The prototype S4-T made its first flight at Marina, California, on Nov. 7, and on April 16 Joby posted a video on YouTube showing the aircraft taking off vertically and rapidly transitioning to wingborne horizontal flight.

Joby and L3Harris are proposing the S4-T as a Group 4+ uncrewed aircraft system (UAS) for three Army missions: reconnaissance, surveillance and target acquisition, advanced teaming, and launched effects, says Robert Smith, director of intelligence, surveillance, and reconnaissance (ISR) business development at L3Harris.
