Single stage rocket launchers do not exist.

Neither do the pressure-fed launchers you're talking about.

Does it mean that the spent first stage is dropped near
Phoenix, Arizona...

No, its pilot turns it around and flies it back to base. Or, possibly,
glides it down to a landing at some suitable airstrip, from which it is
trucked or flown back to Mojave, although that's rather less convenient.
What part of "horizontal-takeoff-horizontal-landing only" is so hard for
you to grasp?

Your pressure-fed artillery rockets will *never* operate out of Mojave,
and it's got nothing to do with where the pieces falling off would land.
