The U.S. Army has completed testing of a laser capable of shooting down suspicious drones.

The laser, which was developed as a component of the Army Directed Energy-Maneuver Short-Range Air Defense (DE M-SHORAD) weapon system, harnesses energy to focus a beam of photons at oncoming suspicious drones.

The system, according to developers, relies on onboard sensors to detect such potentially threatening drones, or unmanned aircraft systems (UASs).

Such drones can lend to air safety issues and could potentially serve as flying weapons.

The laser, which was tested at Oklahoma’s Fort Sill, is expected to be ready for use in 2022.
