The Royal Navy has spent the past 14 weeks gearing up a mine countermeasures response to send to the Persian Gulf region.
That mission will be the 16,000-ton civilian-manned Bay-class auxiliary RFA Lyme Bay (L3007), loaded up with lots of sorta ad-hoc bits and pieces, including the Video Ray Defender-Viper system, “four specialist mine-hunting vessels, three RHIBS, more than 20 containers packed full of tech,” and a skosh of good wishes.
20 May 2026 – HMS Stirling Castle is using their crane to load kit and equipment onto RFA Lyme Bay. RFA Lyme Bay receives a kit while in Gibraltar ahead of deployment to the Gulf. HMS Stirling Castle has transported and delivered kit, including drones and sea boats. The Bay-Class auxiliary ship is in Gibraltar, undergoing maintenance and loading vital kit for further operations.
A closer look at Video Ray
It really didn’t use to be this way.
Just 30 years ago, the circa 1996 RN, a victor of the Cold War, had five brand new 465-ton Sandown class Single Role Minehunters on hand with up to 20 planned as well as 13 aging (built in the late-1970s-mid-1980s) but still very useful 725-ton Hunt class minehunters.
There was also a backup.
At the time, four 700-ton River class sweepers, constructed in the mid-1980s, were being re-rated to patrol boats for the Northern Island Squadron. Eight additional Rivers were in reserve at Plymouth, with an eye towards disposal, even though they were not even a decade old. Speaking of reserve, 10 old Ton-class sweepers (including the experimental GRP-hulled HMS Wilton, M1116) were still “on the books” pending disposal and being used for training and Sea Cadet units, along with other roles.
No matter how you dice it, that’s more than a dozen very modern active boats, another dozen on the schedule, and a dozen more in reserve.

Since then, of the 15 Sandowns eventually completed (down from the planned 20), all save for HMS Bangor have been passed on to overseas allies, and Bangor was only given a last-minute reprieve to keep her around for five years.
Similarly, while seven of the now very old 13 Hunts are still on the RN’s list, just four (Ledbury, Cattistock, Brocklesby, and Hurworth) of those are manned and in service; the others are either laid up or transferred aboard.
The Tons and Rivers are long gone, save for Wilton, which is a floating museum.
The British Hunt class minesweeper HMS Cattistock (M31) celebrated her 40th birthday in 2022 and is scheduled to remain in service until age 50.
Spanish-American War, 1898. The prize crew going to take possession of the Spanish Colon after she was run aground after the Battle of Santiago, Cuba, July 1898. From Journal of Naval Cadet C.R. Miller, USN. 1898. Description: NH 2201
As the war in the Hormuz and the resulting blockade stretch into their 10th and fifth weeks respectively, and following up to yesterday’s Warship Wednesday on the blockade-enforcing lighthouse tender Mangrove, here is a closer look at the prizes from the Spanish-American War.
The first Spanish ships, the steamers Buena Ventura and Pedro, were captured on 22 April 1898 by the battleship USS New York and her accompanying escorts, with the gunboat Nashville claiming the prior.
The USS Nashville (Gunboat No. 7) fired the first shots of the war across the bow of the Spanish steamer Buena Ventura, outbound with a cargo of Mississippi pine lumber from Pascagoula to Rotterdam, to bring her to a stop on 22 April 1898, nine miles from Sand Key Light.
The capture took place just before the formal declaration of war, while the U.S. was establishing a blockade of Cuba, and the seizure was later upheld by the Supreme Court, 175 U.S. 384 (1899). Her cargo was released, as it was headed to the Netherlands, while Buena Ventura was sold at auction for $12,200, with a portion of that divided by the crew of Nashville and her squadron.
On the 23rd, the schooners Matilda and Condita were impounded. The 24th brought the steamer Miguel Jover and the schooners Sofia and Catalina.
This snowballed to 18 ships by the end of April, another 14 collected in May, just four in June, 19 in July, and one in August, with a total of at least 56 large commercial vessels impounded and sent to the court for adjudication.
All but four impounded vessels were “condemned with cargo” by the courts and sold, with 10 owners pushing the outcome to the Supreme Court.
The outliers that escaped sale included the British steamer Restormel Barry, which was released after her cargo was impounded. The British sloop Pilgrim was ordered released with cargo intact, as was the Mexican steamer Tabasqueno. The Spanish tug Humberto Rodriguez, seized off Nuevitas just two weeks before the end of the war by the auxiliary cruiser USS Badger, was ordered released by a New York Court as the tug carried red cross markings.
Some $701,034.36 was realized after auctions, deposited into the U.S. Treasury– with portions of said prizes paid to the crews of the vessels that captured them, an American tradition going back to 1798 and carried over from the British.
From the government records:
The above doesn’t include small coastwise vessels, of which an untold armada was collected, and were sold locally without being towed back to the U.S.
A prime example given is the auxiliary cruiser USS Dixie,which alone captured 89 lighters and sailing vessels at Ponce, considered a “good haul.”
Carrying 10 6-inch guns, the auxiliary cruiser USS Dixie, under CDR Charles H. Davis, had a very good war in 1898, entered the harbor at Ponce, Puerto Rico, on July 27, forcing the town to surrender and securing a landing place for the U.S. Army forces, claiming 89 of 91 small vessels in the harbor for her trouble. Post-war, she became the Navy’s first destroyer tender, AD-1, and continued to serve until 1922.
It should also be noted that this is above and beyond claims for Bounty filed by U.S. warships for destroyed and/or captured Spanish naval vessels, with the monies distributed to the crews, with squadron commanders included at a larger share.
For reference, Dewey was awarded $28,070 in bounty and prize money for the Battle of Manila Bay (his “cut” of $244,400) while Sampson pocketed a more paltry $8,335 (out of $166,700) for the destruction of the Spanish squadron off Santiago. Keep in mind that the base rate for rear admirals of the era was $4,675 per annum.
All awards of prize money and bounty money to U.S. Navy personnel were abolished by Congress via the Act of March 3, 1899 (30 Stat. 1121), with later much-hyped instances, such as the capture of the German cargo ship Odenwald in 1941 by the USS Omaha and Somers, being paid under salvage rights granted under maritime law, not as “head” money.
With that foundation under us, it has become super interesting that the Navy has delivered its first disabling gunfire against a large surface vessel since 1988, with several 5″/62 rounds delivered into the engine room of the M/V Touska by the USS Spruance (DDG 111) while operating as part of the Abraham Lincoln Carrier Strike Group.
It was certainly the old “cruiser rules” with Sprunace firing five warning shots and opting to use nine BLP (Blind Loaded Projectile, the blue, steel projectile loaded with inert contents) to wreck Touska’s engine room after several broadcasted warnings and a six-hour pursuit.
Dead in the water, Touska was soon boarded in a night operation by Marines from the 31st MEU carried via helicopter from USS Tripoli (LHA 7). Some real deal VBSS stuff on a 73,000-ton/968-foot Panamax-sized container ship– not your more typical seizure of an unflagged dhow that the Navy has typically done in the past several decades.
Such an incident shows the value of a 5-inch gun aboard a grey hull for just such a moment– and underlines why the Navy’s next frigates (and the Coast Guard’s larger cutters) need such a weapon installed. Bofors 57s aren’t going to get it.
Either way, you know Spruance’s already colorful forward mount will receive some extra paint on its gun house.

Then came the interception of the Iranian-chartered “Botswanan-flagged” (officially stateless) crude carrier M/T Tifani— 156,967 gross tons of shipping– on the 21st in the Bay of Bengal.
Of interest, she was seized by a converted tanker design, with an Expeditionary Sea Base, possibly the Lewis B. Puller-class USS Miguel Keith (ESB 5), seen just off her bow in the photos released by CENTCOM and DoW.
There is no way you can look at that as other than a direct call back to the auxiliary cruisers of the Russo-Japanese War, WWI, and WWII, which typically saw gently converted mail steamers and ocean liners modified with a few guns, some paint, and a military crew, then sent out to halt enemy blockade runners and similar auxiliary cruisers flying the flags of the other guys.
On 22 April, CENTCOM said that it had intercepted a total of 29 ships as part of the now nine-day-old blockade, including five Iranian-flagged/contracted/controlled tankers (Diona, Sevin, Dorena, Derya, and Deep Sea).
To wit, the IRCG has also said they have bagged a couple of ships of their own.
Official caption: “An F-35B stealth fighter jet is prepared for flight aboard USS Tripoli (LHA 7) as the amphibious assault ship sails in the Arabian Sea. Tripoli and its 3,500 Sailors and embarked Marines are executing the mission to blockade ships entering and departing Iranian ports. The blockade is being enforced impartially against vessels of all nations.”
The “Green Knights” of Iwakuni-based Marine All Weather Fighter Attack Squadron (VMFA) 121 trace their lineage back to 1941 and were charter members of the Cactus Air Force during the Guadalcanal campaign, then went on to produce 14 aces– more than any other Marine squadron during WWII– downing 208 Japanese aircraft in the process.
They went on to fight in Korea (flying Skyraiders), Vietnam (Skyhawks then Intruders), became the first Marine F-18D night attack squadron in 1989 once the A-6 was retired, logged over 2,000 combat sorties during GWOT, and have been riding the Lightning since 2012.
Their motto is “Have Gun Will Travel,” which tracks.
Not going to get into it in too much detail, as I am sure you guys are getting a firehose of this information right now on Epic Fury, or as I like to call it — Praying Mantis II — but I did see this interesting and important footnote to military history.
Saturday’s attack was the Pentagon’s first use of one-way (i.e., “kamikaze”) drones in combat, with CENTCOM’s Task Force Scorpion Strike admittedly using SpektreWorks FLM-136Low-cost Uncrewed Combat Attack System one-way attack UAVs as part of a sweeping 4,000 items-of-ordnance blitz.
Of some hilarity, the $35K (or less) LUCAS is an unlicensed reverse-engineered knock-off of the Iranian HESA Shahed 136, which has given the Navy so much heartburn in the Bab el Mandeb in the past couple of years and has been extensively captured in Ukraine.
And that is a bit of delicious irony.

One of the first publicized launches of the 10-foot LUCAS was via RATO from USS Santa Barbara (LCS 32) while operating in the Arabian Gulf last December. She is one of three Independence-class ships, including USS Canberra (LCS 30) and USS Tulsa (LCS 16), that are currently forward-deployed to Bahrain with new MCM mission modules, replacing the legacy Avenger-class ships that have served in Task Force 55 for over 30 years

So it may be doubly interesting to see just from where those LUCAS UAVs were launched.
The four recently decommissioned 224-foot U.S. Navy Avenger-class Mine Countermeasures ships — the former USS Devastator, USS Dextrous, USS Gladiator, and USS Sentry — have departed Bahrain aboard the 65,000-ton Norwegian-flagged merchant heavy-lift vessel Seaway Hawk, marking their final voyage through the Arabian Gulf.
Seaway Hawk was escorted by USS Canberra (LCS 30), one of the three-pack of newly MCM-optimized Independence-class ships– the others being USS Santa Barbara (LCS 32) and Tulsa (LCS 16)-– that are currently forward-deployed to Bahrain, replacing the legacy Avenger-class ships that have served in Task Force 55 for over 30 years.
This isn’t the first time 5th Fleet MCM has passed the torch in the region with generational changes. Several circa-1950s wooden-hulled 120-foot Aggressive-class ocean minesweepers, including the USS Adroit (MSO-509) —subject of an upcoming Warship Wednesday —the USS Impervious (MSO-449), and the Leader (MSO-490), were deployed to the Persian Gulf beginning in 1990, notably supporting Operations Earnest Will, Desert Shield, and Desert Storm.
Before that, the old ‘phib USS Okinawa (LPH-3) had operated Navy RH-53D Sea Stallion minesweeping helicopters in the Gulf during Operation Ernest Will, and six small minesweeping boats (4 x 57-foot MSBs and 2x 36-foot MSLs) of Mine Group Two, Mine Division 125, had arrived in the region on USS St. Louis (LKA-116) and USS Raleigh (LPD-1) in the summer of 1987.

These brownwater boats were later augmented by the Aggressive class bluewater boats USS Fearless (MSO-442), Inflict (MSO-456), and Illusive (MSO-448), towed by USS Grapple (ARS-53) to the region. The epic nearly 10,000-mile journey began on 6 September 1987 and lasted roughly eight weeks, arriving in the Gulf of Oman on 2 November 1987. Upon arrival, the Inflict discovered and destroyed the first underwater contact mines in the northern Persian Gulf countered by an American minesweeper since the Korean War.

230913-N-N3764-1004 NAVAL STATION KEY WEST, Fl. – (Sept. 13, 2023) — Commercial operators deploy Saildrone Voyager Unmanned Surface Vessels (USVs) out to sea in the initial steps of U.S. 4th Fleet’s Operation Windward Stack during a launch from Naval Air Station Key West’s Mole Pier and Truman Harbor, Sept. 13, 2023. Operation Windward Stack is part of 4th Fleet’s unmanned integration campaign, which provides the Navy a region to experiment with and operate unmanned systems in a permissive environment, develop Tactics, Techniques, and Procedures (TTPs) against near-peer competitors, and refine manned and unmanned Command and Control (C2) infrastructure, all designed to move the Navy to the hybrid fleet. (U.S. Navy photo by Danette Baso Silvers/Released)
U.S. Naval Forces Southern Command/U.S. 4th Fleet doesn’t have a lot of afloat assets.
Typically, they just get to task Coast Guard cutters/craft via the Key West-based Joint Interagency Task Force South, Freedom-variant littoral combat ships out of Mayport’s LCSRON2, small MSC-operated auxiliaries on hearts-and-minds missions, and the occasional passing phib group being sent down for an exercise or destroyer pulling an interdiction mission with an embarked USCG LEDET.
That’s what makes USVs such a game changer for the command.
They are cheap to acquire and deploy, ideal for ISR– making other assets much more effective– and have a small footprint.
Plus, using them in our “front yard” allows the Navy to iron out tactics and techniques in permissive environments before they are needed in higher-stakes operations in, say, the South China Sea or the Persian Gulf.
Operation Southern Spear, which is filling my local skies with F-35s and HH-60s of all sorts, will see more Robotic and Autonomous Systems (RAS) assets incorporated.
Specifically, Operation Southern Spear will deploy long-dwell robotic surface vessels, small robotic interceptor boats, and vertical take-off and landing robotic air vessels to the USSOUTHCOM AOR. 4th Fleet will operationalize these unmanned systems through integration with U.S. Coast Guard cutters at sea and operations centers at 4th Fleet and Joint Interagency Task Force South. Southern Spear’s results will help determine combinations of unmanned vehicles and manned forces needed to provide coordinated maritime domain awareness and conduct counternarcotics operations.
Ten 33-foot Saildrone Voyager USVs are used by the 4th Fleet and the company says that figure is set to rise to 20 such drones, tasked in support of Operation Southern Spear “to detect and stem the flow of illegal drugs traveling through known maritime corridors into the United States.”
The 33-foot Saildrone Voyager is designed for near-shore bathymetry and maritime security missions.
10 Voyager uncrewed surface vehicles (USVs) from Naval Air Station (NAS) Key West’s Mole Pier, Sept. 2023.
In recent 2023-24 operations (Windward Stack), Saildrone disclosed that the 10 4th Fleet Voyagers sailed more than 130,000 nautical miles over 2,700 cumulative mission days. They detected 116,000 unique contacts, an average of 43 contacts per USV per day. Of the total contacts, 98,000 were not broadcasting AIS. Saildrones covered an area of 12,500 sq nm for $4.25 per nm per day, as calculated by the Center for Naval Analysis. This included shadowing three Russian ships as they approached Cuba in 2024.
Those figures should roughly double now with 20 Voyagers on hand.
A record number of 20 high-endurance Saildrone Voyager USVs equipped with a newly upgraded sensor suite will monitor illegal activity along the United States’ southern maritime approaches, operating in support of Joint Interagency Task Force South (JIATF-S) and US Naval Forces Southern Command/US Navy Fourth Fleet (NAVSOUTH/FOURTHFLT).
“It’s an honor to support the US Navy and Joint Interagency Task Force South in this critical border security mission,” said Richard Jenkins, Saildrone Founder and CEO. “As we increase the security on our southern land border, criminal activity will naturally get pushed to our maritime borders. Saildrone is proud to serve, providing a persistent, unblinking eye in maritime areas too vast and remote to previously monitor.”
A vintage deck gun system that was once a staple of the U.S. Navy and Coast Guard has quietly fired its final shots.
Designed by the famed munitions firm of OTO Melara of La Spezia, Italy, and marketed from 1963 onward as the 76/62C Compact, the remote-controlled 76mm (3-inch) gun with its characteristic bubble dome was an immediate hit with NATO and Western fleets, eventually seeing service with 60 nations.
West German Type 148 missile boats show their 76mm OTO guns during a visit to the UK, in 1977
The reason it was so popular was that using aluminum alloys, a water-cooled gun barrel, and an automatic loader with an 80-round magazine, it delivered much better performance than any manned 3-inch gun mount in service at the time while weighing much less. Guided by the ship’s onboard radar and fire control system, it could engage air targets as high as 13,000 feet and surface targets out to 20,000 yards.
The 76/62 designation comes from the bore (76mm) and barrel length (62 caliber), the latter figure denoting a 4,724mm long barrel, which translates to 15.5 feet.
The 76/62C Compact, seen in its components from a 1980 U.S. Navy training publication:
Note the gun control panel which was mounted in the ammunition handling room below deck under the mount. The mount captain fired the gun from the panel while two ammunition loaders stood by to reload the magazine.
A look under the hood so to speak, showing off the details of the gun itself and its magazine.
The mag used two concentric rings of shells, each holding 35 rounds, with a hydraulic motor rotating the screw feeder– which held another six rounds not unlike that of a common “six-shooter” revolver. Together with the four rounds held in the loader drum, the gun held 80 shells, which could be expended in just under one minute.

The types of “war shot” rounds in U.S. service included High Explosive Point Detonating (HE-PD), High Explosive Infrared (HE-IR), Variable Time Non-fragmenting (VT-NF), High Explosive Variable Time (HE-VT), and High Explosive Radio Frequency proximity (HE-RF).
Exercise and training shells included the Blind-Loaded and Plugged (BL&P) round with a live round that had an inert projectile while wholly inert rammable and non-rammable dummy and gauging rounds were also available.

For a great look at the inner guts of the 76/62C Compact, check out this short video from the German Navy, which has used the gun since 1965. Don’t worry if your German is rusty, the video speaks for itself.
With the U.S. Navy opting to mount a smaller 3-inch gun on its planned Oliver Hazard Perry-class frigates in the 1970s– a big change from the manned 5-inch guns mounted on the Knox-class frigates that preceded them– the Pentagon went with the Italian “robot gun” design.
A destroyer escort, USS Talbot (DEG-4), in late 1974 had an Italian-produced 76/62C Compact installed on her bow forward of the superstructure in place of the ship’s original 5-inch manned mount which used a design that dated to World War II.

The Naval Systems Division of the FMC Corporation in 1975 won the U.S. contract to build the 76/62C Compact in Pennsylvania under license from OTO Melara and delivered the first American-built model in August 1978. The Navy, which designated the gun the MK 75, went on to install them in 51 Oliver Hazard Perry-class frigates built between 1975 and 1989, along with six Pegasus-class hydrofoil fast attack craft and on the Coast Guard’s 13 new Bear-class cutters that were constructed in the same era.
Likewise, when the Coast Guard’s 12 Vietnam-era Hamilton-class cutters were modernized starting in 1987, they received the MK 75 to replace their outdated 5-inch mounts. The guns were also installed on a series of warships built in the U.S. for overseas customers (Israel, Egypt, Australia, et.al).
The frigates carried the MK 75 atop their superstructure as the bow, the traditional location, was occupied by a missile launcher and its below-deck magazine.

One of the frigates, USS Simpson (FFG-56), part of Surface Action Group Charlie, had the first combat use of the MK 75 in U.S. service when, in April 1988, used the gun to destroy Iranian naval and intelligence facilities on the Sirri oil platform during Operation Praying Mantis.
Another frigate, USS Nicholas (FFG-47)used her MK 75 during Desert Storm in January 1991 to clear Iraqi troops placed on nine oil platforms in the northern Persian Gulf off of occupied Kuwait. As reported at the time, the frigate “fired three shots at each platform to set the range, followed by about 20 rounds of high-explosive shells, ‘for effect.’ The effect was to demolish quickly all the remaining bunkers.”
The speedy hydrofoils, meanwhile, wore their MK 75 as a hood ornament.
As did the Coast Guard cutters.

The water-cooled barrel, using salt water during the firing process and a freshwater flush from the ship’s onboard supply after the firing ceased, led to often extreme muzzle shots with the intersection of steam and propellant.

All things come to an end
However, there has been a slow-motion end to this story that started with the retirement of the hydrofoils in 1993, and the frigates losing their MK 75s by 2015 in a series of refits. This left the Navy, who “owns” the installed weapons on Coast Guard cutters, still on the hook for logistics contracts with BAE systems and OTO Melara (now Leonardo) for parts and support.
Those days are gone as the 76/62C is out of production both in the U.S. and Italy, with Leonardo replacing the system in its catalog with the faster-firing (though still with only an 80-round ready magazine) and more stealthy 76/62 Super Rapid (SR) Gun Mount.
Eventually, the Ordnance Shop at the Coast Guard yard took ownership of the MK 75 program and was even tapped to support the guns on frigates and cutters transferred overseas.
Since then, the Hamilton class has all retired and has been transferred overseas and now the Bear class cutters are in the process of being stripped of their MK 75s during refits, and replaced by smaller (albeit currently produced) MK 38 25mm guns. Overseas allies are similarly phasing out the gun.
This brings us to the coda of the Bear-class USCGC Mohawk (WMEC 913) firing her MK 75 for the last time this summer, an event that was held during a gunnery exercise in the Florida Straits. The service said in a press release this week that it was a “significant historical event” as Mohawk was “the last in its class to fire the onboard Mk 75 gun weapon system.”

Perhaps once the mount is phased out for good, the USS Aries Museum, the only preserved U.S. Navy hydrofoil, can pick up one of the old MK 75s to help complete her Cold War profile.
There is much more color that has been added to the tragic 11 January boarding, search, and seizure of the stateless dhow of the Somali coast, reportedly packed with Iranian rocket and missile components headed for the Houthi. The boarding resulted in the deaths at sea of two SEALs, Special Warfare Operator 1st Class Christopher J. Chambers, 37, and Special Warfare Operator 2nd Class Nathan Gage Ingram, 27.
Chambers and Ingram were declared lost at sea on 22 January after being missing for 11 days
The information comes from an odd source, the DOJ, which indicted four foreign nationals this week who were members of the crew of the dhow– Muhammad Pahlawan, Mohammad Mazhar, Ghufran Ullah, and Izhar Muhammad– who made their initial appearance via teleconference before a U.S. Magistrate Judge in Richmond, Virginia. Ten other crewmembers are being held as material witnesses but are not charged.
The boarding was accomplished by members of a West Coast-based Navy SEAL team and USCG MSST elements operating from the 100,000-ton sea base, USS Lewis B. Puller, supported by helicopters and unmanned aerial vehicles. Once the VBSS team was aboard (sadly, after losing Chambers and Ingram in the process) they confirmed it was a stateless vessel and proceeded with the search. Although the crew at first said that they had been fishing for the past six days, there were no fish aboard and no fishing equipment in use. The crew said they were unaware of any cargo on the dhow.
What the VBSS team turned up were a series of warhead, and propulsion and guidance components for MRBMs and anti-ship cruise missiles, all “packaged without markings, labels, or identification in compartments near the front of the dhow.”
“The military’s belief that the weapons are Iranian is based in part on labels on various components, the recovery of similar exploded or destroyed missiles and destructive devices from other Houthi attacks in the region around the time of the seizure, and comparison of seized weapons to known information about Iranian manufactured missiles and rockets.”
The rocket and missile parts were found hidden in culvert piping and net float buoys and the 14-member crew transferred to the Puller, which then became a floating brig. The dhow was sunk by the Navy afterward as it was deemed “no longer safe or seaworthy.”
Several of the crew had Pakistani identification cards and in interviews, some said the dhow came from Pakistan and they didn’t know what the cargo was, while others said it came directly from Iran. One, Pahlawan, who told the rest of the crew to only refer to him as a refrigeration mechanic, was in charge. Pahlawan said he had been in Iran for two years and that he began working on the dhow 10-15 days before it left Konarak, Iran, where it had been inspected by the Iranian Navy an hour before it departed. Once they left Konarak, they took on diesel at night at Chah Bahar, a known base of the Islamic Republic of Iran Navy.
Pahlawan said he was instructed by the owner and captain of the vessel– neither of which embarked– on what heading to take toward the Somali coast and was given a sat phone to communicate with an individual through a series of calls that the FBI traced back to an individual known to be affiliated with the IRGC.
Of note, Pahlawan also had a personal cell phone and was active on Facebook, Snapchat, Instagram, and TikTok. You gotta stay on top of things, after all.
As noted by the DOJ:
Pahlawan faces a maximum penalty of 20 years in prison if convicted of unlawfully transporting a warhead, and all four defendants face a maximum penalty of five years in prison if convicted of the false statements offense. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
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.
Douglas Denman arrives in Alaska after a 7,000-mile cruise
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.
