Orbital Corporation (ASX: OEC) has received an order from US autonomous cargo aircraft developer MightyFly for three heavy fuel engine propulsion systems, extending its commercial customer base into middle-mile logistics. Autonomous Cargo AircraftMightyFly is developing autonomous hybrid cargo aircraft for commercial, government, and defence applications spanning distribution centres, hospitals, manufacturing facilities, military bases, and remote locations. MightyFly also demonstrated its autonomous cargo aircraft for the US Air Force in 2025, showing potential use across commercial and defence logistics. AATI subsequently ordered three additional systems, taking cumulative orders to eight engines and the value of propulsion systems and engineering integration services to more than US$750,000. MightyFly adds another commercial pathway alongside that service-led opportunity, with successful development expected to support a later aircraft production stage and possible additional propulsion orders.
