Joby Aviation builds out defense business with $500M acquisition
Filed by Ada Circuit
Joby Aviation has reached an agreement to acquire Resonant Sciences for $500 million, a move that will formally launch the company’s defense business. The deal, reported by TechCrunch, signals that Joby is looking to diversify beyond its core urban air mobility ambitions and establish a foothold in military and government markets. For a company still navigating the long and expensive road to commercial eVTOL certification, defense work offers a more immediate revenue stream and a strategic hedge. The acquisition reflects a broader pattern among advanced air mobility startups: lean on defense dollars to fund the path to civilian flight.

Joby Aviation’s $500 million acquisition of Resonant Sciences is more than a line item on a balance sheet—it is a strategic signal that the eVTOL industry’s survival playbook is being rewritten. The headline is about defense, but the subtext is about cash flow, certification timelines, and the brutal economics of bringing a new category of aircraft to market. Joby has long been a frontrunner in the race to commercialize air taxis, but that race is measured in years, not quarters. Defense contracts, by contrast, come with near-term revenue and patient, well-funded customers.
The move also fits a wider pattern. Startups that began with utopian visions of urban air mobility are increasingly turning to dual-use technology as a bridge to revenue. The U.S. military has shown real interest in vertical lift and autonomous systems, and a company like Joby—with its electric propulsion expertise—has capabilities that translate directly to defense applications. Acquiring Resonant Sciences appears to be a deliberate effort to bolt on specialized expertise rather than build a defense division from scratch. That is a pragmatic choice, but it also raises questions about focus and execution: integrating an acquisition while still pushing toward FAA certification is no small feat.
There is also a deeper tension here. Joby’s public narrative has been built around transforming city transportation, reducing emissions, and making air travel accessible. Defense work is a different kind of story—one that can generate controversy among climate-conscious investors and early believers. But the reality of advanced aviation is that government contracts often fund the very R&D that later enables civilian products. The $500 million price tag suggests Joby is serious about making defense a core pillar, not a side project.
The key question is whether this acquisition accelerates the path to commercial air taxis or delays it. Done right, defense revenue can subsidize the long certification slog and provide operational data. Done poorly, it can distract leadership and dilute the company’s mission. As TechCrunch’s report notes, this deal "kicks off" Joby’s defense business—and in doing so, it kicks off a new chapter for the entire eVTOL sector. The companies that survive this decade will likely be the ones that learned to serve two masters: the Pentagon and the passenger.
