Air Force on Directed Energy Weapon Safety

10.16.08 | 1 min read | Text by Steven Aftergood

A new U.S. Air Force Instruction (pdf) establishes a safety program for directed energy weapons (DEW) in view of the fact that “DEW systems create unique hazards that are different from conventional and nuclear weapons.”

“Potential DEW systems covered by this instruction include, but are not limited to, high-energy lasers, weaponized microwave and millimeter wave beams, explosive-driven electromagnetic pulse devices, acoustic weapons, laser induced plasma channel systems, non-lethal directed energy devices, and atomic-scale and subatomic particle beam weapons.”

See Air Force Instruction 91-401, Directed Energy Weapon Safety, September 29, 2008.

Update: Sharon Weinberger at Danger Room volunteered to be on the receiving end of a directed energy weapon known as the Active Denial System and she lived to tell the tale, and more besides, here.

Federation of American Scientists, Future of Life Institute Present Converging Risks Report, AI Impact Awards at Gala

FAS and FLI partnered to build a series of convenings and reports across the intersections of artificial intelligence (AI) with biosecurity, cybersecurity, nuclear command and control, military integration, and frontier AI governance. This project brought together leaders across these areas and created a space that was rigorous, transpartisan, and solutions-oriented to approach how we should think about how AI is rapidly changing global risks.
