Despite a ceasefire between Israel and Hezbollah, hostile drones continue to attack and kill Israeli troops, most recently 19 year-old Sgt. Idan Fooks. Hezbollah’s persistent use of their inexpensive yet effective unmanned systems begs the question: where are the counter-UAS systems meant to neutralize the threat?
Hezbollah for years focused on incorporating a wide range of UAVs into its arsenal, including reconnaissance quadcopters, fixed‑wing platforms, and explosive‑laden loitering munitions. They have become a key component of the group’s operational activity, used repeatedly in cross‑border incidents, striking military positions, damaging infrastructure, and contributing to the ongoing tension along the border.
Hezbollah has also learned from the over two years of war with Israel as well as from the five years of war in Ukraine. They have adopted first-person-view (FPV) and fibre optic drones that can be piloted with precision towards targets. Their drones are inexpensive, easily replaced, and capable of inflicting damage disproportionate to their cost.
In Lebanon, tanks and armored vehicles have been targeted. In several documented incidents, drones approached Israeli positions without triggering alarms. Hezbollah drones have also struck deep in Israeli territory since the war broke out. One attack, in October 2024 killed four 19-year-old soldiers at a Golani training base near Binyamina.
Video documentation showed that shortly after the incident where Fooks was killed, an explosive drone struck as a helicopter arrived to evacuate his body and six other injured soldiers. Following that deadly attack, the IDF carried out a wave of airstrikes and shelled the terror group in southern Lebanon.
Where’s our defenses?
While many have been successfully knocked out of the sky, it’s not enough. So where is the technology meant to stop these deadly threats?
Israel fields one of the most sophisticated air‑defense networks in the world, but these systems were originally designed to intercept rockets, missiles, and larger aircraft. There is also the Iron Beam that is said to be operational on the northern border and successfully intercepted several drones. And while the Iron Dome can handle drones, it is an expensive answer to such a cheap threat. These unmanned systems also present a different set of challenges such as minimal radar signatures, erratic flight paths and they can operate at low altitudes that can make detection difficult.
Israel’s defense‑tech sector includes dozens of companies developing counter‑UAS solutions, ranging from radar and electro‑optical detection systems to jammers, hard-kill interceptors, and more. Many of these technologies have been tested in controlled environments or deployed in limited operational settings. Dozens others are in use by dual-use, homeland security agencies around the world to secure critical infrastructure.
But the gap between available counter‑UAS technology and actual interception outcomes reflects the inherent difficulty of defending against these small, low‑signature drones in a dynamic conflict zone.
The border between Israel and Lebanon spans varied terrain, including mountains, valleys, and dense vegetation, all of which can affect sensor performance and successful neutralizations. Establishing continuous coverage across such an area is a complex undertaking, and gaps in coverage can be exploited.
And the threat continues to evolve.
Hezbollah’s drone capabilities have expanded rapidly, influenced by technological transfers from Iran and by lessons drawn from various conflicts like in Ukraine, the Caucasus, and the Middle East.
The IDF, like Ukraine, also iterates under fire. Reservists serving under Hezbollah fire in southern Lebanon understand the threat. Many come home and switch their uniforms to lab cloaks in order to work on c-uas technology. But even with a robust defense-tech ecosystem, integrating new systems into military operations, scaling them across wide areas, and adapting them to evolving adversary tactics takes time.
Too much time. Ceasefire periods have not stopped Hezbollah’s drone activity.
The persistence of drone launches shows that Hezbollah has a resilient supply chain so Israel has to have an effective, scalable solution for countering large numbers of these drones.
Israel’s North cannot fall into a war of attrition. The reality of the border cannot be one of drones consistently piercing through the sky. C-UAS defenses must move from development labs, demos and limited deployments to a fully scaled, layered, and adaptive operational reality.
