We build counter-UAS capabilities for the Department of Defense and Homeland Security. Our mission is to enable mass production of micro-guided missiles — affordable, scalable, and ready for the field. Our portable missile battery is designed for combined arm use, offering both mounted, dismounted, and low-collateral variants.

A new challenge

Drones are reshaping the modern battlefield — fast, cheap, and highly effective.




Traditional systems struggle to keep up.

70-80%

of battlefield fatalities come from drone strikes

$100,000+

kinetic solutions are used to counteract $500 drones

$500 Ukrainian drones decimate $100M Russian strategic bombers

Solution

We are building the best in class affordable and guided micro-missile pods for countering drones.

Different launching mechanisms

UAVs, ground vehicles, boats and more

Targets Group 1/2 Drones

Disables light, fast, and low-flying UAS

400+

meter range

10x cheaper

than the current solutions. Less than $10,000 per missile

15

micro-missiles per pod
