Well if the Shivan Commanders have sense they'll deploy the entire Air Wing once they're under an attack. Also, the Sath's ability to do a 180 is dictated by its engines, not its fighterbay. And believe me, I once tried to FRED a mission to explore different kind of assaults on the Sathanas, the ones that involved disabling it got bogged down quickly because taking out the engines on that thing is HARD. Seriously, you have got to defang the Forward Beam Cannons or you won't stand a chance otherwise.
Trying to stay in its blind spot won't work forever because you'll have to be simultaneously hitting the Fighterbay, and unless you destroy it instantly, you're going to be facing whatever it's got available on the flightdeck very quickly.
Seriously, it's defang or die for anyone going up against the Jug.
