Another first for the program:
A Lockheed Martin F-35B Short Takeoff/Vertical Landing (STOVL) Lightning II test aircraft recently completed the first-ever Vertical Takeoff (VTO) on May 10.
VTOs are one of the many capabilities required for the fielding an F-35B aircraft. While not a combat capability, VTOs are required for repositioning of the STOVL in environments where a jet could not perform a short takeoff. In these cases, the jet, with a limited amount of fuel, would execute a VTO to travel a short distance.
