Swallows is a tier-3 missile, it's one of the two missiles you can choose at tier-3...it sends out 3 missiles slightly faster than the other missile (Falcon?), which is 2 missiles, but they're more powerful than Swallows. If you look at it...they're equal I think...except for the speed they're fired at.
