Joby Aviation and defense contractor L3Harris to test autonomous hybrid aircraft

Joby Aviation, known for developing commercial electric air taxis, is expanding its focus through a partnership with defense contractor L3Harris Technologies to develop an autonomous gas-turbine hybrid vertical take-off and landing (VTOL) aircraft for military applications. This new aircraft will be based on Joby’s existing S4 platform, which has traditionally featured an all-electric powertrain. However, under a government contract, Joby demonstrated a hybrid prototype capable of flying 521 miles—more than twice the range of its battery-electric version. The collaboration aims to leverage L3Harris’s expertise in defense technologies to integrate sensors, autonomy, communications, and payloads, creating a mission-capable aircraft suited for Department of Defense (DoD) needs. Flight testing of the hybrid VTOL is scheduled to begin in the fall, with operational demonstrations planned for 2026. Joby has been working with the DoD for nearly a decade, focusing on meeting critical requirements such as extended range and mission flexibility.
