Well, if missiles had theoretically inf max speeds, and are only limited by acceleration (mostly referring more to torpedoes than srms and such), it would mean a lot more
I do know that stuff like bombs are purely ship momentum (and absolutely HILARIOUS amounts of damage in a bombing run..)
Doing a test personally, it looks like reaper torpedoes are a lot faster than the atrophos torpedoes - When fired from a hyperion going max speed, the reaper accelerates on leaving the hyperion, whereas atrophos SLOW DOWN....
