Australia has joined an exclusive club following the successful firing of a Tomahawk cruise missile by HMAS Brisbane, a major milestone for the future firepower of the Royal Australian Navy.

The successful test firing makes Australia one of only three nations alongside the United States and United Kingdom to acquire, and now fire, the Tomahawk cruise missiles. HMAS Brisbane, a Hobart class destroyer, has successfully fired a Tomahawk missile during a test and evaluation activity conducted off the west coast of the United States.

Deputy Prime Minister and Minister for Defence, Richard Marles celebrated this capability milestone, saying, “The successful test firing of the Tomahawk missile demonstrates the strength of our alliance and defence cooperation with the United States, in support of a peaceful, stable and prosperous region.”

With an extended range of up to 2,500km, the Tomahawk is a world-class capability, which allows maritime platforms to perform long-range precision strike against land targets. Acquiring this capability significantly enhances the ADF’s ability to deter against any potential threat and keep Australians safe.

“By enhancing our own Defence capabilities, and by working with partners, we change the calculus for any potential aggressor so that no state will ever conclude the benefits of conflict outweigh the risks,” the Deputy Prime Minister added.

This Tomahawk firing follows the firings of the Naval Strike Missile and Standard Missile 6 earlier this year and is a practical demonstration of the speed at which the Albanese Government is delivering on its commitment to enhance the lethality of Navy’s surface combatant fleet.

Minister for Defence Industry and Capability Delivery, Pat Conroy echoed the sentiments of the Deputy Prime Minister saying, “The Tomahawk is the jewel in the crown and a step change in our firepower, deterrence and ability to strike land-based targets at ranges never before available to the Royal Australian Navy.”

Australia will acquire more than 200 Tomahawk missiles, which will be deployed in its Hobart class destroyers and future Navy platforms including Virginia class submarines and, subject to feasibility studies, the Hunter class frigates.

Canadian Frigate Destroys Target in Joint U.S.-Navy Littoral Missile Shoot

NAVAL BASE SAN DIEGO, Calif. – The Canadian warship HMCS Regina (FFH-334) visited California last month for something of a sailor’s ideal day: Killing a target at sea.

The crew did just that, albeit on the second try.

The Halifax-class frigate fired a Harpoon Block II anti-ship missile at a surface target in the Navy’s Point Mugu Sea Range off the California coast Oct. 23 during a U.S. Navy Joint Littoral Targeting Exercise 2024, Canadian Armed Forces announced last month.

The initial strike, though, didn’t exactly go as planned. The missile lost communication with the intruments that measure the . “Without getting into too many of the technical details, there was an issue with the first missile,” the frigate’s commander, Cmdr. Jeremy Samson, told Canadian TV on Oct. 24. “When you fire a missile on a range, there are safety procedures to make sure the missile is doing what it’s supposed to, and losing that communication can cause you to order the missile to destruct.”

Sea range operators tracking the missile terminated its flight less than a minute after Regina launched the Harpoon, Royal Canadian Navy officials confirmed to USNI. A second Harpoon II missile launched and flew without issue and successfully struck the target, officials said.

“HMCS Regina’s crew were well prepared for this possibility. Live-fire naval exercises are partially conducted to test a warship’s adaptability to changing circumstances,” Commodore David Mazur, the Canadian Fleet Pacific commander, told USNI in an email response to questions about the missile exercise. “After the destruction of the first missile, HMCS Regina’s combat team rapidly launched a follow-on missile that successfully reached its target.”

“Safety is paramount during any military live-fire exercise, with communications with the missile and range facility verified before launch,” Mazur said. “If communication is lost – even temporarily, and for any reason – the range will terminate the missile in flight. In this case, the range lost tracking of the missile about 15 seconds after launch and immediately initiated the Command Destruct process.”

The scenario-driven exercise put the crew, along with embarked fleet staff, through the paces of coordinating with their joint U.S. counterparts through the processes from identifying threats and targets, developing targeting packages and doing the actual strike mission in the Navy’s instrumented sea range.

“These exercises allow Canada’s ships and sailors to advance important skills under immersive conditions,” Mazur noted.

The live-firing drill wasn’t just about killing the target. Rather, it focused on “tactical development” and training the crew and commanders on current threats at sea, officers said.

The ship’s RGM-84 Harpoon Block II missile “can fire surface-to-surface, but it can also do surface-to-shore. We’re testing out some capability and targeting processes for Canada and to respond to a situation that you might see like what’s going on in Ukraine right now,” Mazur said during an interview last month aboard the 440-foot patrol frigate at the San Diego 32nd Street naval station. “So we’re trying to push the envelope.”

In training with the U.S. Navy to hone the ship’s strike capability, Regina sailors and Mazur’s command staff worked through the intricate details, planning and processes at the tactical and operational level that a live-fire strike at sea requires.

“It’s the development of the intelligence pictures, the development of the situational awareness that gets you to the point where you can say, ‘I’m in danger and I need to shoot at something.’ We don’t practice that very often,” he said. Regina fired a Harpoon during a 2020 Rim of the Pacific sinking exercise.

The targeting enterprise, he added, was “the very first time we’ve done it in this depth, using our operational headquarters, going all the way up to our strategic headquarters.”

Regina operated on the Point Mugu range and responded to the threat with two other Canadian ships in the navy’s simulated live, virtual and constructive environment.

“So we’re doing it all up on our own,” Mazur said, “and that allows us to test our own chain of command without full integration and reliance on someone else’s.”

They deliberately operated closer to shore, rather than farther out to sea, Mazur explained.

“You can see how Ukraine is targeting things in the Black Sea. We have focused mainly on, I would say, the very tactical level. There’s a box ashore and the ship gets an order and fire[s] at the box ashore,” the commodore said. “We’ve done those kinds of shots and we fired at sea during [Rim of the Pacific exercises] and other things where the ship develops its own picture with an aircraft and shoots.”

It’s historically rare for an RCN frigate crew to fire live Harpoon missiles. HMCS Vancouver (FFH-331) did the previous run during the summer’s Rim of the Pacific exercise, Mazur said. “We’ve never really done the complexities of littoral and targeting” that involve the complex coalition environment with aircraft, artillery, forces ashore and friendly shipping in the mix, he said.

“We learn something new every time, particularly how to be more interoperable with more partners,” said Cmdr. Tyler Smith, a missile exercise planner.

The Esquimalt, British Columbia-based Regina had traveled to join in San Francisco Fleet Week activities and get equipment and communications installs for the missile exercise as the crew prepared intently for the live-fire exercise.

“We’ve been studying like crazy here,” Sub-Lt. Adam Beaupré, a junior officer aboard Regina, said a few days before the exercise. “It’ll be really awesome to see that go off.”

Regina’s crew averages 167 but nearly maxed out its berthing with 236 for the missile exercise. The crew routinely trains for missions involving humanitarian aid, disaster relief and search and rescue, said Chief Petty Officer First Class Timothy King, the senior enlisted sailor and equivalent to a command master chief.

“As we progress… we become warfighters,” King said.

Ahead of the rare live-fire missile drills, the crew focused on technical skills and the required missile readiness inspections, torpedo readiness inspections and weapons certifications.

“Harpoon, we don’t fire often,” King said. “We’re more of a support role and a first-line defense against submarines… That’s the bread and butter.”

Lt. Cmdr. George “Scott” Dyson, Regina executive officer, said the frigate is optimized for anti-submarine warfare.

“If you add us to an American task group, you get a ship that’s not so super awesome at shooting down aircraft,” Dyson said, “but we’re good at hunting and fighting submarines.”

King noted that Canadian patrol frigates routinely are invited to the Navy submarine commander’s course in Hawaii to give submarine commanders practice evading detection.

“We’re a more frustrating opponent. I mean, they still kill us all the time,” said Dyson. Los Angeles or Virginia-class U.S. submarines they encounter during training are “formidable opponents. They make us put the ship through the full envelope of its capabilities.”

While in San Francisco, Regina exchanged some crew with amphibious transport dock USS Somerset (LPD-25). The ships first met at sea while lining up with other vessels for Fleet Week’s parade of ships, an initial handshake between the bridge teams.

While trailing Somerset, “we were communicating back and forth, trying to get us off each other,” Beaupré said. “But now that I know exactly what’s going on in there, it’s just so much better. We know who’s going to talk to you, how that communication is going to go.”

Navy Boatswain’s Mate 1st Class Antonio Castro, who spent some time embarked aboard Regina, said both ship crews’ seamanship skills were equally matched, a benefit if they were to meet at sea or during an underway replenishment. Somerset sailors “would adapt very, very well” if they were aboard Regina, Castro said, and vice versa. “That’s important for our relationships.”

Sailors also spent time standing watch on the other ship’s bridge.

“Now when I’m working with a Canadian warship, I know exactly what’s going on in their heads, how they’re operating, what they’re thinking,” said Lt. jg Jacob Pratt. “I think that’s very important, especially because we’ve demonstrated such a close partnership that we are going to be working with each other continuously in the future.”

Partnerships and defense

The Royal Canadian Navy’s relationships with its U.S. ally and other partners are expected to strengthen across the Indo-Pacific with continuing deployments, a defense policy update that includes more military investments in force modernization and Arctic security.

Last month, the frigate HMCS Ottawa (FFH-341) deployed to support multinational sanctions against North Korea. “It’s going to be integrating with (USS) George Washington (CVN-73) and carrier battle group off Guam and the Japan area for a period of time,” Mazur said, noting that “more and more out-of-area deployers between Russia and China [are] going up towards the Arctic, doing research and training together.”

Regina and her crew are no stranger to China’s PLA Navy and its expanding influence across the Pacific.

In late July, while in the Bering Sea, the frigate encountered the Chinese research vessel Xue Long 2, one of three Chinese icebreakers routinely operating in the Arctic. Regina “was shadowing the Chinese,” Mazur said. Xue Long was reportedly part of a four-ship Chinese task force the U.S. Coast Guard cutter encountered, and it was tracked and monitored by the Royal Canadian Air Force CH-148 Cyclone helicopter embarked on Regina.

The recent Bering deployment – described in an official Facebook post as an “Arctic awareness and sovereignty mission” – was notable for another reason: In reaching the Bering Strait, Regina reached Latitude 69 degrees and became Canada’s “first West Coast frigate to cross the Arctic Circle.”

Such treks may become routine as China’s presence and Russia’s activity in the Arctic, Ukraine and in the Baltic Sea ramp up, said Mazur. “Everything’s slowly coming closer to North America, and we just have to … make sure there’s no seams between us, the U.S. Coast Guard, and [the] U.S. Navy.”

“You will see our ships continuing to deploy, at times integrating with the U.S. Navy, at times integrating with other friends and allies in the Indo-Pacific and achieving our own national objectives. You’ll see ships coming down here on a regular basis and going back up north,” he added.

The newest addition to the Pacific fleet is the HMCS Max Bernays (AOPV-432), its first Harry DeWolf-class offshore patrol vessel, and a second OPV, the Robert Hampton Gray, will deliver “in about 18 months,” Mazur said.

The six ships in the class will do maritime, sovereignty and surveillance operations in Canadian waters, including the Arctic, according to the RCN. They also “provide a little bit of deterrence… and demonstrate we have a capability up there,” Mazur said. “We’ll build that depth of knowledge going up north, working with the U.S. Coast Guard.”

The DeWolf class “brings us a capability of a ship that has extremely long range, which frigates do not necessarily have, so you’re always having to worry about resupply and fuel and all these things, whereas our Arctic patrol vessel can go extremely long range and not need resupply,” he said. “So they will give us a capacity to transit long distances throughout the Indo-Pacific.”

China tests carrier-like ship, but mystery vessel’s purpose remains murky

Images show ship with flight deck that can carry drones and helicopters, but it is not clear whether it is for civilian or military use

Hayley Wongin Beijing

Published: 7:00pm, 3 Dec 2024

China has tested a mysterious, carrier-like vessel featuring a large flight deck that is likely to be used for drones and crewed helicopters, according to photos and videos circulating on social media.

While the ship’s size and configurations are similar to the Chinese naval Type 075 landing helicopter dock, its light aircraft carrier design with three, instead of two, protruding island-like structures has made it a first of its kind.

The ship, measuring some 200 metres (656 feet) long, is believed to be docked at a facility owned by shipbuilding company Comec on Longxue Island in the southern city of Guangzhou. US military news site The War Zone, which was the first to report on the vessel, said it was probably a civilian research ship capable of supporting naval missions.

Comec, formerly Guangzhou Shipyard International Company, is a subsidiary under the China State Shipbuilding Corporation (CSSC) focused on commercial vessels.

According to The War Zone, the ship seems to have been launched between September 10 and October 9.

A video circulating on social media last week showed the vessel appeared to be sailing under its own power as little as two months after its launch, suggesting it was built very quickly.

The ship was spotted next to China’s large unmanned combat vessel JARI-USV-A, known as Orca, in October.

More photos circulating on American and Chinese platforms offered a closer look at the ship, showing two sets of markings on the vessel’s open flight deck. This type of flight deck is typically used for rotary-wing aircraft, either crewed or uncrewed.

But there were no clear signs – such as military-style markings or a hull number – that it was a military ship. There were also no signs of catapults or arrester cables that would be used for heavier fixed-wing aircraft, The War Zone reported on Tuesday.

The ship has a distinctive arrangement with three island-like structures along the starboard side of the flight deck. The multi-storey middle island appeared to be larger and taller than the other two.

“The superstructure nearest the bow includes a bridge and conventional-type mast, while the larger central one has a rear-facing glazed tower area for managing flight operations, plus a prominent mast, although the spherical radome seen on top in previously published images is missing here,” the report said.

“Finally, the structure closest to the stern houses the ship’s exhaust stacks.”

Open-source images collected by The War Zone suggest that the vessel has a simpler and cheaper design than military carriers or multifunctional amphibious assault ships and is more likely to be a private venture by CSSC than a project of the Chinese navy.

However, the line between China’s civilian and military vessels and technology is not always clear, and the facility where the ship is believed to be docked has hosted both civilian and military vessels, further muddying the picture of what the new ship will be used for.

The new vessel will add to China’s expanding range of domestically developed light and amphibious carrier vessels as the country builds up its maritime capabilities.

China has expanded its civilian research fleet and now has 64 vessels in use, according to a recent report by the Centre for Strategic and International Studies think tank.

US Navy fits first shipborne hypersonic missile system to stealth ship Zumwalt

3rd December 2024 at 8:35am

The US Navy is adding its first-ever shipborne hypersonic missile system to one of its stealthy guided missile destroyers.

The potent weapon is being retrofitted to USS Zumwalt, with the missile tubes replacing gun turrets that were never activated because they proved too expensive.

The work is underway at a shipyard in Mississippi, and once complete the warship will be capable of conducting fast, precision strikes from greater distances.

The latest development comes as the US continues its arms race with Russia and China to develop and implement new hypersonic weapon technologies.

Travelling beyond Mach 5, at five times the speed of sound, hypersonic weapons have added agility to their speed, making them far harder to shoot down.

This could see hypersonic missiles transforming the future battlefield.

All three of the Zumwalt-class destroyers are to be equipped with four missile tubes, with each one taking three missiles, giving a total of 12 hypersonic weapons per ship.

Bryan Clark, a defence analyst at the Hudson Institute, told the AP new agency that the initial inactivated gun turrets had been a “costly blunder”.

He said this was an opportunity for the US Navy to “take victory from the jaws of defeat here, and get some utility out of them by making them into a hypersonic platform”.

For the last two decades, the US has been developing several types of hypersonic weapons, but recent tests by both China and Russia have added pressure to begin rolling them out.

USS Abraham Lincoln Sails with Italian Carrier Cavour in Western Pacific

Dzirhan Mahadzir – August 9, 2024 3:44 PM

USS Abraham Lincoln (CVN-72) and Italian Navy carrier ITS Cavour (550) drilled together in the Philippine Sea according to an Italian Navy social media post on Friday. Meanwhile amphibious assault ship USS Boxer (LHD-4) arrived in Busan, South Korea on Friday.
The Italian Navy did not release a date as to when the two carriers sailed together but it is likely after the Abraham Lincoln CSG’s departure from Guam on Thursday.

Lincoln along with destroyers USS O’Kane (DDG-77), and USS Frank E. Petersen Jr. (DDG-121) departed Guam on while destroyer USS Spruance (DDG-111), also part of the Abraham Lincoln CSG departed Saipan the same day, after conducting a four day port call to the island, according to a Navy release.

Images released by the Italian Navy showed Lincoln sailing together with U.S. two destroyers, Cavour and frigate ITS Alpino (F594), while a combined flight group from the two carriers’ airwings flew overhead.

The Italian Navy stated that event was a “demonstration of interoperability between allies around the world and consolidation of the ability to integrate our forces wherever necessary.”

USNI News earlier reported that the Abraham Lincoln CSG would be deployed to the Middle East, relieving the Theodore Roosevelt CSG, though the timing of the handover has not been announced. The Abraham Lincoln CSG deployed without a cruiser, which will be more the norm in future as the Navy decommissions its cruiser fleet. USNI News understands Petersen is serving in the cruiser role. Three destroyers currently are part of the CSG though the number may increase if the Navy assigns additional destroyers already operating in the Asia-Pacific or in the Middle East to join the CSG.

The Cavour CSG is currently on a deployment to the Indo-Pacific, with an embarked air wing of F-35Bs Lightning IIs Joint Strike Fighters and AVB-8B Harrier IIs. The Cavour CSG recently took part in the Royal Australian Air Force’s multinational Pitch Black exercise that took place around Darwin, Australia from July 12 to Aug. 2 with its airwing augmented with an additional 8 F-35As and Bs flying into Australia as part of the Italian air group flying out from Italy to the exercise.

An Italian Navy release stated that the airwing of the Cavour CSG carried out 22 days of training totalling more than 180 hours of flight time and 110 missions including ground attack, in-flight refueling, take-offs and landings, air-to-air interactions, escort, Suppression of Enemy Air Defense (SEAD) and command and control.

The Cavour CSG’s deployment is part of meeting the Italian Navy’s target of Initial Operational Capability (IOC) of the F-35B in carrier operations. Capt. Dario Castelli, the carrier air wing commander said in the release that the IOC of the F-35B component will allow it to operate with allies, ensuring complete interoperability and interchangeability.

“Our participation in the Pitch Black 2024 exercise has allowed us to increase and strengthen the ability to project air and naval power from the sea,” said Castelli in the release.

The Cavour CSG is now headed to Japan to carry out drills before moving on to the Philippines, Singapore, India, Pakistan, Oman and Saudi Arabia before heading home to Taranto, Italy.

On Friday, amphibious assault ship Boxer pulled into Busan, South Korea for replenishment and crew rest, according to a report by South Korean media agency Yonhap, citing a Republic of Korea Navy statement. Boxer deployed on Jul.16 after completing rudder repairs that pushed back its planned April deployment to the Indo-Pacific. The big deck then operated around the 3rd Fleet while waiting for the 15th Marine Expeditionary Unit (MEU) elements that were to embark on it to wrap up their participation in the Rim of the Pacific (RIMPAC 2024) exercise with the 15th MEU embarking on the ship at sea on Jul. 23 according to DVIDS images.

In other developments, Japan’s Joint Staff Office issued reports on the activities on two PLAN destroyers and a Chinese UAV around its southwest island. In a Thursday release, the JSO stated that at 11 a.m. on Aug. 2, destroyers CNS Nanjing (155) and CNS Lishui (157) were sighted sailing south in an area 49 miles northwest of Uotsuri Island and subsequently sailed south in an area 43 miles west of Uotsuri Island and eventually sailed south in the waters between Yonaguni Island and Taiwan. The release added that on Wednesday, the two PLAN destroyers sailed southwest in the waters between Amami Oshima Island and Yokoate Island to enter the East China Sea. Japan Maritime Self-Defense Force (JMSDF) destroyer escort JS Oyodo (DE-231) a JMSDF P-1 Maritime Patrol Aircraft (MPA) of Fleet Air Wing 1 based at JMSDF Kanoya Air Base on the main island of Kyushu and a JMSDF P-3C Orion MPA of Fleet Air 5 based at Naha Air Base, Okinawa, shadowed the PLAN ships, according to the release.

On Friday, the JSO issued a release stating that in the morning and afternoon of that day, a Chinese BZK-005 military reconnaissance drone flew in from the East China Sea, then passed through between Okinawa and Miyako Island to reach the Philippine Sea, where it carried out a circuit flight then flew back the same way to return to the East China Sea. In response fighter aircraft of the Japan Air Self Defense Force (JASDF) Southwest Air District were scrambled, stated the release.

Jupiter Point: Joining Royal Navy sailors training at their ‘gateway to the sea’

Royal Navy sailors get first taste of life at sea at Jupiter Point

During their basic training at HMS Raleigh, Royal Navy recruits are given their first taste of life on the water – but it is not at sea. 

Well into their time at Torpoint, the recruits begin to experience the highs and lows of life on the waves on the River Lynher in Cornwall.

Kayaks, ribs and becoming swimmer of the watch drills are all a part of the experience, with Forces News joining the young sailors at Jupiter Point, the gateway to the sea for sailors, to find out more.  

Watch Video: AC-130J gunship pummels Navy vessel during Rim of the Pacific

A U.S. Air Force AC-130J gunship took part in battering and sinking a retired U.S. Navy vessel during this summer’s 2024 Rim of the Pacific exercise, according to explosive footage released by the Air Force.

A New Mexico-based 27th Special Operations Wing crew manning the AC-130J bludgeoned the Austin-class amphibious transport dock Dubuque with cannon fire from the air as part of a live-fire sinking exercise last month.

The former amphibious assault ship Tarawa was also sent to the ocean floor as part of the exercise. Footage of the Tarawa’s final moments above the ocean’s surface has yet to be released.

This year’s Rim of the Pacific Exercise, or RIMPAC, involved 29 nations, 40 surface ships, three submarines, 14 national land forces, more than 150 aircraft and 25,000 personnel. It is the largest international maritime exercise and allows militaries the opportunity to test high-powered weapons in real-world scenarios.

Over the roughly minute-and-a-half video, which was recorded off the coast of the Hawaiian island of Kauai, the AC-130J ambushes the Dubuque with a barrage of cannon fire.

Impacts can be seen across the vessel’s surface, with billows of smoke signaling each heavy strike.

Though not included in the video, Dubuque was also hit by U.S. Army AH-64 Apache helicopters and elements from the Japan Ground Self-Defense Force.

The Dubuque, which now rests 15,000 feet below the waves, was commissioned in 1967 and went on to serve in Vietnam before being decommissioned in 2011.

Ships sunk during the RIMPAC exercise must be cleaned of any toxic substances, such as mercury or petroleum, in compliance with Environmental Protection Agency regulations. Vessels must also sink at least 6,000 feet underwater and 50 nautical miles from land.

U.S. and Philippine Warships Patrol South China Sea

Aaron-Matthew Lariosa – August 1, 2024 7:21 PM

SOUTH CHINA SEA (July 31, 2024) – Independence-class littoral combat ship USS Mobile (LCS 26) conducts a Maritime Cooperative Activity with Philippine Navy’s Gregorio del Pilar-class patrol ship, BRP Ramon Alcaraz (PS 16), in the South China Sea, July 31, 2024. Mobile, part of Destroyer Squadron 7, is on a rotational deployment operating in the U.S. 7th Fleet area of operations to enhance interoperability with allies and partners and serve as a ready-response force in support of a free and open Indo-Pacific region.

U.S. and Philippine warships rendezvoused near a disputed South China Sea feature to conduct a joint maritime patrol on Wednesday.

USS Mobile (LCS-26) and BRP Ramon Alcaraz (PS-16) met off Leslie Bank, a maritime feature within Manila’s exclusive economic zone and Beijing’s 10-dash line claim. The littoral combat ship and ex-Coast Guard Hamilton-class cutter drilled in bilateral surface operations and communication, with a video released by the Armed Forces of the Philippines claiming that the two vessels took up a patrol formation.

According to the Navy, the joint patrol was meant to “demonstrate the strength of the alliance between the two nations and further advances combined capabilities in the maritime domain which support peace and stability in the Indo-Pacific.”

“Sailing together demonstrates commitment to our continued coordination with the Philippine Navy,” Capt. Justin Harts, commander of Destroyer Squadron 15, said in a press release on the maritime cooperative activity.

This activity is the latest in a series of maritime cooperative activities that began last year amid increasing tensions between the Philippines and China over their claims in the South China Sea, particularly over resupply missions to a Marine outpost at Second Thomas Shoal.

Joint patrols were envisioned in 2022 and 2023 to bring foreign partners into the South China Sea and Luzon Strait as a show of support. Philippine warships and aircraft have taken part in 10 bilateral and multilateral maritime and aerial patrols with countries including Canada, Australia, Japan and the U.S. since November 2023.

France has also been eyed as a participant pending the completion of an agreement between the two countries that would permit enhanced defense cooperation.

Despite the beginning of joint patrols last fall, incidents between Philippine and Chinese forces continued to escalate. The China Coast Guard’s use of water cannons, rammings and boarding actions eventually came to a head on a June 17 resupply mission when Canadian, Japanese, Philippine and U.S. jointly patrolled in the South China Sea.

This is the first time the Armed Forces of the Philippines has identified the relative location of a joint patrol, with a press release on the exercise saying the two vessels met at Leslie Bank, located 100 miles from the province of Palawan. While the feature is claimed by China as Yonghi Tan and Vietnam as Bãi Vĩnh Tuy, compared to other hotspots throughout the region, there is almost no active contest over the feature.

Following the exercise, Ramon Alcaraz resumed patrol duties and found a sunken Vietnamese fishing vessel at Jackson Atoll. It was later confirmed that the crew was rescued by another boat.

Four days before the maritime cooperative activity, the Philippines successfully resupplied its outpost at Second Thomas Shoal, BRP Sierra Madre (LT-57), following a yet-to-be-released agreement with China over the resupply of the grounded Second World War-era landing tank ship. Despite Manila and Beijing publicly disagreeing on the specifics of the deal, Secretary of State Anthony Blinken lauded the bilateral effort and urged China to uphold its end of the deal.

The joint patrol also occurred during Secretary of Defense Lloyd Austin’s visit to the Philippines, where he met with other high-ranking officials to finalize plans for further defense cooperation and modernization efforts under a half-billion-dollar investment from Washington into the Armed Forces of the Philippines. Austin also visited Subic Bay to examine potential defense industrial base opportunities at the former U.S. naval installation.
