Quick Takeaways
- Electric air taxi manufacturing in the US is moving from pilot scale toward industrial-scale production.
- Automotive-grade manufacturing expertise is accelerating the readiness of eVTOL platforms for commercial deployment.
Recently, Joby Aviation announced a major expansion of its electric air taxi manufacturing footprint by securing a large production facility in the Dayton, Ohio region. This move supports the company’s ambition to scale electric vertical takeoff and landing aircraft output while strengthening its long-term manufacturing capacity in the United States.
The newly acquired facility spans more than 700,000 square feet and is scheduled to become operational within the year. It is expected to play a central role in Joby Aviation’s plan to double production capacity to four S4 aircraft per month by 2027, while also allowing room for additional expansion as demand for electric air mobility grows.
Scaling Electric Air Taxi Production Capacity
The Ohio manufacturing site complements Joby Aviation’s existing production locations across California and Ohio. Together, these facilities form an integrated manufacturing network designed to support increased aircraft output and operational efficiency.
To enable the planned production ramp-up, Joby Aviation initiated procurement of critical capital equipment in December. This investment is intended to support higher manufacturing volumes while maintaining quality standards required for commercial passenger service.
Key objectives of the expansion include:
Recent Manufacturing Milestones
Joby Aviation has continued to expand its production capabilities over the past year. In mid-2025, the company completed an expansion of its manufacturing facility in Marina, California, increasing its overall assembly capacity. Later in the year, it confirmed the start of propeller blade production at its Ohio operations, marking a key vertical integration milestone.
These developments align with the company’s broader strategy to control critical manufacturing processes while preparing for commercial deployment of electric air taxis.
Toyota’s Strategic Manufacturing Support
Toyota continues to play a significant role in supporting Joby Aviation’s manufacturing scale-up. The automotive major has invested heavily in the company, including a USD 500 million commitment made in late 2024, bringing its total investment close to USD 894 million.
Beyond financial backing, Toyota contributes expertise across:
Toyota also supplies key powertrain and actuation components, reinforcing Joby Aviation’s efforts to industrialize electric air taxi production with automotive-grade manufacturing discipline.
