The Defense Ministry has reported positive developments in efforts to counter Hezbollah's fiber-optic drones, as Israel seeks solutions to a threat that has caused casualties among IDF troops on the northern front.
Some systems have already been tested and deployed in the field, while others remain in development, according to defense officials. The defense establishment is continuing to learn from operational incidents and footage released by Hezbollah.
Defense Ministry expands anti-drone effort
Following a joint situation assessment between the Defense Ministry and the IDF, officials decided to divide the effort against Hezbollah's fiber-optic drones into several areas, including detection, warning, passive defense, missile defense, drone interceptors, and future energy-based weapons designed to damage drone electrical circuits.
Officials also decided to test a variety of systems, technologies, and operational methods. Some of the systems have already undergone testing and are in operational use, while others remain in development.
"Almost every day, there is a demonstration of relevant means to deal with the drones," a security source said. "In some cases, it is possible to declare them operational."
New detection systems enter the field
Last week, tactical radar systems capable of detecting drones at ranges of hundreds of meters were integrated into operational activity. At the same time, acoustic detection systems and small optical systems are being evaluated as part of the broader effort to identify incoming threats.
"We are after several successful experiments and demonstrations that helped us choose which companies we want to use to provide systems," a security official said. "We chose between two or three companies, depending on the types of physics, and with very few systems that can already be said to be in operational evolution."
The official said one of the main challenges remains reducing false alarms and improving reliability.
"The combination of optics and acoustics should enable detection at relatively large ranges with a high level of reliability. We are making good progress here," the official said.
According to decisions made so far, every outpost is expected to receive a system of this type in the coming weeks.
Interception challenges remain
Various systems designed to intercept drones using drones have been tested, though none have yet achieved a success rate above 50%, according to defense officials.
"This is not exciting news, but on the other hand it is better than nothing. We will continue to hone them operationally. We will learn lessons and improve," a security official said.
Officials also highlighted challenges related to deploying sufficient systems across multiple locations. The Defense Ministry has additionally begun distributing the "Dagger," described as an advanced anti-drone sight, with some systems already reaching operational units.
At the same time, development continues on energy-based weapons. Officials described those capabilities as a long-term solution rather than one expected to be deployed in the near future.
The Defense Ministry has also deployed a limited number of portable laser systems and is examining additional technologies designed to blind drones. Officials stressed, however, that the effectiveness of laser systems depends on successfully detecting and tracking the drone first.
Israel learning from Ukraine war
The Defense Ministry and the IDF are continuing to study operational footage, field documentation, and videos released by Hezbollah as part of an ongoing effort to improve defenses.
Officials are also drawing lessons from the Russia-Ukraine war, including demonstrations conducted by Israeli startups involved in drone interception efforts.
"In the end, there is no good solution for fiber-optic drones in Ukraine either," a security source said. "There is a destruction zone there that started at five kilometers and expanded to twenty-five kilometers, and anyone who moves against it there knows that the chance of survival is low."
Meanwhile, Prime Minister Benjamin Netanyahu has approved a special budget dedicated to drone-related threats. According to defense officials, part of the funding will address immediate operational needs, while another portion will be directed toward future threats that have yet to emerge.
