Fighters are the escort for the titans as the titans move slower and also house the fighters as there squadron HQ, titans don't fly with fighters or mid ships which there function is the titan's escort, and the titan's role is there base HQ, heavy artillery support, it's command for the fleet, it's the main support for everything else in fleet, its the protector for fleet go near it and it's going to flatten you out right! It cripples mid-ships, pops fighters, that is why a fleet needs to take out a titan, not a single ship lesser than the titan, your out classed.
But there still capable of turning, which is not as of current. titans were never meant to reach top server speeds nor accelerate faster than smaller mid ships, that is what warp drives are for, but they can turn due to horsepower directional thrusting mechanics and no they can't turn like a fighter or mid ship, the turning rate is almost nil on them as of current, regardless of thrust you applied, only applies a vey small portion to directional thrust and acceleration. "Turning rate is nerfed on them".
