Adds To City’s History Of Advanced Aerospace Manufacturing

Joby Aviation, a Santa Cruz, California-based developer of electric air taxis for commercial passenger service, announced it has added the manufacturing of propeller blades at its Dayton, Ohio, facility. With this step, Joby expands its in-house manufacturing of a critical component and adds to the activities already underway in Dayton, paving the way for at-scale aircraft production ahead of commercial launch.

The prop blades are designed for quiet flight and are built with exacting precision through a complex carbon manufacturing process by a highly skilled team of technicians, both of which are in abundance in Dayton.

Joby’s current iteration, the S4 2.0, has six rotors with five blades each for a total of 30 blades per aircraft. The company anticipates production could reach 15,000 blades per year as it scales the Dayton facility to support mass production of up to 500 aircraft a year.

Joby says it expects the conforming blades – those that meet all FAA requirements for inspection and certification – to be completed in December 2025, and installation on flight test aircraft targeted for next year.

Eric Allison, Chief Product Officer at Joby said, “Dayton gives us the resources, talent, and speed to scale one of the most technically demanding parts of our aircraft. Joby's propeller blades are a key part of what makes our aircraft special – central to its low acoustic profile and the result of a decade of complex engineering.”

Joby will host an event at its Dayton facility on November 10, 2025, to celebrate the start of blade production. The company plans to invite team members, local leaders, and partners to commemorate the site’s opening and shine a spotlight on the region’s role in advancing the next generation of aviation.
