In the ATV yesterday, I believe you mentioned that while the ship has four drones, you can only use two drones at a time because there are two stations?

Yes. Two in active control of them. When you stop using them, I'm not fully sure on where our drone gameplay is, but I imagine at the very minimum they're just going to remain in place, but you might be able to leave it in a sort of pre-programmed flying around situation. Because they can only do one function, you load them up how you want, send your refueling one out. That's doing refueling. Whilst that's doing that, jump on to the other one, start doing some rearming.
