"We are talking about ships that are moving at x% of c here. It is not unreasonable for a fleet moving at x% of c to travel to a planet, turn it into glass and move on."
Just to nitpick- *I* am moving at x% of C. It's a low %, but still.
Anyway, SE4 ships don't go FTL. However they are capable of crossing an entire system in one month at max tech, and that is FAST.
