Revolutionizing Drone Warfare

The Challenge of Countering Drones

Drones have significantly altered modern warfare. These small, affordable devices can capture images and drop explosives, making them difficult to counter. ZeroMark, a U.S.-based defense startup, believes it has a solution to this problem.

ZeroMark’s Innovative Approach

ZeroMark aims to simplify the process of shooting drones out of the sky using bullets. The main challenge is that drones are fast and agile, making them hard targets even for skilled marksmen. ZeroMark’s system proposes adding aim assistance to existing rifles to help soldiers hit their targets more accurately.

How ZeroMark’s System Works

Technology Integration

“We’re mostly a software company,” ZeroMark CEO Joel Anderson tells The Zero Byte. The system involves placing a sensor on the rail mount at the front of a rifle, similar to where a scope would be. This sensor interacts with an actuator in the stock or foregrip of the rifle, adjusting the soldier’s aim while they point at a target.

Enhanced Targeting

A soldier facing a drone would point their rifle at the target, activate the system, and let the actuators stabilize their aim before firing. “So there’s a machine perception, computer vision component. We use lidar and electro-optical sensors to detect drones, classify them, and determine what they’re doing,” Anderson explains. “The part that is ballistics is actually quite trivial … It’s numerical regression, it’s ballistic physics.”

Precision and Efficiency

According to Anderson, ZeroMark’s system can perform calculations that are challenging for humans. “For them to be able to calculate things like the bullet drop and trajectory and windage … It’s a very difficult thing to do for a person, but for a computer, it’s pretty easy,” he says. “And so we predetermined where the shot needs to land so that when they pull the trigger, it’s going to have a high likelihood of intersecting the path of the drone.”

Market Potential and Skepticism

Venture Capital Interest

ZeroMark’s concept has attracted significant interest, including from venture capital firm Andreessen Horowitz. With militaries worldwide seeking effective counter-drone solutions, the industry is rapidly growing. However, many proposed solutions fail to deliver on their promises.

Field Testing and Evaluation

Whether ZeroMark’s machine-learning aim-assist system will be effective remains uncertain. Anderson mentions that ZeroMark is not yet deployed on any battlefield but has “partners in Ukraine that are doing evaluations. We’re hoping to change that by the end of the summer.”

Expert Opinions

“I’d love a demonstration. If it works, show us. Till that happens, there are a lot of question marks around a technology like this,”

Arthur Holland Michel, a counter-drone expert and senior fellow at the Carnegie Council for Ethics in International Affairs, tells The Zero Byte. He highlights the unpredictability and limitations of machine-learning systems trained on limited data.

Data and Physics Challenges

Anderson states that ZeroMark’s training data comes from various videos and drone behaviors, primarily from empirical information in places like Ukraine. However, Michel argues that the physics involved are complex. “People have been trying to shoot drones out of the sky [for] as long as there have been drones in the sky. And it’s difficult, even when you have a drone that is not trying to avoid small arms fire,” he says.

Future Prospects

While skepticism is warranted, it doesn’t mean ZeroMark’s system won’t work. “The only truly trustworthy metric of whether a counter-drone system works is if it gets used widely in the field—if militaries don’t just buy three of them, they buy thousands of them,” Michel says. “Until the Pentagon buys 10,000, or 5,000, or even 1,000, it’s hard to say, and a little skepticism is very much merited.”
