They would prefer F-16s, but it depend what the DoD is willing to give them - and they have 30 pilots available for training.
Assuming they started with 3 pilots per aircraft to allow for briefing, debriefing, sleep etc whilst keeping the aircraft on state - then every aircraft lost will have freed up between 2 or 3 pilots, depending if the pilot flying managed to eject or not.
