Intergalactic (St. George, UT) will supply thermal tech to L3Harris for the U.S. Navy’s NGJ-LB program, enhancing next-gen electronic warfare through advanced aerospace heat management systems.
St. George, Utah - May 1, 2025
Intergalactic, a St. George, Utah-based developer of advanced aerospace thermal management systems, has been selected by L3Harris Technologies (Salt Lake City) as the sole-source supplier of thermal systems for the U.S. Navy’s Next Generation Jammer – Low Band (NGJ-LB) program.
The NGJ-LB initiative, designed to replace the legacy AN/ALQ-99 Tactical Jamming System, is a key modernization effort to enhance airborne electronic warfare capabilities. In September 2024, L3Harris received a five-year contract worth up to $587.4 million to develop modular jamming pods for the EA-18G Growler aircraft, consolidating advanced processing and increased jamming capability within a system designed for easier maintenance and future technology upgrades.
Intergalactic’s role is to deliver a rugged, lightweight thermal management system optimized for high-kilowatt heat rejection in a constrained aerospace form factor. The passive system will use custom design strategies built around Intergalactic’s Boreas3 Heat Exchanger, a proprietary, laser-welded microtube technology that has passed full MIL-STD-810 environmental testing and flight qualification in other defense programs.
“We couldn’t be more thrilled to partner with L3Harris to provide a modern, lightweight, and rugged thermal management solution for the Navy’s NGJ-LB program,” said Brad Plothow, Intergalactic’s Chief Growth Officer. “L3Harris’ pod capabilities will provide a vital upgrade to the jamming capabilities of the Navy’s EA-18G aircraft fleet and protect U.S. military forces and global allies with enhanced electronic capabilities.”
As thermal loads in defense electronics continue to escalate, effective heat management is becoming a defining factor in system performance. Founded in 2016, Intergalactic set out to address this challenge by developing some of the smallest, lightest, and most advanced thermal systems available today — including both active and passive architectures, microtube heat exchangers, advanced turbomachinery, and high-voltage electronics with proprietary control software.
“When we founded Intergalactic, our goal was to enable the next generation of air and space breakthroughs by solving the thermal management problems that have kept so many innovations on the ground,” said Nick Kaiser, Intergalactic’s Chief Technology Officer. “The Next Generation Jammer program is exactly the kind of critical modernization effort that greatly benefits from our work to upgrade and validate a new and improved technology stack for robust, powerful, and lightweight aerospace thermal management.”
L3Harris will deliver operational prototype pods to the U.S. Naval Air Systems Command over the next five years for fleet assessment, along with test units for airworthiness and design verification. The NGJ-LB pods are intended to fly alongside legacy systems and will serve as a scalable foundation for future joint-force and allied capabilities.
