Yeah, missiles take a long time to reload, but they always hit if the target stays in range and do a lot of damage. Some weapons take 2 or even 3 turns to reload. The weapon's description in the design window tells you how long. The combat window gives you a countdown turn by turn so
"Run away, Run aeay"

That ruins tech has a reload of 30, and combat Lasts 30 turns, so you get one shot. Make it count. There's a racial tech, the alligence subverter that also is a once per combat weapon. Likewise the fighters have rocket pods, one shot and then they're just cannon fodder
