In 2020, the Department of Defense released its Electromagnetic Spectrum Superiority Strategy. According to the Hon. Dana Deasy (former Department of Defense Chief Information Officer):
“This strategy will help set the conditions needed to ensure our warfighters have freedom of action within the electromagnetic spectrum to successfully conduct operations and training in congested, contested and constrained multi-domain environments across the globe.”
Developing a strategy is a substantial initial step; however, turning strategy into actions at the tactical level is always complex. While many nations are still seeking to enhance and expand their electromagnetic spectrum (EMS) capabilities in an inherently complex operational environment, the United States is standing on the precipice of implementing its complete strategy. One method of operationalizing the strategy is to source and procure multi-mission, multi-user spectrum sensors used across the EMS enterprise and joint force. These sensors can break down acquisition silos and integrate rapidly into larger C2 networks for full spectrum dominance, achieving strategic goals today.
As the EMS is essential to modern warfare, EMS superiority is also critical to maintaining a military and economic edge. It enables the uninterrupted use of communications, navigation, intelligence gathering, and weapons systems. When a military has EMS superiority, it manages, observes, defends, and attacks with less chance of suffering casualties or setbacks.
For example, in a modern conflict, an enemy could use electronic jamming or cyberattacks to disrupt or disable US military systems that rely on EMS. Without electromagnetic superiority, military forces could be hampered or even rendered ineffective, making it difficult to carry out critical operations or defend against enemy attacks.
“America’s next war will be won or lost first in the Electromagnetic Spectrum (EMS). It is the invisible, essential, and physical foundation of every battlefield—it unifies all the warfighting domains: land, air, sea, space, and cyberspace.”
W.R. Alan Dayton in ‘Winning the Invisible Fight’
Regardless of the pressing need for investment in technology, the US military and fellow NATO members are dangerously close to losing the EMS superiority race. Over the past twenty years, competitor states have prioritized electronic warfare (EW). Conversely, NATO military thinking has often focused on low-intensity conflict rather than a strategic approach to security and warfare. This thinking led to EMS superiority dropping in the prominence it deserves—despite initiatives such as the ‘2020 Electromagnetic Spectrum Superiority Strategy’. What’s more, EMS systems and operations are highly technical and were stovepiped for so long that they remained hidden by larger procurement programs, such as warships, bombers, and armored vehicles.
In addition to spectrum superiority only occupying second place, four additional reasons have prevented full spectrum dominance.
While not a silver bullet, a major key to operationalizing the strategy lies in spectrum management, involving a one-sensor solution that functions in multiple missions with multiple users through remote access and easy placement.
While this type of solution is low-risk, it is a highly capable pillar of the EMS—the foundation upon which advanced electronic warfare and signals intelligence operations are built. Additionally, a spectrum management solution has a wide application when deployed in theater. This is because the process involves protecting friendly signals from interference or jamming—an inherent function of communications, and something that commanders can deploy with low risk.
Spectrum management solutions (hardware and software) allow users to monitor and analyze the EMS in real-time, providing critical information about the frequency usage of both friendly and enemy forces. The systems can detect, identify, and locate potential jamming, which can be passed up the chain of command in an interference report to Joint Electromagnetic Warfare Operations (JEMSO) and Cyber and Electromagnetic Activities (CEMA) warfare. Discerning jamming from friendly interference is a critical decision point for staffs and takes up about 70% of EMS missions during normal operations across the theater.
While desirable, specific EW and SIGINT equipment takes longer to procure and is only brought out in specific missions. Conversely, spectrum management solutions are rugged, easily deployable, and much cheaper than niche electronic warfare equipment. They can be purchased quickly and rapidly deployed on the battlefield—preventing the literal and metaphorical valley of death.
For equipment that has already been deployed, in a crisis, commanders only need to change the authority level and switch on spectrum management sensors for an EW/SIGINT mission. A simple administrative change is faster than deploying niche EW equipment near the frontlines—where spectrum management sensors are already protecting forward positions.
“In today’s modern battlefield, the joint force has to achieve electromagnetic spectrum superiority. We have gotten used to a process designed for permissive environments that are intended to minimize programmatic and technical risk at the expense of operational risk. One of my big functions inside the EMSSS I-Plan is to bring the operational risk component back into the department processes.”

On a tactical level, spectrum monitoring solutions are crucial for operators as they allow enemy communication signals to be detected and located. Moreover, spectrum monitoring solutions take spectrum management out of the office and into the field, helping operators ensure reliable communication and avoid disruption to critical operations. They set the theater and feed follow-on EW and SIGINT missions.
Operators’ insight, including high-quality spectrum information, such as jamming reports, helps give JEMSO and CEMA military commanders situational awareness. With the ability to pinpoint jamming and interference, commanders can make informed decisions about how to adjust communication plans. And with persistent real-time information about the electromagnetic spectrum, they can monitor it before a crisis and during combat operations.
The Russo-Ukrainian War has pushed the issue of spectrum warfare back to the front line. And, with its 2020 Electromagnetic Spectrum Superiority Strategy, the US is leading the way. However, fully operationalizing strategies with suitable solutions is challenging. Single-sensor, multi-mission, multi-user spectrum monitoring solutions can rapidly support the military in achieving spectrum superiority. These solutions are deployable and agile; they provide automated spectrum management, EW, and SIGINT capabilities. Moreover, they unite EMS stakeholders at the tactical level while facilitating complete spectrum understanding at the operational and strategic levels.
