I've always found it too coincidental that throughout the run of the show whenever the Enterprise encountered another Starfleet ship it was always of it's own class.
While it seems like over the years there has been debate by fans over how many of the original Constitution Class ships were built and I've seen so many different sources sited, but if one was to go by the best canon evidence in "Tomorrow is Yesterday" that the number is twelve, including the Enterprise, that makes them a very rare commodity. Given such a small percentage combined with the size of the space Starfleet is operating in or exploring and the distances needed to travel, one would imagine these top-of-the line Starships would be assigned in different, distant sectors and far-flung from each other. As a result its easy to image that the times one of them would be in the same sector as one of it's counterparts during the course of a multi-year mission would be an uncommon event. Any rare rendezvous would be planned in advance (like in "Obsession") and a chance encounter with each other almost unheard of.
Yet throughout TOS they seemed to be ubiquitous in the galaxy and were the only type of Federation starship we ever saw. Whether it be responding to another Starfleet ship in peril ("The Doomsday Machine", "The Omega Glory", "The Tholian Web" "The Immunity Syndrome") or taking part in a task force with other vessels ("The Ultimate Computer", "Errand of Mercy - remastered), they were always another Connie leading us to believe they were always patrolling and exploring in the same general area.
The original version of "Errand of Mercy" allowed some leeway, since the Federation fleet facing off with the Klingon one was never shown thus it was easy to imagine it consisting of some sort of hastily organized task force of different types of ships like destroyers, frigates, light cruisers, etc. with maybe one other Constitution at the most. Yet remastered TOS (which I've always been lukewarm about) retro-conned this by showing the fleets consisting of identical Federation and Klingon ships and thus destroyed this theory and making one have to accept the unbelievable premise that Starfleet was able to send at least half the amount of their best starships to Organia on short notice.
Obviously the real-life reason is that by using existing shots of the Enterprise model and superimposing them together the producers could show the Enterprise encountering another Federation vessel without having to build a new, different type of model. To say nothing of having to design interior sets for the new ship and maybe even different uniform designs.
However, since the whole point of fandom (and thus this forum) is to speculate on an in-universe explanation for discrepancies, what might that be? How can so many of Starfleet's elite ships be always within practically hailing distance of each other so often when they are supposed to be so few in number?
