The regional bases could be plan view as they would (mostly) be radar/scanning technology, a transit gate and a small group of assigned protectors the main base (size view) could be where all the work is done and everyone (except local defence forces) is located. Aircraft could transit through the gate to regional bases to get to the closest launch point, so as to minimise transit. It would also mean that the main (side view) base doesn’t need runway connection as the aircraft/drop ship are launched through the gates to local bases with runways etc - your main (side view) base could have a runway structure, except it to is connected via the gate - makes for interest when power/connectivity is disrupted
