Hezbollah has expanded and adapted its drone capabilities during its ongoing conflict with Israel, increasingly drawing lessons from the war in Ukraine. Initially reliant on Iranian-made one-way attack drones that fly predetermined routes and detonate on impact, the group is now seeking more advanced and versatile systems that are harder to intercept.

A key development is the reported use of fiber optic-controlled drones, which are physically tethered to operators by thin cables. This makes them largely immune to electronic jamming and allows precise control over distances of up to 15 kilometers while carrying significant explosive payloads. Similar tactics and technologies have been widely used and refined on the battlefield in Ukraine, where both sides deploy large numbers of drones for reconnaissance and attack.

The shift comes as Hezbollah faces supply constraints and changing battlefield realities in southern Lebanon, where Israel has established a security zone along the border. With traditional rocket stockpiles reduced and infiltration more difficult, drones offer Hezbollah a flexible alternative for sustained attacks. The group appears to be investing in locally adaptable drone technology, potentially drawing indirect lessons from the Ukraine conflict through its regional allies.
