About

Vertical Aerospace is a UK-based eVTOL company developing the VX4 electric air taxi, which completed its piloted transition flight — the technically critical maneuver of transitioning from hovering to forward winged flight — in 2026. This milestone validates the core propulsion architecture and is the hardest technical gate for tiltrotor eVTOL designs. The $800 million conditional funding agreement secured in March 2026, if closed, would be the largest single fundraise in UK aerospace history.
