IN Brief:
- AFRL has awarded DZYNE more than $6 million to develop Long-Range Grasshopper.
- Work covers endurance, modular payloads, GPS-denied navigation, reliability, and manufacturing readiness.
- The powered aircraft builds on a glider architecture used to deliver payloads weighing up to 500lb.
The Air Force Research Laboratory has awarded DZYNE Technologies more than $6 million to advance the Long-Range Grasshopper autonomous aerial delivery system.
DZYNE Technologies, now part of Ondas Sentinel, will continue work on powered Long-Range Grasshopper aircraft and Grasshopper glider units. The programme is intended to provide runway-independent precision delivery for dispersed forces operating where conventional airfields, roads, or protected logistics routes are unavailable.
The new phase will focus on longer range and endurance, modular payload integration, autonomous navigation in GPS-limited and GPS-denied environments, and improved reliability and manufacturability for larger-scale fielding. DZYNE has not disclosed the number of aircraft covered, the contract duration, or a target date for production readiness.
The award follows a 2024–2025 flight-test campaign that validated autonomous deployment, jet-engine air start, extended-range navigation, and precision payload delivery. Those trials moved the concept beyond an unpowered cargo glider by showing that the powered aircraft could be released, start its propulsion system in flight, navigate over distance, and deliver cargo without depending on a runway at the receiving end.
Ryan Hartman, chief executive officer of Ondas Sentinel, said: “Long-range, low-cost autonomous delivery is a mission imperative for the future fight.”
The existing Grasshopper glider architecture has carried loads of up to 500lb. The powered version retains the attraction of an air-dropped system while adding route flexibility after release, although the current announcement does not provide endurance, speed, release altitude, or launch-aircraft limits.
That absence of headline specifications places more weight on the engineering tasks named in the contract. A jet engine that starts after deployment must receive fuel and electrical power reliably while the airframe transitions from carriage or descent into controlled flight. The flight-control system must stabilise the aircraft, verify navigation, and manage any off-nominal condition before beginning the delivery route.
GPS-denied navigation introduces another constraint. An autonomous cargo aircraft cannot simply stop when satellite positioning becomes unreliable, but alternative methods accumulate error and may require combinations of inertial sensing, terrain or visual references, radio-frequency cues, and preloaded mission data. The contract does not identify the selected architecture, so claims about a particular sensor suite would be premature.
Modular payload integration is equally important for a logistics aircraft. A 500lb capacity is useful only when loads can be secured, balanced, released, and recovered without creating a separate engineering programme for every mission. Different payload shapes alter centre of gravity, drag, and handling, while batteries, medical supplies, ammunition, food, or repair parts bring different packaging and environmental requirements.
Manufacturability may prove more consequential than a marginal gain in range. AFRL has previously described the unpowered Grasshopper as a low-cost vehicle using commercial manufacturing methods, with an approximate production aim of $40,000 per airframe. That figure cannot be transferred directly to the powered version, whose propulsion, fuel, controls, and qualification burden are greater, but it explains why the programme is being designed around scalable output rather than exquisite, recoverable-aircraft economics.
Attritable logistics only works when cost and supply support routine loss. Engines, actuators, avionics, antennas, structures, and payload interfaces need to be available in quantity, while assembly must avoid specialist processes that take longer than operational demand allows. Reliability cannot be discarded, because failed deliveries waste both aircraft and cargo, but every additional subsystem must justify its effect on mission completion.
The system also fits the US Air Force’s Agile Combat Employment approach, which disperses forces and complicates conventional resupply. Smaller autonomous aircraft could move urgent loads without sending a crewed transport into the same threat area, although they would complement rather than replace high-capacity airlift. An aircraft carrying hundreds of pounds addresses a different logistics problem from one carrying pallets, vehicles, or bulk fuel.
DZYNE’s integration into Ondas Sentinel gives the programme a new corporate home while preserving the AFRL relationship behind the earlier trials. Corporate consolidation may provide access to manufacturing, mission software, and other autonomous-system expertise, but the contract will still be judged through repeatable launches, navigation performance, payload accuracy, reliability, and unit cost.
The next phase has moved past proving that Grasshopper can fly. AFRL is asking whether the powered design can travel farther, navigate with less external support, accept varied loads, and be manufactured in numbers large enough to affect logistics planning. Those tests will determine whether the aircraft becomes a practical delivery system or remains a promising demonstration without sufficient production depth.
