Air Combat in the Eldraeverse

So I was looking at The Emperor’s Sword: Some Notes and some thoughts about air combat in the Eldraeverse kept nagging me for days on end, so I decided to ask: How does it work?

“Much like the dedicated air-to-air interceptors (which, as a side note, are usually operated by the Navy as the irritating orbit-to-atmosphere subset of space operations), these are designed to be able to sortie from aerospace cruisers in low forced orbit, as well as from ground airfields should the campaign run long enough for you to have any ground airfields.”

I think I meant to say “How does it work doctrine wise?”
