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.

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.”
