US Air Force to Arm C-17 Globemaster with Hypersonic Missiles: Boeing Unveils New 'Revolver' Launch System

 The US Air Force's second-largest airlifter, the C-17 Globemaster III, is set to gain significant offensive capabilities. Boeing has introduced the "Revolver" launch system, which will enable the aircraft to launch multiple hypersonic missiles from its cargo bay. This adaptation aligns with the USAF's strategy to enhance the offensive capabilities of airlifters like the C-17 and C-130J, particularly in the Indo-Pacific region where conflicts with China may arise.

The USAF's plan anticipates that cargo and tanker planes will need to provide more than logistical support in potential confrontations with powerful adversaries like Russia or China. The Revolver system is designed to integrate X-51A Waverider hypersonic cruise missiles, allowing the launch of 12 missiles using an advanced drum and electromagnetic catapult mechanism. These missiles, known for their scramjet engines, can exceed Mach 5, offering long-range precision strikes.

Originally intended for the B-52 Stratofortress, the X-51 program involved collaboration among the Air Force, DARPA, NASA, Boeing, and Pratt & Whitney Rocketdyne. Although the X-51 was scheduled for mid-2020s service, delays have pushed back its deployment.

In 2013, the X-51A achieved a historic hypersonic flight, maintaining scramjet power for three and a half minutes at Mach 5.1. Boeing showcased the Revolver concept in a video, emphasizing its versatility and enhanced capabilities for the C-17.

The C-17, capable of transporting 102 paratroopers, 54 patients, or 85 tons of cargo, is a critical asset for global operations. With the Revolver launcher, it will also serve in missile deployment, enhancing its role in modern military logistics.

Boeing's efforts in hypersonic technology also include the DARPA Glide Breaker program, aiming to develop a hypersonic interceptor prototype. Meanwhile, China's advancements in hypersonic weaponry pose a significant challenge, with the US making substantial investments to close the gap, including a $756 million contract with Lockheed Martin for ground-based hypersonic systems.

The USAF tested a hypersonic cruise missile in the Pacific in March, demonstrating its commitment to remaining competitive. Recent exercises with the C-17 have involved loading and unloading missile cradles, illustrating its flexibility to operate from various airfields.

The Rapid Dragon project explores deploying cruise missiles from cargo planes, allowing C-17s to carry out offensive missions with minimal modifications. This approach is seen as cost-effective, providing strategic advantages by leveraging existing transport fleets.

China is wary of this capability, recognizing the difficulty in tracking cargo planes capable of launching missiles from unexpected locations. Overall, the C-17's transformation into a missile-carrying aircraft exemplifies the evolving strategies in modern warfare, with significant implications for global military dynamics.

Japan Unveils Future Destroyer with Game-Changing Electromagnetic Railgun Technology

 In October 2023, Japan achieved a significant milestone by becoming the first nation to successfully test-fire a medium-caliber maritime electromagnetic railgun from an offshore platform. Following this success, the Japan Maritime Self-Defense Force (JMSDF) is now considering the development of a new class of destroyers equipped with electromagnetic railguns.

The 13DDX future destroyer concept, developed by the Ministry of Defense’s Acquisition, Technology & Logistics Agency (ATLA), gained momentum after the successful railgun tests. In May 2024, Vice Admiral Imayoshi Shinichi, ATLA’s Director General of Naval Systems, presented the ambitious plans for the 13DDX at the Combined Naval Event 2024 in Farnborough, UK, where he discussed the future destroyer and submarine projects of the JMSDF.

According to ATLA, the 13DDX—Air Defense Destroyer will be equipped with advanced systems including Rail Guns, Active SAMs, High-Power Lasers, High-speed Maneuvering Target Detection Radar, HPM Weapons, a Fire Control Network, IPES (Downsizing Large-Capacity GEN), AI-based CDS, Autonomous Navigation, Automated Damage Control, and modular mission capabilities.

The 13DDX will also feature directed energy weapons (DEW) and a new multifunction radar optimized for detecting high-speed targets. It will incorporate elements from the JMSDF’s Asahi-class destroyers and Mogami-class frigates.

In early 2022, the Japanese Ministry of Defense decided to develop an electromagnetic weapon system to intercept hypersonic missiles. By 2023, ATLA successfully tested this system, marking the first maritime railgun test ever conducted. Railguns use electromagnetic energy to fire projectiles at speeds around Mach 7, targeting ships, missiles, and aircraft without the need for gunpowder or explosive propellants.

A railgun can theoretically fire a projectile the size of a bowling ball fast enough to destroy a small building over long distances. Due to their significant power requirements, railguns are typically large and not portable, though there are proposals to adapt this technology for non-weapon uses such as launching aircraft and spacecraft.

The medium-sized electromagnetic railgun prototype developed by ATLA, first seen in May 2023, can fire 40mm steel rounds weighing 320g (0.7lb). The railgun uses five megajoules (MJ) of charge energy to fire bullets at speeds around 2,230m/s (Mach 6.5). ATLA aims to eventually operate the railgun on 20 MJ of charge energy.

Japan plans to deploy the railgun both on land and at sea. Initially, the Aegis Ashore land-based system was intended to enhance ballistic missile interception capabilities, but this plan was abandoned in 2020. The development and testing of railguns come as Japan seeks to counter the threat from hypersonic weapons developed by China, North Korea, and Russia.

Admiral Shinichi emphasized the need to enhance Japan’s long-range air defense capabilities in response to the challenging security environment and growing anti-access/area denial (A2/AD) capabilities of other countries.

Japan is accelerating the development of formidable firepower due to the tense geopolitical landscape in East Asia. In May 2024, Japan entered a railgun cooperation agreement with France and Germany to jointly explore and deploy this advanced technology. Meanwhile, China faced setbacks in its own electromagnetic hypersonic railgun testing.

Japan is bolstering its defense capabilities with the development of the 13DDX and its electromagnetic railgun technology, signaling a new era in naval warfare. Japan also plans to mount railguns on land-based trucks, creating a mobile defense network capable of intercepting hypersonic missiles. As tensions rise in the Indo-Pacific region, the world will be watching Japan’s naval transformation closely.

China Captures US Anti-Submarine Device Deployed by US Navy's P-8A Poseidon in South China Sea

 The U.S. Navy's advanced P-8A Poseidon maritime patrol aircraft recently deployed a hydroacoustic buoy in the South China Sea, which has reportedly been retrieved by Chinese forces. This buoy, designed for submarine detection, poses significant concerns over potential reverse engineering by China, which has a history of replicating American technology.

A video posted by Yuyuan Tantian, a social media account linked to the state-run China Central Television, shows what appears to be a U.S. Navy P-8A Poseidon dropping multiple cylindrical devices into the sea. Reports suggest that one of these devices fell near the Second Thomas Shoal in the Spratly Islands, an area contested by the Philippines and China and the site of recent clashes.

Following the incident, the China Coast Guard quickly arrived to retrieve and inspect the unidentified electronic devices, according to Yuyuan Tantian. The video further shows labels on an electronic device identifying Ultra Electronics, a UK-based defense contractor, as the manufacturer. Ultra Electronics specializes in producing radars and electronic warfare products, including sonobuoys.

Sonobuoys are specialized buoys equipped with acoustic sensors designed to detect submarines. When deployed from aircraft like the P-8 Poseidon, they form a network of listening devices that monitor underwater sounds. Passive sonobuoys listen for sounds emitted by submarines, while active sonobuoys emit sound pulses and listen for echoes from objects, including submarines. These devices descend to a predetermined depth using a parachute and then activate their sensors. The data collected is transmitted back to the P-8 Poseidon via radio signals for analysis.

Reverse engineering a captured U.S. sonobuoy could reveal crucial details about American anti-submarine warfare technology. Key areas of interest include the sonobuoy's sensor technology, data processing, communication with the P-8 Poseidon, power management, and any unique software or algorithms used for signal processing and data encryption.

It's challenging to verify China's claims about capturing the sonobuoy, and the specific type of sonobuoy captured remains unknown. Common sonobuoys used by the P-8 Poseidon include the AN/SSQ-53F DIFAR, AN/SSQ-62E DICASS, AN/SSQ-101 ADAR, and the AN/SSQ-125 MAC. These devices, made by companies like Ultra Electronics, Sparton Corporation, Lockheed Martin, and ERAPSCO, provide sophisticated capabilities for detecting and tracking submarines.

US Marines Successfully Conduct First Overseas Ship-to-Shore Operations with New Amphibious Combat Vehicles in Okinawa

 

On June 24, 2024, the US Marine Corps conducted its first overseas ship-to-shore operations with the new Amphibious Combat Vehicles (ACVs) at the White Beach Naval Facility in Okinawa, Japan. This event also marked the debut of the ACVs for the Marines stationed in Okinawa. The Marines and sailors from the 15th Marine Expeditionary Unit (MEU) reached White Beach, partly traveling on the newly deployed ACVs.

The 15th MEU embarked on the amphibious dock landing ship USS Harpers Ferry (LSD 49) and arrived at White Beach on June 18 for a port visit and essential sustainment training. During the operation, personnel boarded the ACVs, which emerged from the well deck of the Harpers Ferry. Boats from the 3rd Expeditionary Operations Training Group then transferred personnel to a pier, simulating safety egress procedures.

After the personnel transfer, the ACV Platoon navigated through the boat basin to come ashore at White Beach for maintenance.

Lt. Col. Nick Freeman, commanding officer of BLT 1/5, 15th MEU, noted that while the training was standard, it was significant as the first overseas ship-to-shore deployment of ACVs. He highlighted the ongoing training at various locations to refine the use of ACVs in their intended environments.

Prior to the ship-to-shore movement, the Marines showcased the ACVs on the Harpers Ferry to other Marine units and members of the Japan Self-Defense Force. Rear Adm. Chris Stone, commander of Task Force 76 and Expeditionary Strike Group 7, praised the ACVs as a "force multiplier" that enhances operational flexibility and response capabilities in maritime environments.

The ACVs' first operational deployment occurred in May during the Balikatan exercise in the Philippines, where they were used in live-fire exercises. The ACV platoon launched from the USS Harpers Ferry, organized into assault sections, and engaged shore-based targets using their Remote Weapons Systems with Mark 19 40 mm grenade machine guns.

The US Marine Corps is transitioning to the ACV to replace the older amphibious assault vehicles, following a tragic accident in 2020 that resulted in the deaths of eight Marines and a Navy corpsman. Developed by BAE Systems, the ACV has faced challenges, including rollovers during training exercises, which led to operational restrictions.

The Marine Corps has identified inadequate training on the ACV’s operational differences from its predecessor as a cause of these incidents. The ACV features wheels instead of tracks, a flatter hull, and a smaller size. Concerns have been raised about the ACV's wheeled design not providing a speed advantage over the older tracked vehicles in water. The Marine Corps aims to address this with a "Phase 2" ACV that may meet performance requirements.

Despite these challenges, the eight-wheeled ACV significantly enhances the Marine Corps' capability to transport troops to shore, navigating through surf during assaults and landings. This deployment marks a critical step in modernizing the Marine Corps' capabilities in the Pacific theater, a strategic focus as they prepare for potential large-scale conflicts where amphibious operations will be crucial.

Philippines Seeks Urgent Talks with China Amid South China Sea Tensions Over Sierra Madre Outpost

The Philippines is urgently seeking to schedule a call with China to address rising tensions in the South China Sea, according to the country's ambassador to the US. The conflict centers around the Sierra Madre, a decaying World War II-era ship grounded on the Second Thomas Shoal, which the Philippines uses as an outpost and resupplies monthly.

Despite a 2016 UN ruling against China's territorial claims, China asserts the area as its own and has increasingly harassed Filipino supply ships. This harassment escalated on June 17 when Chinese sailors boarded Filipino vessels, damaging equipment and injuring eight personnel. One Filipino lost his thumb, leading to a hospital visit from President Ferdinand Marcos Jr., who recently stated that a Filipino death in such confrontations would be considered "very close" to an act of war.

Such a scenario could invoke the mutual defense treaty with the US, potentially involving America in the conflict. US Secretary of Defense Lloyd Austin affirmed America's strong commitment to the treaty but did not provide further comments.

Philippines Ambassador Jose Manuel Romualdez, speaking to reporters in Washington, noted that efforts are underway to de-escalate tensions, including scheduling a call with Chinese counterparts by early July. He emphasized the need for a frank discussion with China to reduce tensions.

Romualdez also confirmed that the Philippines has reinforced the Sierra Madre to improve conditions for stationed soldiers, despite China's objections. He reiterated that the Philippines has no plans to abandon the outpost.

On Wednesday, Austin reaffirmed America's support for the Philippines in a call with his Manila counterpart. The US and the Philippines have strengthened their security relationship over the past year, with the US gaining access to four new military sites in northern Philippines and expanding the "Balikatan" military exercise. The US also deployed a mid-range missile system to the Philippines for the first time in April.

Despite Beijing's objections, the Philippines maintains that the new security agreement is defensive. In April, the US approved a substantial security funding package, including $4 billion for the Indo-Pacific, with a significant portion likely headed to Taiwan and potentially the Philippines.

Ambassador Romualdez emphasized the need for decisive action from all parties involved to address the situation. 

US and Canadian Navies Conduct Bilateral Operations in South China Sea Amidst Tensions with China

 From June 18 to June 20, the United States Navy and the Royal Canadian Navy executed bilateral operations in the South China Sea, emphasizing their strong dedication to regional security and collaboration amid ongoing tensions between China and the Philippines.

The operations included the US Navy’s Arleigh Burke-class guided-missile destroyer USS Ralph Johnson (DDG 114) and the Royal Canadian Navy’s Halifax-class frigate HMCS Montreal (FFH 336). These activities encompassed personnel transfers, flight operations, and replenishment at sea, supported by the Lewis-and-Clark class dry cargo ship USNS Wally Schirra (T-AKE 8).

"Close coordination with our allies and partners is paramount to success in the region," stated Capt. Justin Harts, Commander of Destroyer Squadron 15. "Demonstrating regional cooperation with the Royal Canadian Navy is key to ensuring a free and open Indo-Pacific."

Cmdr. Isaia Infante, commanding officer of the USS Ralph Johnson, underscored the importance of joint exercises, highlighting the opportunity to work closely with allies and partners and reinforce the already strong relationship with the Royal Canadian Navy. He affirmed the crew's commitment to maintaining peace and stability in the Indo-Pacific while supporting the rules-based international order.

The US Navy noted that such bilateral engagements are vital for training, exercising, and developing tactical interoperability across allied navies, enhancing collective readiness to address regional contingencies.

This operation followed a historic joint patrol involving Canada, Japan, and the US with the Philippines in the South China Sea, part of a multilateral maritime cooperation activity (MMCA) aimed at preserving freedom of navigation and overflight. Canada's increasing involvement in the region comes amid reports of aggressive maneuvers by Chinese ships targeting routine resupply missions to a vessel grounded by Manila on the disputed Second Thomas Shoal in the South China Sea. The Philippines has accused China of violating its sovereignty, citing the illegal presence and actions of Chinese vessels within its Exclusive Economic Zone (EEZ).

Canada's recent joint drill with the US Navy could further strain its already fragile relations with China. Since 2018, Canada has intermittently deployed military ships, aircraft, and personnel to conduct surveillance operations to identify suspected maritime sanctions violations, particularly ship-to-ship transfer of fuel and other commodities banned by UN Security Council resolutions.

In June 2022, Canada accused Chinese fighter pilots of dangerously intercepting a Royal Canadian Air Force CP-140 maritime patrol aircraft since December 2021. Reports indicated that Chinese jets intercepted the Canadian aircraft about 60 times, with nearly 20 encounters deemed 'dangerous.' This incident sparked a diplomatic dispute between the two nations. China has consistently criticized Canada for its participation in overflights and freedom of navigation operations alongside the United States, accusing Canadian military aircraft of conducting provocative reconnaissance activities under the guise of implementing UN Security Council resolutions. China argued these activities were unauthorized and increased the risk of mishaps or conflict.

Relations deteriorated further in 2023 when Canada accused China of election interference, leading to reciprocal expulsions of diplomats. Canadian Prime Minister Justin Trudeau confirmed that China attempted to influence the 2019 and 2021 elections, though these efforts were unsuccessful. In military assessments, China and Russia were identified as Canada’s primary adversaries, highlighting the need for a robust response to hostile actions.

US to Supply Taiwan with 1000 Armed Drones Amid Rising Tensions with China

 The United States has approved a $360 million sale of over 1,000 small armed drones to Taiwan, significantly enhancing Taiwan's asymmetric defense strategy against China. The U.S. Defense Security Cooperation Agency (DSCA) announced on June 18 that Taiwan will receive 720 Switchblade drones and related fire control systems valued at $60.2 million. Additionally, Taiwan will acquire up to 291 Altius 600M loitering munitions and associated components for $300 million.

This sale comes as Taiwan awaits previously ordered military equipment, including Abrams tanks, F-16 Vipers, and advanced munitions from Washington. Despite adhering to the 'One China' principle, the U.S. is legally obligated to provide Taiwan with defensive tools against Chinese aggression. This arms sale has drawn criticism from Beijing, which accuses the U.S. of turning Taiwan into a "powder keg."

The drone sale is crucial for Taiwan's asymmetric warfare strategy, which relies on unconventional weapons to deter a Chinese invasion. Taiwan's National Defense Report emphasizes increasing resilience and self-sufficiency, prioritizing domestic defense, and enhancing its "all-out defense" capabilities.

The U.S. Indo-Pacific Command's "Hellscape" strategy aims to deploy drones to distract China during a Taiwanese invasion, allowing U.S. forces time to respond. Admiral Samuel Paparo outlined this strategy, which involves flooding the Taiwan Strait with unmanned submarines, surface ships, and aerial drones to impede a Chinese invasion fleet.

Taiwan's recent interest in drones was likely influenced by their successful use in Ukraine, where U.S.-supplied Switchblade UAVs helped repel Russian forces. Taiwan has also developed its own drones, such as the Chien Hsiang loitering munitions, capable of targeting diverse radar systems deployed by China.

The Switchblade 300, known for its low-cost, lightweight, and precision-guided capabilities, can be deployed quickly from various platforms and has a range of 30 kilometers. Its unique abort function allows it to self-destruct if necessary, minimizing casualties.

The Altius-600M loitering munition, larger than the Switchblade 300, can be launched from land, air, or sea and features multiple seekers and warhead options. It boasts twice the loitering time and range of current loitering munitions and can operate in swarms, enabling a single operator to control multiple drones simultaneously.

Taiwan thanked the U.S. for the drone sale, marking the 15th arms deal between the two since 2021. Taiwan's Presidential Office spokesperson, Karen Kuo, emphasized the importance of strengthening self-defense and asymmetric warfare capabilities to uphold democracy and international order.

Marines' Landing Ship Delayed and Over Budget: Navy Faces Costly Challenges

 The development of a crucial vessel for the Marine Corps, intended for potential conflicts in island regions such as the Pacific, is experiencing significant delays and cost overruns. Originally planned for delivery in 2023, the Navy's landing ship medium program will now award its design and construction contract in fiscal year 2025, two years later than expected, according to the Government Accountability Office’s Annual Weapons Systems Assessment.

Initiated in 2020 to procure 35 stern landing vessels, the project aims to create ships that blend commercial design elements to reduce detectability and enhance maneuverability for Marine littoral regiments. Currently, testing is being conducted using a modified commercial watercraft capable of direct beach landings.

Assistant Commandant Gen. Christopher Mahoney explained the ship's role: "It is a shore-to-shore logistics connector to transport heavy items that can't be flown in or brought by larger ships, allowing maneuvering and sustaining positions."

Key features of the landing ship medium include:

• Length: 200 to 400 feet
• Draft: 12 feet
• Crew: Approximately 70 sailors
• Capacity: 50 Marines and 648 short tons of equipment
• Deck cargo space: 8,000 square feet
• Speed: 14 knots with a cruising range of 3,500 nautical miles
• Beach landing capability: Roll-on/roll-off for 1:40 grade beaches
• Helicopter pad
• Armament: Two 30 mm guns and six .50-caliber guns
• Service life: 20 years

The first of three planned regiments became operational in 2023. However, the Navy is devising a bridging strategy as it continues to experiment with modified commercial vessels. These interim solutions require significant modifications, each costing around $115 million.

A Congressional Research Services report updated in April suggested that Congress could consider adapting the Army's existing fleet of logistics support vessels to meet some Marine requirements. The Army, with over 100 such vessels, has shifted its logistics focus to the Pacific, aligning with Marine needs.

The Navy plans to award the construction contract in March 2025, with the first ship expected by January 2029. Operational testing is slated for completion by July 2030, with initial capability projected for December 2034.

The program's costs have escalated significantly. The Congressional Budget Office estimates the initial 18-ship program to cost between $6.2 billion and $7.8 billion, or $340 million to $430 million per ship. This is nearly triple the original estimate of $2.6 billion, or $150 million per ship. Should the Navy procure the full fleet of 35 landing ships, the total cost could reach between $11.9 billion and $15 billion.

Chinese Researchers Analyze F-35 vs. F-22: Which Stealth Fighter Poses a Greater Threat to PLAAF?

 Recently, US Indo-Pacific Command's Admiral Samuel Paparo discussed a “Hellscape” strategy to counter China, predicting a strong drone force could severely challenge any Chinese invasion of Taiwan. General Kenneth Wilsbach, Commander of the Pacific Air Forces, argued in March 2022 that using expendable unmanned aircraft against China would be more effective than deploying high-end stealth fighters like the F-35s or F-22s.

While many analysts view the F-22 Raptors as the primary threat to Beijing, Chinese researchers have a different perspective. In April last year, they conducted a study comparing the US stealth fighters F-35 and F-22, concluding that the F-35 Lightning II presents a greater threat than the F-22 Raptors.

Despite the F-22’s reputation as a formidable stealth aircraft, the study published in the Chinese-language journal Modern Defense Technology found the F-35 poses a more significant threat to Chinese military defenses. The research evaluated the impact of these aircraft during various stages of a counter-air operation near China’s coastline.

The study suggests that the F-35A, with its advanced avionics and multirole capabilities, is more adaptable and effective in potential conflicts in the Indo-Pacific region. Researchers noted that the F-35's ability to perform multiple functions and its versatility in various missions give it an edge over the F-22.

The F-35 has become a vital asset in the region due to its advanced technology and remarkable adaptability. The US and its allies operate many F-35s near China, whereas the F-22s are fewer in number and solely operated by the US Air Force, often on a rotational basis. By 2035, over 300 F-35s are expected to be deployed in the Indo-Pacific, with operators including Australia, Japan, Singapore, South Korea, and the US.

To counter the F-35 threat, Bao Junchen from the National University of Defense Technology and a team from the People’s Liberation Army’s Unit 31649 in Guangdong propose a dual strategy. They recommend enhancing electronic warfare capabilities for "soft kill" actions and developing physical weapons for "hard kill" responses. The F-35A's roles as both an intelligence-gathering sensor and a primary escort for forward attacks call for both non-destructive and destructive countermeasures.

China views the US’s penetrating counter-air operation strategy as a significant threat and is heavily investing in military capabilities to counteract US power in the Asia-Pacific. The US maintains a strong military presence in the region, with bases in Japan, South Korea, and Guam. In response, China has deployed advanced systems like the HQ-9 missile system and the J-20 stealth fighter, increasing production of the latter.

These weapons are intended to counter US air defenses and target high-value assets such as airfields and command centers. The study emphasizes that analyzing the F-22 and F-35 can help China develop effective countermeasures and protect its airspace. Additionally, the research advocates for a coordinated strategy to counter B-2 and B-1B bombers, which pose a threat when penetrating deeper into Chinese territory. A multi-dimensional approach using various platforms from air, land, sea, and space is recommended.

Although the study found the MQ-9 drone less threatening, it warned against ignoring advanced drones like the XQ-58A and RQ-180. The researchers used an analytic hierarchy process (AHP) to evaluate each aircraft’s threat level, offering a nuanced assessment. However, the lack of raw data due to military sensitivity makes independent verification challenging.

USS Connecticut Submarine Accident Highlights Detection Vulnerabilities in South China Sea

 

The USS Connecticut, a Seawolf-class nuclear attack submarine, encountered a significant mishap during a classified mission in October 2021, revealing vulnerabilities despite its advanced stealth technology. This incident, which took place in the South China Sea (SCS), led to extensive investigations aiming to uncover the reasons behind the accident.

On the fateful day, the USS Connecticut struck a seamount while cruising at high speed in the northern SCS, tarnishing the reputation of one of the US Navy's most powerful and expensive submarines. The incident prompted calls for a thorough investigation, especially given China's criticism of the US's opaqueness and irresponsibility regarding the event's specifics.

A recent Chinese study, led by engineer Li Yuhang of the 713th Research Institute of China State Shipbuilding Corporation, provided new insights. The researchers used real-world data from Chinese sensors in the SCS to examine water surface wakes. Published in the Chinese Journal of Theoretical and Applied Mechanics on May 27, the study found that submarines like the SSN-22, traveling at depths of 100 meters and speeds over 20 knots, can create detectable surface ripples, potentially revealing their position.

This groundbreaking finding challenged previous assumptions about modern submarine invincibility and highlighted the delicate balance of power in the region. The study's results were the first to use real SCS data to systematically analyze the water surface response to submarine movement.

The US Navy's investigation into the accident identified multiple failures in navigation planning, execution, and risk management as the cause. The investigation revealed that the USS Connecticut’s navigation review team had failed to identify and mark at least ten underwater hazards and had incorrectly assessed the operating area as open. This led to a significant period of inactivity for the submarine due to damage, with eleven sailors sustaining minor injuries.

The incident also reignited US-China tensions over territorial claims in the South China Sea. On October 2, 2021, the USS Connecticut struck an object in international waters during China's National Day celebrations, coinciding with heightened military drills by the People's Liberation Army (PLA) near Taiwan. The PLA's air activity saw a significant increase, escalating tensions further.

Technological advancements in wake detection have also played a role in understanding the incident. Recent progress in AI and anti-submarine radar technology, including the development of a 6G radar capable of detecting minute submarine ripples, has improved the ability to locate submarines. Chinese researchers reported a 96 percent accuracy rate in detecting submarine wakes using AI, highlighting the growing sophistication of detection systems.

In conclusion, the USS Connecticut's collision has underscored the evolving dynamics of undersea warfare, where stealth alone is no longer sufficient. The incident has marked a significant moment in the race for technological superiority in the challenging environment of the South China Sea, influencing the future of submarine operations.

White House Criticizes Shipbuilding and Defense Measures in FY25 Defense Bill

 

The White House issued a statement on Tuesday critiquing various elements of the House’s fiscal 2025 defense policy bill ahead of upcoming votes.

While the statement commended the House Armed Services Committee for its bipartisan efforts on the $884 billion bill, it highlighted concerns over provisions related to shipbuilding, the formation of an Army drone corps, missile defense, and pricing transparency for defense contractors.

The White House also pressed Congress to establish an Indo-Pacific Security Assistance Initiative, which the bill lacks despite a Pentagon request for a program similar to the one aiding Ukraine.

“The administration looks forward to continuing to work with Congress to set appropriate and responsible levels of defense and non-defense spending to support the security of the nation,” stated the White House’s Office of Management and Budget, expressing a desire to collaborate on addressing concerns.

Despite its objections, the White House did not issue a veto threat but warned that this could change if the House adopts certain socially conservative amendments proposed by the Republican right-flank during this week’s votes.

Last year, Republicans adopted a similar strategy, turning a bipartisan bill into a partisan one with amendments from the Freedom Caucus. However, these provisions were removed during Senate negotiations, resulting in a bipartisan compromise bill for FY24 in December.

The Senate Armed Services Committee is set to mark up its version of the FY25 defense policy bill later this week.

House Armed Services Chairman Mike Rogers (R-Ala.) and Rep. Adam Smith (D-Wash.), the committee’s top Democrat, urged the Rules Committee to prioritize non-divisive amendments out of the 1,386 proposed.

“The bill we are presenting today is truly bipartisan,” said Rogers, noting that it advanced 57-1 last month. Smith added that efforts to restrict reproductive healthcare or LGBTQ rights would pose significant problems, as would any attempt to block the Department of Defense’s inclusivity efforts.

Shipbuilding Disagreements

Aside from potential social policy conflicts, the Armed Services Committee is at odds with defense appropriators over their draft spending bill, which overrides several provisions in the defense policy bill. For instance, the draft FY25 defense spending bill does not fund the policy bill’s $1 billion authorization for a second Virginia-class attack submarine, aligning with the White House and Navy’s decision to fund only one due to production delays.

“The authorization of incremental funding for a second [Virginia-class submarine] would result in a significant unplanned bill in FY26,” noted the White House statement. The Biden administration encourages Congress to support near-term submarine industrial base investments instead.

The Armed Services Committee argues that dropping a second Virginia-class vessel in FY25 will set back companies further down the submarine supply chain. The defense policy bill also cuts $1.17 billion in procurement of a frigate for FY25, drawing further White House objections.

Additionally, the White House opposed a provision blocking the retirement of guided-missile cruisers, arguing that ships like the USS Shiloh and USS Lake Erie are too costly to modernize and restore.

Army and Missile Defense

The White House strongly opposes the bill’s provision to create a drone corps within the Army, citing concerns over specialization and flexibility. It also opposes establishing a third continental missile interceptor site on the east coast by 2030, arguing there is no operational need for such a site, with 20 Next-Generation Interceptors to be fielded in Alaska by 2028.

Defense Contractor Pricing Data

The White House also objects to a provision raising the cap for obtaining certified cost or pricing data from subcontractors to $5 million, up from $2 million. This change would reduce the incentive for prime contractors to negotiate fair contracts with subcontractors, creating unnecessary taxpayer risks.

The Project on Government Oversight, a watchdog group, also opposes this provision, arguing it would allow prime contractors to provide outdated historical data to justify price hikes, complicating the contracting officers’ ability to determine fair pricing.

US Admiral Reveals “Hellscape” Drone Warfare Strategy to Counter China’s Taiwan Invasion Plan

 

The United States is developing a strategy to deploy a vast array of drones to counter a potential Chinese invasion of Taiwan. This plan, referred to as the "Hellscape" strategy, aims to use drones to overwhelm and distract Chinese forces, buying crucial time for US and allied forces to mount a full-scale response.

Admiral Samuel Paparo, the commander of US Indo-Pacific Command, outlined this approach at the International Institute for Strategic Studies’ Shangri-La Dialogue Summit. The strategy involves deploying thousands of unmanned submarines, surface ships, and aerial drones as soon as China’s invasion fleet begins crossing the 100-mile Taiwan Strait.

China recently conducted military drills following the inauguration of Taiwan’s new president, intensifying its calls for reunification with Taiwan. US President Joe Biden has hinted at military support for Taiwan in the event of an invasion, which could escalate into a larger US-China conflict involving Washington's regional allies. This makes it essential for the US to develop effective countermeasures against Chinese forces in the Taiwan Strait.

The "Hellscape" strategy heavily relies on autonomous systems, a tactic influenced by the recent war in Ukraine. In Ukraine, drones have been used to launch strikes on control centers, refineries, airfields, and ships, demonstrating that modern air defenses are not impenetrable. This has reshaped how militaries approach modern warfare, with a focus on cost-effective, reusable, and disposable drone technology.

General Kenneth Wilsbach, Commander of the Pacific Air Forces, initially proposed using "attritable" unmanned aircraft against China instead of high-end stealth fighters like the F-35s or F-22s. These lower-cost, disposable drones would serve as decoys, gradually wearing down Chinese defenses by creating numerous targets.

The Pentagon is actively working on this drone warfare strategy, planning to spend $1 billion on the Replicator program this fiscal year. This program aims to rapidly scale and deploy thousands of autonomous systems within the next 18 to 24 months, utilizing AI, robotics, and commercial technology. The Pentagon is also collaborating with defense partners to develop and procure these critical systems.

Deputy Secretary of Defense Kathleen Hicks emphasized the need to counter China’s mass with a mass of drones that are more challenging to target. The US Navy is also working on developing swarming drones, including underwater drones, to counter the numerical superiority of the Chinese PLA Navy in the Indo-Pacific region.

Admiral Paparo highlighted the strategic advantage of US unmanned capabilities, stating that these systems would amplify US advantages in the region. He noted that recent Chinese military drills appeared to be rehearsals for a Taiwan invasion, which the US observed and learned from.

In response to these developments, China has expressed dissatisfaction. The state-owned Global Times criticized the US strategy, suggesting it was a desperate attempt to maintain its dominance and incite Taiwan’s independence efforts.

Philippines Replaces India as Key US Military Partner Against China: Can Manila Succeed Where Delhi Hesitated?

 As China emerges as a global economic and military power capable of challenging US dominance, the Indo-Pacific region, including the Indian Ocean Region (IOR), has gained significant strategic importance for US defense. The Indo-Pacific would become a pivotal battleground if Western powers, led by the US, were to confront China.

Initially, there was debate over whether India should be included in the Indo-Pacific initiative, given its long-standing ties with Russia. However, China's aggressive actions along the Himalayan border with India eventually led Prime Minister Modi to support India's inclusion in the Quad, bolstering the initiative's prospects.

India focused on modernizing its navy to protect its shores and ports, while the Quad countries also worked on enhancing their naval capabilities. In April 2024, the navies of the US, Australia, Japan, and the Philippines conducted joint maritime exercises in the South China Sea, aiming to strengthen their collective ability to uphold freedom of navigation and maritime rights.

From April 22 to May 8, US and Philippine ships, alongside French and Australian naval troops, conducted the Balikatan 2024 exercise with over 16,000 participants. Although not officially aimed at containing China, these exercises sent a clear message of US presence near Chinese waters.

One controversial mission during the exercise involved sinking a decommissioned China-made naval vessel, BRP Lake Caliraya, which Beijing viewed as a deliberate message.

During the Balikatan exercise, defense ministers from the four countries met in Honolulu, discussing the exercise's political implications near China's coast. Reports suggest that the term "Squad" was informally used to describe the four participating countries, hinting at a new East Asian bloc.

The Quadrilateral Security Dialogue (Quad), comprising Australia, India, Japan, and the US, was initially established in 2007. However, it remained largely inactive until 2017 when Quad leaders met in Manila to revive the initiative with a stronger stance against China, driven by concerns over China's Belt and Road Initiative and US accusations of "predatory economics."

Despite pressure from Washington, India maintained a pragmatic stance, continuing to purchase discounted oil from Russia and declining to align fully with NATO's anti-China agenda. This led the US to shift focus from the Quad to the more cooperative government of the Philippines.

Ultimately, US efforts to coerce India into a confrontational position against China failed, as India joined the Quad to enhance trade relations and ensure free maritime movement. The effectiveness of the newly formed "Squad" in ensuring Indo-Pacific security remains to be seen.

US Navy and Taiwan Conduct Unplanned Military Exercises in West Pacific Amid Rising Tensions with China

 

In an unannounced move showcasing growing maritime cooperation, the U.S. and Taiwan conducted impromptu military exercises in the West Pacific. This development comes amid rising tensions between Taiwan and China, ahead of the inauguration of Taiwan's president-elect, Lai Ching-te. According to unnamed sources cited by Reuters, the drills took place during routine naval encounters.

One source mentioned the involvement of “multiple military assets,” while another highlighted that these exercises were unofficially termed “unplanned sea encounters,” implying a tacit agreement that these drills were coincidental rather than premeditated.

These exercises occurred between a series of scheduled high-profile drills. In mid-April, the U.S. conducted a trilateral exercise with Japanese Maritime Self Defense Force (JMSDF) and Republic of Korea Navy (ROKN) vessels, focusing on interoperability and warfighting capabilities. Shortly after, the Balikatan 24 exercise in the Philippines involved the U.S., Philippine, Australian, and French forces, concentrating on counter-landing operations and maritime domain awareness.

During the unplanned U.S.-Taiwan drills, around six ships, including supply vessels and frigates, engaged in basic communications, resupply operations, and joint anti-submarine warfare (ASW) exercises. These drills are critical for ensuring operational compatibility between the two navies in emergencies, involving tactical maneuvers and underwater target searches.

Taiwan's Ministry of National Defense spokesperson, Major General Sun Li-fang, stated that the exercises adhered to the Code for Unplanned Encounters at Sea (CUES), which manages interactions between different militaries at sea. This protocol was previously utilized in 2016 during an encounter between the USS Chafee and three ROCN ships.

The disclosure of these exercises follows Taiwanese Chief of General Staff Admiral Mei Chia-shu’s visit to the U.S. Indo-Pacific Command (USINDOPACOM) change of command ceremony in Hawaii in early May. Shortly after, China conducted significant military exercises around Taiwan, labeled “Joint Sword-2024A,” which involved near-encirclement maneuvers similar to those after Nancy Pelosi's visit in 2022.

In late May, the U.S. began Tiger Strike 2024 with Malaysia, focusing on amphibious warfare and multi-domain awareness. Early June saw the announcement of the “Freedom Edge” exercise, a first-time trilateral drill involving the U.S., Japan, and South Korea.

These high-profile activities in the West Pacific lead up to the Rim of the Pacific 2024 (RIMPAC 24) exercises, scheduled from June 28 to August 2, involving 29 nations, 40 surface ships, 3 submarines, 14 national land forces, over 150 aircraft, and more than 25,000 personnel. The Italian carrier Cavour and a French Navy FREMM air defense frigate will also participate.

US Air Force Nears Breakthrough in Rapid Electronic Warfare Updates

 The U.S. Air Force is on the brink of being able to update its electronic warfare (EW) systems with new battlefield data in just a few hours, significantly faster than the current process, a key commander said on Wednesday.

Col. Josh Koslov, head of the 350th Spectrum Warfare Wing, has aimed for a rapid three-hour update window for EW systems, a goal he once considered a “moonshot.” Speaking in a webcast hosted by C4ISRNET, Koslov revealed that this target is now within reach.

“We're very close to that, if not already achieving it, for most systems under the spectrum warfare wing,” said Koslov. He noted that more than half of the 70 EW systems managed by his wing can now be updated in three hours or less.

However, many of these systems have unique characteristics, and Koslov emphasized the need for interoperability and open architecture standards to streamline rapid data updates. To support this, the Air Force must develop data production methods that can handle large-scale data processing and quickly relay updates to the field.

Koslov and Brig. Gen. Ed Barker, the Army’s program executive officer for intelligence, electronic warfare, and sensors, discussed the necessity of swift updates to EW systems in future conflicts against advanced adversaries, where battlefield conditions and threats change rapidly.

“Data is the weapon,” Koslov stated. “We must continue to pressure the adversary to gain an advantage and achieve our objectives. Data processing is the key to making that happen.” This involves integrating data from all sources within the joint force, analyzing it to identify new threats, and developing countermeasures to deploy swiftly.

To achieve rapid updates, the Air Force has revised its tactics, techniques, and procedures with a stronger focus on warfighting. Whether updates can be made remotely or require physical connection depends on the specific EW system, with data being processed at locations like Eglin Air Force Base or other reprogramming centers.

This capability will be crucial in major conflicts, such as those involving China or North Korea, where joint forces would be dispersed across the Pacific. “It’s not effective if a new capability is limited to one area,” Koslov said. “We need to distribute it across the force, and centralizing the process is the way to do that moving forward.”

Since its activation in 2021, the 350th Spectrum Warfare Wing has expanded its capabilities, recently adding two new squadrons: the 388th at Eglin and the 563rd at Joint Base San Antonio-Lackland. The 563rd focuses on developing new EW software for operational units, while the 388th studies adversaries like China to find ways to counter their digital capabilities.

The wing’s next objective is to build the 950th Spectrum Warfare Group at Robins, set to be fully operational by 2027. This group will assess and enhance EW systems in Air Force combat aircraft. “We need to evaluate the performance of our platforms and our tactics, techniques, and procedures to ensure we are effective in the EW spectrum,” Koslov concluded.

Italian Navy Deploys Carrier Strike Group for Five-Month Indo-Pacific Mission

 

The Italian Navy's Carrier Strike Group, led by the Cavour (CVH 550) STOVL aircraft carrier and accompanied by the Alpino (F 594) Bergamini-class frigate, embarked on a five-month deployment to the Indo-Pacific region on June 1st. This mission was confirmed by Italian Navy Chief of Staff Admiral Enrico Credendino at the Conference Navale de Paris in January, though the Ministry of Defense has not released detailed information.

During this deployment, the Carrier Strike Group will visit around ten countries and ports, traveling through the Mediterranean Sea, Indian Ocean, Red Sea, and Gulf of Aden to reach the Pacific. The group will operate in the Indo-Pacific for approximately two months before returning to Italy, making stops in Southeast Asia, India, and the Middle East.

Admiral Credendino emphasized that the Cavour Carrier Strike Group is a versatile tool for projecting power globally, maintaining sea control, and ensuring open sea lines of communication. The deployment will achieve initial operating capability (IOC) for the Italian Navy’s fifth-generation aircraft, enhancing interoperability with allies.

The Cavour carries an air group including Lockheed Martin F-35B Lightning IIs, Boeing AV-8B Harrier II Plus aircraft, and NH90 helicopters, totaling more than a dozen assets, with expectations of increased numbers during the mission. The Alpino frigate provides anti-submarine warfare capabilities, and the group will expand with NATO, EU, and allied naval assets, including Spanish and French frigates.

The Italian Carrier Strike Group will engage in naval diplomacy, promote Italian industry, and collaborate with NATO and local navies. Highlights include the biennial Pitch Black exercise in Australia, interactions with the US Armed Forces in the Central Pacific, and engagements with the Japan Maritime Self-Defense Force. The group will visit the Philippines, Indonesia, Singapore, India, Oman, Pakistan, and Saudi Arabia before returning to Italy in early November.

This mission is crucial for evaluating and qualifying the capabilities of the fifth-generation F-35Bs, aiming to reach IOC by the end of 2024, which is significant for both the Italian Navy and NATO.

China's Expanding 'Carrier Killer' Missiles: A Strategic Threat to US Naval Dominance

 In the midst of global tensions, China's military posturing towards Taiwan intensifies, paralleled by Russia's war against Ukraine. Recently, China's "Joint Sword – 2024A" exercises followed closely after Lai Ching-te's inauguration as Taiwan's President, whom Beijing labels a "separatist."

During these drills, warships patrolled near Taiwan's coast, signaling potential invasion threats that could disrupt the technology supply chain, trigger economic crises, and escalate to a US-China conflict. Beijing justified the drills as a response to Lai's assertion that Taiwan and China are "not subordinate to each other." Taiwan's defense forces tracked 49 Chinese aircraft, 19 naval ships, and 7 coast guard vessels near its waters, indicating the growing threat. Most of these ships were frigates and corvettes with lighter weapon loads.

As tensions rise, the US is preparing for potential conflict. A delegation of US lawmakers has shown support for Taiwan in response to China's extensive military drills. In April 2024, Rear Adm. Mike Studeman, a former US Navy intelligence leader, warned that China's military is preparing for an invasion or blockade of Taiwan within the next decade.

China insists that nations cannot maintain official relations with both China and Taiwan, leading Taiwan to have formal diplomatic ties with only a few countries. The US, while being Taiwan's most crucial ally, does not officially recognize Taiwan, adhering to the one-China principle.

Comparison of Naval Capabilities

As of 2024, China has the world's second-largest navy by total displacement, following the US Navy, and the largest number of active service ships. A report from the US Congressional Research Service highlights that China's navy is the largest in East Asia and surpassed the US Navy in battle force ships between 2015 and 2020. Currently, China has over 370 battle force platforms, including major surface combatants, submarines, amphibious ships, mine warfare ships, aircraft carriers, and fleet auxiliaries. By 2025, this force is projected to grow to 395 ships, reaching 435 by 2030.

China operates two aircraft carriers, the Liaoning and Shandong, with the third and most advanced, the Fujian, starting sea trials in May 2024. In contrast, the US Navy had 292 battle force ships as of January 29, 2024, with a projected fleet of 290 ships by FY2030.

In a potential naval conflict, China would need to reposition military assets to its eastern coast and prepare for an invasion, while using its anti-ship firepower to keep US warships at bay. China's arsenal of anti-ship missiles (ASMs) is central to its strategy to deny US forces access to the Western Pacific.

China’s Anti-Ship Missiles (ASM)

China has significantly expanded its anti-ship ballistic missiles (ASBMs), sometimes called "carrier killers." Key missiles in China’s arsenal include the YJ-12, YJ-18, YJ-83, DF-21, and DF-26.

YJ-83: A modern addition to China's anti-ship arsenal, deployed on surface ships and multirole aircraft. It’s a smaller, shorter-range missile typically housed in box launchers on Chinese frigates and corvettes.

YJ-18: A cruise missile for anti-ship and land-attack roles, derived from the Russian 3M-54E "Klub" missile, and the only widely deployed ASM that can be launched from vertical launch cells. It’s installed on large surface combatants and submarines.

YJ-12: Compatible with various platforms, including bombers and coastal launchers, the YJ-12 can engage warships from long distances.

DF-26: An Intermediate-Range Ballistic Missile (IRBM) that provides high speed and long range, earning the "carrier killer" nickname. It can target beyond aircraft carriers.

DF-21D: A medium-range ballistic missile operational since 2012, designed specifically to target ships at sea, reaching speeds up to Mach 10 during the terminal phase.

China's anti-ship missile capabilities aim to deny US warships access to the region, leveraging Taiwan's proximity to offset American naval dominance.

Taiwan's Strategic Position

As tensions over Taiwan escalate, its strategic position within the "first island chain" becomes crucial. Controlling this link would bolster China's influence in the Western Pacific, challenge US dominance, and give Beijing control over Taiwan's semiconductor manufacturing industry. Given Taiwan's role in maritime trade routes and its semiconductor industry, neither the US nor its allies can afford to let Taiwan fall into Beijing's orbit.
