Ball screws mentioned by Fred are an example of "LOST ART" (hit me with a HASTY GENERALIZATION there). Fairly complex, hell, extremely complex in their metallurgy and screw patterns (wide rectangular with radius and without). Drives and couplings to them just as critical.
You've seen these from your plane's cabin seat if your at the window just aft of the wing. Those screw bodies extending and retracting the wing flaps. These just aren't military applications. Most military applications come to the private sector after all.
All I got for a while.
Good Day, may as well enjoy it.
