Orbital’s 150HFE Engine Powers AATI’s AiRanger To First Flight And New Orders
Orbital Corporation's 150HFE propulsion system has powered its inaugural flight on AATI's AiRanger UAV, triggering follow-on orders worth over US$750,000 and signalling growth in UAV propulsion sales and service revenue.
- First flight success of 150HFE engine on AiRanger UAV
- Follow-on order increases total propulsion systems to eight valued over US$750,000
- Three additional engines to be shipped for fleet expansion and flight testing
- AATI's AiRanger holds US commercial BVLOS approvals for long-endurance operations
- Orbital anticipates recurring revenue via Power by the Hour model
Orbital's 150HFE Engine Clears First Flight Milestone
Orbital Corporation Limited (ASX:OEC) has marked a significant milestone with the successful first flight of its 150HFE heavy fuel propulsion system aboard American Aerospace Technologies Inc.'s (AATI) AiRanger unmanned aerial vehicle (UAV). This marks Orbital's entry into powering AATI's platform, which is already commercially approved for Beyond Visual Line of Sight (BVLOS) operations in the United States.
The flight validates the integration of Orbital's patented Flex DI™ direct injection technology into a UAV designed for long-endurance Intelligence, Surveillance, and Reconnaissance (ISR) missions, a demanding application that requires reliable performance under challenging conditions. Orbital’s propulsion systems have already accumulated over one million flight hours supporting US Naval operations, underscoring their robustness in harsh maritime environments.
Follow-On Orders Signal Confidence in Partnership
Following the successful flight, AATI placed a follow-on order for three additional 150HFE propulsion systems, lifting total orders to eight engines and engineering integration services valued at more than US$750,000. Orbital is set to ship these units imminently to support AATI's ongoing flight testing and anticipated fleet expansion.
This order reflects more than just hardware sales; Orbital CEO Stephen Pearce emphasised the strategic importance of customers capable of building sizeable fleets over time. As AATI scales its operations, Orbital expects further propulsion system orders and the gradual transition of these aircraft into its Power by the Hour (PBH) service model, which promises recurring revenue through engine maintenance and support.
AATI's Competitive Edge in Long-Endurance UAV Operations
AATI’s AiRanger platform benefits from commercial BVLOS approvals in the US, a regulatory hurdle that gives it a strong competitive advantage in the long-endurance UAV market. The company is actively pursuing government contracts focused on ISR missions, positioning itself for significant fleet growth.
Orbital's propulsion systems are tailored to meet the needs of such demanding applications, with features including multi-fuel capability, cold-start within two minutes, and a 750-hour time between overhaul. These attributes align well with AATI’s operational requirements in maritime and other challenging environments.
Power by the Hour: A Path to Recurring Revenue
Orbital’s Power by the Hour model complements its engine sales by providing long-term maintenance, overhaul, and performance support based on engine operating hours. This approach aims to generate predictable, recurring revenue streams as customer fleets expand and transition into full operational service.
With AATI's fleet expansion underway, Orbital sees a clear pathway to growing its aftermarket service business alongside ongoing propulsion system orders, potentially mirroring success seen in other US government UAV programs.
Bottom Line?
Orbital’s successful engine integration with AATI’s AiRanger and follow-on orders lay a foundation for sustained propulsion sales and service revenue growth, contingent on AATI’s fleet expansion and contract wins.
Questions in the middle?
- How rapidly will AATI scale its AiRanger fleet to drive recurring Power by the Hour revenue?
- What government ISR contracts might AATI secure that could accelerate demand for Orbital’s propulsion systems?
- How will Orbital’s propulsion technology compete as UAV endurance and regulatory landscapes evolve?
