The U.S. Air Force has wrapped up the airworthiness evaluation for the design of Joby Aviation's S4 aircraft as part of the Agility Prime effort. USAF may carry out flight tests for the aircraft once it completes all phases of the airworthiness process, the service branch said Wednesday.
The service branch will use the flight tests to yield data that may support S4's Federal Aviation Administration certification as well as evaluate the aircraft's utility in various operations such as medical evacuation and disaster response activities.
Joby and BETA Technologies joined Agility Prime in February as its initial partner companies.
The Air Force has announced its intent to explore other uses cases and deploy organic resupply buses in 2023. The military service will also launch the Space Prime at an undisclosed date.
