I'm trying to remember if dorsal phasers were ever shown firing on a Constitution class starship. In the series they seemed to be emitting from the dome on the ventral side of the saucer. I don't remember even seeing phaser firing from the dorsal side of the saucer in the movies. In the movies, what appear to be dorsal emitters are shown on the saucer but never fired (except maybe in TSFS). In Enterprise's In A Mirror Darkly aft phasers were shown firing, but those couldn't provide the c0verage phasers on the dorsal side of the saucer would. So did the TV Constitution ever fire dorsal phasers? If not, is it canon that, before their upgrade in the movies, there were no dorsal phasers?
