A message for engineers

We're building counter-drone defense systems for the modern battlefield, where engagements happen at a tempo measured in months, not decades. Our systems, like Edda's AI point defense turret, are designed to engage multiple drones at ranges of 10-100+ meters. We're tackling the challenge of detecting and countering drones in a way that's both fast and low-cost. Our approach relies on a combination of passive acoustic sensors, like Vor, and high-speed engagement systems, like Atla's belt-fed shotgun system.

About

9 Mothers builds counter-drone defense systems for the modern battlefield — the engagements that legacy C-sUAS was never designed for. Hardware tempo measured in months, not decades.

Projects

Edda

AI point defense turret. Fast, low-cost, autonomous-capable engagement of multiple FPV drones at 10–100+ m range.

Vor

Passive acoustic sensor. Zero-RF, signature-quiet detection. Coarse tracking from intrinsic drone acoustics — feeds the rest of the kill chain.

Atla

Belt-fed shotgun system. Continuous-fire close-range engagement built for sustained drone swarms when ammunition discipline can't be the limit.

Gleipnir

A clean answer to one-way attack drones and Group 2 UAS. Cost-per-shot under $10K.
