Wisk Selects Liebherr-Aerospace as Strategic Supplier for Gen 6 Actuation System

Wisk Aero, a developer of autonomous all-electric vertical take-off and landing (eVTOL) aircraft, has announced the selection of Liebherr‑Aerospace & Transportation SAS as its long-term strategic supplier for the actuation system of its upcoming Generation 6 aircraft. The agreement encompasses development, certification, and full-rate production phases.

Scope of Supply

Under the agreement, Liebherr-Aerospace will deliver an electro-mechanical actuation system responsible for controlling flight surfaces — including flaperons, elevators, and rudders — as well as managing the tilt angle of the propulsion system. The contract spans from development through certification to scalable production, reinforcing supply-chain continuity.

Relevance to Aerospace Industry

For aerospace industry stakeholders, this partnership signals a converging point between advanced air mobility (AAM) systems and established aerospace suppliers. Wisk is aligning its aircraft architecture with a supplier experienced in certifiable flight-control hardware, while Liebherr is applying its modular actuation portfolio to a novel eVTOL architecture. The collaboration highlights the maturation of eVTOL supply-chains and the increasing role of Tier-1 aerospace suppliers in AAM platforms.

Technical and Certification Highlights

Liebherr will adapt its proprietary modular flight-control system, LiVCAS®, to accommodate Wisk’s all-electric aircraft architecture. The actuation system is designed with built-in redundancy to satisfy aviation safety standards, leveraging Liebherr’s flight-control experience in certification programs, combined with Wisk’s engagement with the Federal Aviation Administration (FAA) on novel systems.

Manufacturing and Supply-Chain Footprint

Manufacture of the actuation hardware — including actuators and electronic control units — will primarily take place at Liebherr-Aerospace Lindenberg GmbH in Germany and Liebherr-Electronics & Drives GmbH in Lindau, Germany. This manufacturing footprint underscores the use of established aerospace production facilities for novel air-mobility system hardware.

Strategic Implications

The selection reinforces Wisk’s pathway toward certification and full-scale production of its Gen 6 aircraft by anchoring a key flight-control subsystem with a Tier-1 aerospace provider. For Liebherr, the agreement represents an extension of its actuation portfolio into the evolving field of eVTOL aircraft. For the broader aerospace industry, it illustrates how advanced air mobility platforms are increasingly aligning with traditional aerospace manufacturing and certification ecosystems.

Outlook

As Wisk advances its Gen 6 aircraft program, successful integration and certification of the actuation system will be critical milestones. Given the importance of actuation hardware for flight-control integrity and safety assurances, this collaboration may set a precedent for other AAM developers seeking mature supply-chain partnerships. The aerospace industry will be watching how this development promotes scalability, reliability and certification readiness in the eVTOL domain.
