Joby Aviation Acquires Resonant Sciences for $500M: A Strategic Pivot to Defense

What Is Resonant Sciences?

Resonant Sciences is a defense technology company founded in 2015 and based in Dayton, Ohio . It employs approximately 250 people, more than 90% of whom hold U.S. security clearances .

• Core technology: Radio frequency (RF) apertures, sensor systems, and mission systems for U.S. military aircraft, designed to operate in contested, GPS-denied environments .
• Revenue: Over $100 million in trailing-twelve-month revenue, representing approximately 40% year-over-year growth, with strong adjusted EBITDA generation .
• Profitability: Joby disclosed that Resonant carries high-teens adjusted EBITDA margins that are expected to expand .
• Customers: Long-cycle programs with the U.S. government, prime defense contractors, and next-generation defense technology programs .

Organizational Structure — A Dedicated Defense Division

Upon closing, Resonant will operate as Joby's dedicated defense business, keeping the Resonant Sciences name under its existing leadership .

• Leadership: Resonant's co-founder and CEO J. Micah North will continue to lead the unit .
• Absorbing existing defense work: Joby will fold its existing defense projects — including turbine-electric hybrid aircraft, hydrogen-electric aircraft, and autonomy technology — into this new defense division .
• Clear separation: The rest of Joby (the core air taxi business) remains focused solely on FAA type certification and commercial launch of its all-electric air taxi . This structure lets the defense unit generate near-term cash flow and profitability while the longer-timeline air taxi certification proceeds.

Strategic Rationale: Three Core Reasons

1. Immediate defense scale and classified access. Resonant brings established programs, specialized RF/sensor technology, and crucially, access to classified U.S. government programs that Joby could not win on its own .

2. Near-term revenue diversification. Joby has been burning cash on air taxi certification — it ended Q2 2026 with ~$2.3 billion in cash . The acquisition gives it an immediately EBITDA-positive defense business generating over $100 million in annual revenue, reducing its dependence on the long-timeline commercial certification .

3. Complementary technology. Resonant's mission systems and RF apertures complement Joby's aircraft platforms, enabling Joby to pitch complete electric/hybrid VTOL systems with integrated defense electronics to the Pentagon .

Broader Pattern: Acquisitions for Revenue Generation

This is consistent with Joby's strategy of using M&A to generate meaningful near-term revenue while its core air taxi program awaits certification.

Blade Air Mobility (August 2025): Joby acquired Blade's passenger helicopter rideshare business for up to $125 million . In Q2 2026, Blade contributed $36.2 million of Joby's total $38.6 million in revenue — that's 94% of total revenue . Blade's seat sales grew over 50% year-over-year, and Joby raised its full-year 2026 revenue guidance to $115–$125 million largely on Blade's strength .

Resonant Sciences (August 2026): The $500 million deal is a larger-scale version of the same playbook — acquire an already-profitable business with government contracts that provides immediate cash flow and strategic positioning.

Prior Defense Work: Hybrid Aircraft and Autonomy

Joby had already been developing defense-oriented aircraft before this deal. The company previously collaborated with L3Harris on a gas-turbine hybrid VTOL aircraft based on its S4 platform for defense applications. In 2024, Joby demonstrated a hydrogen-electric hybrid version of its aircraft that flew 521 miles without recharging — a significant milestone showing the platform's range potential for military missions. These existing defense programs (turbine-electric, hydrogen-electric, autonomy) will be absorbed into the new Resonant-led defense division, giving the combined unit both aircraft platforms and mission-system electronics under one roof. (Note: The L3Harris collaboration and 521-mile flight details draw from the user's question and Joby's public demonstrations, but could not be independently re-verified within the search budget.)

Key Uncertainties

• The deal's close in H1 2027 is subject to regulatory approvals, which could shift timing or terms.
• Whether Joby can successfully integrate a cleared defense contractor (250 employees, >90% with clearances) into a California-based eVTOL startup culture is an open execution risk.
• The L3Harris collaboration and the 521-mile hydrogen-electric flight details draw from the user's question and Joby's prior public demonstrations, but could not be freshly confirmed within the search budget for this analysis.
