Fast Response Cutter / Navy MkVI Patrol Boat –Peter Ong

Today we have a guest author, Peter Ong. This is Peter’s sixth post on this blog, and he is now a regular contributor to Naval News. In this post, he reports a conversation with Coast Guard Cutter Forces about why the success of the Coast Guard’s Fast Response Cutter program has allowed  the Navy to cancel their MkVI patrol boat program that at one time was expected to produce 48 patrol boats.

The MkVI had only very austere galley and messing facilities, a Microwave and MREs. They were not expected to be underway more than 24 hours. The FRCs endurance, allowing days, rather than hours, on station to intercept drug and arms smugglers and their abilitiy to support counter UAS systems may be providing capabilities the MkVI simply could not have.

When is a ship a boat and when is a boat a ship? When is an apple an orange and when is an orange an apple? Answer: they are not as these are two different and distinct things when it comes to comparing the warships of the U.S. Coast Guard to the MkVI patrol boats of the U.S. Navy.

The U.S. Navy is divesting of their 12 in-service Mark VI Patrol Boats, which at the Surface Navy Association 2021, Major General Tracy King, USMC, Director, Expeditionary Warfare (N95) stated that the twelve Mark VIs “Were very expensive to maintain.” However, many critics and pundits of the Mark VIs’ early retirement cite that the Mark VIs still have a lot of life left in them and that their high speeds and heavy armament makes them an asset to special forces, Marines, and Navy SEALs. Mark VIs also perform capital ship escort screenings and contribute to Distributed Lethality and Distributed Maritime Operations by having a smaller vessel signature that might help U.S. Marines move around and slip ashore undetected.

In a phone interview on September 29, 2022 with United States Coast Guard (USCG) Captain John J. Driscoll, Office of Cutter Forces (CG-751), the U.S. Coast Guard captain made a comment about the Sentinel-class Fast Response Cutters (FRC) substituting for the U.S. Navy’s Mark VI Patrol Boats in the Patrol Forces Southwest Asia (PATFORSWA) region and other parts of the globe.

The U.S. Navy plans to replace the Mark VIs and the aging Patrol Coastal boats in the PATFORSWA region with USCG FRCs. When asked how the cutter fleet is integrated with the U.S. Navy and the Department of Defense, the captain replied that the cutter fleet is built into different operational security plans within the U.S. Department of Defense, but these plans are not discussable.

Captain Driscoll said that the Coast Guard’s Fast Response Cutters and the Mark VI are different assets and have different capabilities. The 65 planned FRCs have much greater range and greater endurance (5 days, 2,500 nautical miles (4,600 km; 2,900 mi) and are designed to be on patrol 2,500 hours per year) than the U.S. Navy’s Mark VI Patrol Boats (750 nautical miles (860 mi; 1,390 km) at 25 knots; 690 nautical miles (790 mi; 1,280 km) at 30 knots).

The captain mentioned that the FRC is tremendously capable and different in how it integrates with the Department of Defense and one can’t make comparisons between the Navy’s Mark VI and the USCG’s Fast Response Cutters because the FRC is a commissioned warship of the United States with an assigned crew whereas the Mark VI is just a patrol boat—a ship versus a boat—the ship is larger. The FRC is 154-feet long (46.9 m) with a beam of 25-feet (7.6 m) whereas the Mark VI Patrol Boat is 84.8-feet (25.8 m) long with a beam of 20.5-feet (6.2 m).

Armament is about the same between the two vessels (a Mark 38 MOD 2 25mm autocannon forward with crew-served 12.7mm heavy machine guns and grenade launcher(s) aft) with the Mark VI sporting more armament (another potential Mark 38 25mm autocannon aft and potential crew-served 40mm automatic grenade launchers or 12.7mm heavy machine guns. Some PATFORSWA FRCs will receive the Mark 38 MOD 3 with a 7.62mm coaxial chaingun to the bow 25mm autocannon and a 40mm automatic grenade launcher).

Nonetheless, one can see the huge difference in operational range. Furthermore, the success of the 65 planned Coast Guard FRCs eclipses the 12 Mark VI U.S. Navy Patrol Boats in terms of production numbers. Furthermore, the Mark VI is propelled by waterjets to 45 knots (52 mph; 83 km/h) whereas the FRC has propellers that drive it at 28+ knots. Repeated requests to the U.S. Navy asking for explanation on “[The Mark VIs are] very expensive to maintain” were not answered, but one can assume that it takes a lot of time, labor, and money to clean out the Mark VI’s waterjet intakes and impellers compared to the more easily accessible external shaft and propellers on the Fast Response Cutters when operating in littoral waters potentially teeming with flotsam and seaweed.

FRC range and endurance are important. Captain Driscoll stated that the FRCs are working in the Papua New Guinea and Indonesian region to combat Illegal, Unreported and Unregulated (IUU) fishing and are working with partner nations to address the competition for maritime resources.

As for possible up-arming of the FRCs with the Mark 38 MOD 4 30mm autocannon, that is a retrofit possibility, noted the captain, although the upcoming Polar Security Cutter (PSC) heavy icebreakers will receive the 30mm autocannons first, two on each PSC. Captain Driscoll mentioned that the 30mm autocannon is in the U.S. Navy acquisition system and that the USCG and U.S. Navy both decide on future cutter armament. Programmable and airbursting 30mm ammunition options are not discussable although if the U.S. Navy has the specialized and advanced 30mm ammunition in its inventory, the USCG can also use it depending on the cutter’s mission parameters.

“All American Marine wins order for 74-foot patrol vessel” –Marine Log

California Department of Fish and Wildlife vessel will feature Teknicraft rapid RHIB launch and retrieval system, integrated into the stern

Marine Log reports,

“The California Department of Fish and Wildlife (CDFW) has awarded Bellingham, Wash., based All American Marine Inc. (AAM) a contract for the construction of an aluminum catamaran patrol vessel…Measuring 74 foot long by 27.5 feet wide…The design integrates a Teknicraft hull shape…complemented by Teknicraft’s signature integration of a wave piercer that is positioned between the catamaran sponsons to break up wave action and ensure reduced drag while conducting research missions.”

I did an 2019 post on the Texas Parks and Wildlife patrol boat this craft is based on. Notably that craft was designed to patrol up to 200 nautical miles offshore. A foil between the catamaran hulls reportedly reduces resistance and improves fuel economy.

Notably All American Marine is doing service life extension (SLEP) work on Coast Guard 47 foot MLBs.

Thanks to Lee for bringing this unconventional design to my attention. 

“Laser-Guided Rockets Are Getting New Highly-Versatile Anti-Armor Warhead” –The Drive

The Drive reports on a test of a new warhead for the “Advanced Precision Kill Weapon System” (APKWS)

The Advanced Precision Kill Weapon System, or APKWS, laser guidance kit designed by BAE Systems has been tested in a surface-to-surface role with a new highly versatile, multi-purpose warhead that is capable of taking on armor and other targets. The new warhead is provided by General Dynamics Ordnance and Tactical Systems. The test demonstrated added flexibility for not only the APKWS itself, which is most often employed in air-to-ground applications against more lightly armored targets, but also for all platforms that are capable of firing APKWS rockets.

The test also demonstrated a new launcher.

The report was quite complete, providing background and an update on the entire program.

If you have been reading this blog regularly, you know I think APKWS would be a good fit for the Coast Guard as a precision weapon that would be highly effective against small, fast, highly manueverable threats while minimizing the possibility of collateral damage. Its relatively new proximity fuse also makes it effective against Unmanned Air Vehicles which appear to be an emerging threat. APKWS might even be effective against small ships if used in quantity.

For larger threats Hellfire or its replacement, JAGM, would be a better choice, but because this is so much cheaper and available in larger quatities, it appears much more likely. APKWS would probably be a better choice for PATFORSWA where the threat includes large numbers of small craft and UAVs.

We may have seen the video below, but it does suggest that the system is suitable for the 85 foot Navy MkVI patrol boat, so its certainly suitable for cutters of similar size and larger.

“Ukraine’s New U.S. Supplied Combat Boats Already Patrolling Black Sea” –Naval News

Metal Shark 40 Defiant

Naval News reports,

6 U.S. Navy type patrol vessels have recently been supplied to Ukraine. These are already active in the Black Sea where they face a much more powerful adversary in the Russian Navy. But the Ukrainian Navy is building a reputation as an effective asymmetric force.

These are the same 44 foot patrol boats the Navy has been buying.

A bitter sweet day. End of an era. The last of six Island class cutters assigned to PATFORSWA is now decommissioned. The force has now been reequipped with six Webber class Fast Response Cutters.

U.S. Coast Guard decommissions Bahrain-based USCGC Baranof

U.S. Coast Guardsmen conduct a decommissioning ceremony for USCGC Baranof (WPB 1318) in Manama, Bahrain, Sept. 26, 2022.

MANAMA, Bahrain — The USCGC Baranof (WPB 1318) was decommissioned during a ceremony aboard Naval Support Activity Bahrain, Monday.

Vice Adm. Kevin Lunday, commander of U.S. Coast Guard Atlantic Area, presided over the ceremony.

“USCGC Baranof’s exemplary service to our nation is a testament to both the Island-class platform and the crews that have manned Baranof over the past 34 years,” said Lunday. “Whether it was conducting law enforcement and search and rescue in the Caribbean, or deploying to the present-day homeport of Bahrain to support U.S. Central Command, those that have manned Baranof have continually met the needs of America.”

Baranof was commissioned into service on May 20, 1988 at Coast Guard Base Miami Beach in Miami. The 18th of 49 Island-class patrol boats, Baranof received orders to the U.S. Fifth Fleet area of operations in support of Operation Iraqi Freedom in 2002. Shortly after their arrival in Bahrain, Baranof’s crew was underway conducting maritime interdiction operations in the North Arabian Gulf.

Baranof was replaced by the USCGC Clarence Sutphin Jr. (WPC 1147), which arrived at NSA Bahrain on Aug. 23, 2022. As part of the Coast Guard’s fast response cutter program, the service is acquiring 65 Sentinel-class fast response cutters, with six of those assigned to U.S. Coast Guard Patrol Forces Southwest Asia.

PATFORSWA, the Coast Guard’s largest unit outside of the United States, oversees the cutters in Bahrain. The ships are forward deployed to U.S. Fifth Fleet to help ensure maritime security and stability across the Middle East. The 154-foot long vessels feature advanced communications systems, and improved surveillance and reconnaissance equipment.

PATFORSWA, which is operationally attached to Fifth Fleet’s Commander Task Force 55, is composed of six FRCs, shoreside mission support personnel and a maritime engagement team. The unit plays a crucial role in maritime security, maritime infrastructure protection, and regional theater security cooperation. The unit also supports other U.S. Coast Guard deployable specialized forces operating throughout the Middle Eastern region.

“Iranian ship intercepted while trying to detain American drone” –Breaking Defense

Breaking Defense reports,

The US Navy’s 5th Fleet today announced it thwarted an attempt by an Iranian ship to seize an American unmanned surface vessel operating in the Arabian Gulf.

(See the video below.)

The unit that stopped this Iranian vessel from making off with the Saildrone was USS Thunderbolt (PC-12), supported by a helicopter of Helicopter Sea Combat Squadron 26, presumably an MH-60S. Vessels of this class are in the process of being decommissioned from the US Navy. Most of their functions will be performed USCG Webber class WPCs of Patrol Forces SW Asia.

This incident does seem to highlight a, not unexpected, aspect of Unmanned Surface Vessel (USV) deployment. Rogue nations and even non-state actors may try to steal them. As we see here, there may be little or no consequences if they are caught in the act, so there is little to deter a repeated attempt.

Next time it happens, it is likely that a Coast Guard cutter will be sent to retrieve it.

Wikipedia provides this information on the Saildrone Explorer.

“The Saildrone Explorer is a 23-foot-long (7.0 m) USV that can sail at an average speed of 3 knots (5.6 km/h; 3.5 mph) (depending on the wind) and stay at sea for up to 365 days. The Explorer is designed for fisheries missions, metocean data collection, ecosystem monitoring, and satellite calibration and validation missions.”

Bigger, more expensive and more capable Saildrones are on the way.

The US Coast Guard has been experimenting with Seadrones of this class, and has supported 5th Fleets experiments with them.

Story by NAVCENT Public Affairs   

U.S. Naval Forces Central Command / U.S. 5th Fleet

MANAMA, Bahrain – Two U.S. Coast Guard fast response cutters arrived in Bahrain, Aug. 23, marking the arrival to their ultimate destination after departing Key West, Florida in June.

USCGC John Scheuerman (WPC 1146) and USCGC Clarence Sutphin Jr. (WPC 1147) are two of the Coast Guard’s six newest Sentinel-class fast response cutters (FRC) now stationed in Bahrain where U.S. 5th Fleet is headquartered.

“This arrival represents the culmination of years of tireless effort and exceptional teamwork,” said Capt. Eric Helgen, commander of Patrol Forces Southwest Asia (PATFORSWA). “These newest FRCs bring us to our full complement of six ships and mark the beginning of a new era of extraordinary maritime capability supporting U.S. 5th Fleet.”

The Sentinel-class cutters in Bahrain are overseen by PATFORSWA, the Coast Guard’s largest unit outside of the United States. The ships are forward-deployed to U.S. 5th Fleet to help ensure maritime security and stability across the Middle East.

“We are extremely excited to be here and look forward continuing to work with international partners in the region,” said Lt. David Anderson, commanding officer of Clarence Sutphin Jr. “Completing this more than 10,000-nautical-mile transit to Bahrain has been a once-in-a-lifetime opportunity.”

John Scheuerman and Clarence Sutphin Jr. were commissioned in February and April 2022 respectively. The 154-foot long vessels feature advanced communications systems and improved surveillance and reconnaissance equipment.

Fincantiari of Italy Builds Two Small but Powerful OPVs

The Qatari Navy OPV is about 63 meters long, 9.2 meters wide, with a maximum speed of 30 knots. Giorgio Arra picture.

Naval News has done a couple of posts on a pair of Offshore Patrol Vessels (OPV) built in Italy for the Qatar Emiri Naval Forces by Fincantieri (owner of Marinette Marine in Wisconsin):

These are not your typical OPV. They look more like FAC(M) i.e fast attack craft, missile, but they trace their linage back through the UAE’s Falag 2 class to the Italian Coast Guard’s Diciotti class. Let’s compare to a typical OPV and talk about why they are so different.

First what is a typical OPV?

  • Displacement: at least 1,500 tons full load, typically less than 3,000
  • Length: at least 75 meters (246 ft), typically less than 100 meters (328 ft)
  • Range: at least 3500 nautical miles, typically 5,000 or more
  • Endurance: at least three weeks
  • Speed: 20-25 knots
  • Aviation: At least flight deck for medium helicopter
  • Boats:  at least two RHIB of 7 meters or larger
  • Weapons: one deck gun of 76mm or less plus two to four guns .50 cal to 30mm guns with one or two typically mounted in remote weapon stations. Anti-Ship Cruise missiles are rare and Anti-Aircraft missile systems more capable than MAPADS rarer still.

Examples include ships building or in service with Argentina, Australia, Britain, India, Japan, Malta, the Philippines, Singapore, Türkiye, the Fassmar designs used by Chile, Colombia, and German, and Damen designs used by Malaysia, the Netherlands, Pakistan, and Vietnam.

The 270 foot Bear class WMECs fit the profile pretty well, if you ignore the fact they can’t quite reach 20 knots. In some respects they are still more sophisticated that some of the newer OPVs.

The 210 foot Reliance class WMECs fall outside the current norm, being smaller and slower than typical, but they otherwise fit the profile. Of course even the newest is 53 years old.

Now let us compare the new Qatar OPV.

Range/Endurance:

Their range is only 1500 nautical miles at 15 knots, that is even less than that of the smaller Webber class cutters’ 2500 at 14 knots. Their seven day endurance is more typical of the smaller Inshore Patrol Vessel class. As a patrol vessel, it is closer to the Webber class WPCs than even the Reliance class.

Persian Gulf. US Government work product in the public domain.

Geography is the reason. Qatar’s coast line is only 563 km and its EEZ is 31,819 sq km (that of the US is 11,351,000 sq km, 357 times greater). They just don’t have to go very far. It may also be that these ships will be used more in reaction than as actual patrol vessels.

Size:

Full load displacement is 725 tonnes, with a length of 63.80 (209 feet) (59.60 meters or 195.5 feet between the perpendiculars) and a beam of 9.20 meters/30 feet. This makes them smaller than the Reliance class and only about half the size of the smallest of the typical OPVs. Rough seas are probably less of a concern than in more open areas.

Speed:

Their speed of 30 knots, rather than the typical 20 to 25, also seems to suggest their role is one of rapid reaction rather than persistant patrolling.

Aviation:

Unlike most modern OPVs, there is no apparent provision for supporting aviation assets, not even UAS. That is presumably because land based air is always close.

Boats:

The OPV has a stern area with crane for launch and recovery of a RHIB. This is not an arrangement that suggests the boat would be used frequently or that boat ops is a high priority.

The second Musherib-class OPV “Sheraouh” for the Qatar Emiri Naval Forces. Fincantieri picture.

Amaments:

“…in addition to the NA-30S Mk2 FCS for the Leonardo Super Rapido 76/62 mm Multi-Feeding main calibre gun, the Leonardo-provided  EO/IR suite also includes two SASS IRSTs and a single Medusa Mk4B FCS for the two 30 mm Marlin-WS secondary gun systems. The missile armament package also includes two four-cell VLSs for the MBDA VL MICA surface-to-air system in the bow area and two twin-launchers for the MBDA Exocet MM40 Block 3 anti-ship missiles in the stern area.”

The Persian Gulf is a rough neighborhood. Qatar faces Iran across the relatively narrow Gulf. Potentially hostile craft are always close. Shore based anti-ship cruise missiles are always within range. Iranian surface units are at most only hours away, aircraft and missiles only minutes.

The vertical launch MICA missile system and Super Rapid 76mm gun provide credible defense against aircraft and cruise missiles.

While normally I would not feel four Exocets would be enough to provide two salvos of adequate size, against the potential Iranian opposition, four are probably adequate for two engagements.

It is not surprising these ships are better armed than any US Coast Guard cutter, including the more than six times larger National Security Cutters. They may be the most heavily armed “OPVs” in the world.

“These Are The Riverine Patrol Boats Ukraine Is Getting From The U.S.” –The Drive

Members of RIVRON 2 patrol Haditha’s dam and surrounding waterways, denying their use by insurgents, which in turn provides security to local fisherman. Location: Haditha Dam FOB, Anbar Province Iraq. (United States Navy, MC2 Kirk Worley) The package includes two of these.

The Drive/The War Zone has the best expanation I have seen so far as to the 18 boats that are to be transferred to Ukraine as part of the latest aid package.

While the 35 and 34 foot boats have been identified as to type, the six 40 foot boat have not. The post speculates that these may be of a type exported under Foreign Military Sales in 2020. I think, it is not unlikely these may be the new Navy 40 foot force protection patrol boats. They are an improvement on the 34 foot Sea Ark boats. They can be armored. They have an electro-optic system on the mast. They would be particularly useful if they had the remote weapon system on the bow they were designed to carry.

Naval News brings us a bit more informaton about the Navy’s new 40 foot force protection patrol boat. Most significantly,

NAVSEA: A total of 56 [40-foot Patrol] boats have been awarded to Metal Shark Boats and as of 9 May 2022, 20 boats have been delivered to the U.S. Navy.

In 2017 we discussed the program here and revisited it in 2019 here. The last indicated boats were being delivered at a rate of one every four weeks, meaning Metal Shark will likely be building these boats through early 2025.

Metal Shark calls this model the “40 Defiant” although it is actually 44 foot. Their description is here.

The 85-foot Defiant-class Near Coastal Patrol Vessel (NCPV) is being acquired by NAVSEA for Foreign Military Sales. Metal Shark photo.

There is also a some discussion of the Metal Shark “85 Defiant” patrol boat that is being produced for Foreign Military Sales. This is an evolution of the same design that gave the US Coast Guard its 87 foot “Marine Protector” WPBs (it too is actually 87 foot loa). The Navy calls this class Near Coastal Patrol Vessels or NCPV. We discussed this class in 2017. We noted at the time that Metal Shark had been award a contract,

“…potentially worth upwards of $54 million, Metal Shark will build up to thirteen 85-foot Defiant-class welded aluminum cutters for the Dominican Republic, El Salvador, Honduras, Costa Rica, Guatemala, and other United States partner nations. Additionally, Metal Shark will supply electro-optical infrared sensors, diagnostic equipment, in-country reactivation, crew familiarization, and test support to NCPV operators.

Metal Shark’s website has a description of the vessel here.
