Quick Summary

Pete Hegseth, US secretary of defense, signed a memo last month allowing the Department of Homeland Security (DHS) to test the Active Denial System, a non-lethal weapon that emits an intense heat beam causing people to move away reflexively, for seven months at the US-Mexico border. The DHS can request further use if needed and plans to evaluate its effectiveness in enhancing security while saving lives, though specific uses remain unclear. The system has been considered before but never deployed; it produces a 95 gigahertz beam penetrating about 1/64th of an inch into the skin, creating discomfort that lasts around 10-15 minutes.

Story summary

Pete Hegseth, the US secretary of defense, reportedly signed a memo in September 2026 allowing the Department of Homeland Security (DHS) to test a non-lethal "heat ray" known as the Active Denial System at the US-Mexico border. This weapon uses an energy beam that causes intense heat on skin, leading people to instinctively move away from it. The DHS will have access to the Pentagon's system for seven months and can extend its use if needed.

A spokesperson for Customs and Border Protection (CBP) stated that they are evaluating new technology aimed at saving lives while enhancing national security. However, details about how the Active Denial System will be used remain unclear. When contacted by CNN, the Pentagon referred questions to the DHS, which provided the CBP statement.
