Ah well, just hoped there would be another option, I've almost got a finished design for a proper carrier, so I guess I'll use that.
Also 2 mins was just a guess, I have no idea what firing delays fighters get.
My current fighter design is uses 0. 5x size lasers and is designed to be as fast as possible, to be able to keep up with missiles.
There are some precursors in a nearby system, I think I'm going test them there. If automated PD defences aren't affected by TFT then it shouldn't be a problem.
