The U.S. Army is in the process of building requirements for a broad portfolio of electronic warfare solutions, reports Col. Daniel Holland, USA, Army Capability Manager for Electronic Warfare, Cyber Center of Excellence, Fort Gordon, Georgia.

Over the last several years, the U.S. Army has worked pointedly to build up its electronic warfare capabilities. From the early days of only having small groups of electronic warfare soldiers that ventured to counter radio-controlled improvised explosive devices in Afghanistan and Iraq, the Army has since retooled its efforts. The service is pursuing a broad campaign of development, is continuing to identify capability gaps and has successfully fielded more advanced tools to operate and dominate in the electromagnetic spectrum.

The U.S. Defense Department’s new electromagnetic spectrum (EMS) strategy will fall short of countering enemy EMS activities without specific organizational and process oversight, according to a report from the Government Accountability Office (GAO). The GAO is recommending greater oversight and specific metrics be built around designated leadership to ensure that the department’s own goals are met.

The Air Combat Command conducted successful cyber red team and penetration testing of its emerging cloud-enabled zero trust architecture, reports Lt. Gen. Chris Weggeman, USAF, speaking virtually on November 17 during the AFCEA Alamo Chapter's annual ACE conference.

The U.S. Air Force is on track to provisionally stand up its first and only Spectrum Warfare Wing (SWW)— known as the 350th SWW—this spring. The organization will be responsible for electronic warfare and so-called electromagnetic spectrum missionware. The 350th SWW’s role will run the gamut of providing such capabilities along the development, hosting, integration, testing and distribution phases, reported Lt. Gen. Chris Weggeman, USAF, deputy commander, Air Combat Command (ACC).

The U.S. is facing an increasingly congested, constrained and contested electromagnetic spectrum. Adversaries are challenging the United State’s dominance across the air, land, sea, space and cyberspace domains, which threatens our reliance on the spectrum. And because the United States depends on electromagnetic spectrum for much more than warfighting purposes, our nation’s economic wellbeing is at stake, says Defense Secretary Mark Esper.

For three years, the U.S. Army has been asking questions about how to converge cyberspace operations, electronic warfare and spectrum management capabilities at the corps level and below to deny, degrade, destroy and manipulate enemy capabilities. Now, officials say, they are drawing closer to answers.

In 2015, the service created a pilot program known as Cyberspace Electromagnetic Activity (CEMA) Support to Corps and Below. The CEMA concept integrates elements from offensive and defensive cyber, electronic warfare, and intelligence into expeditionary teams that support tactical units.

Work is needed to improve temporal, spectral and information understanding within the layers of the cyber domain to facilitate useful cyber-spectral and information maneuver. These advances could be incorporated into tactics, techniques and procedures as well as tactical and operational systems to enhance the overall military commanders’ decision process to achieve information dominance.

Most of the tactical cyberspace domain is spectrum-dependent and administered solely at the physical layer. Currently, warfighters cannot comprehend, much less maneuver within, a space that is inaccessible to them because they are not in a dimensionality to understand it. They operate in a cyber-spectral flatland.

Information warfare is an aggressive game of soccer where not only are all the fans on the field with the players, but no one is wearing uniforms.

In this representation of the electromagnetic interference (EMI) Resolution Process that supports electromagnetic spectrum (EMS) protection, each of the 10 functional areas of the process appears in approximation to where that activity should occur during an EMI event.

Safeguarding the electromagnetic spectrum is critical to success throughout the battlespace, but the ethos and resources needed to secure and defend this vital medium are lacking. 

The vulnerabilities from electromagnetic interference (EMI) affect the entire electromagnetic spectrum (EMS), requiring improved mitigation and resolution regardless of spectral bands, electronic systems or organizations. Although researchers have spent decades mastering the use of the spectrum, often pushing the envelope on capabilities, there has not been sufficient constructive action to overcome interference.

DARPA's Spectrum Collaboration Challenge (SC2) aims to ensure that the exponentially growing population of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum.

The Defense Department’s futuristic research agency has finalized its contest plans—backed by nearly $4 million in prizes—for the creation of a radio that can withstand wireless congestion.

It’s an ambitious competition led by the Defense Advanced Projects Research Agency (DARPA) to expand the communications capacity of the electromagnetic spectrum, especially at a time when the explosion of wireless devices and the dawning of the Internet of Things era has placed such a heavy demand for access to such a finite resource.

The realization that the U.S. military is losing its comfortable superiority over the airwaves has propelled the Defense Department to transform the electromagnetic spectrum into a new warfighting domain. This endeavor comes on the heels of the revolutionary doctrine change that established the cyber warfare domain not even a full decade ago.

Until now, cyberthreats have overshadowed electromagnetic spectrum (EMS) concerns. Chiefly, serious cyberthreats to U.S. commerce and national security caused by rapid technological changes siphoned attention and dollars from other domain coffers, including funding to improve the use of EMS.

Slide over cyber commands, the Defense Department could bear a new warfighting domain. The DOD is tinkering with the notion of recognizing the electromagnetic spectrum as a new warfare domain.

Such a policy change would come on the heels of the paramount decision in 2006 when the DOD added a fifth domain—cyberspace—to its arsenal. Though it has been a decade, cyber warfare is an area in which operators still wrestle with daunting guidelines to carry out warfare in the manmade field.

Given that, is the Pentagon ready for a sixth domain?

Will cyberwarriors no longer need the Internet?

The answer might be yes—in the future. For now, warfighters can stealthily wipe out an adversary and cause no physical destruction, thanks to electronic warfare (EW). EW has emerged as a warfighting domain where covert adversaries battle for the advantage. It is a powerful tool in the U.S. military’s arsenal that could prove a critical asset to win conflicts and become the weapon of choice for warfare in general. And technological improvements on the horizon could provide capabilities once reserved for science-fiction movies.

Only those who fully comprehend EW’s capabilities will control the battlespace of the future.

In an overpopulated city, on a small land mass, you can only stretch the living space so far before inhabitants are stacked one on top of the other. Such is the electromagnetic spectrum, a finite space in which the airwaves are literally bulging at the seams. It's now becoming more possible, however, to make those "living spaces" in the spectrum more efficient, thanks to a new Defense Advanced Research Projects Agency (DARPA) dynamic spectrum access (DSA) radio technology. The DSA radio technology developed under DARPA's Next Generation (XG) program is the focus of Technology Editor George I.
