“Resonant has built an exceptional business that combines advanced technology, vertically integrated production capabilities and deep customer trust,” Joby founder and CEO JoeBen Bevirt said in a company press release announcing the deal.
What the transaction is: $500 million purchase and timeline
Joby Aviation agreed to acquire Resonant Sciences for $500 million in a deal the two companies announced on August 11, 2026. The consideration is roughly $450 million in cash and $50 million in Joby common stock. The parties said the transaction is expected to close “in the first half of 2027,” and that completion is subject to regulatory approval.
Resonant Sciences in Dayton will become Joby’s defense business
Resonant Sciences, a military-technology firm based in Dayton, Ohio, will continue to operate under its current name after closing and will serve as Joby’s dedicated defense unit. The press release states Resonant will be led by its co-founder and CEO, J. Micah North, and that Joby intends to fold its existing military work into the new defense arm.

End the scrambleTechnical priorities: autonomy, RF sensing, dual-use propulsion
The companies described an “early focus” on integrating Joby’s in-house autonomy stack with Resonant’s radio frequency (RF) sensing and signal-processing capabilities. Resonant is described in the release as a manufacturer of RF and mission systems “among other technologies.” Joby said the defense unit will concentrate on autonomous technology and on “dual-use turbine-electric and hydrogen-electric aircraft,” while Joby’s commercial efforts will remain focused on the all-electric S4 air taxi.
Military posture and prior testing
Joby has previously pitched all-electric air vehicles to military users, but the press release notes that testing with the US Air Force found that fully electrified aircraft “lacked the range necessary for more demanding defense missions.” The company last year announced a partnership with defense contractor L3Harris for a military-specific version of the S4 modified with a hybrid-electric powertrain — a move the release framed as part of a broader industry pivot toward hybrid-electric solutions for military applications.
Financial maneuvering: equity distribution agreement
Alongside the acquisition announcement, Joby filed a Securities and Exchange Commission regulatory filing showing it had entered an equity distribution agreement with financial firms to sell up to $750 million of Joby common stock. The companies framed the transaction as increasing scale for “the next phase of Resonant’s growth” and enabling opportunities that “neither company could address alone,” a line quoted from Resonant CEO J. Micah North in the release.
How technologists, defense buyers, and investors should take note
- Technologists and security teams: the stated early integration priority — combining Joby’s autonomy stack with Resonant’s RF sensing and signal processing — is the concrete technical deliverable announced today. Engineers working on autonomy, RF integration, and electronic countermeasures will likely be the teams most directly affected by the new company focus described in the release.
- Defense procurement leaders and the US Air Force: the release positions the deal as a response to “a broader shift in defense priorities toward” low-cost autonomous aircraft with resilient communications, sensing and electronic countermeasures. The companies said they intend to pursue military opportunities that leverage hybrid- and turbine-electric propulsion as well as hydrogen-electric concepts.
- Investors and capital markets: Joby’s separate equity distribution agreement — authorizing up to $750 million in common stock sales — and the $450 million cash component of the acquisition are explicit financial moves tied to the transaction and to expanding Joby’s defense-facing capabilities.
The acquisition ties together three threads laid out in the companies’ statements: Resonant’s RF and mission-systems capabilities, Joby’s propulsion and autonomy work, and an expressed market shift by defense buyers toward lower-cost autonomous systems with resilient sensing and communications. The deal’s completion, the companies reiterated, will turn on regulatory approval and the planned close in the first half of 2027 — and the success of the integration will be measured by whether the combined entity can deliver the hybrid, turbine-electric and hydrogen-electric platforms and autonomous systems the release positions as the next phase of growth.
