LiquidPiston awarded $35M USAF contract to support development of rotary engine hybrid power system

LiquidPiston, a developer of compact, efficient engine technology and hybrid power systems, has been awarded a three-year, $35-million contract to support hybrid power system development. The contract was awarded by AFWERX, a Technology Directorate within the Air Force Research Laboratory, in partnership with AFLCMC, the US Air Force Life Cycle Management Center.

This award builds on an ongoing Phase II SBIR program supporting the 144th Fighter Wing, which is developing an Adaptive Basing Trailer to support rapid deployment of fighter jets.

The new $35-million contract includes $15 million in SBIR funding from the STRATFI program, announced in June 2023. The funding reflects growing acknowledgment of LiquidPiston as a driver of smaller, lighter, more efficient engines and hybrid power solutions for military applications.

With this award, LiquidPiston will design, develop, and qualify a 90+ horsepower heavy-fueled rotary engine, which will be incorporated into a modular Rotary Engine Hybrid Power System. This engine and platform can serve as the power pack for a variety of applications of interest to the Air Force, including unmanned aerial systems (UAS) propulsion, human- and cargo-carrying Organic Resupply Bus (ORB) capabilities, mobile operating bases, and vehicle auxiliary power units (APUs).

LiquidPiston’s STRATFI award continues the company’s noteworthy momentum as a leader in custom power solutions for the US Department of Defense. In the last year, it has also received a $9-million development contract from the US Army to develop a prototype core engine based on its XTS-210 design, as well as an $8.3-million award to revolutionize battlefield power generation, also for the US Army.

By working with the Air Force, we’re laying the building blocks for a new portfolio of engines in the 100-horsepower class. We’re excited to work with the Air Force on this program, providing logistical advantage to the warfighter. The technology being developed will have dual-use application, ultimately being scalable and adaptable to meet a spectrum of military—and soon commercial—needs.
