Hyliion’s KARNO Core Chosen as Power Platform for U.S. Navy’s USX-1 Defiant Trials

The U.S. Navy's Office of Naval Research, together with DARPA, has selected Hyliion’s innovative KARNO Core technology for full-scale sea trials aboard the USX-1 Defiant—an unmanned surface vessel (USV) built for autonomous ocean operations. This marks a pivotal moment for modular, low-maintenance power generation in maritime defense, spotlighting Hyliion at the intersection of next-generation naval capabilities and sustainability.

KARNO’s Modular Design Drives Autonomous Naval Innovation

Hyliion will deliver a drop-in 800 KW power system, consisting of four 200 KW KARNO Cores configured for the USX-1 Defiant’s unique unmanned design. These Cores, which operate on marine diesel, are engineered to showcase scalability, redundancy, and the ability to generate reliable power without any onboard human intervention—an essential trait for unmanned vessels.

The project’s focus isn’t just on efficiency: the USX-1 Defiant, developed for DARPA’s No Manning Required Ship (NOMARS) initiative, reimagines how naval platforms can function wholly without crew. That means every subsystem—including the power plant—must be resilient, quiet, and low-maintenance. KARNO’s modular generator architecture directly addresses these requirements.

Key Technical Highlights and System Details

The KARNO Core leverages a heat-powered linear generator approach, yielding not only increased efficiency and low maintenance, but also a reduced thermal and acoustic footprint. Such features make the system adaptable for both stationary and mobile applications beyond this naval test, hinting at broader industry adoption potential.

Significance: Unmanned Platforms and the Power Technology Race

The introduction of the KARNO Core into the Navy’s testing pipeline is more than a small technical win—it reflects growing momentum in the transition toward fully autonomous naval assets. As stated by Hyliion CEO Thomas Healy, “USX-1 Defiant represents a fundamental shift in how naval platforms are designed, powered, and operated.” The selection of Hyliion’s solution signals strong institutional confidence in their approach, especially as the global defense sector looks for efficient and resilient power solutions for future fleets.

With sea trials now moving forward, the performance of these Cores will be closely monitored by Navy stakeholders and, potentially, other industries—raising the question of how soon such modular, flexible power could migrate to commercial shipping or renewable energy storage use cases.

Looking Forward: Broader Applications, Early Stage Risks

While this news puts Hyliion squarely in the spotlight, it’s worth noting that the company is still in an early commercialization phase, with ongoing land-based testing and inherent risks typical of scale technology betas. Investors and industry observers will be watching for real-world data from the Defiant’s sea trials and potential follow-on contracts.

Ultimately, the successful demonstration of the KARNO solution in one of the Navy’s most advanced unmanned platforms could fast-track the adoption of Hyliion’s technology across other marine, stationary, and transportation markets. As power generation becomes increasingly critical in a low-carbon, high-efficiency world, Hyliion’s performance in the coming months will offer clues to how quickly modular, autonomous systems can reshape the energy landscape at sea and beyond.
