I'm designing my first PD ships, and I'm hopelessly confused about tracking speed. I can build a beam FC with a tracking of 8,000 km/s when I max it out (my first AS missile has a speed of 10,000, however, so I'd even have trouble defending against my own low-tech ships, not to speak of alien baddies). If the FC can track targets with a speed of up to 8,000, why do I need a turret? And why has the turret its own tracking speed?
BTW, I want the ship to defend the fleet, not only itself. I have a 10cm C2 laser and 24,000-range FC that I could triple in size to bring it up to 72,000. Laser range is 90,000, max tracking range would be 144,000, so if I were attacked by 10,000 km/s missiles, I could fire 9 times (or 4 times when accounting for recharging time). With a bigger 12cm laser (range 120,000) I could fire 12 times (6 incl. recharging) Right?
edit: OK, OK, apparently it's km per second, not per 5-second turn. So the range-90,000 laser would fire once, the other one twice. Correct?
