Joby, L3Harris Unveil Military Hybrid VTOL Collaboration

Joby Aviation and L3Harris Technologies are partnering to develop an autonomous, hybrid gas-electric vertical takeoff and landing (VTOL) aircraft for military use, based on Joby’s S4 platform. The aircraft will offer both optional piloting and fully autonomous capabilities, targeting a variety of defense missions such as intelligence, surveillance, reconnaissance (ISR), and contested logistics. Flight testing is scheduled for fall 2025, with operational demonstrations planned for 2026. Joby brings experience from prior Department of Defense collaborations, while L3Harris contributes military systems expertise, aiming to create a VTOL with greater range and mission flexibility than earlier electric-only models. The partnership reflects a response to evolving defense needs and recent global conflicts. The companies hope successful tests will lead to a formal Department of Defense contract.
