UAS Group 3-5 Offerings

A new class of U.S.-built, heavy-fuel propulsion systems for scalable unmanned operations

DeltaHawk’s Group 3–5 engine offerings are designed to deliver reliable, high-efficiency propulsion for modern unmanned aircraft systems operating in demanding defense environments. Built on a patented compression-ignition, heavy-fuel architecture, these powerplants enable extended range, long endurance, and simplified logistics through operation on widely available fuels such as Jet-A, JP-5, and JP-8. With a focus on scalable deployment, integration flexibility, and reduced lifecycle cost, DeltaHawk engines support both advanced mission systems and affordable mass across a wide range of unmanned platforms.
