...Probably nowhere in particular. That is, there was no great requirement to coordinate things, as nothing said or shown was in contradiction anyway, not with the lean VFX that really didn't have enough presence to do any contradicting.
Maybe, but I'm curious if. What did Jefferies think on the matter when he drew it? And writers in the room talk. FX artists and producers. I wonder what they did discuss as the series went along. How many parallel universes of might have beens we could come up with from their discussions, as we can from bits of dialogue, story, images, and literature from the franchise over the decades.
No, those are tubes, as per "The Changeling", where Kirk first orders torps prepared, then picks #2 to be fired. If there only were one tube, his only possible "choice" would be #1 torp in that tube.
I'm inclined to treat that as I do lithium crystals -- an early or creative incongruity.
As long as we don't start fruitlessly arguing that multiple weapons firing simultaneously is better than just one firing (because we can see it isn't, as per the consistent choices by our knowledgeable heroes), there's no real reason to think Kirk's ship didn't have at least six forward torpedo tubes and at least four distinct groupings of phasers (with the forward one quite possibly featuring four banks, as in "Paradise Syndrome", and the others perhaps fewer).
You could argue that firing multiple phasers simultaneously might be fruitless if they're all drawing from the same power source, but torpedoes are another matter, unless you imagine they're armed at the time of need from the same power source.
I think there's plenty of reason to think that Kirks ship didn't have at least six forward torpedo tubes. The Refit and everything that came after suggest a different convention. That ENT retconned TOS a few years after the intro of the Scimitar doesn't fly. Sure there could be fifty hidden phaser banks, torpedo tubes, and Flying Spaghetti Monsters that we just never saw for various reasons, but, meh, I don't buy it.
I think ENT solved most of those problems elegantly enough. And DSC continues the good work, in its own fashion.
Nah, ENT gave us phase pistols (phasing tech) and focused only on them. It left it open for the diehards to conjecture that lower-tech lasers ("They're not lower tech!") were then introduced at whatever point in the timeline that the show itself (Star Trek) wasn't going to present, but the point of ENT to keep the Trek casual fans were comfortable with as they took another trip to the well.
DSC is a parallel universe, or the Prime Universe is ever-changing to meet our needs. It's a TV show, so either work for me.
