How practical is the Ultra requirement within the US Future Vertical Lift program?
Short answerThe performance appears technically conceivable, but the 2024 assessment doubts that an affordable winged aircraft could be bought in useful numbers.
NotesThe Ultra requirement seeks vertical lift with performance comparable to the C-130J Super Hercules or A400M Atlas. In this 2024 assessment, no practical contender appears ready for the suggested 2025 introduction. A winged aircraft might achieve the performance technically yet cost too much to buy in the quantities needed. An airship perhaps twice the size of Hindenburg could meet the raw lifting requirement, but such a vehicle would be unsuitable for modern combat operations.
