President Joe Biden has decided that the headquarters of US Space Command will remain in Colorado and not move to Alabama, two US officials told CNN on Monday, reversing a decision by then-President Donald Trump.
SPACECOM is a unified command that has its origins in the 1980s. It is entirely necessary and handles real things including military satellites and missile defense.
B) Space Force isn't anything new. It is doing the same projects it was doing under the Air Force, with the same budget it had under the Air Force, with mostly the same officers/leadership it had under the Air Force.
C) You can debate about whether a trillion dollar defense industry is ridiculous. That's valid. But if you assume we need a defense industry that large, then the work the Space Force does (again, which hasn't changed since it was the Air Force) is absolutely necessary in the modern era.
