For the turret’s guns I’d like to suggest using pulse particle guns as they have a good rate of fire and the have a good damage rate to make any one tailing you think twice. They are about to keep the enemy at bay from a farther distance then the lasers can with only a small differences between the two the pulse particles could do a better job. Also for it’s main guns I haven’t looked at all the guns yet but maybe since it’s coming out of retirement there were some improvements on some weapons that can be put on the Longbow to give it a better change to live through a dogfight with it has no choice but to fight with out costing so much energy slowing down your ability to hold of the swarms of fighter trying to kill you.
