Joby Aviation to Acquire Defense Firm Resonant Sciences for $500 Million

Joby Aviation is acquiring Dayton-based Resonant Sciences for $500 million — $450 million in cash, $50 million in equity — in a deal expected to close in early 2027. Resonant Sciences, founded in 2015, brings 250 military-cleared employees and systems qualified across 20-plus airframes. Joby intends to use the acquired expertise to design and build stealth aircraft, establishing a dedicated defense division alongside its commercial air taxi operations.
