Israel's Esh-Tech Unveils DroneLight: A Pulsed Laser That Kills Drones in Seconds and Costs a Fraction of Rivals | International Daily Finance
AI Analysis
Israeli firm Esh-Tech has unveiled 'DroneLight,' a pulsed laser counter-UAS system designed for rapid drone destruction. The system boasts a significantly lower cost (3-4x less) and power draw (4kW) compared to existing laser/microwave solutions, and is vehicle-mountable. Esh-Tech’s focus is on ‘hard-kill’ solutions, recognizing the limitations of RF jamming against increasingly autonomous drones.
Key Takeaways
- DroneLight can reportedly destroy drones in 1-2 seconds.
- The system is designed to counter low-cost, swarming drones – a key threat identified by Israel based on experience with Hezbollah, Iranian-backed militias, and Hamas.
- Esh-Tech prioritized 'hard-kill' (physical destruction) over 'soft-kill' (RF jamming) due to the increasing resilience of drones to electronic warfare.
- The system’s low cost is intended to address the economic asymmetry of defending against inexpensive drones with expensive interceptors.
- DroneLight will be showcased at the Eurosatory defense exposition in Paris.
Why It Matters
This development could significantly alter the economics of counter-drone warfare, making effective defense against drone swarms more affordable and scalable. A successful, low-cost hard-kill system like DroneLight could become highly sought after by militaries facing similar drone threats, potentially shifting the balance in asymmetric conflicts. The system's vehicle mountability suggests a focus on tactical, mobile defense.

Israel has once again moved to the front of the global race to solve one of the modern battlefield’s hardest problems: how to knock cheap, swarming drones out of the sky without spending a fortune in the process. A new Israeli defense startup called Esh-Tech has unveiled a pulsed laser system named DroneLight that it says can destroy hostile drones in one to two seconds, draws only 4 kilowatts of power, mounts on a standard armored vehicle, and costs three to four times less than the laser and microwave systems already on the market. The company plans to put the weapon on public display at the Eurosatory defense exposition in Paris this month, according to Breaking Defense, which first reported the details in an interview with the firm’s chief executive.
For a country that has spent the past several years absorbing relentless drone attacks from Hezbollah in the north, Iranian-backed militias across the region, and Hamas remnants in Gaza, the arrival of an affordable, scalable hard-kill laser is more than a product launch. It is a potential turning point in the economics of air defense, an arena where Israel has consistently outpaced larger and wealthier militaries by pairing engineering ingenuity with battlefield urgency.
Why the Drone Problem Demanded a New Answer
The core challenge of counter-drone warfare is cost. A single small quadcopter rigged with explosives can cost a few hundred dollars, yet the interceptor missiles traditionally used to shoot such threats down can cost tens or even hundreds of thousands of dollars apiece. When an adversary launches dozens of drones at once, the defender bleeds money even when it wins every engagement. Israel understood this asymmetry earlier and more painfully than most, having watched Hezbollah deploy drones with ranges of up to 30 kilometers against both military positions and civilian communities.
Esh-Tech’s leadership set out from the beginning to attack this exact problem. “From day one, we tried to find a solution to counter UAVs, primarily small drones. We understood this would be the next threat,” chief executive Erex Riahi told Breaking Defense. The company concluded that soft-kill radio frequency jamming, while useful, was being steadily outpaced as drones grew more autonomous and resistant to electronic interference. The team chose instead to bet on hard-kill, meaning physically destroying the drone rather than disrupting its signal. “We saw that soft-kill RF solutions were constantly evolving, and with the rise of fiber optics we understood we needed hard-kill capabilities, so we bet on hard-kill to destroy drones,” Riahi said.
That decision reflects a broader strategic clarity that has defined Israel’s defense sector. Rather than chasing incremental upgrades to existing approaches, Israeli engineers repeat
