The tired crew of the 154-foot Sentinel (Webber)-class fast response cutter USCGC Myrtle Hazard (WPC 1139) returned home to Guam last week, capping a 5,380nm expeditionary patrol that lasted just under a month (17 November to 14 December) under Operation Blue Pacific. Of that, 15 days were dedicated to” providing a persistent presence in the exclusive economic zones of the Federated States of Micronesia and the Republic of Palau.”

They also conducted five community events, including a volleyball game with locals, swimming lessons for children, and tours of the cutter.

“The patrol went beyond simple transit. It focused on building maritime security, engaging directly with Pacific partners, and enforcing international maritime law through shared operations,” notes the service.

Keep in mind that the FSM and Palau are being highly courted by Chinese interests, as are just about every island chain between Guam and the Philippines and Australia and Taiwan. So this is truly a hearts and minds mission in addition to showing the flag.

That’s why the two dozen Coasties aboard the 154-footer are punching above their weight class.

Hazard is the 39th FRC, named in honor of the first enlisted woman in the U.S. Coast Guard who served as an electrician and radio operator in the Great War.

She is one of three cutters of her class currently based in Guam and arrived there five years ago, replacing two aging 110-foot Island-class WPBs.

USCG Ups 154-foot Cutter Buy to 77 Hulls, PSU Boat Raiders, and HITRON Marks 1,000 ‘kills’

Posted on by Leave a comment

The Coast Guard’s 2004 Program of Record for its planned Sentinel-class Fast Response Cutter (FRC) program was “24 to 36 hulls.”

That was then.

Envisioned to replace 49 aging 110-foot 1980-90s vintage Island class patrol cutters (WPBs), 12 of which had been ruined in a botched lengthening modification, the new ships would be 30 percent longer, at 154-feet, and nearly twice the tonnage.

110-foot Island class cutters compared to the new 154-foot Sentinel (Webber) class FRCs

Powered by two 5,800 shp MTU diesels (double the plant of the 110s), the FRCs also had 50 percent greater unrefueled range (2,900nm vs 1,882nm), a much better cutter boat (a stern dock launched jet drive 26-footer vs a davit deployed 18-footer with an outboard), better habitability, sensors, commo, and better guns (a gyro-stabilized remote fired Mk 38 Mod 2/3 25mm with an EO/IR sensor system and 4-6 M2s/Mk19s vs an unstabilized eyeball-trained Mk 38 Mod 0 and two M2s).

Plus, they had larger crews, at 4 officers, 4 POs, and 16 ratings, vs 2/2/12, which meant more hands could be sent away on landing details.

This meant they would be rated as WPCs instead of WPBs, akin to the Navy’s similar 170-foot Cyclone-class PCs.

The lead FRC delivered, USCGC Bernard C. Webber (WPC-1101), commissioned in April 2012, while the last 110s to leave Coast Guard service did so this summer, at which point the FRCs, which have proven extremely handy, even on long-ranging blue water cruises in the Pacific, had 58 hulls in service with another nine under contract.

A big jump from 24-36!

The truth is, the USCG is pressing these new 154-footers into the gap left by their aging 210-270-foot blue-water medium-endurance cutter fleet. Mission whackamole.

Classmember USCGC Oliver Berry (WPC-1124) completed a nearly 9,300-nautical-mile, 45-day round-trip patrol from Hawaii to Guam in 2020 and followed it up with a 46-day patrol in 2024. At the same time, several of these hulls are self-deploying 7,700 miles from Key West to new home ports in Alaska.

There have been repeated calls for the Navy to purchase members of the class for use in littoral operations, as the cutter has sufficient weight and space to mount a Naval Strike Missile box launcher with four tubes at the stern.

Now, the CG has upped the $65 million per-cutter Sentinel class program to 77 hulls, with a 10-ship buy announced this week.

“Since its introduction to the fleet in 2012 as the successor to the 110-foot Island class patrol boat, the Fast Response Cutter has consistently proven its capabilities, adaptability, and effectiveness in a wide range of maritime environments and Coast Guard missions,” said RADM Mike Campbell, the Coast Guard’s Director of Systems Integration and Chief Acquisition Officer.

PSU Boat Raiders!

As part of Arctic Edge 2025, an element of 3rd Bn, 4th Marines, 1st MARDIV teamed up with Long Beach, California-based USCGR Port Security Unit 311 to use their 32-foot Transportable Port Security Boats to conduct a boat raid on a “simulated enemy port” at Port Mackenzie, Alaska.

A sort of budget SWCC/SEAL kind of arrangement.

The SWCC we have at home, if you will.

Keep in mind that something like this could be in the toolbox in a future conflict.

Capable of 45 knots on a pair of inboard diesels, the TPSBs carry two .50 cals and two M240B GPMGs. Girded with ballistic panels, they have shock-mitigating seats and can carry as many as eight passengers in addition to a four-man crew. It looks like each carried a half-squad or so of Marines. Each PSU has six TPSBs, allowing a theoretical raid force of 72, exclusive of crews.

The boats have an over-the-horizon capability and range of 238nm, meaning they can be used as an easily deployable blocking/interdiction force in a littoral if needed.

HITRON hits 1K

Finally, the U.S. Coast Guard’s Jacksonville-based Helicopter Interdiction Tactical Squadron (HITRON) achieved a significant milestone in its counter-drug mission, completing its 1,000th interdiction of suspected narco-trafficking vessels on 25 August.

Since its founding in 1999, HITRON has interdicted $33.2 billion in illicit drugs during operations in the Eastern Pacific Ocean and Caribbean Sea, and over the past 26 years, it has averaged one interdiction every nine days.

Not bad numbers for less than 200 Coasties, including reservists and auxiliaries, and a dozen MH-65E Dolphins, whose base airframes are 40 years old!

On Aug. 25, HITRON used airborne use of force to stop the non-compliant vessel, marking the unit’s 1,000th drug interdiction since the unit’s inception in 1999, which resulted in Midgett crew members seizing approximately 3,606 pounds of suspected cocaine worth an estimated $46 million and apprehending six suspected narco-traffickers.

Alaska USCG Ops Get Some Muscle

Posted on by Leave a comment

The Coast Guard, with 2,500 members assigned to USCG Arctic (formerly the 17th Coast Guard District), has been busy bird-dogging Chinese government research vessels in the region.

We’ve already talked about the China-flagged research ship Xue Long 2 (Snow Dragon 2), which, at 14,300 tons, is China’s first domestically built polar research vessel, poking around the Extended Continental Shelf a couple of weeks ago.

Now, four other Chinese red hulls are poking around as well.

The five Chinese Research Vessels are: Xue Long 2, China-flagged; Shen Hai Yi Hao, China-flagged; Zhong Shan Da Xue Ji Di, Liberia-flagged; Ji Di, China-flagged; and Tan Suo San Hao, China-flagged.

From USCG PAO Juneau: 

The U.S. Coast Guard detected and responded to two Chinese research vessels operating in the U.S. Arctic and is currently monitoring a total of five similar vessels in or near the U.S Arctic.

On August 5, a C-130J Hercules fixed-wing aircraft from Air Station Kodiak responded to the Chinese research vessels Ji Di and the Zhong Shan Da Xue Ji Di.  Both vessels were transiting northeast in the Bering Sea.

On August 6, the crew of U.S. Coast Guard Cutter Waesche (WMSL 751) again responded to the Zhong Shan Da Xue Ji Di as it was transiting north in the Chukchi Sea above the Arctic Circle, after passing through the Bering Strait.

The C-130 and USCGC Waesche were patrolling under Operation Frontier Sentinel, an operation that responds to adversaries operating in and around Alaskan and U.S. Arctic waters. The U.S. Coast Guard’s responses are intended to counter malign activities, defend sovereign interests, and promote maritime conduct consistent with international law and norms.

The presence of these vessels is consistent with a three-year trend of increased activity from Chinese research vessels operating in the U.S. Arctic. Last year, three Chinese research vessels conducted research operations north of the Bering Strait.

Storis commissioned in Juneau

The new (to the service) “icebreaker” USCGC Storis (WAGB-21) was commissioned in Juneau on Sunday.

U.S. Coast Guard Cutter Storis (WAGB 21) remains moored during the Storis commissioning ceremony at Juneau, Alaska, August 10, 2025. Storis is the first polar icebreaker acquired in more than 25 years by the Coast Guard, with its mission to assure access to the polar regions and protect U.S. sovereignty. (U.S. Coast Guard photo by Petty Officer 3rd Class Carmen Caver)

Taking the name of the legendary 2,000-ton/230-foot WWII-era icebreaker USCGC Storis (WAGL/WAG/WAGB/WMEC-38), which had a 64-year career, much of it in Alaska waters, the new 12,800-ton 360-foot cutter is much different but at the same time, more capable in many ways.

Sadly, although she was commissioned in Alaska and is to be stationed there, Storis will be shifting back to Seattle, where she is chilling with the USCG’s other icebreakers until a berth can be finished for her in 2026-27.

Meanwhile, the Coast Guard’s $4.3 billion Polar Security Cutter (PSC) heavy polar icebreaker program has had all three of its vessels fully funded— although it will probably be half a decade before the class leader is delivered and commissioned.

Going past that class, three to five new medium polar icebreakers called Arctic Security Cutters (ASCs) are on the drawing board, giving the service eight modern icebreakers to replace its current three (the 50-year-old heavy USCGC Polar Star, the 26-year-old medium breaker USCGC Healy, and the ersatz Storis).

$3.5 billion for the first three Arctic Security Cutters has been fully funded under H.R. 1.

New Sentinel clocks in

The fifth of six planned new 154-foot Sentinel (Webber) class Fast Response Cutters is slated to be commissioned at Kodiak’s fuel pier on Monday after self-deploying over 7,000nm from her builder in Louisiana.

Cunningham will be homeported in Kodiak with USCGC John Witherspoon (WPC 1158), which arrived in January. Meanwhile, they have a trio of Ketchikan-based sisters: USCGC John McCormick (WPC-1121)— the first Sentinel-class stationed in Alaska in 2017– USCGC Anthony Petit, and USCGC Bailey Barco. They all replaced smaller, cramped 110-foot Island-class cutters, which dated back to the Reagan Administration.  

The Coast Guard commissioned its newest cutter, Coast Guard Cutter Earl Cunningham (WPC 1159), for official entry into its service fleet during a ceremony held in Kodiak, Alaska, Aug. 11, 2025. The ceremony was presided over by Adm. Kevin Lunday, acting commandant of the Coast Guard, and members of the Cunningham family were also in attendance, including the cutter’s sponsor, Penney Helmer, who is also the granddaughter of Earl Cunningham. (U.S. Coast Guard photo by PA3 Carmen Caver)

Armament includes a Mk 38 Mod 2 25mm gun forward and four flex mounts for M2 .50 caliber BMGs (or anything else that can be put on those pintles) along with assorted small arms. These vessels have been operating small UAVs as of late.

The sixth FRC headed to Alaska, the future USCGC Frederick Mann (WPC 1160), was delivered by Bollinger last month and should arrive in Alaskan waters in the coming weeks.
With 67 FRCs contracted by the USCG, and six now serving in the Persian Gulf, the service is negotiating with Bollinger for another 10-to-12 of these hardy vessels.

Fresh 154 Action in Alaska

The 17th Coast Guard District is now just over halfway through its slow-motion upgrade from its squadron of elderly Reagan-era 110-foot Island-class patrol cutters to the much more capable new 154-foot Sentinel (Webber) class Fast Response Cutters.

The future USCGC John Witherspoon (WPC 1158) arrived at the cutter’s new homeport in Kodiak on Tuesday, following an unescorted 7,000-mile self-deployment from Key West.

(U.S. Coast Guard photo by Petty Officer 1st Class Shannon Kearney)

Witherspoon joins three Ketchikan-based sisters: USCGC John McCormick (WPC-1121)— the first Sentinel-class stationed in Alaska in 2017– USCGC Anthony Petit, and USCGC Bailey Barco— in Alaskan waters and will be the first of three of her class based at Kodiak.

Scheduled to be “officially” commissioned during a ceremony in April when things warm up, Witherspoon’s crew spent the past three months in shakedown and training in the Gulf of Mexico (America?). She is the 58th FRC delivered by Bollinger under the U.S. Coast Guard’s current program.

Armament includes a Mk 38 Mod 2 25mm gun forward and four flex mounts for M2 .50 caliber BMGs (or anything else that can be put on those pintles) along with assorted small arms. These vessels have been operating small UAVs as of late. 

As referenced by the builder:

FRCs have conducted operations as far as the Marshall Islands—a 4,400 nautical mile trip from their homeport. Measuring in 154 feet, FRCs have a flank speed of 28 knots, state of the art C4ISR suite (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance), and stern launch and recovery ramp for a 26-foot, over-the-horizon interceptor cutter boat.

Stacking the two classes against each other is dramatic.

The Coast Guard had a force of six 110-foot Island-class cutters stationed in Alaska in the late 1980s-2020s, of which two remain in service:

  • USCGC Liberty (WPB-1334) has spent her 33-year career at Juneau and Valdez.
  • USCGC Mustang (WPB-1310) has spent her 39-year career stationed in Seward.
  • USCGC Naushon (WPB-1311), which has been in Homer since 2016.

Legacy 110s on the Alaska beat included:

  • USCGC Anacapa (WPB-1335), which was decommissioned in 2024, spent 32 of her 34 years stationed in Petersburg, Alaska, and famously sank by NGF a Japanese “zombie trawler” a few years back that had drifted across the Pacific from Fukushima in 2012.
  • USCGC Farallon (WPB-1301), which was in Valdez from 2015 to 2019
  • USCGC Chandeleur (WPB 1319), which was at Ketchikan until decommissioned in 2021.
  • USCGC Sapelo (WPB-1314,) which was at Homer from 2015 to 2022.
  • USCGC Roanoke Island (WPB-1346,) which was at Homer from 1992 to 2015.

Four recently decommissioned CENTCOM Islands— ex-Adak (WPB-1333), Aquidneck (WPB-1309), Monomoy (WPB-1326), and Wrangell (WPB-1332)— were just handed over to the Greek Navy earlier this month.

A much smaller 87-footer, USCGC Reef Shark (WPB-87371), has been stationed in Auke Bay since 2022 while her sister, USCGC Pike (WPB-87365) is in Petersburg.

Coasties in New Places…and with new Cutters

Posted on by Leave a comment

Last week, the 154-foot Sentinel-class fast response cutter USCGC Frederick Hatch (WPC 1143), based in Guam, visited Tacloban in the Philippines on the occasion of the 79th Leyte Gulf Landing Anniversary while the larger frigate-sized USCGC Stratton (WMSL 752) called in Manila.

Hatch is the first of her class to visit the Philippines and will certainly not be the last as the FRCs are sailing far and wide, increasingly roaming around the West Pac. If you are curious, while calling at Tacloban she was 1,300 miles away from home, certainly within range as they have been logging patrols as long as 8,000nm in recent months. 

Colleagues from the Philippine Coast Guard prepare to receive the crew of the USCGC Frederick Hatch (WPC 1143) at the pier in Tacloban, Philippines, on Oct. 19, 2023. In a historic first, the USCGC Frederick Hatch (WPC 1143) visited Tacloban, Philippines, from Oct. 19 to 23, 2023, and the crew conducted engagements marking a significant milestone in the enduring relationship between the United States and the Philippines. (U.S. Coast Guard photo by Cmdr. Ryan Crose)

From the CG PAO:

“The expanded capabilities of the Fast Response Cutter represent more than just advanced technology; they symbolize the bridge of cooperation and goodwill between nations. The FRCs and their dedicated crews regularly play a pivotal role in international diplomacy. These vessels, along with their highly trained and professional crews, are ambassadors of peace and collaboration, said Capt. Nick Simmons, commander of U.S. Coast Guard Forces Micronesia/Sector Guam. “They foster understanding and trust across borders, making the seas safer not only for our own nations but for all nations that rely on the freedom of navigation and maritime security.”

Hatch is the 43rd FRC and was commissioned in July 2021, so she is a new hull.

The class has been around since 2012 when the leader, USCGC Bernard C. Webber (WPC 1101) was commissioned and sent to Miami.

Of relevance, the fourth of the class commissioned, USCGC Robert Yeard (WPC 1104) joined the fleet in 2013 and is currently out of the water at the CG Yard in Maryland where she is getting an overhaul, offering some great shots of her hull form.

As detailed by the cutter’s social media page:

Every three years the Yered gets hauled out for some much-needed maintenance including a top-end overhaul of the mains and a full paint job. For the next 140 days, it will be stripped, sprayed, welded, shafts and props dropped replaced, and cleaned. As hard as this ship works and runs, it needs it.

For reference, all of the FRCs are built by Bollinger in New Orleans and the current program of record is 65 hulls, although plans are for at least two to be placed in uncrewed a Recurring Depot Availability Program (RDAP)– otherwise known as “ordinary” back in the day, due to empty billets across the USCG. 

OPC Progress

Meanwhile, the future USCGC Argus (WMSM-915), the lead ship of the Heritage-class Offshore Patrol Cutter program and the sixth cutter to carry the name, is set to side-launch at Eastern Shipbuilding Group’s Nelson Shipyard near Panama City, Florida on Friday and proceed to finish fitting out in prep for commissioning.

The Heritage class is so-called as they are all to be named for historic cutters, a move I for one support and wish the Navy would take a hint when it comes to naming conventions. For example, the initial cutter Argus was one of the first 10 ships assigned to the U.S. Revenue Cutter Service, a predecessor service to the Coast Guard in 1791. Of the 10 original cutters assigned to the RCS, Argus spent the longest time in service. Subsequent cutters Argus were commissioned in 1804, 1809, 1830, and 1850.

Interestingly, the first OPC’s sponsor is not a politician but  Capt. Beverly Kelley, USCG, (Ret). She was the first woman to command an American military vessel when she was piped aboard the 95-foot Cape-class patrol boat USCGC Cape Newagen in 1979.

Kelly, a University of Miami alum who graduated from OCS in 1976, seen on Cape Newagen’s bridge back in the day when the USCG still allowed beards without a profile. She went on to skipper the 270-foot cutter Northland (WMEC-904) as well as the 378-foot cutter Boutwell (WHEC-719) before retiring in 2006, capping a 30-year career that included 18 in sea-going billets.

More on the Heritage (Argus) class

OPC Characteristics:
• Length: 360 feet
• Beam: 54 feet
• Draft: 17 feet
• Sustained Speed: 22 Plus knots
• Range: 8500 Plus nautical miles
• Endurance: 60 Days

The main armament is an Mk 110 57mm gun forward with an MK 38 25mm gun over the stern HH60-sized hangar, and four remote .50 cal mounts. 

I say replace the Mk38 with a C-RAM, shoehorn a towed sonar, ASW tubes, an 8-pack Mk41 VLS crammed with Sea Sparrows, and eight NSSMs aboard, then call it a day.

But no one listens to me…

Current spending on the overbudget and overtime project puts the ships at $704 million per hull. Hopefully, this can be amortized out now that a second yard (Austal in Mobile) is working on the cutters and a big reason why Eastern is so far behind is a mix of teething issues with the brand-new design (in particular non-compliant shafts delivered by Rolls-Royce for the first to hulls) and the 2021-22 supply chain/Covid slow down.

As the OPC program of record is for 25 cutters– replacing the smaller 13-strong Bear class and 16-member Reliance classes of cutters– and, knowing the Coast Guard will be the backbone of the force in blue water for the next 40 years, it is important to get it right.

Upsizing Bushmaster

Of interest to small boat naval gun guys is this notice from Thursday’s and Friday’s DOD Contracts announcements (emphasis mine):

MSI Defence Systems US LLC, Rock Hill, South Carolina, is awarded a $23,463,149 firm-fixed-price contract for the procurement of 15 MK88 MOD4 Gun Mounts, associated hardware, and spares. Work will be performed in the United Kingdom (90%) and Rock Hill, South Carolina (10%) and is expected to be completed by March 2025. Fiscal 2023 weapons procurement (Navy) funds in the amount of $11,621,453 (50%); fiscal 2023 shipbuilding and conversion (Navy) funds in the amount of $8,991,450 (38%); and fiscal 2023 weapons procurement (Coast Guard) funds in the amount of $2,850,246 (12%), will be obligated at the time of award and will not expire at the end of the current fiscal year. This contract was not competitively procured in accordance with 10 U.S. Code 3204(a)(1), (only one responsible source and no other supplies or services will satisfy agency requirements.) Naval Surface Warfare Center Indian Head Division, Indian Head, Maryland, is the contracting activity (N00174-23-C-0015).

MSI-Defence Systems US LLC,* Rock Hill, South Carolina, is awarded a $29,263,267 firm-fixed-price, indefinite-delivery/indefinite-quantity contract for the procurement of the MK 48 Mod 2 Electro-Optical Sight (EOS), EOS spare parts and transportation cases, and evaluation and repair of EOS subassemblies in support of the MK 38 Mod 4 Machine Gun System for the Navy, Coast Guard, and Military Sealift Command. Work will be performed in Norwich, United Kingdom (56%); and Rock Hill, South Carolina (44%), and is expected to be completed by September 2026. Fiscal 2023 weapons procurement (Navy) funds in the amount of $7,601,246 (57%); and fiscal 2023 shipbuilding and conversion (Navy) funds in the amount of $5,700,936 (43%), will be obligated at time of award; the funding will not expire at the end of the current fiscal year. This contract was not competitively procured via the sam.gov website, with one offer received. This is a sole source action in accordance with Federal Acquisition Regulation 6.302-1, only one responsible source. MSI-Defence Systems US LLC is the original equipment manufacturer of the systems and the only company who can provide the systems and perform the required evaluation and repairs. No other supplies or services will satisfy agency requirements. Naval Surface Warfare Center, Crane Division, Crane, Indiana, is the contracting activity (N0016423DJQ13).

MSI makes the MK38 Mod 4 on a standard M88 mount, perhaps the best version of the Bushmaster. Whereas the first version was crew-manned, this one is a “fully integrated Naval Gun controlled via a Combat Management System (CMS) or Electro-Optic Fire Control System (FCS) using a remote independent Electro-Optical Sight System (EOSS)” which really ups the hit factor.

Plus, rather than just a M242 25mm cannon, the Mod 4 carries the MK44S 30mm cannon with the option to coaxially mount the 12.7mm M2HB Heavy Machine Gun to the main gun, providing additional engagement capability.

The 30mm MK44S has 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size, making it a much more powerful option with a 4,000m range versus the 25mm’s 2,000m range.

The Mk 48 Mod 2 MSI-DS Electro-Optical Sight System (EOSS) includes long-range Day/Night All Weather sensors, has an auto-tracking mode for long endurance surveillance of targets, can be mounted on superstructure or mast positions, and interfaces with the ship’s Combat Management System or Integrated Bridge via existing common consoles or a standalone Remote Operator Console and HD display monitor. Plus, since it is not on the gun mount itself, it doesn’t spook those it observes. Meanwhile, as it is all-optical/IR it doesn’t light up a radar warning receiver/ECM set, which could be a nice benefit in ambush attacks

As for where they are going, the USCG has gone on record as saying they plan on mounting one or two of these on each of the new icebreakers (Polar Security Cutter) but, as these mounts are only negligibly heavier and fit the same footprint as earlier MK38s, there is a definite logic in mounting these on the 154-foot Sentinel (Webber) class Fast Response Cutters operating in the Persian Gulf and Western Pacific, swapping out the MK38 Mod 2s currently fitted on the bow. 

As 15 mounts are on order, maybe that is the plan…plus the MSC notation is very interesting.
