutter Harriet Lane departs Coast Guard Yard in Baltimore Aug. 3, 2023, after undergoing 15 months of In-Service Vessel Sustainment Program production work. The service life extension program for this cutter entailed 113 work items, worth $21 million, which included a new electrical system and an MK38 Mod 3 gun weapon system, a first for the medium endurance cutter class. Both Coast Guard Cutters Seneca and Harriet Lane served as medium endurance cutter prototypes for new electrical and structural work and Harriet Lane served as the gun weapons systems prototype.

For more information: In-Service Vessel Sustainment Program page

Above is an announcement by the Acquisitions Directorate (CG-9). As I noted in a July post about the WMEC270 Service Life Extension program, there are still some unknowns regarding the program. The photo above may answer some of those questions.

As expected, a Mk38 gun mount has replaced the 76mm Mk75. The CG-9 post indicates the installed mount is the 25mm Mk38 Mod3, and that there is one and only one mount. The Mk92 fire control system has apparently been removed and I see no apparent new radar that would replace its air search and approach control capability. It also appears the SLQ-32 has been removed.

It appears the Mk38 Mod3 is mounted on an elevated platform about four feet above the foc’sle deck. This should provide both a better field of fire and a degree of protection from green water coming over the bow, though I felt it should have been raised a full deck.

Harriet Lane was a prototype, but it wasn’t one of the six to get the complete SLEP. They are to be Spencer, Legare, Campbell, Forward, Escanaba and Tahoma.

Harriet Lane is expected to change homeports to the Pacific and be dedicated to operations in the Western Pacific.

I think it perhaps unfortunate, that the ship that may be placed in a position where it will need to face down China Coast Guard cutters armed with 76mm guns has lost hers. Perhaps it should not matter, but it may be more difficult to act boldly when your adversary can hurt you badly, from a distance, with impunity.

“The Coast Guard is investing in underway connectivity…and it’s paying off!” –MyCG

Below is news from MyCG. I am publishing it in full for convenience. It is a great advertisement for Starlink which has played a significant role in Ukraine’s Maritime Drone offensive against Russia, but the most surprising thing for me was this,

“…soon all users will have Dial-In Phone System (DIPS), a new capability that assigns a unique telephone number to every member of the workforce to last for the duration of their career. With it, you will be able to make and receive phone calls, and have voicemail, within DoD365 Teams….even underway! (Watch out for another MyCG article next week for more information about DIPS!)”

WOW!!

The Coast Guard is investing in underway connectivity…and it’s paying off!

By AJ Pulkkinen, MyCG staff writer

The Coast Guard is aggressively adding Starlink commercial satellite communications on most cutters. This next-generation upgrade provides a twenty-fold increase in the speed of shipboard networks.

The C5I team already installed Starlink on 17 cutters and targets all major cutters (WMSL, WMEC, Polars) for completion by the end of this calendar year (CY) WLB (225s) and FRC (154s) are targeted during CY24, along with the 17 WPBs (87s) that have installed legacy commercial satellite communications.

Starlink technology provides the bandwidth and latency for shipboard users that is on par with those working at a desk in an office ashore.

Bandwidth and latency are two different aspects of network performance. Bandwidth is the amount of data that can be transferred over a network for a definite period of time. Latency is the amount of time it takes for a bits of data to travel from one point on a network to another.

Underway users already equipped with Starlink are experiencing drastic increases in connection capability, such as connectivity to CG applications including Direct Access, FSMS, SharePoint, OneDrive and the full suite of DOD365 apps, and the ability to seamlessly upload and download large media files.

Starlink’s performance more easily allows underway users to access personal email, banking and social media. And soon all users will have Dial-In Phone System (DIPS), a new capability that assigns a unique telephone number to every member of the workforce to last for the duration of their career. With it, you will be able to make and receive phone calls, and have voicemail, within DoD365 Teams….even underway! (Watch out for another MyCG article next week for more information about DIPS!)

Starlink also provides global coverage, notably in the high latitudes. The cutter Eagle experienced minimal to no loss in coverage while crossing the North Atlantic to the Azores. Capt. Jessica Rozzi-Ochs says, “Starlink has seamless transition from satellite to satellite, unlike the legacy system, which drops service while it looks for and tracks a new satellite. This was particularly impressive when we experienced heavy weather (20+ foot seas, hard rain, 40-50 knots of wind) and Starlink didn’t go down once.”

Gone will be the days of having to come back to port only to spend hours or days at the computer because you lacked connectivity while underway.

The Eagle’s crew reported great success with their Starlink. By having consistent access to the Financial System Management Solution (FSMS), Eagle’s supply office reduced the number of offline requisitions, which minimized human error in tracking commitments and expenditures underway. They were able to better communicate with vendors and partners, streamlining the acquisition processes and coordinating port services for their port calls. With this enhance communication, they procured parts essential for maintaining the cutter fully mission capable even when short turnaround times were necessary.

The Eagle’s crew was able to frequently upload pictures and video to social media accounts in near-real time while underway. These timely posts reached a wide audience, with several posts reaching over 45,000 views.

Starlink will help alleviate one of the greatest burdens on our cutter community: intermittent connectivity. This capability will transform shipboard life, and serve as an invaluable tool for recruitment, retention, and the sea duty attractiveness.

“USNI News Fleet and Marine Tracker: Aug. 14, 2023” –USNI

The US Naval Institute News Service “Fleet Marine Tracker” continues to report atypical Coast Guard activities. It continued to report on USCGC Healy’s Arctic deployment and mentioned PATFORSWA as they have since they have since they began including Coast Guard units in May.

This week, they included some activity I have not seen reported elsewhere.

“Legend-class National Security Cutter USCGC Munro (WMSL-755) departed Fleet Activities Yokosuka (CFAY) and is now in South Korea.”

“Coast Guard Cutter Forward (WMEC-911) is currently supporting Operation Nanook. Operation Nanook is an annual Canadian-led exercise that fosters international cooperation and shared responsibility in the Arctic and the northern Atlantic Regions.”

The USCGC Bear (WMEC-901) and allied ships from Canada, Norway, France, and Denmark steam in formation in the North Atlantic Ocean during last year’s Operation Nanook in August 2022. 

“U.S.-Philippine Coast Guard Patrols: Time To Provoke the Provocateur” –Real Clear Defense

Real Clear Defense has a post by the J. C. Wylie Chair of Maritime Strategy at the Naval War College, Dr. James R. Holmes, discussing the implications of the planned Philippine/US Coast Guard joint patrols in the South China Sea.

It is a thought-provoking article but I would argue for a change of emphasis. The Chinese consider what is happening war without gunsmoke, but if we engage on that basis we are already at war. Rather I would suggest we see this as purely law enforcement vigorously applied–which is of course the reason it is the US Coast Guard rather than the USN that will be conducting these joint patrols.

  • If foreign vessels fishing in the Philippine EEZ without a license is not already illegal, make it so. The Philippines should make sure the Chinese know that is how it will be viewed and act accordingly.
  • No foreign vessels should be allowed to impede Philippine vessels conducting legal activities.
  • No foreign vessels should be allowed to exploit the resources of the Philippine EEZ without a license.
  • No foreign vessels should be allowed to damage resources in the Philippine EEZ.

The Chinese maritime militia has been very useful, but they may also be viewed as China’s weakness, since they are officially civilians. As civilians violating Philippine law, they should be subject to vigorous law enforcement action.

If a vessel chooses to block a Coast Guard vessel and violates the Rules of the Road in the process, if a collision results and their engineroom floods, it was their violation of the Rules of the Road that caused the collision.

This is lawfare, not warfare, and the law is on the side of the Philippines. The Chinese are acting as a gang of thieves stealing from their weaker neighbors. Diplomatically the US and the Philippines need to work toward something similar to the Combined Maritime Forces organization in SW Asia and fielding a law enforcement alliance like my proposed Combined Maritime Security Task Force Pacific. (“Combined” used this way means multi-national.)

“Defending the Dutch Caribbean: An Assessment” –Geopolitical Monitor

Posted on by

Willemstad, Feb. 2022. The Netherlands the royal family was transported from Aruba to Curacao aboard the Holland-class offshore patrol vessel HNLMS Holland (P-84).

Geopolitical Monitor discusses the six islands of the Dutch Caribbean, part of the Kingdom of the Netherlands.

The Netherlands has been a good partner in drug interdiction operations in the Caribbean. The four ships of the Holland class are in many ways similar in size and characteristics to the Offshore Patrol Cutters. The Netherlands Navy tends to keep one of these ships in the Caribbean, and they frequently host US Coast Guard Law Enforcement teams. At least once they also hosted a Coast Guard H-65 airborne use of force helicopter.

The post talks about the Dutch Caribbean Coast Guard (DCCG, or Kustwacht Caribisch Gebied: KCG),

“…which has facilities in Aruba, Curaçao, and Sint Marteen. This agency carries out missions involving search and rescue, law enforcement, and maritime interdiction. The DCCG’s fleet includes three Damen Stan Patrol 4100 cutters (slightly smaller but similar to the Webber class–Chuck), Jaguar, Panther, and Puma, five Boston Whaler Justice 20 craft, and 12 Metal Shark Defiant interceptor vessels. In addition, in April 2022, the Dutch organization for defense equipment (Defensie Materieel Organisatie) announced that two helicopters were acquired from Bristow Helicopters and will be delivered in 2023. The DCCG currently operates two DHC-8 aircraft and two AgustaWestland AW139 helicopters.”

They even have had long range, medium altitude unmanned search aircraft assigned, something the US Coast Guard still does not have,

“The DCCG’s surveillance capabilities were expanded in late March 2022, with the arrival to Curaçao of three General Atomics MQ-9A Reaper unmanned aerial vehicles and two ground stations. The Reapers assist Dutch Caribbean military personnel in combating organized crime and illegal fishing, among other activities. They will remain in Curacao until 1 July 2023.”

The post alludes to Venezuelan’ threats to Dutch Caribbean islands that lay off the Venezuelan coast (Aruba, Curaçao, and Bonaire). While the Venezuelan military is far more powerful than the forces the Netherlands keeps in the Caribbean, it is hard to take these threats seriously since, an attack on even one of the islands, would be an attack on NATO.

On a personal note, really enjoyed a stopover in Aruba in the early 80s while it was snowing back in our Portland, Maine homeport–my wife will never let me forget.

“US to Deploy Coastguard Ship to Papua New Guinea” –The Defense Post

The USCGC Oliver Henry (WPC 1140) crew arrives in Manus, Papua New Guinea, on Aug. 14, 2022, from Guam as part of a patrol headed south to assist partner nations in upholding and asserting their sovereignty while protecting U.S. national interests. The U.S. Coast Guard is participating with partners to support the Pacific Islands Forum Fisheries Agency-led Operation Island Chief and the larger Operation Blue Pacific through patrols in the Western Pacific in August and September 2022. (U.S. Coast Guard photo by SW3 Victor Villanueva, NMCB-FOUR)

(Sorry, this is a couple of weeks old.)

The Defense Post reports,

US Defense Secretary Lloyd Austin on Thursday announced the deployment of a US Coastguard ship to Papua New Guinea, as Washington seeks to boost its military footprint in the region amid fierce competition for influence with China…“A US Coastguard cutter will be here in August,” Austin said as he became the first Pentagon boss to visit Papua New Guinea.

Again, the Coast Guard is being used as an instrument of foreign policy. That is not a bad thing, but it is a fact.

It is not like the Coast Guard has not been there before. The photo is from 2022, but the US and Papua New Guinea are seeking closer, mutually beneficial ties.

For Papua New Guinea this means improvements to dual use (military and civilian) infrastructure (ports and airfields), increased economic activity, and help with preventing IUU fishing.

For the US, the diplomatic activity is prompted by Chinese attempts to obtain influence in Oceania that seemed to have been demonstrated when the Soloman Islands failed to respond to a request for a routine replenishment stop for USCGC Oliver Henry (pictured above).

“INSIDE LOOK aboard HMCS Harry DeWolf” –Video

Just a short video, made at least a couple of years ago, but particularly wanted to feature the “cable deck,” time 1:27 to 1:45, where you see mooring and anchoring gear conspicuously missing from the foc’sle. Keeping this gear inside the ship is critical to keeping it operational in the Arctic environment.

A total of eight ships of the class are planned, six for the Canadian Navy and two for their Coast Guard. Navy or Coast Guard, these “Arctic Offshore Patrol Ships” (AOPS) essentially perform what we view as Coast Guard missions. They are 6,615 ton ships, 340 feet (103.6 meters) in length. Four diesel generators provide power to two electric motors that provide 12,000 HP for a 17 knot max speed. Range is 6,800 nautical miles at 14 knots. The crew is 65 with accommodations for 87. The gun seen in the video is a weatherized version of the 25mm Mk38. They are Polar Class 5.

Damage Resulting from Ukrainian USV Attacks –The Drive

Posted on by

The Drive provides information showing the results of Ukrainian Unmanned Surface Vessel (USV) attacks on a small Russian tanker and a Russian Navy LST. Reportedly the USVs were equipped with 450 kg of explosives (about 1000 pounds). The explosions occurred essentially at the waterline. Had the explosions occurred well below the waterline, or particularly below the keel, the effect would have been greater. Even in the photo above, it appears the explosion cause more damage below the waterline than above. Had it been well above the waterline, the effect on the ship would probably have been less, but similar sized bomb or missile hits on the superstructure would likely have caused more personnel casualties.
