Israel Races to Counter Fiber-Optic Drone Threat as Detection and Interception Solutions Advance
The Israeli defense establishment is advancing a multi-layered effort to counter the growing threat of Hezbollah's fiber-optic and first-person-view (FPV) drones, which have caused casualties among IDF troops in southern Lebanon and are now believed to be operated by Hamas in the Gaza Strip. While progress has been reported on multiple fronts, officials acknowledge that a complete interception solution remains elusive.
The Jerusalem Post reported, citing military and security sources, that the defense establishment is moving from frequency-based detection to optical and acoustic detection systems, some of which have been deployed in the field in recent weeks. Tactical radar systems capable of detecting drones at ranges of hundreds of meters have been integrated into operational activity, and acoustic and small optical systems are being evaluated. The IDF has also adopted visual signature management and masking measures, including dynamic smoke screens during troop movements.
In parallel, the Defense Ministry has reported positive developments in efforts to counter Hezbollah's fiber-optic drones, with some systems already tested and in operational use and others still in development, according to defense officials. The ministry and IDF have divided the effort into several areas: detection, warning, passive defense, missile defense, drone interceptors, and future energy-based weapons designed to damage drone electrical circuits.
Israel Aerospace Industries (IAI) and other defense companies have presented the Defense Ministry and IDF with a range of solutions, including kinetic interception systems and energy-based systems, one of which uses electromagnetic force to capture the drone. Boaz Levy, chairman of IAI, told Maariv that given the green light from the Defense Ministry, accelerated production could deliver an initial supply of protective means within weeks and broader deployment within months.
A new partnership between Israeli defense tech companies High Lander Aviation and ThirdEye Systems was announced during the Airspace World conference in Lisbon. The agreement integrates ThirdEye's MeduzaX optical-detection system into High Lander's Vega uncrewed traffic-management platform, transforming it into a dual-use tool for national aviation authorities and defense operators. MeduzaX, already in operational use with the IDF, functions as a passive optical radar with a reported detection rate above 94% and a false-alarm rate below one percent.
In the field, soldiers have resorted to unconventional measures. The Jerusalem Post reported, citing KAN News, that IDF personnel in southern Lebanon contacted fishermen on the Sea of Galilee to request or receive donated fishing nets to bolster defenses. This was a personal initiative from soldiers, not part of an organized procurement process. In recent weeks, forces have used shade nets, soccer nets, and fishing nets, though not all types are effective against explosive drones. The IDF is reportedly working to create a uniform standard of defense and has placed an organized order for nets to be installed on buildings, vehicles, and protected positions.
Despite these efforts, the army admitted that there is still no complete solution for intercepting fiber-optic drones, which have a low radar and electronic signature, making them a major challenge. The IDF believes Hamas is operating fiber-optic drones in the Gaza Strip, similar to those used by Hezbollah, a Southern Command officer told Walla. The officer said the army must be prepared for scenarios involving gliders and rocket barrages, though there is no current assessment of escalation.
Hezbollah's drones have killed several IDF soldiers and wounded dozens more in recent weeks, despite a ceasefire. Last week, Col. Meir Biderman, commander of the 401st Brigade, was severely wounded in an explosive drone attack and was temporarily replaced.
In a related development, Yonatan Shalev, a candidate with the 'Together party' led by Naftali Bennett, commented on the fishing net report, saying, "As someone who almost died a few days ago from an explosive drone strike on the building where we were staying in Lebanon, I am ashamed to read such a report, and am forced to admit that it is true." He added, "I am ashamed that no one here is learning from mistakes, and mainly worried about what will happen in the next round in a few days."
Menahem, a veteran fisherman from the Galilee area, told KAN, "Those trying to solve the problem do not understand how to properly manage this issue." He said he knows groups with a large supply of fishing nets and offered help, saying, "This is to save lives and help the IDF."
The defense establishment continues to learn from operational incidents and footage released by Hezbollah, and officials said that "almost every day, there is a demonstration of relevant means to deal with the drones." The race to close the operational gap is ongoing.
