Contract Overview

Hyliion Holdings announced that it will supply two multi‑megawatt KARNO Power Modules to the Naval Sea Systems Command (NAVSEA) in Philadelphia under a $41.7 million Office of Naval Research (ONR) contract. The award, first disclosed on July 22, represents the Austin, Texas‑based company’s largest military contract to date and lifts its cumulative ONR funding to more than $58 million.

Technical Details

The two modules are rated at slightly above 2 MW and 3 MW respectively and are built on Hyliion’s existing modular 800 kW architecture. They will be validated in both land‑based and maritime environments, with testing progressing from initial validation to upcoming at‑sea trials and eventual multi‑megawatt deployment. The technology is highlighted for fuel flexibility, electrical efficiency, low‑maintenance design, and the ability to reduce logistical burden while extending mission endurance. Acoustic and thermal signatures are kept low to suit maritime and expeditionary operations.

Financial Impact

Following the announcement, Hyliion’s stock has surged, up 110% year‑to‑date to $3.94 per share and gaining over 160% over the past twelve months. The contract contributes to a cumulative ONR investment exceeding $58 million, reinforcing the company’s defense revenue stream.

CEO Commentary

Founder and CEO Thomas Healy noted that the ONR contract accelerates development of the multi‑megawatt KARNO systems and broadens the range of naval platforms the technology can support. He indicated that Hyliion anticipates securing an additional $40‑$50 million in military contracts across multiple service branches this year, emphasizing that the agreements are founded on a deep technical partnership rather than a simple transaction. He added that the Office of Naval Research has been a “tremendous partner” and its continued investment reflects confidence in both Hyliion’s team and the KARNO platform.

Strategic Implications

The contract aligns with Hyliion’s strategy to run a common KARNO architecture across markets, leveraging the same platform for defense missions and distributed power applications such as data centers. By delivering multi‑megawatt capability while maintaining low acoustic and thermal signatures, the modules aim to enhance operational flexibility for naval platforms and support broader commercial deployments.
