Apart from being equipped with powerful munitions, the Israeli drones are also reportedly capable of carrying up to a ton of payload.

“This does not necessarily mean they can carry a one-ton bomb. It very much depends on the positioning of the munitions,” a senior Israeli military officer told the outlet.

Deployment of Armed Drones

Israel’s decision to develop and deploy armed drones was unveiled last year after it was classified for more than two decades.

Increasing the lethality of unmanned systems is part of an effort to bolster the country’s surveillance and strike capabilities.

In 2022, Jerusalem authorized the use of armed drones in West Bank operations. Usually, such drones transmit video or drop explosives before returning to base.

“No one will hear it, no one will see it coming,” the official further stated.

The Israeli government also asked local defense firms to desig
