In today’s complex and contested defence environment, control of the electromagnetic spectrum (EMS) is not just an advantage, it’s a necessity. Electronic Warfare (EW) and Cyber Electromagnetic Activities (CEMA) sit at the centre of this unseen battlespace, where signals and counter‑signals constantly compete for information dominance. Preparing for a fight that is invisible, fast‑moving, and high‑risk demands more than conventional approaches. It requires the precision and predictive power of advanced modelling and simulation.
At MASS, we understand that achieving EMS superiority goes beyond deploying sophisticated hardware. It requires deep insight into how systems interact, how threats evolve, and how countermeasures will perform long before they reach the battlespace. Our proven expertise in EW and CEMA simulation delivers exactly that – transforming complex technical challenges into clear, actionable intelligence.
The Imperative of modelling and simulation
The constraints of real‑world testing in EW and CEMA are clear: high cost, logistical difficulty, and significant security considerations. At the same time, threats are developing quicker for physical testing alone to keep pace. Modelling and simulation closes this gap by providing a dynamic, secure, and cost‑effective environment in which to test, explore, and refine capability.
Simulation allows us to examine complex EMS interactions, predicting how systems will behave amid interference, deception, and advanced jamming. It enables rapid development of countermeasures by testing algorithms virtually against a wide library of threat models, supporting fast iteration and proactive mitigation. Crucially, simulation provides reliable, data‑driven performance insights before investment in physical prototypes, helping determine the likely effectiveness of new offensive and defensive operations. It also enhances training by giving operators access to realistic, repeatable scenarios that mirror the complexity of real-world missions.
Expertise in the Electromagnetic Battlespace
Our success in this field is built on our ability to combine deep operational expertise with advanced simulation technology to show how EW and CEMA systems will perform in real electromagnetic conditions. Our models replicate terrain, platforms, signal complexity, and a full spectrum of threats, giving users realistic, repeatable environments for concept development, mission rehearsal, and analysis.
We enable MOD and NATO teams to test systems and assumptions against current and emerging threats, strengthening risk awareness, survivability, and long‑term planning. Our tools also provide evidence‑based insight into countermeasure performance before costly prototyping.
By modelling the interaction between cyber activity and EW effects, we support coherent multi‑domain strategies that reflect real operational constraints. Every solution integrates seamlessly with existing workflows, enhancing decision‑making across capability development, operations, and training.
In short, our simulations help defence organisations understand today’s challenges, anticipate future ones, and maintain advantage across the electromagnetic domain.
