US Army Collaborates with 3dB Labs to Build Advanced Spectrum Awareness System for Modern Battlefields

The US Army has entered into a $6.1 million agreement with 3dB Labs to develop a next-generation electromagnetic spectrum situational awareness system, known as the Spectrum Situational Awareness System (S2AS). This cutting-edge system is designed to give combat units a clearer understanding and real-time control over their use of the electromagnetic spectrum — a vital domain in today’s digital and information-heavy warfare.

What is the Spectrum Situational Awareness System?

The S2AS is an advanced monitoring and reporting system that allows army commanders to detect, analyze, and manage electromagnetic emissions generated by friendly forces, such as those from communication equipment, command posts, and operational vehicles. By having real-time insights into these emissions, the system helps minimize the chances of detection by enemy forces, thereby improving the survivability of soldiers on the battlefield.

Why is Electromagnetic Awareness Important?

Modern warfare doesn’t just take place on land, sea, and air — it also takes place in the invisible but powerful electromagnetic spectrum. Many military operations rely on radios, sensors, GPS systems, and wireless communications. However, these tools also emit signals that can be tracked by adversaries using signals intelligence (SIGINT) equipment. By gaining better situational awareness of these emissions, US Army units can reduce their electromagnetic signatures, making it harder for enemies to locate or target them.

Key Features of the S2AS

• Real-Time Emission Detection: The system detects friendly force emissions in real time, enabling quick decisions and emission control.

• Dual Configuration: It is being developed in two versions — a lightweight, handheld unit for foot soldiers and a vehicular-mounted configuration for use on command vehicles and platforms.

• Self-Protection & Local Monitoring: The system helps protect individual units and provides broader spectrum insights for mission planning and tactical movement.

• Adaptable to Adversary Threats: The S2AS is designed with modern threats in mind, particularly focusing on countering enemy SIGINT capabilities.

• User-Driven Development: Continuous feedback is being gathered from soldiers and spectrum managers in operational units to make sure the final product meets real battlefield requirements.

Project Timeline and Development

The development of the S2AS is part of a 14-month phased prototyping and risk reduction process under the Consortium for Command, Control, and Communications in Cyberspace. The project is structured to move quickly from prototype to demonstration, with an operational test planned for fiscal year 2026.

According to Ken Strayer, Project Manager for Electronic Warfare and Cyber, “S2AS directly enhances the survivability and effectiveness of our soldiers on the battlefield.” The project’s approach ensures that the system evolves in sync with real-world demands and the ever-changing nature of electronic threats.

The Bigger Picture

As the battlefield grows increasingly digital, control over the electromagnetic spectrum has become a critical factor in mission success. The US Army’s focus on spectrum awareness aligns with its broader modernization goals, ensuring soldiers remain protected, connected, and a step ahead in electronic warfare.

The Spectrum Situational Awareness System marks a significant step forward in how military units interact with — and dominate — the invisible warfighting domain of the electromagnetic spectrum.
