Leading the Charge: L3Harris' Advanced EW Technologies for Superior Battlefield Advantage
December 09, 2025
-Today’s warfighters face increasingly complex and sophisticated challenges on the battlefield. Modern threats – such as drone swarms, signals that change frequencies and attempts to “spoof” or trick communications systems – necessitate solutions that are smarter, faster and more adaptable than ever before.
For decades, L3Harris has been a leader in electronic warfare (EW), designing systems to help warfighters detect, respond to and overcome these challenges. With an international presence across multiple domains – space, air, land, sea and cyber – L3Harris' advanced tools and solutions are trusted by defense customers worldwide.
“Today’s warfighters need tools that can adapt to rapidly changing threats and environments,” said Ed Zoiss, President, Space and Airborne Systems, L3Harris. “L3Harris’ advanced EW offerings are designed to be flexible, reprogrammable and ready to meet the demands of the increasingly complex battlespace.”
Proven, Flexible Tools Backed by Real-World Experience
Leveraging decades of expertise and a thorough understanding of the unique challenges faced by its customers, L3Harris provides advanced EW systems tailored to meet the needs of modern-day warfighters. These systems enable U.S. and allied forces to incorporate new functions into a single system or create a networked “system of systems.”
Such flexibility and adaptability is crucial for outpacing sophisticated threats. These systems have proven their value in real-world scenarios and are trusted for critical missions around the globe:
- Successful Demonstrations: Highlights include the U.S. Army’s Vanguard 2024, U.S.-Australian Talisman Sabre 2025 and U.S.-U.K. VANAHEIM 2025.
- Modernization Initiatives: Support includes Viper Shield upgrades to the global F-16 fleet, multi-platform counter-unmanned systems enhancements and new advancements in multi-domain munitions superiority and Counter Communications Systems.
- Advanced Capabilities: Sophisticated solutions like the EA-37B Compass Call, and modified G550s with electromagnetic attack capabilities for partners in Italy and Australia.
Offering an Integrated Enterprise Approach
L3Harris is pioneering comprehensive EW solutions across multi-domain operations. The Sky Warden, with its modular, mission-tailorable architecture, enables future integration with Launched Effects, positioning it as a potential EW asset for special operations forces.
Innovating Smaller, Smarter and More Adaptable Solutions
L3Harris continuously drives innovation across its portfolio of EW solutions in collaboration with universities, government researchers and partners. This results in tools that meet today's warfighters' needs by being:
- Compact and affordable: Smaller systems that require less power can be used on drones, portable platforms and even single-use devices like missiles and decoys.
- Flexible and reprogrammable: Systems can be frequently updated manually or automatically using artificial intelligence. Cognitive EW systems can learn to identify and respond to new threats, easing the burden on warfighters.
- Modular and scalable: Systems are designed to be quickly modified and work together as a network, making EW operations more flexible, affordable and future-ready.
With unparalleled expertise and a relentless commitment to innovation, L3Harris is revolutionizing electronic warfare. Cutting-edge solutions – including the next-generation multimission electromagnetic countermeasures system, Gladius – ensure that warfighters maintain a tactical edge, outmaneuvering and defeating the most sophisticated threats. As the global leader in EW, L3Harris stands ready to equip forces with the tools they need for total battlefield dominance, delivering security and superiority in an increasingly complex world.
