Directed Energy Counter-UAS

Directed Energy Counter-UAS systems use focused beams of energy, like high-power lasers or microwaves, to disable or destroy hostile drones. Instead of firing projectiles, they neutralize aerial threats with speed-of-light precision.

TECHNICAL DEFINITION

A Directed Energy Counter-UAS (DE C-UAS) system is a non-kinetic defense technology that employs high-energy lasers (HEL) or high-power microwaves (HPM) to neutralize unmanned aerial system (UAS) threats. This capability offers a scalable, low-cost-per-shot solution for defeating single or swarm drone attacks by disrupting electronics or inducing structural failure.

BACKGROUND

The National Defense Authorization Act for Fiscal Year 2026 is a United States federal law which specifies the budget, expenditures, and policies of the U.S. Department of Defense (DOD) for fiscal year 2026. The NDAA is an annual act of Congress that redefines the U.S. military budget.
