Northrop Grumman has developed a new gallium nitride (GaN) microwave chip that operates in the W-band spectrum, a high-frequency range used for advanced radar, satellite communications, and emerging wireless networks.

The company said the chip was designed, manufactured, and made market-ready in less than six months, an unusually short timeline for a high-frequency semiconductor intended for defense and commercial applications.

Built at Northrop Grumman’s semiconductor facility in Redondo Beach, California, the chip is designed to strengthen wireless signals while operating at frequencies capable of transmitting large amounts of data with low latency.

According to the company, the technology could support secure military communications, next-generation radar systems, satellite links, and future 5G and 6G wireless networks.

Faster signals, smaller hardware

The W-band occupies frequencies between roughly 75 and 110 gigahertz, offering significantly more bandwidth than lower-frequency wireless systems. The added spectrum can help enable faster data transmission, higher-resolution sensing, and more secure communications.

W-band technologies are attracting growing interest because they can handle far larger amounts of data than many conventional wireless systems. The frequencies are increasingly being explored for applications ranging from high-resolution imaging and advanced sensing to satellite communications and future mobile networks.

However, operating at such high frequencies requires specialized semiconductor materials and designs capable of maintaining performance while managing power and heat, areas where GaN-based devices have gained increasing attention.

Northrop Grumman said the new chip fully utilizes this portion of the radio spectrum to improve signal performance while reducing the need for larger and more power-intensive equipment.

Gallium nitride has become a key material for advanced radio-frequency electronics because it can operate at higher power levels and frequencies than conventional silicon-based devices. The material is already widely used in military radars, electronic warfare systems, and satellite communications hardware.

The company said the chip can act as a signal amplifier, helping wireless systems transmit and receive data more efficiently. In military applications, that could improve secure communications and data transfer between platforms and satellites. Commercially, the technology could help support future wireless networks as demand for higher data rates continues to grow.

Defense To 6G

The project was developed through the California DREAMS hub of the Microelectronics Commons program, a public-private initiative aimed at accelerating domestic semiconductor innovation.

The program is funded by the Office of the Under Secretary of Defense for Research and Engineering and brings together industry, government, and academic partners to speed the development of advanced microelectronics technologies.

Northrop Grumman said the rapid development cycle demonstrates how collaborative manufacturing and design efforts can shorten the path from concept to deployment.

The company manufactures microelectronics at two US-based facilities and produces millions of semiconductor components annually for defense and commercial customers. Its Microelectronics Center has been involved in semiconductor development for more than seven decades.

As governments and industries seek faster communications, more capable radar systems, and advanced sensing technologies, high-frequency GaN devices are expected to play an increasingly important role in future wireless infrastructure.

Saronic and Castelion, two defense technology companies, have announced plans to combine an autonomous warship with a hypersonic strike weapon. They said this is the first attempt to put a hypersonic vehicle on an unmanned surface vessel.

Castelion’s Blackbeard hypersonic system will be launched from Saronic’s Marauder medium unmanned surface vessel, with a demonstration at sea planned for 2027.

By combining an unmanned vessel with a hypersonic strike system, the companies hope to give commanders more choices for future naval missions.

Autonomous vessel meets hypersonic firepower

According to the agreement, Saronic’s Marauder unmanned vessel will launch Castelion’s Blackbeard hypersonic vehicle. The companies said this is an important step toward creating strike systems that work without crews on board.

“Launching a Castelion hypersonic from a Marauder MUSV significantly changes the approach for any adversary calculating where and how the U.S. can strike,” Dino Mavrookas, co-founder and CEO of Saronic, said in a statement. “Deterrence is ultimately a function of capability, capacity, and credibility. Saronic and Castelion are working to increase all three by combining autonomous maritime and hypersonic strike capabilities that are more scalable, more affordable, and faster to field.”

The idea is to equip autonomous ships with advanced weapons that can operate across large areas of the ocean. These ships could offer more launch points for weapons and help keep people out of danger.

Castelion is also increasing production of the Blackbeard system and plans to make several thousand missiles each year. Last October, the company said Blackbeard had won several awards to help it work with both Army and Navy platforms.

Blackbeard production ramps up

By producing more Blackbeard missiles, Castelion hopes to deploy the weapon across more branches of the military. The company says using Blackbeard with Marauder could make operations more flexible and easier to deploy.

“Blackbeard and Marauder will give our warfighters more shots, from more places, with fewer constraints,” Bryon Hargis, co-founder and CEO of Castelion, said in a statement.

This partnership comes as defense leaders look for ways to use more precision strike systems without raising costs. Autonomous ships capable of carrying advanced weapons are becoming an important part of this plan.

Marauder advances toward operational testing

The announcement arrives during a busy period for Saronic. The company is currently expanding a shipyard in Louisiana, a project expected to be completed by the end of this year. Once finished, the facility will have the capacity to produce up to 20 Marauder vessels annually.

Late in May, Saronic revealed that the 180-foot-long Marauder had entered on-water trials. The vessel is designed to carry payloads weighing up to 150 metric tons, giving it the capacity to support a range of military missions.

The U.S. Navy is also evaluating the platform. Last month, the service confirmed that Saronic was among seven companies selected for its MUSV marketplace initiative. Participants will conduct at-sea testing this summer, and those who successfully complete the evaluation phase by October will receive $15 million and become eligible for future production contracts.

Growing role for unmanned naval systems

Beyond Marauder, Saronic has developed several autonomous surface vessels, including the Corsair. According to the company, the vessel can transport payloads of up to 1,000 pounds over distances exceeding 1,000 nautical miles.

The Navy’s Task Force 59, which focuses on unmanned maritime operations in Bahrain, began fielding Corsair vessels in March. The platform recently played a role in a real-world rescue mission.

On Monday, U.S. Central Command said Navy units, including Task Force 59, assisted in rescuing two crew members from a US Army AH-64 Apache helicopter that went down near the coast of Oman.

Bayou Metals, a manufacturing partner of defense shipbuilder Huntington Ingalls Industries (HII), has stood up a dedicated production line for the Romulus uncrewed surface vessel (USV), a move intended to compress delivery timelines and increase throughput for the US Navy’s growing unmanned maritime program.

The production line is located in Slidell, Louisiana. Bayou Metals is also serving as a strategic marine-grade aluminum supplier to the HII. 

A purpose-built line for an uncrewed hull

Rather than routing Romulus components through a generalized fabrication workflow, Bayou Metals configured a dedicated manufacturing line specifically for the vessel’s metalwork and structural assemblies. This single-product-line architecture reduces setup changeover time and allows process engineers to optimize fixturing, weld sequencing, and quality inspection around a single repeating geometry—a standard lean-manufacturing approach when volume and schedule pressure justify the capital allocation.

The Romulus family of USVs is designed for a wide range of mission sets, including intelligence, surveillance, and reconnaissance (ISR), mine countermeasures, strike operations, and counter-unmanned systems. It can also serve as a mother-ship to launch and recover unmanned underwater vehicles (UUVs) and unmanned aerial vehicles (UAVs). It is centered on HII’s Odyssey autonomy software suite and open systems architecture.

HII has been developing the platform as part of the broader US Navy push to field autonomous and semi-autonomous surface vessels capable of operating alongside crewed combatants. Romulus is being developed in partnership with Breaux Brothers, Shield AI, Beier Integrated Systems, and Incat Crowther. 

Supply chain structure for unmanned programs

The Bayou Metals arrangement illustrates how prime defense contractors are structuring supply chains for unmanned platforms differently from traditional crewed ships. Because USVs are expected to be procured in larger numbers at lower per-unit cost than destroyers or frigates, the production economics demand a more industrialized approach from tier-one and tier-two suppliers early in the program lifecycle — before the Navy has necessarily committed to a high-rate production contract.

HII’s unmanned systems portfolio

HII has been expanding its unmanned and autonomous systems work through its Mission Technologies division, positioning itself beyond traditional nuclear shipbuilding. The Romulus program sits within that strategic push.

By anchoring a dedicated supplier line, HII is attempting to demonstrate production readiness — a factor the Navy weighs when evaluating whether a program can transition from development and low-rate initial production to full-rate procurement.

Production readiness reviews assess not just the prime contractor’s internal capacity but the depth and reliability of the supplier base. A named, dedicated manufacturing line at a partner facility is a tangible data point in that evaluation criteria. 

What comes next

In addition to the vessel currently under construction, four additional Romulus 151 vessels will be built by Breaux Brothers Enterprises in Louisiana. This effort for HII also supports the expansion of the U.S. shipbuilding industrial base by growing Gulf Coast manufacturing capacity.

Pokemon Go players' optional location scans reportedly helped train Niantic Spatial's visual positioning system, which uses camera imagery and 3D maps to navigate when GPS is unavailable or jammed. According to DroneXL, that technology is now being paired with Vantor's drone navigation software for military and intelligence use, raising questions about whether gamers understood that footage collected for in-game rewards could eventually support defense systems. From the report: The pipeline runs from a mobile game to the battlefield in three steps. Players scanned the physical world. Niantic Spatial turned those scans into a 3D map that lets a machine locate itself by sight when satellite signals fail. And in December 2025, Niantic Spatial announced a partnership with Vantor, the defense and intelligence firm formerly known as Maxar Intelligence, to fuse that ground-level system with Vantor's aerial navigation software for use in GPS-denied operations. I have spent years covering how drones lose their way the moment an electronic warfare unit switches on a jammer, a problem that has spread from the battlefield into civilian airspace, from Ukrainian workshops cycling through navigation generations to American programs scrambling for alternatives. The unsettling part of this story is not the technology. It is where the training data came from, and whether the people who supplied it would have agreed had anyone explained the destination. "Now as part of Scopely (the Saudi-owned company that acquired Niantic last year for $3.5 billion), Pokemon GO data is not shared with Niantic Spatial," a company spokesperson said in a statement to Kotaku. "AR Scans collected through Pokemon GO were submitted voluntarily by players who opted into the feature and were subject to the applicable Terms of Service and Privacy Policy at the time. The discontinuation of AR scanning and the end of data sharing with Niantic Spatial were part of the transition planning associated with Pokemon GO's move to Scopely."

Autonomous aircraft are increasingly drawing attention as the U.S. military looks for new ways to sustain operations in contested and hard-to-reach environments. Pyka’s latest demonstration suggests those efforts may be moving beyond theory and closer to operational reality.

The California-based company has introduced a precision airdrop capability for its DropShip autonomous aircraft, enabling it to deliver critical supplies without a pilot onboard. Pyka says the system could help U.S. and allied forces move mission-essential cargo across long distances when traditional supply routes become disrupted or unavailable.

The demonstration reflects a broader shift in military logistics planning. Defense leaders have warned that future conflicts may challenge access to established transportation networks, creating demand for flexible and autonomous alternatives.

During a recent test flight, DropShip released multiple 200-pound payloads from an altitude of 300 feet. The cargo landed within roughly 50 feet of the intended target area, according to the company.

Built for denied environments

DropShip was designed as a heavy-lift autonomous platform capable of operating where conventional logistics networks cannot. The hybrid-powered aircraft has a maximum takeoff weight of 1,600 pounds and can carry up to 650 pounds of usable payload. It requires only 550 feet of runway to launch with a full payload.

Pyka says the aircraft can support same-day delivery missions across a 2,000-mile operational radius. It offers a ferry range of up to 3,500 miles and can travel more than 1,000 miles while transporting 500 pounds of cargo. The aircraft cruises at 75 knots and can sprint at 90 knots. It can also operate at service ceilings of up to 20,000 feet mean sea level.

Rapid development pace

The precision airdrop test represents another milestone in what has been a compressed development schedule. Pyka said DropShip completed its maiden flight just six months after the program launched. The aircraft progressed from first flight to autonomous precision airdrop capability within eight months.

The company credited that pace to the core technology stack already powering its commercial aircraft. Engineers adapted existing autonomous systems to speed development and testing.

Expanding mission options

Pyka believes the aircraft could play a role in a variety of missions beyond cargo transport. “Until now, there hasn’t been a safe, economical, or practical way to autonomously deliver critical supplies directly to a specific location hundreds or even thousands of miles away,” Michael Norcia, Pyka’s CEO and co-founder, said.

Norcia said operators could use the aircraft to transport fuel, water, medical supplies, repair parts, and other mission-essential cargo exactly where it is needed. He added that the capability could change logistics operations in remote regions, disaster zones, and contested environments where access remains limited.

Beyond cargo delivery, DropShip can support intelligence, surveillance, and reconnaissance missions, communications support, and expeditionary power applications. The aircraft also features a reconfigurable mission computer designed to accommodate evolving operational needs.

Pyka plans to continue expanding the aircraft’s flight envelope ahead of customer evaluations and operational exercises with the U.S. government later this year.

US President Donald Trump said Thursday that he has canceled planned military strikes against Iran, claiming that negotiations between Washington and Tehran have reached a stage where a broader agreement is close to being finalized.

The announcement marked a dramatic shift after days of escalating tensions that saw both countries exchange strikes and threats, raising fears of a wider conflict in the Middle East.

In a post on Truth Social, Trump said discussions had advanced significantly and received backing from multiple countries involved in the negotiations.

“Based on the fact that discussions with the Islamic Republic of Iran have been brought to the highest level of Iranian leadership and approved, I have, as President of the United States of America, cancelled the scheduled strikes and bombings against Iran this evening,” Trump wrote.

He also claimed that the final elements of the agreement had been approved by several regional and international stakeholders, including Israel, Saudi Arabia, the UAE, Qatar, Turkey, Pakistan, Bahrain, Kuwait, Jordan and Egypt.

From threats to talks

The decision came just hours after Trump issued fresh warnings against Tehran, threatening to hit Iran “very hard tonight” and suggesting the United States could take “total control” of Iran’s oil and gas markets, including the strategic Kharg Island export hub.

Despite calling off the strikes, Trump said US pressure on Iran would continue until a formal agreement is signed.

“The Naval Blockade will remain in full force and effect until this Transaction is finalized – Time and place of the signing to be announced shortly,” he wrote.

The Strait of Hormuz remains one of the world’s most important energy chokepoints, with a significant portion of global oil shipments passing through the waterway. Any disruption there has the potential to impact international energy markets and shipping routes.

Trump later told reporters that a signing ceremony could take place in Europe as early as this weekend. According to reports, Vice President J.D. Vance is expected to attend on behalf of the United States.

Hormuz remains under watch

“The strait (of Hormuz) will officially open as soon as we sign, which could be soon — very soon, maybe over the weekend in Europe,” Trump said. “I won’t be able to be there, but JD will be there.”

Iran has not officially confirmed Trump’s claims that a peace deal is imminent.

However, reports indicate that Qatari officials recently visited Tehran to discuss possible pathways toward a broader agreement aimed at reducing tensions between the two countries.

Trump has for months signaled that a breakthrough with Iran was near. The latest claims come after a week of tit-for-tat strikes that strained an already fragile ceasefire reached in April.

Meanwhile, Iran’s parliamentary speaker Mohammad Bagher Ghalibaf warned that further escalation could have long-term consequences for global energy markets.

He said that “wrong strategies and impulsive decisions” could destabilize energy supplies and “create an endless quagmire that you will be stuck in for years.”

German weapon manufacturer Diehl Defence has developed a jet-powered interceptor drone called the Cobra 600, designed to carry and fire the IRIS-T short-range air-to-air missile against aerial threats including unmanned systems, cruise missiles, and low-altitude manned aircraft.

The system represents a specific response to the growing volume and diversity of airborne threats that conventional ground-based and crewed interceptors may struggle to address cost-effectively at scale.

Airframe and propulsion

The Cobra 600 is a purpose-built unmanned aerial vehicle powered by a small jet engine, giving it the speed and altitude performance needed to pursue fast-moving aerial targets. Its designation references a 600-kilogram class platform, placing it in a weight range that can accommodate meaningful payload capacity while remaining operationally agile.

The jet propulsion distinguishes it from propeller-driven loitering munitions, providing the kinetic energy necessary to reach and intercept time-sensitive targets before they close on defended assets.

The airframe integrates a single IRIS-T missile — a German-developed, infrared-guided weapon with all-aspect engagement capability and a range of several kilometers. The IRIS-T was originally designed for crewed fighter aircraft, so adapting it for autonomous drone carriage required engineering the release and guidance interfaces into a platform without a human pilot onboard.

Autonomous engagement and fire control

One of the more technically demanding aspects of the Cobra 600 concept is the fire control architecture. The drone must receive targeting data, prosecute an intercept geometry, and release the missile — either under remote operator authorization or through a higher degree of autonomous decision-making.

The precise rules of engagement and human-machine teaming protocols for such a system carry legal and ethical weight under international humanitarian law, particularly regarding the degree of human control over lethal force decisions.

The system is intended to operate within a broader integrated air defense network, receiving cueing from ground-based radars or other sensors rather than relying solely on its own onboard detection capability.

This makes the quality of the data link and network integration central to its operational effectiveness — a vulnerability if those links are jammed or spoofed by an adversary using electronic warfare.

Countering drone swarms and low-cost threats

The tactical logic behind fielding an armed interceptor drone, rather than using expensive surface-to-air missiles or diverting crewed fighters, is economic and capacity-driven.

Drone swarms and low-cost one-way attack munitions have repeatedly strained conventional air defense inventories in recent conflicts. A relatively lower-cost interceptor that can be produced and expended at volume offers a more sustainable exchange ratio against cheap threats.

That said, the Cobra 600 itself carries an IRIS-T — a missile that is not inexpensive. The cost calculus improves only if the drone airframe is significantly cheaper than a crewed interceptor sortie, or if it can successfully engage threats that would otherwise require multiple surface-to-air missile shots.

Pairing an IRIS-T with an unmanned platform also raises questions about what happens when the drone misses or the missile fails to guide — issues well understood in crewed aviation but more complex when remote human oversight is limited.

Development status and German defense context

The Cobra 600 emerges at a time when Germany is under sustained pressure to rebuild and modernize its defense industrial base following years of underinvestment. The country is a co-developer and major operator of the IRIS-T missile family, making it a logical choice for domestic integration.

According to reporting by The War Zone, the Cobra 600 concept has been publicly presented as part of Germany’s broader push to field layered air defense solutions capable of handling the evolving threat spectrum seen in contemporary conflicts.

A recently released photograph offers a clear view of the construction of the future USS District of Columbia (SSBN-826), the first of the U.S. Navy’s new Columbia-class ballistic missile submarines. Shared online by Ashley Cowen, Lead Photographer at Newport News Shipbuilding, the image shows major parts of the submarine as work continues toward its planned delivery in 2029.

The photo shows both the bow and the stern sections under construction. These are key parts of the submarine and show that work on the Navy’s top-priority strategic deterrence program is making steady progress.

Key submarine sections take shape

The new image shows clear progress on the bow and stern sections of the submarine. The stern will later house the propulsion system and the unique X-shaped control surfaces, designed to help the submarine move and perform better underwater.

The sections seem to be inside General Dynamics Electric Boat’s South Yard Assembly Building or another large facility at the main shipyard in Groton, Connecticut.

The image arrives months after the arrival of the massive “Atlas” dry dock, which reached the shipyard in January 2026. This dry dock was built to support the construction, maintenance, and future servicing of Columbia-class submarines.

Ongoing deliveries of major submarine parts, hull sections, and support equipment indicate the program is on schedule as builders work to complete the first submarine in the class.

Designed to replace the Ohio-class fleet

The Columbia-class submarines are being built to replace the older Ohio-class ballistic missile submarines, which started service in the early 1980s. As the Ohio-class submarines retire through the early 2040s, the Columbia-class will take over the sea-based part of America’s nuclear deterrent.

Design work for the USS District of Columbia started in 2007, after the U.S. Navy partnered with General Dynamics Electric Boat to create a new class to follow the Ohio-class fleet.

The Navy describes the Columbia-class as being designed to survive better, be available for operations more often, and last longer than the previous class. These submarines are expected to stay in service until at least the 2080s.

This program is seen as one of the most important defense upgrades happening in the United States, since ballistic missile submarines are the most secure part of the country’s nuclear defense system.

Advanced technologies and larger design

The Columbia-class brings several big improvements over the Ohio-class submarines. These include quieter engines, better sonar, upgraded sensors, and new electronic controls for steering the submarine.

These submarines will also be larger than the Ohio-class submarines. When finished, each Columbia-class submarine will weigh more than 20,000 tons.

Even though the new submarines are larger, they will carry fewer missiles—16 UGM-133 Trident II D5 Life Extension submarine-launched ballistic missiles instead of the 24 Trident missiles on the Ohio-class. This change aligns with new strategic needs while maintaining a strong nuclear deterrent.

Each submarine will have four missile compartments, each holding four ballistic missiles.

Massive industrial effort supports construction

The Columbia-class submarines are built using a modular approach. Different contractors build large sections separately, and then these parts are put together at Electric Boat’s Groton facility.

Work is currently underway at Quonset Point, Rhode Island, with help from over 3,000 suppliers across the country. Newport News Shipbuilding makes the main bow and stern parts before they are sent to be added to the final hull.

The Navy plans to build a total of 12 Columbia-class submarines. Boats four through eight will be procured at a rate of one submarine per year over the next five years, with the program costing about $62 billion.

According to current plans, the USS District of Columbia will enter service in 2029, and the last submarine in the class should join the fleet around 2041 or 2042. Together, these submarines are expected to provide America’s sea-based nuclear deterrent for many years.

A new type of counter-drone system is set to enhance the defense of the U.S. Army. L3Harris Technologies has received an order to deliver VAMPIRE counter-unmanned systems (c-UxS) to the U.S. Army to support urgent defense against hostile drones.

The VAMPIRE capability delivers advanced reconnaissance and precision strike against drones and remotely piloted aircraft. Military forces have used the technology extensively in support of European combat operations, logging more than 350,000 operational hours since 2023.

Counter-drone systems can be quickly assembled

“We’ve worked with the Army to understand their needs for new counter-UxS systems that can be quickly assembled, delivered, set up and fired,” said Tom Kirkland, President, Targeting & Sensor Systems, Communications & Spectrum Dominance, L3Harris.

“VAMPIRE is effective at hunting and engaging drone threats affordably, which enables U.S. armed forces to sustain reliable defense of its personnel and infrastructure.”

L3Harris developed and invested in VAMPIRE at the beginning of the war in Ukraine to provide a low-cost solution to eliminate Russian drone threats. The company has maintained that the VAMPIRE is an affordable, compact ISR and counter-unmanned-weapon system designed to deploy on nearly any platform, vehicle, or vessel. 

This all-in-one system excels in Counter-small Unmanned Airborne System (C-sUAS) operations, delivering precision strike capabilities with customizable sensors and weapons, significantly reducing the cost-per-effect and overall cost of ownership.

High-volume production of VAMPIRE systems

The Army’s order is worth up to $106 million as part of the United States’ layered c-UxS defense approach.

In March, the company initiated high-volume production of VAMPIRE counter-unmanned systems (C-UxS) in Huntsville, Alabama. The new production line was a direct response to the United States and its allies’ need to combat the persistent drone threat posing risks to military personnel and infrastructure.

The facility features a flexible assembly, testing, and installation area to integrate VAMPIRE onto ground vehicles and containerized weapon systems. The production line can adjust and increase volume as demand evolves.

Building upon the success of the baseline VAMPIRE system, L3Harris has incorporated additional sensor capabilities, precision weapons, electronic jammers, and non-kinetic effectors for use across several domains. The system uses artificial intelligence and machine learning to more swiftly detect, engage, and defeat small, elusive unmanned threats.

The expanded VAMPIRE family of systems now includes multiple specialized variants.

As drone warfare continues to reshape the battlefield, military planners worldwide are prioritizing layered air-defense networks capable of addressing threats ranging from small commercial drones to more advanced unmanned systems. The U.S. Army’s latest investment in VAMPIRE highlights the increasing role of adaptable, rapidly deployable counter-drone technologies in future defense operations.

With production ramping up and operational demand increasing, the VAMPIRE program represents a significant step in strengthening U.S. and allied defenses against one of the fastest-growing challenges in modern military operations.

Boeing has unveiled a new version of its MQ-28 Ghost Bat drone, which offers extended combat capabilities. The new version has been showcased at the ILA Berlin Air Show in Germany.

The MQ-28 Ghost Bat is an uncrewed collaborative combat aircraft that uses smart human-machine technology to act as a force multiplier for the crewed jets. In December 2025, Boeing and the Royal Australian Air Force (RAAF) made headlines by executing a force-integrated air-to-air autonomous weapon engagement from an MQ-28 Collaborative Combat Aircraft.

The mission involved the Ghost Bat teaming with a RAAF E-7A Wedgetail and F/A-18F Super Hornet to destroy a fighter-class target drone. It was the first time an autonomous aircraft completed an air-to-air engagement with an AIM-20 missile.

The feat had established the Ghost Bat as a “mature combat capable CCA.”

Added capabilities of Boeing MQ-28 Ghost Bat Block 3

The new Block 3 Ghost Bat drone from Boeing features an increased wingspan, allowing it to carry an additional 2,000 pounds of fuel, stores, and mission payloads. Moreover, the drone can now also carry two AMRAAM missiles or four small-diameter bombs (SDBs) internally, and there is also an option to carry three external weapon stations if needed.

It also has beyond-line-of-sight (BLOS) communication links, which will enable the drone to be operated from a crewed aircraft, a ground station, or a naval vessel over nearly unlimited distances. The new design features an upgraded modular, missionized nose that provides enhanced payload configuration options and supports the insertion of third-party capabilities.

The drone now has a maximum take-off weight of 12,000 lbs, up from the 10,000 lbs in version two. It can now carry a useful load of over 4,500 lbs. It also receives significant software upgrades, enabling operators to tailor weapons, payloads, command and control, and mission autonomy to suit their operational requirements.  

“That additional capacity gives operators freedom to balance payload and endurance to configure for the mission at hand, whether that means carrying extra fuel for longer-range operations, increasing weapons carriage, or any combination of both,” said Glen Ferguson, MQ-28 global program director.

Upgrades to be rolled out to the entire fleet

Boeing says the upgrades visible in the third iteration will be rolled out to the entire fleet through a spiral upgrade program. Ferguson added that the inclusion of BLOS and other features has occurred because the company has been working with Air Force units to understand their needs and the role the CCA is intended to play in a joint force operation.

It is not clear whether the turbofan engine used in earlier versions of Ghost Bat is being replaced or another engine is being added to the drone for the extra thrust.

The earlier versions of the CCA had a length of 38 feet (11.7 meters) and a height of 6.5 feet (2 meters). It had a top speed of Mach 0.9 and could fly up to 2,000 nautical miles, with a ceiling of 40,000 feet.

According to reports, the Block 3 Ghost Bat will be offered to Germany. Australia has already acquired a number of Block 1 MQ-28 drones.

At the Berlin Air Show, Boeing also welcomed two additional industry partners to expand its German MQ-28 Ghost Bat industry team. These two – namely Diehl Defense and Rohde & Schwarz – will join Rheinmetall in the program led by Boeing Defense Australia.

Longtime Slashdot reader MattSparkes shares a report from NewScientist, captioned: "For years we've had unconfirmed reports, rumors, hints... now we know." From the report: Fully autonomous drones with no human oversight have killed soldiers on the battlefield for the first time. This is according to a senior figure in the Ukrainian defense industry, marking a watershed moment in warfare. The one-off test involved 10 AI-controlled "Terminator" drones on the front line of the Ukraine war. Russian soldiers were killed. "We tried it," says drone-maker Alexander Kokhanovskyy, who supplied the technology and spoke to New Scientist at a press event hosted by the Ukrainian embassy. "It's a test. We never implemented it [more widely]." The test took place two years ago and involved quadcopter drones that were programmed to fly towards the front line, cover between 3 and 5 kilometres over around 10 minutes and then engage "Terminator mode," in which an AI model searches for and intercepts targets. "We just launch it and we know everything will be dead -- everything that will be found there in this particular area will be dead," says Kokhanovskyy. "There is no connection to the drone at all, you cannot see the video, nothing... Everything it sees will be killed." With no way to tell what the automated drones had seen or targeted, human-piloted drones were sent into the area after the test to manually check results. Victims included "a couple of soldiers, one truck," says Kokhanovskyy. While there is no recording of the automated drones attacking these targets, it was concluded that the drones had killed them. Kokhanovskyy says that he was not at the test personally but that it was carried out by an unnamed military unit near the cities of Bakhmut and Chasiv Yar as part of a Ukrainian counteroffensive push. The Ukrainian Ministry of Defence did not respond to questions about the test or the current legal position on the use of fully autonomous weapons.

Taiwan has conducted its first live-fire exercise using the U.S.-made M142 High Mobility Artillery Rocket System (HIMARS), sending a clear signal of its evolving defense strategy amid growing tensions with China. The drills, which took place on Taiwan’s southwest coast, showcased how mobile precision fires could counter a potential amphibious assault by Chinese forces.

HIMARS: A new edge for Taiwan’s defense

The live-fire demonstration is part of Taiwan’s ongoing efforts to modernize its military and bolster deterrence capabilities. The HIMARS system, known for its mobility and rapid deployment, allows Taiwan to target enemy landing forces and logistical hubs from a safe distance.

During the drills, Taiwanese forces simulated strikes against mock enemy positions, demonstrating their ability to rapidly move, fire, and relocate—minimizing vulnerability to counterattacks.

According to military analysts, HIMARS’ precision-guided munitions offer a significant upgrade over traditional artillery. The system’s ability to deliver accurate strikes up to 300 kilometers (approx 186 miles) away could hold China’s amphibious ships and staging areas at risk, complicating invasion plans.

A strong message to Beijing

The timing of the exercise underscores Taiwan’s determination to resist Beijing’s coercion, which continues to assert its claim over the island. The People’s Liberation Army (PLA) has ramped up military activities near Taiwan in recent years, including amphibious landing drills and air incursions.

Taiwanese officials emphasized that the HIMARS drills were not only a test of new equipment but also a show of readiness. “This exercise demonstrates our commitment to defending our homeland and deterring aggression,” a defense spokesperson stated.

U.S.-Taiwan security cooperation

Taiwan’s acquisition of the HIMARS system is part of a broader arms deal with the United States, approved in 2020. The deal, valued at over $1.8 billion, includes 11 launchers and hundreds of Guided Multiple Launch Rocket System (GMLRS) rockets.The U.S. continues to support Taiwan’s self-defense through arms sales and training, reinforcing its unofficial security partnership.

The HIMARS’ performance in Ukraine has also drawn attention, with Ukrainian forces using the system to disrupt Russian logistics and command centers. Taiwanese officials believe similar tactics could be effective in repelling a Chinese invasion, leveraging mobility and precision to offset China’s superior numbers.

Challenges and future developments

Despite the advantages, military experts caution that HIMARS alone cannot guarantee Taiwan’s security. Effective use depends on robust intelligence, coordination, and the ability to survive against China’s advanced missile and drone capabilities. Taiwan is therefore investing in improved command-and-control networks, camouflage techniques, and rapid resupply methods.

Looking ahead, Taiwan plans to integrate HIMARS with other defensive assets, such as coastal missile batteries and unmanned aerial vehicles, to create a multi-layered shield against amphibious assaults. The recent drills mark a significant step in adapting modern warfare technologies to Taiwan’s unique security needs.

As cross-strait tensions persist, Taiwan’s demonstration of HIMARS capability serves as both a deterrent and a message of resilience, signaling its resolve to defend its sovereignty against growing military pressure from China.

A German company has showcased its next-generation highly mobile air defense system. Called IRIS-T SLS MK4, the system is specifically designed to protect troops on the move and critical infrastructure from airborne threats.

Developed by Diehl Defence, this fourth generation of the IRIS-T SLS system has an effective range of 7 miles (12 km) and an altitude coverage of up to 3.7 miles (6 km).

The company revealed that the system combines the components radar, C2 system and launcher, including effectors, on one vehicle, making it an “all-in-one” solution. Due to its high mobility and a compact design, the air defense system can be relocated in a very short time.

High degree of automation

Further key features of IRIS-T SLS MK4 are the high degree of automation and the resulting low manpower requirements, which enables extremely fast response times. The vehicle-independent design allows maximum flexibility for different customer demands, according to a press release.

Diehl Defence also revealed that the proven IRIS-T air-to-air missile is used as effector. It remains unchanged in hardware and will enable the “fire-on-the-move” capability in the future – the firing of the missile on the move. The integration of additional effectors, such as the C-UAV eMissile CICADA from Diehl Defence or a weapon station, is also possible.

MK4 version consistently meets NATO standards

The SLS system is already fully integrated into the Diehl Defence concept of multi-layered air defense. The further development and upgrade to the MK4 version consistently meets NATO standards and operational requirements, including an increased payload capacity with an eightfold load and the associated increase in combat effectiveness.

The IRIS-T missile is and remains the core element of ground-based air defense at Diehl Defence, even in the combat-proven SLS system. As an air defense system with future-proof capabilities, IRIS-T SLS MK4 stands for high performance in dynamic threat scenarios.

Another important aspect of the new system is its modularity. The vehicle-independent design allows integration onto different platforms to meet customer requirements. Diehl Defence also stated that additional effectors, including its CICADA counter-unmanned aerial vehicle interceptor and remote weapon stations, can be incorporated into the system, expanding its mission profile beyond conventional air defense.

The unveiling of the IRIS-T SLS Mk4 comes at a time when demand for modern ground-based air defense systems is rising sharply across Europe and other regions. The success of the broader IRIS-T family in operational deployments and growing investment in layered air defense networks have positioned the system as a key component of future NATO and partner-nation air defense architectures.

With its combination of mobility, automation, modularity, and proven missile technology, the IRIS-T SLS Mk4 represents Diehl Defence’s latest effort to provide armed forces with a flexible and rapidly deployable solution for countering evolving aerial threats in an increasingly complex security environment.

Researchers in the United States are studying impact flashes generated by high-speed collisions. It’s being claimed that advances in understanding the optical impact flashes can be highly beneficial for missile defense, making it possible to determine the composition of an intercepted missile and its payload.

Conducted by researchers in Southwest Research Institute (SwRI), the work could also aid scientists in identifying the origins of meteorites or asteroids impacting surfaces, based on their composition.

Energy of the impact creates a flash

“When a meteorite strikes the surface of a moon or planet, the energy of the impact creates a flash that gives off so much energy that the chemical signatures of its constituent materials are visible at different wavelengths,” said Dr. Pablo Bueno, a lead engineer in SwRI’s Mechanical Engineering Division.

Researchers have revealed that the impact flash is a physical phenomenon resulting from conventional and hypervelocity impact. The emission of the flash is related to the composition of the target; thus, spectrographic measurements provide spectral data that could be used to identify the materials involved in the collision, according to the project.

Bueno and Roberto Enriquez-Vargas, an SwRI senior research engineer, recently completed an internally funded SwRI project that developed and refined methods for using high-speed spectroscopy to analyze the light emitted during hypervelocity impacts, where the impact flashes typically only last a few microseconds. The short time window required capturing spectral data quickly and precisely, according to a press release.

Laser-based triggering system

Bueno and Enriquez-Vargas used both of SwRI’s two-stage light-gas guns to create hypervelocity impacts representative of missile strikes or asteroid impacts. The large gun system generates velocities up to 7 kilometers per second (15,660 mph). The system is 22 meters (72 feet) long and traditionally used to study ballistics, as per the release.

Because the impact occurs so swiftly and the flash decays rapidly, Bueno and Enriquez-Vargas developed a laser-based triggering system to precisely detect the instant an impact occurs, accurately measuring impact timing within 100 nanoseconds, or one 10-millionth of a second, according to researchers.

“Thicker targets produced brighter, longer flashes,” Bueno explained. “Higher atmospheric pressure created broader and thicker emission lines in the spectra, and in many cases materials at high temperature behaved differently than they did when impacted at room temperature.”

The team developed and tested laser-based triggering scheme. Accurate timing within 100 ns of the impact was demonstrated.

The team also revealed that the strong lines of the emission spectra of aluminum and copper have been measured and characterized within ±2 nm of their published values. The doublet near 396 nm, for aluminum, and the triple near 515 nm, for copper, have been selected as the best lines to continue with the experimental test matrix.

The effects of projectile flight speed, atmospheric pressure, and atmospheric composition have been documented. These results are fulfilled in part metric 3 of the program. The results show these parameters affect the amplitude and width of the emission lines, according to the project.

Kratos Defense & Security Solutions is ramping up manufacturing capacity for its Spartan family of small gas turbine engines, responding to increased procurement activity across missile programs and loitering munition platforms.

The company confirmed the production expansion through an official press release.

What the Spartan engine is and why it matters now

The Spartan family comprises of compact turbojet engines designed specifically for expendable and attritable platforms — systems built to be used once or with minimal recovery expectation. These engines sit in a performance envelope suited to subsonic cruise missiles, decoy drones, and one-way attack munitions, where cost-per-unit and production throughput matter as much as raw performance.

Steve Fendley, President of Kratos Unmanned Systems Division said “As the Department of War focuses on rebuilding critical missile inventories and increasing affordable precision-strike capacity, the need for scalable, high-performance but low-cost propulsion systems has never been greater.”

He further said “Kratos is investing today to ensure our customers have access to affordable, reliable, American-made propulsion systems that can be delivered at the speed and scale required by the modern threat environment.”

Loitering munitions, sometimes referred to as kamikaze drones, have moved from niche battlefield tools to standard procurement items for multiple NATO and allied militaries following their documented use in conflicts in Ukraine and the Middle East. That shift has created a supply pressure on propulsion systems, which have historically been a bottleneck in scaling expendable platform production.

Production expansion details

Kratos states that it will produce 3000 engines in 2027. The Spartan line covers multiple thrust classes (ranging from 30 lb to 200 lb at sea level), allowing a single manufacturing infrastructure to serve different platform weight categories without requiring entirely separate production lines.

The vertical integration Kratos maintains over its propulsion systems — designing and building engines in-house — gives the company tighter control over delivery schedules, a factor that has become a competitive differentiator as defense primes face long lead times on subcomponents.

This investment by the company is strategically aimed at supporting US Department of War`s priorities to replenish missile inventories, expand production capacity for precision-strike weapons, and deliver affordable mass capabilities across the US armed forces

Engineering tradeoffs in expendable propulsion

Designing a gas turbine for an expendable platform involves deliberate compromises. Engineers typically target a service life measured in hours rather than thousands of flight cycles, which allows for reduced material grades in certain hot-section components (cooled by the onboard fuel in Spartan engines) and simplified maintenance architecture.

Supply chain and geopolitical context

Western defense planners have grown increasingly focused on magazine depth — the ability to sustain munitions expenditure over a prolonged conflict — following assessments of consumption rates in Ukraine. Loitering munitions and cruise missiles consume propulsion units at a pace that peacetime production lines were not sized to support. Kratos quotes an annual production capacity of 10,000 Spartan engines probably indicating towards a buffer surge production capability.

According to the company these engines are designed and manufactured in the United States at Oxford, Michigan, with all parts and components sourced from U.S. companies.

As military helicopters face growing threats from small attack drones, Airbus Helicopters and German defense technology firm Quantum Systems are betting that the answer could come from the aircraft themselves. The companies announced a cooperation agreement at the ILA Berlin Air Show to explore equipping Airbus military helicopters with counter-drone interceptors developed by Quantum Systems.

The effort will begin with the H145M, a light multirole helicopter already used by several armed forces around the world. The partnership does not yet involve a production contract or deployment timeline. Instead, it marks an early step toward determining whether helicopters can carry dedicated systems designed to detect and defeat hostile drones before they reach their targets.

Rising drone threat

The battlefield has changed rapidly in recent years. Small unmanned aircraft have evolved from reconnaissance tools into low-cost weapons capable of threatening troops, vehicles, and aircraft.

For helicopters, the danger is especially acute during takeoff, landing, and low-altitude operations. Those flight phases often leave crews with fewer options to evade incoming threats.

Commercial drones modified to carry explosives and purpose-built attack systems have demonstrated how vulnerable traditional platforms can be in contested environments. Existing helicopter self-protection suites were largely designed to counter missiles and conventional aircraft rather than swarms of small drones.

Airbus and Quantum Systems want to close that capability gap.cStefan Thomé, executive vice president of programs at Airbus Helicopters, said the company continues to seek new operational capabilities that deliver practical value to military customers.

He described the agreement as an important move toward expanding what military helicopters can do in increasingly complex airspaces. “The H145M, with its advanced open system architecture and exceptional growth potential, serves as the ideal launching pad for this joint initiative,” Thomé said.

Why the H145M?

The H145M already performs a wide range of missions. Operators use the twin-engine helicopter for special operations support, medical evacuation, reconnaissance, and light attack roles.

Its modular design allows crews to add sensors, weapons, and mission equipment without extensive redesign. Airbus argues that flexibility makes it a natural candidate for testing counter-drone technologies. The helicopter also serves several NATO members and export customers across multiple regions, giving any future capability broader relevance.

Europe’s defense experiment

Quantum Systems built its reputation through reconnaissance drones, particularly its Vector fixed-wing platform. Several European militaries have evaluated the system, and Ukrainian forces have used it operationally. Counter-UAS technology represents a newer area of focus for the Munich-based company.

Martin Karkour, Quantum Systems’ chief revenue officer, said the partnership highlights how European defense companies can combine specialized expertise to address emerging threats. “Current developments show that aerial systems need answers to drone threats,” Karkour said.

Airbus also used ILA Berlin to showcase the U145, an uncrewed version of the H145 family. A mockup on display featured Quantum Systems’ counter-drone capability. Many questions remain unanswered. The companies have not disclosed technical details, testing schedules, or qualification plans.

Still, the initiative reflects a broader shift in military aviation. As inexpensive drones reshape modern warfare, aircraft manufacturers are increasingly searching for ways to ensure crewed platforms can survive in skies crowded with uncrewed threats.
