It’s Now Possible To Telepathically Communicate with a Drone Swarm
BY PATRICK TUCKER
DARPA's new research in brain-computer interfaces is allowing a pilot to control multiple simulated aircraft at once.
A person with a brain chip can now pilot a swarm of drones — or even advanced fighter jets, thanks to research funded by the U.S. military's Defense Advanced Research Projects Agency, or DARPA.
The work builds on research from 2015, which allowed a paralyzed woman to steer a virtual F-35 Joint Strike Fighter with only a small, surgically-implantable microchip. On Thursday, agency officials announced that they had scaled up the technology to allow a user to steer multiple jets at once.
“As of today, signals from the brain can be used to command and control ... not just one aircraft but three simultaneous types of aircraft,” said Justin Sanchez, who directs DARPA's biological technology office, at the Agency's 60th-anniversary event in Maryland.
More importantly, DARPA was able to improve the interaction between pilot and the simulated jet to allow the operator, a paralyzed man named Nathan, to not just send but receive signals from the craft.
“The signals from those aircraft can be delivered directly back to the brain so that the brain of that user [or pilot] can also perceive the environment,” said Sanchez. “It's taken a number of years to try and figure this out.”
In essence, it's the difference between having a brain joystick and having a real telepathic conversation with multiple jets or drones about what's going on, what threats might be flying over the horizon, and what to do about them. “We've scaled it to three [aircraft], and have full sensory [signals] coming back. So you can have those other planes out in the environment and then be detecting something and send that signal back into the brain,” said Sanchez.
The experiment occured a “handful of months ago,” he said.
It's another breakthrough in the rapidly advancing field of brain-computer interfaces, or BCIs, for a variety of purposes. The military has been leading interesting research in the field since at least 2007,. And in 2012, DARPA issued a $4 million grant to build a non-invasive “synthetic telepathy” interface by placing sensors close to the brain's motor centers to pick up electrical signals — non-invasively, over the skin.
But the science has advanced rapidly in recent years, allowing for breakthroughs in brain-based communication, control of prosthetic limbs, and even memory repair.

USAF Picks B-21 For Software Learning Demo Challenge
By Steve Trimble The U.S. Air Force has selected the Northrop Grumman B-21 to demonstrate a potentially revolutionary approach to flightworthy software. The future stealth bomber will demonstrate a software architecture running the operational flight program (OFP) that learns and adapts as it flies a mission, says Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics. Such an approach potentially “allows them to land with better code than they took off with,” Roper tells Aerospace DAILY. The architecture enables the code to update itself during a mission. Asked if the demonstration involves software code in the OFP, the operating system of a military aircraft, Roper replied affirmatively: “Within the OFP. That kind of adaptability is what we want to aspire to.” As a special access program, details of the B-21's schedule, capabilities and even cost are kept secret. But Roper says he is able to discuss what he calls the “digital bullet challenge,” albeit within strict limits. Asked if the B-21 software demonstrations imply the insertion of a deep learning technique known as a neural network, Roper declined to answer. “Details of how I won't go into,” Roper says. “But B-21 is trying to not just do agile software. They want to blaze new territory, a new trail for the Air Force. The idea that one of our most complicated airplanes with one of the most challenging missions is also taking on one of the most challenging software approaches to make their software living [and] breathing on the plane itself is inspiring. “They're going to be pushing the boundaries of how aircraft software should work in this century, and increasingly the software is where the cutting edge—the winning edge—is going to come from,” he explained. Roper's description appears to push the boundaries of software used in the flight computers of a commercial or military aircraft. Aircraft certification standards demand a highly rigid approach to software architecture, with the function of each line of code validated and verified on the ground before it is allowed to be used in flight. The challenge set for the B-21 could lead to altering or even adding software lines of code in the OFP during a flight. The Air Force launched the B-21 program in 2015 by awarding a $21.4 billion contract to Northrop. Air Force officials have previously announced that first flight is scheduled around December 2021. The aircraft will take off from Northrop's final assembly center in Palmdale, California, and fly to the flight test center on the adjoining Edwards Air Force Base. https://aviationweek.com/defense/usaf-picks-b-21-software-learning-demo-challenge

Boeing begins involuntary layoffs, but defense biz to remain mostly untouched
By: Valerie Insinna WASHINGTON — Boeing began making its first round of involuntary layoffs on Wednesday morning, announcing that it will slash the jobs of approximately 6,770 employees across the United States. Boeing's massive commercial business will take the brunt of the cuts, with the company's defense, space and security division only expected to shed less than 100 employees through involuntary layoffs this week. “While the deeper reductions are in areas that are most exposed to the condition of our commercial customers, the ongoing stability of our defense, space and related services businesses will help us limit overall impact, and we will continue hiring talent to support critical programs and meet our customers' evolving needs,” a Boeing spokesman said in a statement. Boeing plans to reduce its total headcount by 10 percent through natural turnover, voluntary layoffs and involuntary cuts — a measure made necessary by the ongoing impact of the COVID-19 pandemic, which has shook the travel industry and called into question commercial airlines' ability to pay for Boeing aircraft already on order. So far, about 5,520 U.S.-based employees have been approved for voluntary layoffs, with about 380 of that sum coming from Boeing's defense business. The approximately 6,770 U.S.-based employees that will be involuntarily laid off this week represents the largest portion of layoffs expected by the company. Those workers will receive severance pay, COBRA health care coverage and career transition services, Boeing CEO Dave Calhoun said in a message notifying employees about the cuts. “The several thousand remaining layoffs will come in much smaller additional tranches over the next few months,” a Boeing spokesman said. In his message to Boeing employees, Calhoun hinted that the situation is to improve as countries begin reopening businesses and more customers feel comfortable booking air travel. However, it will take years for Boeing to fully recover from the pandemic, he added. “The COVID-19 pandemic's devastating impact on the airline industry means a deep cut in the number of commercial jets and services our customers will need over the next few years, which in turn means fewer jobs on our lines and in our offices. We have done our very best to project the needs of our commercial airline customers over the next several years as they begin their path to recovery,” Calhoun wrote. “I wish there were some other way.” https://www.defensenews.com/industry/2020/05/27/boeing-begins-involuntary-layoffs-but-defense-biz-to-remain-mostly-untouched/
