UNIFY.C2 and Squarehead Technology add passive acoustic sensing to multi-sensor counter-UAS platform

# Overview

UNIFY.C2 announced a strategic partnership with Squarehead Technology to integrate passive acoustic drone detection into UNIFY.C2's command-and-control and sensor-fusion platform. The move expands UNIFY.C2's sensor-agnostic architecture by adding acoustic detections to existing RF, radar, and electro-optical inputs.

# What the announcement says

UNIFY.C2 will accept Squarehead's Discovair G2+ acoustic sensor outputs and fuse those detections with other sensor sources within its single operational interface. The goal is to improve detection, classification, and tracking for low, slow, and small unmanned aircraft systems (UAS), particularly where RF methods alone are insufficient.

UNIFY.C2 CEO Jerry McGee described the platform as the "central command-and-control layer for layered counter-UAS architectures," and said integrating Squarehead's passive acoustic detection extends the platform's ability to detect and track threats in environments where RF-based systems alone do not suffice.

Squarehead's General Manager Defense, Espen Bøch, said the Discovair G2+ integration enables passive acoustic detection to be combined with complementary sensors in a unified command-and-control environment, giving operators faster, more confident decision-making based on a more complete situational picture.

# How the integration works

• Squarehead's Discovair G2+ sensor provides passive acoustic detections and tracks UAS by analyzing the sound signatures of rotorcraft and propeller-driven vehicles. The sensor does not emit RF or active signals.

• UNIFY.C2 receives acoustic detection and tracking data and fuses it with RF, radar, and electro-optical feeds inside its single operational interface. Correlated detections give operators a combined, real-time airspace picture.

• The fused display is intended to improve operator confidence and speed of decisions because multiple complementary sensors can corroborate a contact—acoustic confirmation where RF or radar returns alone may be weak or ambiguous.

# Operational implications

• Detection in RF-congested or RF-denied areas: Acoustic sensing provides a passive channel that is not affected by RF jamming, heavy RF traffic, or encrypted/stealthy communications between drones and controllers.

• Urban and cluttered environments: Small UAS that present weak radar signatures or ambiguous RF indicators are more likely to be detected and tracked when acoustic cues are added to the sensor mix.

• Multi-sensor correlation: Operators using UNIFY.C2 will see acoustic tracks alongside other sensor types, enabling faster identification and reduced false alarms when multiple modalities align.

# Who this is for

The announcement emphasizes three customer sets: defense organizations, public safety agencies, and critical infrastructure operators. All three typically need reliable detection and tracking at scale across complex operational environments.

# Next steps and positioning

UNIFY.C2 frames the agreement as consistent with its sensor-agnostic, scalable approach to counter-UAS command and control. Squarehead's comments indicate the Discovair G2+ is the acoustic element being integrated. The release does not specify deployment timelines, scale metrics, or procurement details.

# Bottom line

The partnership combines passive acoustic sensing with an existing fusion and C2 layer to address detection gaps for small, low, slow UAS in contested, congested, or RF-limited contexts. For agencies and sites that need corroborated detections across sensor types, the integration promises a more resilient situational picture without relying solely on RF-based sensing.
