Accelerate Defense Modernization through Strategic Sourcing
Discover cutting-edge solutions from leading global suppliers
The Defence Science and Technology Laboratory (Dstl) has explored electromagnetic (EM) concepts, trialing advancements in what is referred to as “invisible war.”
Maintaining dominance in the EM spectrum is as vital to modern conflict as air, land, sea, and cyber domains. Disrupting an opponent’s command and control (C2) capabilities delivers a powerful edge on the battlefield.
Dstl’s Spectral Prophet trial showcased bold demonstrations of advanced EM techniques, merging previously distinct areas into cohesive systems. This initiative highlighted emerging technologies capable of offensive and defensive applications, including deception measures and countermeasures, paving the way for future innovations.
By leveraging distributed C2 frameworks, existing and next-generation radio frequency (RF) transceivers can be utilized with greater efficiency, enabling previously unattainable operational methods. Integrating data from diverse sensors and effectors enhances automation, giving military leaders better situational understanding and a decisive operational advantage.
The Spectral Prophet trial brought together expertise from major defence contractors, smaller enterprises, and academic institutions, underscoring the importance of UK investment in EM research. Such initiatives not only accelerate innovation but also create high-value job opportunities across the nation.
Dstl technology lead, Chris, said, “We are building the technology that allows information to get to where it needs to in near real time whilst filtering out information that isn’t needed.”
Dstl Spectral Prophet technical lead, Jon, added, “The trial and supporting programme draws on years of Ministry of Defence Chief Scientific Adviser funded research. We have funded a lot of work, for example, our university-based EM Hub. We’re building UK skills which supports the government’s growth agenda.”
Findings from these trials will guide decisions tied to the Strategic Defence and Security Review, offering insights into faster integration of emerging capabilities while optimizing costs. Advanced architectures and prototype technologies have been designed to reduce risks, extract lessons, and shape future procurement strategies.
