U.S. production line sized for rate manufacturing of advanced thermal hardware and sensors.

WASHINGTON, Aug. 28, 2026 /PRNewswire/ -- Lyntris, Inc. (NYSE: LYNX), a defense technology company delivering sense-to-act connectivity solutions for the modern connected battlespace, today announced it has completed a multi-year investment to add phase change material ("PCM") capability at its Jessup, Maryland facility. The investment positions Lyntris as a vertically-integrated source for passive thermal management in seeker, sensor, and mission electronics applications, with production capacity available in Q3 2026.

Each new generation of defense electronics demands greater performance out of ever smaller form factors. Radars are expected to see farther with increased sensitivity and advanced seekers need to detect, track and destroy targets in highly contested environments.  All of that sensor capability generates heat that has to go somewhere. As density and power levels increase, cooling is often a limiting factor in sensor performance.

The usual answer is active liquid cooling, which works well on a ship or a ground vehicle with room to spare, but is not practical inside small, attritable sensors and seekers. Pumps, tubing, and reservoirs take up the volume, add weight, and introduce parts that can fail.

Phase change material heat sinks solve the problem differently. They work like a thermal battery: an engineered material inside the heat sink melts as the electronics heat up, absorbing energy. The electronics stay within their limits for the length of the mission, with no pumps and no plumbing. For missions measured in minutes, this solution allows recovery of the space, weight, and reliability an active cooling loop would have consumed.

These solutions support missile and sensor platforms entering high-rate production, where requirements can reach thousands of units, so a cooling approach that works on a prototype bench is worth little if it cannot be built the same way thousands of times. Lyntris sized the new manufacturing line anticipating that reality.

The line runs the full sequence in one, vertically-integrated facility, built for rate production rather than prototype quantities and includes precision machining of the heat sink structure, vacuum brazing, controlled PCM filling, thermal performance testing, and final assembly. These steps are typically split across multiple vendors, where each handoff adds qualification and schedule risk.

"Next-generation defense systems are being asked to deliver substantially more capability from increasingly compact platforms, and thermal management is often one of the limiting factors," said Matt Parisi, VP of Business Development at Lyntris. "Our investment in phase change material technology allows us to solve that challenge with a passive, highly efficient thermal solution that can be engineered and manufactured at scale. This is another example of Lyntris investing in differentiated technologies that address immediate customer needs and enable critical warfighter missions."

Lyntris expects to apply the capability first to seeker and sensor programs, and is in discussions with defense prime contractors and program offices on additional applications.
