[AWP]

Folks they want will still sign up.
My take, and @AWP can chime in, it takes 3+ years to get folks up too speed. So you get less than a years productivity before they separate.
8 year enlistment will cut down on turnover.

Agree. 8 years is a good ROI for the country and frankly for the person. The TS/SCI and the stuff you'll do will make someone a very attractive candidate in the private sector, especially with a STEM degree.

It takes the Army over a year to develop a satellite controller. (25S with a...1C or something ASI) I'm not sure about the Space Force/ USAF version.
