Instead of disabling a drone with bullets, it uses radio frequencies.

Firing Back

In June, Iran's military shot down one of the U.S. Navy's $130 million Global Hawk drones, claiming it had veered out of international airspace and into the nation's territory.

Now, the U.S. Navy has returned the favor, using a new directed-energy weapon to disable an Iranian drone in the same region — marking the next-generation device's first known "kill."

Mixed Signals

According to a Department of Defense statement, a fixed wing drone approached the USS Boxer while the ship traveled through the Strait of Hormuz on July 18. The drone then came within a threatening range, prompting the crew to take "defensive action."

A defense official later told on the condition of anonymity that the Navy took out the drone using its Light Marine Air Defense Integrated System (LMADIS), a new device that uses radio frequencies to jam drones.

Iran's Minister of Foreign Affairs Mohammad Javad Zarif, meanwhile, has denied the incident altogether, telling reporters the nation has "no information about losing a drone."

First Kill

With drones becoming cheaper and more capable, the U.S. military has been investing heavily in anti-drone tech in recent years. However, while many of those systems involve literally shooting down drones, LMADIS essentially uses energy to render a drone useless.

That makes it a far cheaper countermeasure to a drone attack than, say, shooting a threatening device with a missile — meaning this first directed-energy drone "kill" might just be the first of many.
