In addition, since enemy missiles fly through space, NORAD was involved with space. The fact that NORAD had no ability to do anything about the missiles, but could deal to some extent with aircraft, does not change the picture: NORAD was part of Space Command.

Now NORAD's role has been appropriately clarified by its integration with the rest of homeland defense into Northern Command. Indeed, NORAD's old boss, CINC Space, has been named commander of Northern Command, rounding things out. The problem is that now CINC Space and NORAD have both been separated from Space Command, leaving behind
an entity that is losing its emerging identity to STRATCOM. The joint restructuring is intensified by the situation in the Air Force itself.

There is an entity within the Air Force known as Space and Missile Command that consists of all the ICBMs, their silos and the men and women trained to operate them. While linked to Space Command inside the Air Force in the event of war they are operated by Strategic Command. STRATCOM owns all U.S. nuclear strike capabilities and, in the event of war, it owns the Navy's missile submarines and the Air Force's missiles as well.
Air Force Space Command is linked to Missile Command because missiles fly through space. But the real function of the Air Force and Navy Space Commands is to operate the satellites that enable warfare.

They operate communications satellites, remote sensing satellites and the critical NAVSTAR constellation of satellites called Global Positioning Systems, which enables B-2s to launch JDAMS, U.S. Army Special Forces teams to orient themselves and uncountable other civilian and military systems to operate.
