Joby Aviation and L3Harris Technologies announced a new collaboration aimed at developing a hybrid vertical take-off and landing (VTOL) aircraft tailored for defense applications. The project focuses on creating a low-altitude platform capable of both piloted and autonomous flight, with potential roles in a range of military operations.
The initiative combines Joby’s experience in commercial aircraft design and manufacturing with L3Harris’ capabilities in integrating mission systems such as sensors, effectors, and communication tools. Flight testing is scheduled to begin later this year, with operational demonstrations planned during government exercises in 2026.
The aircraft will utilize a gas turbine hybrid propulsion system, currently being developed by Joby for its S4 platform. This system is designed to support extended range missions. In June 2024, the company conducted a 561-mile hybrid flight under a government contract, marking a milestone in long-range VTOL capabilities.
Joby also completed the acquisition of Xwing’s autonomy division last year and has since tested aircraft-level autonomous features. The technology is expected to support the optionally piloted nature of the proposed aircraft.
Representatives from both companies framed the partnership as a response to emerging defense requirements. Jon Rambeau, President of L3Harris’ Integrated Mission Systems, said the project aims to enable long-range crewed-uncrewed teaming. Joby CEO JoeBen Bevirt highlighted the company’s ongoing engagement with the U.S. Department of Defense and noted the readiness to transition from development to deployment.
