The Sentinel-class is suddenly everywhere

Posted on by 2 comments

The Coast Guard’s very successful Fast Response Cutter (FRC) program, the 154-foot Sentinel-class patrol craft, just keeps ticking along, with lots of important milestones this month. It makes you wish the Navy could get on board with a similar shipbuilding impetus.

50th Delivered

Bollinger Shipyards in Lockport, Louisiana– builder of the 110-foot Island-class and 87-foot Maritime Protector class patrol boats for the Coast Guard going back some 35 years– on 4 August delivered their 176th hull to the service, the future USCGC William Chadwick (WPC-1150). Chadwick, as the hull number points to, is the 50th FRC delivered since the first, USCGC Bernard C. Webber (WPC-1101), was contracted in September 2008. All in all, not a bad record for just under 14 years.

Based on the Dutch Damen Stan 4708 patrol vessel, the Coast Guard expects to order 64 of the increasingly useful vessels.

At a cost of about $65 million for each hull, the entire program of record is set to come in at under $4 billion which sounds like a lot but keep in mind the Navy has sunk nine times that much, over $36 billion, into the Littoral Combat Ship program already (even with the “cost savings” of decommissioning ships only a few years old, hyping that each LCS hull costs $70 million per year to keep in the water).

Besides a 25mm MK 38 Mod 2 forward, the FRCs have at least four mounts for M2 .50 cals, a decent C4ISR suite for their size, a 28-knot flank speed, and the capability to sortie over 2,000 nm on a two-week patrol without refueling or re-provisioning. They also have a stern launch and recovery ramp for a 26-foot, over-the-horizon interceptor cutter boat.

Set to be commissioned at her new home port at Ketchikan in September, the future USCGC Douglas Denman (WPC-1149), the Coast Guard’s 49th Fast Response Cutter, traveled nearly 7,000 miles from the most southeastern city in the U.S. to the most southeastern city in Alaska, transiting through the Caribbean Sea, the Panama Canal, and up the west coast of Central America and the U.S. in a 36-day voyage.

After delivery from Bollinger, FRCs and their plankowner crews spend almost two months at Key West where there is no shortage of missions in the Florida Straits on which to sharpen up.

From the 17th Coast Guard district on that process:

Following production of the ship in 2020, the first crewmember arrived in Ketchikan summer of 2021. Since then, the crew has undergone a year of administration and training in preparation to take ownership of the cutter. The engineering department alone attended a total of three months of school in addition to the crew’s seven weeks of familiarity training in Lockport, La., and seven weeks of Post Delivery Availability phase in Key West, Fla.

Full FRC six-pack in the Middle East

On 23 August, USCGC John Scheuerman (WPC 1146) and USCGC Clarence Sutphin Jr. (WPC 1147), joined four other examples of the newest Sentinel-class fast response cutters as part of the Coast Guard’s long-standing Patrol Forces Southwest Asia (PATFORSWA), stationed in Bahrain where U.S. 5th Fleet is headquartered.

The two FRCs completed a 10,000-nautical-mile transit to Bahrain, escorted by 270-foot medium endurance cutter USCGC Mohawk (WMEC-913), which acted as a mothership, rather than having to be loaded as float-on cargo.

The Coast Guard has been using more of these mini surface action groups (or “Surface Asset Group” in USCG parlance), such as in the response to 2017’s Hurricane Maria in Puerto Rico and you can easily imagine such white-hulled SAGs in the event of a conflict.

Scheuerman and Sutphin were met by two other FRCs of the Coast Guard’s Persian Gulf squadron– USCGC Glen Harris (WPC 1144) and USCGC Emlen Tunnell (WPC 1145)— flying their characteristic oversized U.S. ensigns, for a great photo op through the Straits.

Harris and Tunnell only recently arrived in Bahrain themselves, joining USCGC Robert Goldman (WPC 1142) and USCGC Charles Moulthrope (WPC 1141), to retire the six aging Reagan-era Island-class cutters that had been there since 2002 in support of Operation Iraqi Freedom.

Besides their stabilized MK 38 25mm gun and half-dozen (up from four as seen on stateside FRCs) M2 mounts, the Sentinels in Bahrain are equipped with the CG-HALLTS system, a hailer that has laser and LRAD capabilities, as well as a special S-band Sierra Nevada Modi RPS-42 pulse doppler with full-time 360-degree coverage, and other goodies to include four dedicated Long Range Acoustic Devices (LRADs) on the O-1 deck. Additionally, the already experienced cutter and boarding crews of PATFORSWA have to go through 5-6 weeks of Pre Deployment Training (PDT) with the service’s Special Mission Training Center at Camp Lejune and undergo more training once they reach Bahrain.

Hosting RIMPAC Marines ISR team

Finally, it should be pointed out that the FRC USCGC Cutter William Hart (WPC 1134)— who has been working with embarked teams of Hawaii-based Marines for intelligence, surveillance, and reconnaissance tests in the littoral since 2021– apparently did more of the same in the recently-concluded RIMPAC exercises.

Hart has been very active in presence missions in Oceania, recently completing a 10-day voyage to Samoa last winter in Operation Kurukuru and then operating alongside ships from the U.S., Australia, New Zealand, and France to combat illegal, unreported, and unregulated fishing (often from Chinese trawlers) in the region while on a 39-day patrol— which is a long time to spend on a 154-foot ship.

Still, they are getting it done and on the cheap at that.

7,000 Miles on a 154-foot Patrol Boat

The Coast Guard is really stretching the legs on their new Sentinel (Webber)-class Fast Response Cutters, especially in parts of the Pacific that may become very interesting in the coming years. Just 154-feet long overall and powered by an economical diesel suite, these vessels are a hair smaller than the Navy’s Cyclone-class PCs which are typically just assigned to coastal ops in the Persian Gulf region (a role the USCG is likely to take over once the Cyclones are retired).

One FRC just clocked 7K miles in a 39-day patrol. Sure, sure, it wasn’t an unbroken 39 days underway, but still, that’s some decent mileage on a small hull, especially on an operational cruise. Further, the patrol targeted IUU fishing, a big bone of contention with China and a legitimate cause of international heartburn in the Pacific with Bejing seen as a bully by many small Oceanic countries in the region, especially when you take the “Little Blue Men” of China’s Maritime Militia into account. 

Via the USCG PAO:

HONOLULU — The crew of the Coast Guard Cutter William Hart completed its 39 day patrol over 7,000 nautical miles in Oceania in support of the Coast Guard’s Operation Blue Pacific, last week.

Operation Blue Pacific is an overarching multi-mission Coast Guard endeavor promoting security, safety, sovereignty, and economic prosperity in Oceania while strengthening relationships between our partners in the region.

“This patrol had multiple goals which really displayed the adaptability of our crew,” said Lt. Cmdr. Cynthia Travers, the commanding officer of the William Hart. “While we continued to support international efforts to combat illegal, unreported, and unregulated (IUU) fishing in the region, we’ve also worked with our partners including New Zealand’s National Maritime Coordination Centre (NMCC), the nation of Samoa, the National Park Service, and the National Oceanic and Atmospheric Administration (NOAA) on a number of joint endeavors.”

In November the crew of the William Hart, one of the Coast Guard’s new Fast Response Cutters, participated in the Pacific Islands Forum Fisheries Agency’s (FFA) Operation Kurukuru, an annual coordinated maritime surveillance operation with the goal of combating IUU fishing.

IUU fishing presents a direct threat to the efforts of Pacific Island Countries and Territories (PICTs) to conserve fish stocks, an important renewable resource in the region.

Following the successful conclusion of Operation Kurukuru, the William Hart’s crew continued to patrol the Exclusive Economic Zones (EEZs) of the United States, Samoa, Tonga, Kiribati and Fiji to prevent illicit maritime activity.

Upon request from NOAA, the crew visited Fagatele Bay in the National Marine Sanctuary of American Samoa, using the cutter’s small boat to ensure there was no fishing or activity which would damage the coral within the United States’ largest national marine sanctuary.

The crew of the William Hart also supported a National Park Service boat during a transit between Tutuila Island and the Manu’a Islands, providing search and rescue coverage.

The cutter’s crew then departed for Fiji’s EEZ, where they supported New Zealand’s NMCC by locating an adrift Deep-ocean Assessment and Reporting of Tsunamis (DART) buoy and reporting the buoy’s condition to Headquarters Joint Forces New Zealand and other stakeholders.

DART buoys are real-time monitoring systems strategically deployed throughout the Pacific to provide important tsunami forecasting data to researchers.

“These expeditionary patrols are important to the continued stability and prosperity of Oceania,” said Lt. Cmdr. Jessica Conway, a Coast Guard 14th District operations planner. “Partnerships are key to promoting a free and open Indo-Pacific. Operation Blue Pacific allows us to coordinate with regional partners and most effectively employ our assets towards shared goals.”

Birddogging Chinese AGS 

 
In related news from the West Pac, the Coast Guard responded to a request from the Republic of Palau pursuant to the U.S.-Palau bilateral law enforcement agreement– one of 11 bilateral law enforcement agreements with Pacific Island Countries and Territories throughout Oceania– to assist with locating the Chinese-flagged research vessel Da Yang Hao (IMO: 9861342, MMSI 413212230) and observe its activity.
 
Owned by the China Ocean Mineral Resources R&D Association, the ship’s main purpose is prospecting for mineral resources, but it has the equipment useful in making the kind of accurate seabed charts needed by submarines to operate safely in the area of seamounts. Of note, Palau is important for vital maritime prepositioning assets of the MSC, which would be a ripe target in the opening 24 hours of a China-US conflict. 
 
The 4,600-ton vessel entered Palau’s EEZ on Nov. 29. On Nov. 30, the Coast Guard’s Joint Rescue Coordination Center (JRCC) Honolulu received a notification from the Palau Division of Maritime Security that the Da Yang Hao was observed north of Kayangel State within Palau’s EEZ without proper authorization. 
 

Via Naval News 

 
JRCC Honolulu deployed a Coast Guard Air Station Barbers Point HC-130 Hercules aircraft to locate the research vessel and confirm the vessel was not in distress given its varying course and minimal speed while operating in the Palauan EEZ.
 
The USCG Herky bird arrived on scene and located the research vessel approximately 100 nm WNW of the main Palauan island of Babeldaob transiting at slow speeds eastbound.
 
The Da Yang Hao communicated to the Hercules aircrew via radio that they were conducting storm avoidance. A subsequent overflight the following day relocated the research vessel transiting slowly north approximately 190 nautical miles northwest of the islands, approaching the limits of Palau’s EEZ.
 
This is where we should point out that the 14th Coast Guard District recently welcomed their first new HC-130J Super Hercules long-range surveillance aircraft this summer. The older HC-130Hs at the station are being replaced with the more capable Super Hercules aircraft; the current schedule has a fleet of four HC-130Js in Barbers Point by the end of summer 2022. These Herks have a new 360-degree, belly-mounted, multimode surface search radar and other bonuses not seen on the older aircraft.
 

The HC-130J features more advanced engines and propellers, which provide a 20% increase in speed and altitude and a 40% increase in range over the HC-130H Hercules. Another notable difference is the liquid oxygen system, which allows crews to fly at higher altitudes, providing a better vantage point for many missions. These aircraft have a modernized glass cockpit, the capability to execute GPS approaches, and are outfitted with the Minotaur Mission System Suite, which provides increased capabilities for use of the sensors, radar and intelligence-gathering equipment.
