Or Schriever Air Force Base. Since this is going to grow out of the current Air Force Space Command, and the 50th Space Wing has long been headquartered at Schriever, and there is plenty of room to grow out there, no other missions to impede or interfere with (ie the Air Force could eventually give SAFB over to a separate Space Force without losing anything else)... I’ll bet you it goes to Colorado.
