Did you watch the show last night?
I think it's fair to assume that Galactica has the same armaments as the Pegasus. When Lee brought the Pegasus around to open fire on one of the Basestars, two distinct types of ammunition were fired out of the forward-facing guns. There were long-range simple projectile weapons (like your long-range Flak cannon). However, there were also projectiles of some kind that left a massive smoke trail & also glowed yellow/orange which suggests that they are missiles.
