AVILUS Wespe

The AVILUS Wespe is a German uncrewed coaxial-rotor helicopter designed to move cargo or casualties without a crew aboard, built by a Bundeswehr-pulled Munich startup and first flown in June 2026.

Overview

The Wespe is an uncrewed helicopter developed by AVILUS, a German defense-technology startup based near Munich, for tactical logistics and casualty evacuation rather than strike. It uses a coaxial main-rotor layout with no tail rotor and is designed to carry a payload of roughly 200 kg over about 300 km in its piston-engine form, according to the company's figures reported by hartpunkt and the trade outlet Uncrewed Systems. AVILUS positions it as a system that can fly resupply or medevac missions in conditions where a crewed helicopter would be too exposed or too costly to risk.

The name is German for "wasp." It should not be confused with the Second World War-era Wespe (Sd.Kfz. 124), a self-propelled 10.5 cm howitzer built on the Panzer II chassis; the two share only a name.

It is one of three uncrewed aircraft AVILUS has unveiled since 2025, alongside the electric Grille medevac multicopter and the fixed-wing Bussard. As of mid-2026 it remains a flight-test prototype, not an in-service system.

Development

AVILUS was founded in 2021 and is based in Bavaria, near Munich. Its origin runs through the Technical University of Munich: according to Uncrewed Systems, the founding engineers were PhD students at TUM's Institute of Flight System Dynamics under Professor Florian Holzapfel, brought together to answer a Bundeswehr request for a "flying stretcher." Ernst Rittinghaus — described there as the company's principal investor and CEO — came from the ground-evacuation-vehicle world and seeded the effort, and AVILUS acquired the necessary assets from ambulance-maker Binz. Max Söpper is CTO, Niclas Bähr COO and Daniel Dollinger head of design.

The Wespe was first shown publicly at the Bundeswehr open day (Tag der Bundeswehr) in late June 2025, per hartpunkt. Its maiden flight followed on 1 June 2026, when the first-generation aircraft, tail number "9Y-01," demonstrated stable hovering plus forward and lateral movement, remotely piloted from the RasCore Ground station, according to AVILUS. Aviation Week reported AVILUS flew two rotary-wing UAS in three days — the Wespe on 1 June and its electric Grille on 3 June — though some outlets, including Оборонка, dated the Wespe flight to 2 June.

Design & capabilities

The Wespe is a coaxial-rotor helicopter with no tail rotor, the tail carrying a rudder instead, per Uncrewed Systems. Stacking two counter-rotating main rotors on one mast cancels torque and drops the exposed tail rotor, giving a more compact, less strike-prone airframe. AVILUS describes it as modular: beyond cargo and casualties it can carry electro-optical sensors for reconnaissance, per hartpunkt.

Two figures anchor the piston version: a 650 kg maximum take-off weight and a 200 kg payload carried up to 300 km at a 120 km/h cruise, on a 180 kW (245 hp) reciprocating engine, per Uncrewed Systems and hartpunkt. With its landing gear retracted, the aircraft packs into a standard 20-foot ISO container. Secondary sources put the main-rotor diameter at roughly 6.5 m, a figure not confirmed in primary company material and best treated as reported.

Control and resilience come from AVILUS's in-house RasCore avionics, which the company says resist electronic jamming and are shared across its drone family, per hartpunkt. In the sibling Grille program, Uncrewed Systems describes that stack as using jam- and spoof-nulling antennas and a tactical-grade inertial reference unit that navigates without satellite signals — the GPS-denied resilience that matters against Russian electronic warfare, though the Wespe's own navigation performance is not yet documented. Rotor-control actuators come from Volz Servos, per drones-magazin, and sensors from Hensoldt. AVILUS also pitches the Wespe as ITAR-free and EASA Specific Category-cleared, a draw for European buyers, per DroneXL.

Variants

Two powerplant variants are planned, differing mainly in lift:

• Piston variant — a reciprocating engine giving a 650 kg maximum take-off weight, a 200 kg payload and a 300 km range at 120 km/h cruise, per Uncrewed Systems and hartpunkt. The 9Y-01 first-flight aircraft is the piston prototype.
• Turbine variant — a larger version that raises maximum take-off weight to 900 kg and payload to 350 kg, per hartpunkt and reporting summarized by Unmanned Systems Technology. Its flight status is not established; the demonstrated aircraft is the piston type.

Combat record / operational use

The Wespe has no combat record and no operational service. As of mid-2026 it is a flight-test prototype that has completed a single reported maiden flight; BattlePolicy covered that milestone in its news report on the first flight. AVILUS's medevac experience to date sits with the electric Grille, which the iMEDCAP consortium demonstrated in a live autonomous-evacuation pilot at NATO's Vigorous Warrior 2026 exercise in Estonia, per AVILUS — the Wespe itself was not part of that demonstration.

The demand case is drawn from Ukraine. Reuters reported in May 2026 that Ukrainian units are concentrating strike drones on Russian logistics and rear areas roughly 30 to 180 km behind the line — the band where a crewed transport helicopter flying ammunition or wounded would be most exposed. AVILUS markets the Wespe for exactly those conditions: an aircraft that can be risked, and lost, where a crewed machine cannot.

Advantages

• No crew aboard, so resupply and casualty-evacuation sorties can be flown into contested airspace without risking aircrew.
• Coaxial rotor with no tail rotor gives a compact footprint and removes a fragile, obstacle-prone component; the aircraft is designed to fold into a 20-foot container for transport.
• A useful payload/range combination for a system this size — about 200 kg over 300 km (piston), rising to 350 kg with the turbine variant.
• In-house RasCore avionics designed for jamming and spoofing resistance, drawing on GPS-denied navigation techniques proven in the sibling Grille program.
• Marketed as ITAR-free and EASA Specific Category-cleared, easing procurement and operation for European buyers rearming outside US export controls.

Drawbacks / limitations

• Immature: a single reported first flight in June 2026, with the flight envelope and mission systems still to be expanded. No service entry, order or delivery has been confirmed.
• Published performance figures are company-stated and largely single-sourced; payload, range and cruise numbers have not been independently verified in operational testing.
• The turbine variant, self-protection fit and full-autonomy behavior are described in prospectus terms, not demonstrated.
• Modest speed (120 km/h cruise) and payload relative to crewed medium-lift helicopters limit it to a supplementary role, not a replacement for larger airlift.
• AVILUS is a young, pre-revenue company; production capacity and unit cost for the Wespe are not publicly established, and scaling from prototype to fielded fleet is unproven.

Counterparts

The BattlePolicy Lexicon does not currently hold a like-for-like counterpart: there is no other uncrewed cargo or medevac rotorcraft catalogued here, and the crewed medium-lift utility helicopters whose risky resupply and casualty runs the Wespe is meant to offload (the Mi-8/Mi-17 and UH-60 class) are likewise not yet entered. The Wespe's nearest relatives are its own AVILUS stablemates — the electric Grille medevac multicopter and the fixed-wing Bussard — and a broader wave of European uncrewed logistics rotorcraft now in development. Those parallel programs are moving in step rather than competing head-to-head, and none is a fielded system, so a genuine peer comparison is not yet possible. This section will be expanded as comparable uncrewed rotary-wing logistics systems enter the Lexicon.

Outlook

The Wespe's trajectory depends on turning a maiden flight into a demonstrated capability and, ultimately, a Bundeswehr requirement. AVILUS says its next steps are to widen the flight envelope and integrate mission-control functions, per AVILUS. Its stated production ambition is aggressive — up to 50 units per type per year, roughly 150 aircraft annually across Grille, Wespe and Bussard by 2027-28, per Uncrewed Systems — but that is a projection, not a booked order, and the Wespe is the least mature of the three. Near-term signals to watch: a firm Bundeswehr trial or order for the Wespe (as distinct from the further-along Grille), the turbine variant flying, and independent verification of the payload and range figures.
