New navigation satellites in low-Earth orbit could provide 100 times stronger signal strength compared to GPS and other global navigation satellite systems operating from higher orbital altitudes—enabling greater location accuracy within dense cities, under thick foliage, and even inside buildings. Such signals would also likely prove more resilient to interference at a time when commercial flights, maritime shipping, and even various smartphone apps face increasingly widespread disruption from GPS jamming.

That vision may start to take shape when the first six production satellites of California-based Xona Space Systems are scheduled to launch in October 2026, with early service starting in 2027. Once the full constellation of 258 Pulsar satellites has been launched in the following years, Xona claims that customers will be able to accurately pinpoint their locations anywhere on Earth to within several centimeters.

“That added power means that we can get into that indoor environment that GPS can't get to today,” Adrien Perkins, co-founder and VP of engineering at Xona Space Systems, told Ars. “Our higher power allows you to get into those jamming environments a lot further than you would with GPS by itself.”

For the first time in its history, the US military sent explosive-laden drone boats into combat by attacking an Iranian midget submarine and naval port. The unprecedented use of such kamikaze sea drones by the United States comes nearly a decade after Iranian and Houthi forces first demonstrated such weapons.

The US military shared a video showing three “one-way attack surface drones” exploding after approaching an Iranian midget submarine and ship maintenance facility at Iran’s Bandar Abbas Naval Base on the night of July 12. US Central Command, the US military combat command responsible for Middle East operations, described the strikes in a social media post as the “first time American forces have employed sea drones in combat operations.”

The US drone boats were able to “make a low-speed, uncontested approach” to their targets before exploding, according to USNI News, a news service from the nonprofit US Naval Institute. USNI News also identified one of the targets as an Iranian Ghadir-class midget submarine that was out of the water while being suspended from a gantry.

Ukrainian drone strikes have forced Russia to completely halt shipping in the Sea of Azov in less than a week, showing once again how a country without traditional naval power can still effectively blockade maritime corridors.

Ukraine’s Unmanned Systems Forces have flown one-way attack drones to target and strike more than 100 Russian tankers and other ships in total, along with posting video evidence showing such drone strikes occurring every night between July 6 and July 14. The campaign has forced Russia to completely shut down the shipping route that flows from Russia’s Don River into the Sea of Azov, and to halt all Kerch Strait shipping transits from the Sea of Azov into the Black Sea, according to Reuters reporting.

The shutdown of such maritime lanes has further isolated the Russian-occupied Crimean Peninsula by cutting off seaborne delivery of fuel in particular. Crimea had already been experiencing severe fuel rationing and power outages as Ukraine stepped up its mid- and long-range drone strike campaign on Russian energy infrastructure and supply lines, leaving behind damaged oil refineries with billowing black smoke and burned-out trucks littering highways.

More cities and towns deployed drones to spot illegal fireworks during the Fourth of July celebrations commemorating America’s 250th anniversary—leading to a $100,000 fine in one instance and coming as part of a broader national trend of first responders turning to drone surveillance.

Police and fire departments have described using both increased drone surveillance and steep fines to deter people from shooting off illegal fireworks, with many departments publicizing their drone videos on social media and warning that their drones will be watching in the future. Incidents involving illegal fireworks have led to costly fires, injuries, and even multiple deaths each year, along with creating local air and noise pollution for residential neighborhoods.

This year, the $100,000 fine for illegal fireworks came from the Sacramento Fire Department in Northern California deploying its own drones for the first time on the Fourth of July, according to CBS News Sacramento. Sacramento Fire Captain Justin Sylvia described the fire department’s drones as being capable of recording scenes in high-resolution video to help investigators identify the house or closest location using Google Maps.

The US military has lost dozens of Reaper drones collectively worth more than $1 billion while carrying out surveillance and attack missions over Iran. Now the Pentagon is seeking large numbers of cheaper drones that can perform such missions despite the expectation that many will be lost in combat.

In a call for industry pitches, the Defense Innovation Unit’s notice described the US military’s current reliance on drones and crewed aircraft, each costing more than $30 million, as being “unsustainable against adversaries utilizing layered defenses enabled by increasingly low-cost antiaircraft capabilities.” It envisions deploying more “cost-effective” drones to “overwhelm enemy air defenses even while experiencing numerous [drone] losses.”

That is, in practice, what Ukraine’s military has been demonstrating with its long- and mid-range strike campaign against Russian supply lines, oil refineries, and various energy or industrial targets within Russia or occupied Ukraine. The Ukrainian campaign has been overwhelming Russia’s overstretched air defense capabilities by launching hundreds of relatively inexpensive drones and missiles on a daily basis to attack targets far behind the frontlines, while continuing to damage or destroy Russia’s most sophisticated air defense systems.

Mysterious drone flights that disrupted major European airports and flew over NATO member military bases hosting US nuclear weapons may be the work of a coordinated Kremlin campaign launched from Russian-linked commercial ships.

That recent assessment from the UK-based International Institute for Strategic Studies used automatic identification system (AIS) maritime tracking data and other publicly available data to show how Russian-linked ships and “shadow fleet” vessels that transport sanctioned Russian oil were often located nearby during various drone incidents. The report suggests that the drone incidents—which impacted a dozen NATO member countries and Ireland between August 2024 and February 2026—also revealed the vulnerability of European air defenses against surveillance and harassment incursions by low-cost drones.

The IISS report identified 144 drone sightings over Europe during that time period that were unlikely to involve hobbyist recreational drones or drone activity related to the war in Ukraine. About 48 percent of the sightings took place over military bases, 26 percent happened over critical infrastructure such as ports and energy or industrial facilities, and 18 percent occurred over civilian airports. Most occurred at night or in the early morning hours before sunrise, and the drones themselves were typically described in media reports as resembling “professional” or “military-style” drones.

A long-standing ban on commercial supersonic flights over the United States would be overturned in a new rule proposed by the US Federal Aviation Administration. That could pave the way for the possible return of commercial supersonic airliners—as long as such aircraft can reduce the ground-level impacts of their sonic booms.

The FAA originally banned overland supersonic flights by civil aircraft in 1973, following US military tests involving supersonic flights over US cities such as Oklahoma City, Chicago, and St. Louis in the 1960s. But the Trump administration has championed the repeal of the ban to pave the way for supersonic airliners that could operate without disruptive sonic booms. So the FAA’s new rulemaking action on June 30, 2026, follows the direction of an executive order issued by President Trump on June 6, 2025.

The newly proposed rule would replace the 53-year prohibition with an interim “noise-based” certification standard requiring any sonic boom overpressure at the surface to be kept below 0.11 pounds per square foot. That proposed standard is based on the Colorado-based startup Boom Supersonic having demonstrated quiet Mach cutoff flights with its XB-1 aircraft—harnessing specific atmospheric conditions while flying just beyond supersonic speeds at higher altitudes so that the aircraft’s shockwaves are refracted upward into the atmosphere rather than traveling to the ground.

In a supposed “nationwide first” use of drones to disarm a person, the Sacramento County Sheriff’s Office in California promoted a video showing how a small quadcopter drone used a dangling magnet to remove a knife from the hand of a motionless suspect.

The promotional video shared to Facebook and Instagram on June 22, 2026, uses the Mission: Impossible film franchise theme to dramatize video footage of the incident that took place earlier in the month, which involved what the video describes as a “felony suspect armed with a knife and a firearm” who “was not responding to negotiators.” The sheriff’s office is just one among hundreds of US police departments and sheriff’s offices that have deployed camera-equipped drones to assist first responders.

In a Facebook post, the Sacramento County Sheriff’s Office described having surrounded the suspect’s residence with a SWAT team after the “known felon and parolee-at-large was seen earlier with a firearm.” A first drone deployed to the scene located the suspect hiding in a corner of the garage, but also spotted the motionless suspect holding a knife in one outstretched arm.

Dozens of new robot arms have been installed at General Motors’ flagship electric vehicle factory in Detroit—even as 1,300 workers remain out of work following what was supposed to be a temporary layoff. The latest automation push has spurred union pushback over a potentially existential issue for automakers and their workers.

General Motors installed approximately 50 robot arms at GM’s Factory Zero plant in Detroit, Michigan, according to reporting by Crain’s Detroit Business. Made by the Japanese robotics company FANUC, the robots are designed to help attach various components to vehicles during the assembly line process. But leaders at United Auto Workers (UAW), the primary US union for autoworkers, reacted with anger to the new robotic presence, given how GM has not yet called back any of the workers affected by supposedly temporary layoffs in March.

More than 1,000 union members are still “laid off indefinitely,” James Cotton, president of UAW Local 22, told The Detroit News. He said that the company could bring some of those members back to work instead of installing the 50 robots.

Taiwan’s existence as a self-governing democracy may depend heavily on having enough military drones to discourage any attempted invasion by China’s military. As the Taiwanese government aims to boost domestic production of military drones and Taiwanese citizens sign up for drone flight training, Taiwanese companies are forming international partnerships to sell more drones to the US military and other overseas buyers.

Taiwan’s Ministry of National Defense proposed a special budget that would spend $6.6 billion over six years on buying drones made in Taiwan, according to the Central News Agency that represents the national news service of Taiwan. Presented on June 18, the budget proposal would allow the government to buy more than 208,000 coastal attack drones, along with more than 1,400 coastal reconnaissance drones and 1,320 uncrewed surface vessels, between 2026 and 2031.

That would be a significant boost to the Taiwanese military arsenal that currently includes just 5,000 US-made attack drones and domestically produced drones, according to Resilience Media. During military exercises in early June, Taiwanese soldiers fired Altius-600 loitering munition drones—made by a subsidiary of the US military technology company Anduril Industries—from towed flatbed launchers to strike offshore targets, according to USNI News. In another exercise earlier this year, Taiwanese Marines used Taiwan-made drones to similarly strike targets at sea.

What happens when you give AI coding agents a lab full of robotic arms, some compute resources, and a “generous token budget” for teaching the robots various tasks? The agents can apparently figure out a training regimen that teaches the robots to successfully cut zip ties and even insert GPUs into thin sockets on motherboards.

That glimpse into how AI can act in a fully autonomous way to automate robot training was made possible by a new agent harness framework—software that wraps around AI models to enable their use of various tools while also providing capabilities such as memory, context, constraint, and feedback loops. That agentic harness, called ENPIRE, was developed by robotics researchers at the Nvidia GEAR (Generalist Embodied Agent Research) lab alongside collaborators from Carnegie Mellon University in Pittsburgh and the University of California, Berkeley.

“A part of our NVIDIA GEAR lab now self-improves tirelessly overnight,” wrote Jim Fan, director of AI at NVIDIA, in a LinkedIn post. “We just read the reports in the morning.”

The US Department of Defense has a lot of congressionally mandated homework to do every year involving hundreds of required reports on various national security topics. But Pentagon officials have been proudly describing a new shortcut—using generative AI tools to write such reports for Congress.

Pentagon Chief Technology Officer Emil Michael highlighted AI-generated reports to Congress as a key example of how the Department of Defense—stylized as the Department of War under the Trump administration—has adopted generative AI during an event hosted by the Hudson Institute think tank in Washington, DC, on June 12. The Pentagon has made AI tools, starting with Google Cloud’s Gemini for Government, widely available to members of all six military branches through the department’s bespoke GenAI.mil platform since December 2025.

“I have to report to Congress every year on this thing,” Michael said. “Let me load all the papers onto it and have it draft me a congressional report that would otherwise take 200 hours of staffing time and do it in five hours.”

A US Army helicopter gunship was apparently struck by an Iranian Shahed drone before going down near the Strait of Hormuz—but it's unclear whether the one-way attack drone was deliberately aimed or achieved more of a lucky accidental strike.

Axios correspondent Barak Ravid first reported an unnamed US government official’s comments that an Iranian drone had hit the US Army AH-64 Apache helicopter before the latter went down on June 8. The New York Times later confirmed that reporting through more anonymous US officials, including one official who said US military investigators were still evaluating whether the Iranian drone strike on the helicopter was intentional or accidental.

Iran has fired thousands of such Shahed drones against a wide range of military and civilian targets in the Gulf region since February 28, 2026, when the United States and Israel began the war by jointly attacking Iran with a barrage of bombs and missiles. But Shahed drones have mainly struck stationary targets such as Amazon data centers and energy facilities, sometimes hitting slow-moving commercial ships in the Strait of Hormuz.

A drone boat picked up two US Army pilots from waters near the Strait of Hormuz after their helicopter gunship went down, US military officials said. The incident apparently represents the first time the US military has used a drone for such a rescue mission at sea.

The two crew members from the US Army AH-64 Apache were “rescued by American forces” at 7:33 pm US Eastern Time after their helicopter went down off the coast of Oman on June 8, according to a US Central Command press release. That press release mentioned support from US Navy units including the US 5th Fleet’s Task Force 59, which is charged with integrating uncrewed aerial, surface, and underwater vehicles, alongside AI, into 5th Fleet maritime operations.

Anonymous US military officials initially told CBS News that the Apache air crew was rescued by an uncrewed surface drone operated by Task Force 59 from the US Fifth Fleet in Bahrain. The officials also described the incident as the first time the military had used a drone to rescue people from the water.

Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future.

The discovery came from an investigation detailed in a June 2 preprint paper by Todd Humphreys and his student Zach Clements at The University of Texas at Austin, along with Argyris Kriezis at Stanford University in California. By sifting through public data from ground-based stations with global navigation satellite system (GNSS) receivers, they identified a pattern of high-powered interference lasting less than 10 seconds each time but simultaneously detectable by ground stations across Europe from Norway to Spain to Poland, and even reaching as far west as Greenland and Canada.

By analyzing the ground station data from January 2019 to April 2026, the researchers found 75 days with at least one widespread GNSS interference event overlapping with the GPS L1 frequency band centered on 1575.42 megahertz. That represents the main band used for signal transmission by the US-made GPS satellite constellation and GNSS constellations from other countries.

Thousands of electric vehicles in Waymo’s autonomous robotaxi fleet may eventually give up their used batteries for a very different purpose—contributing up to hundreds of megawatt-hours of stationary energy storage to local power grids.

That prospect comes from a “strategic supply agreement” announced by Waymo and B2U Storage Solutions on June 4. B2U has been repurposing thousands of used batteries from various electric vehicles by installing them in large stationary energy storage projects. Such energy storage facilities can capture excess renewable energy during low demand periods and release such energy when local power grids are experiencing peak demand periods.

“Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use,” Freeman Hall, CEO of B2U Storage Solution, told Ars. “Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them.”
