To win in today’s highly contested electromagnetic spectrum (EMS) environment, L3Harris’ Distributed Spectrum Collaboration and Operations (DiSCO™) architecture enables the weaponization of electronic warfare (EW) data to counter advanced threats at the speed of relevance.
DiSCO technology is key to delivering real-time shared situational awareness, allowing planners, operators, analysts, and battle managers to understand the complex EMS operating environment. This is essential for orchestrating the use of non-kinetic effects across all domains.
“DiSCO’s technology provides the tools needed to orchestrate C2 across a mesh network of distributed sensors and jammers to enhance lethality and survivability for the U.S. and our partners,” said Ed Zoiss, President, Space and Airborne Systems, L3Harris. “We believe this is the only way to deliver the kind of next-gen electromagnetic spectrum operations capabilities needed at a scale. DiSCO is a perfect example of this commitment, and it isn’t just a glossy brochure – we have demonstrated real hardware and software at multiple exercises in several combatant commands across the globe.”
Joining the Battle at Talisman Sabre, U.S. Indo-Pacific Command
During Talisman Sabre 2025 in Australia – the largest bilateral military training event between Australia and the United States – L3Harris demonstrated DiSCO's capabilities to employ distributed multi-domain platforms in a remote theatre.
The company connected an aircraft and two autonomous surface vessels equipped with compact EW payloads that were streaming and fusing radio frequency (RF) signal information coming from attacking vessels to enable real-time situational awareness, signal analysis and tactical intelligence support.
DiSCO’s precision geolocation and autonomous reprogramming capabilities gave the U.S. Indo-Pacific commander actionable information on high-priority surface targets while countering incoming attacks. The L3Harris team also gained valuable insight into operational challenges and warfighter needs to guide future development.
Connecting Across an Ocean at DSEI in London, U.S. European Command
L3Harris joined Defence and Security Equipment International (DSEI) 2025 with a live DiSCO demonstration that combined communications data from an EW sensor onsite in London with live radar RF data from an EW sensor located at the company’s site in Clifton, New Jersey.

The team also integrated live radar RF data from New Jersey with prerecorded communications data from a Modular Electronic Warfare System (MEWS) sensor that was integrated on an uncrewed surface vessel in London.
These demonstrations proved DiSCO’s ability to incorporate communications and radar sensor data into a real-time cloud-connected common operating picture across thousands of miles. They also provide DiSCO’s ability to integrate a non-U.S.-built and fielded EW sensor with associated signal data.
Ensuring Global Electronic Warfare Superiority across all Combatant Commands
Modern adversaries will continue to employ advanced, long-range and agile threat systems that are difficult to detect, locate, identify and counter. Addressing these trends will require solutions that provide access to relevant EW data and can operate in heavily contested, congested and complex operational environments.
“We are investing heavily as a company to develop multi-domain, cloud-based and software-defined technologies to deliver this much needed next-gen capability,” Zoiss said.
Building on the success of Talisman Sabre, DSEI and ongoing internally funded development activities, L3Harris is planning more DiSCO demonstrations at upcoming exercises with U.S. and international partners. These events will further validate the need for DiSCO’s cloud-connected EW data sharing, advanced processing, and command-and-control functions to deliver electromagnetic battle management capabilities to the warfighter as quickly as possible.
