Array Defense builds layered detection, classification, and defeat systems for modern battlefield threats such as drones, gunfire, and low-flying aircraft, specifically in environments where RF jamming, GPS denial, and darkness degrade traditional sensors. Their flagship Hornet system uses passive, edge-based acoustic sensing with an on-device threat signature library and fusion layer that cues outputs to ATAK and BMS.

Problem
Traditional air-defense and security sensors rely on active RF, GPS, and optical modalities that degrade or fail completely under jamming, GPS denial, darkness, and adverse weather. This leaves military and security forces vulnerable to low-cost, fast-arriving threats like drones, gunfire, and low-flying aircraft that exploit those blind spots.
Solution
Array Defense provides a layered counter-threat platform that detects, classifies, and defeats drones, gunfire, and low-flying aircraft across the full engagement cycle. Their approach combines passive edge sensing, on-device signal extraction, and a software-defined threat library to identify threats without emitting a detectable signature. The Hornet system is the first product built on this intelligence layer and fuses classified threat data into a single operational picture, which is then cued directly to existing command-and-control platforms like ATAK and BMS. By keeping classification and fusion at the edge, they deliver real-time decisions without reliance on cloud connectivity or vulnerable communication links.
Target Audience
Primary customers are military and defense organizations, including ground forces, base security units, and homeland security agencies, that need reliable counter-UAS and counter-fire capabilities in contested or degraded sensor environments.
Features
- Passive acoustic sensing that operates without RF emission, maintaining stealth in contested environments
- On-device feature extraction and classification, enabling autonomous operation and minimal latency
- Software-defined threat library that grows through updates rather than requiring new hardware
- Fusion layer that correlates signals from multiple sources into a single coherent threat picture
- Direct integration and cueing with ATAK and BMS for seamless handoff to operational units
- Layered armoring and protection solutions for people, vehicles, and infrastructure behind the line
