Actually, what will be a very important outcome in air battles in the underground oceans will not be fighter jets, but stuff like VTOL, andHELICOPTERS

This may be a rare time where people actually use them in combat, as most of the time its fighter jets and flying ships. You would need light and tracking of course, but this may be a good time to use helicopters and VTOL aircraft
