Joby Collaborates with L3Harris “to Explore Defence Applications for Autonomous Hybrid VTOL Aircraft”
Joby Aviation and L3Harris Technologies recently announced a collaboration to explore opportunities for developing a new aircraft class for defence applications, reports a press release.
Joby’s development of its gas turbine hybrid VTOL aircraft for the current S4 platform, following the acquisition of Xwing, has demonstrated aircraft-level autonomy. The VTOL showcased an industry-first 561 mile hydrogen-electric hybrid flight in June 2024.
It is designed for low-altitude missions and offers the versatility of being optionally piloted, enabling both crewed and fully autonomous operations.
The release explains, “The partnership leverages Joby’s existing commercial aircraft development program and leading manufacturing capabilities, combined with L3Harris’ proven expertise on platform missionisation including sensors, effectors, communication and collaborative autonomy.” The company is described as “The trusted disruptor in the defence industry.”
Flight testing is expected to start this Autumn with the two parties planning to perform operational demonstrations during government exercises in 2026.
JoeBen Bevirt, Founder and CEO of Joby Aviation, commented, “We have worked closely with the Department of Defence over the past decade to give them a front row seat to the development of our dual-purpose technologies, and we’re now ready to demonstrate and deploy it.”
He continued, “Our country depends on companies like ours moving at pace, and we have the team, the technology and the platform to do just that.”

Jon Rambeau, President of Integrated Mission Systems at L3Harris, added, “The next-generation of vertical lift technology enables long-range, crewed and uncrewed teaming for a range of missions. We share a vision with Joby to deliver urgently-required innovation by missionising VTOL aircraft for defence needs.”
