This may have been asked before, but in in Khan we see that photon torpedoes need to be physically loaded into the breach which is a detail that Nick Meyer probably wanted to cite from Hornblower canon crews loading up for broadsides. However, the torpedo area on the Reliant is physically detached from the main hull. This would mean that the torpedo crew would be isolated from the rest of the ship and not able to go to and fro save for transporters or pods. I never thought about this back in the day, but for whatever reason it's bugging me now. We never see crews loading torpedoes on the Reliant so it's possible that it's a newer torpedo delivery system that doesn't need crews. This would jive with the fact Khan is running the Reliant on a skeleton crew of pirates. Has this been rationalized over the years?
