In today’s conflicts, defending the perimeter is no longer about walls and fences alone. Threats arrive from the air—fast, cheap, and hard to predict. FPV drones, loitering munitions, and larger aerial systems have become central tools of disruption, and they’re not going away. To counter this, Squarehead Technology’s acoustic systems can work as a scalable sensor networks that bring persistent surveillance and resilience to borders, infrastructure, and frontline positions.

On today’s battlefields, small patrols and dismounted units are often the most vulnerable. At night, when visibility is low, or in contested terrain where threats can appear without warning, maintaining constant vigilance is both exhausting and impractical. The Discovair G2+ from Squarehead transforms this challenge, establishing an immediate acoustic safe zone that provides 360° surveillance and early warning against drone threats.

Modern units face constant threats from drones and other aerial systems, even when stationary for only short periods, for instance during a column halt. In these moments, point defense — the protection of a limited area or unit for a short duration — becomes critical. Protecting troops and assets without adding to the burden of constant watch is essential. Discovair G2+ delivers a powerful protective dome of awareness that alerts soldiers the moment a threat enters their perimeter — enabling rest, repositioning, or safeguarding of assets with confidence.

We collaborate closely with border control forces, enhancing their protected perimeters with top-notch acoustic drone detection. Discovair revolutionizes the field by delivering accurate slew-to-cue detections, seamlessly directing high-precision sensors towards identified targets.

Discovair has been deployed in conflict, supporting the needs of allied forces to detect both small, and large drones. Detection allows forces to mitigate the threat, whether it is from a small ISR drone - or from a fire-and-forget kamikaze drone. The lightweight, and small physical and power footprint, allow for mobile and dismounted use, always using the sensors where they are needed the most.

Fighter jets are most vulnerable when they are sitting on the ground. A small drone can be a thousand-dollar weapon against a 100-million-dollar weapons system. Discovair provides near-field detection capability for high-value assets. When combined with an electronic warfare or kinetic kill effector, it forms a complete kill-chain that guards the high value asset.

The Discovair G2 has a small footprint - both in size, weight and power - and can be brought into most special forces’ operations. By employing multiple units and displaying alarms and user interface on a body worn phone display, the system provides an easy-to-use passive drone detection system that gives full hemispheric coverage - against any drone - providing the team with an invisible safety shield
