We don’t need the bureaucracy and unnecessary overhead for a Space Force. Keep it under the aegis of the Air Force, I say.
We currently have a lot of bureaucratic overhead duplication between the space systems R&D, procurement and operations activities of the Air Force, Navy, Intelligence Community, organizations within the DOD that lease commercial satellite capacity, organizations that buy commercial imagery, and aspects of NOAA.
Integrating all of this into a Space Force should reduce overhead, increase efficiency, reduce operational duplication, and eliminate jockeying between services for control of various space capabilities and the associated paralysis and delays. It should lead to quicker decision making rather than having six competing committees "studying" things for years and then nothing happens.
But if the Space Force has old-guard leadership, it isn't going to work. The key will be to put a non-nonsense leader at the top of this thing, preferably from industry, but not one of the Boeing, Lockheed, or Northrop Grumman people who have helped preserve and profit from the ineffective current structure.
