I already told you. Canonically, we saw non-Enterprise personnel wearing the arrowhead in "Court-Martial" (the officers in the bar who gave Kirk the cold shoulder -- that would've been insubordinate if they'd been part of his crew) and "The Menagerie" (a Starbase 11 staffer in the background). The memo merely provides context for the canonical evidence.
I tried to look up the uses of insignia on pre-TMP Starfleet (prime universe), and this's what I found
ships with the Enterprise arrowhead
-
U.S.S. Ariel (registry unknown) (“The Eye of the Beholder” [TAS]): A TOS era ship
- Unnamed ship of the hostile officers (“Court Martial” [TOS]): A TOS era ship
Ships with a variation of the Enterprise arrowhead
-
Friendship 1 (“Friendship One” [VOY]): A rep-TOS, pre-Starfleet, pre-United Earth (at least in full) UESPA probe with a United Nations or New United Nations emblem that resembled the future
Enterprise arrowhead.
-
U.S.S. Franklin NX-326 (
Star Trek Beyond): A pre-TOS ship, who’s unique mission patch included a sider version of the arrowhead.
-
U.S.S. Kelvin NCC-0514 (
Star Trek [2009]): A pre-TOS ship, with an unique hollow version of the arrowhead
Ships without the Enterprise arrowhead
-
Bonaventure 1028NCC (“The Time Trap” [TAS]): A pre-TOS ship
-
U.S.S. Antares NCC-501 ("Charlie X" [TOS]): A TOS era ship
-
U.S.S. Constellation NCC-1017 (“The Doomsday Machine” [TOS]): A TOS era ship
-
U.S.S. Defiant NCC-1764 (“In a Mirror, Darkly, Parts I and II” [ENT]): A TOS ship [retconned from the
Enterprise arrowhead in “The Tholian Web” (TOS)]
-
U.S.S. Exter NCC-1672 (“The Omega Glory” [TOS]): A TOS era ship
-
U.S.S. Lexington NCC-1709 (“The Ultimate Computer” [TOS]): A TOS era ship [possibly; Commodore Wesley, the CO, had the “starburst” emblem used for staircase personal]
-
U.S.S. Huron NCC-F1913 (“The Pirates of Orion” [TAS]): A TOS era ship
- Epsilon IX (
Star Trek - The Motion Picture): A TOS era facility [also operating when the arrowhead was definitely the universal Starfleet emblem in the prime universe]
- Starbase 11 personal (“The Menagerie, Part I,” “Court Martial” [TOS]): A TOS facility [that metal starburst emblem thing]
- Starbase 10 personal (“The Deadly Years” [TOS]): A TOS facility [it also looks like a different one than the Starbase 11, if I recall correctly[/quote]
So, we have two minor instances with the arrowhead being used outside of the
Enterprise, two of a unique patch using the arrowhead in its own design (I don't think
Friendship 1's should count, since that's obviously a non-Starfleet emblem that presumably influenced the later arrowhead, regardless of what theory you subscribe to) against
ten instances where we see unique patches for different ships and assignments.
So, it's two against twelve. At best, if we count the arrowhead variations with the exact copies, it's four to ten. Either way, the "unique mission patch theory is in the majority and all the examples against it make more sense as minor costuming errors. So, can you understand why I don't think your position is a very viable one? There's not only overwhelming evidence against it, but the only examples usable to support it are the weakest in the whole discussion.
I think it's more just that the makers of IaMD probably didn't realize that they were actually arrowhead patches. The memo hadn't surfaced yet, and the myth that each ship had its own insignia had been part of fan lore for decades.
It's not a myth. There are ten to twelve examples of it. We just didn't know that that was a retcon of a non-canon idea the filmmakers had.
Besides, there's the preponderance of later evidence about the pre-TOS use of the insignia -- the Friendship 1 UESPA emblem, the 22nd-century rating patches, the Kelvin. It's clear that the arrowhead was originally the UESPA emblem and was never unique to a single ship. So it's illogical to assume that Starfleet temporarily switched to using a different insignia for every single ship and then went back to using the arrowhead exclusively. It's simpler to conclude that it was always used fleetwide, but that there were other variant patches in use alongside it for a time.
The
Franklin and
Kelvin's patches are different enough I would count them as separate patches, IMHO. I don't have a problem with Starfleet reusing variations of the arrowhead over time, esp. as there are decades in between each ship getting there's.
Yes, but that's story. Keeping the story and the characters consistent is one thing. Obsessing on making sure every single prop and costume looks exactly like it did 50 years ago is not necessary for story consistency. Look at comic books. When a new artist takes over a book, they don't slavishly copy their predecessor's art style. They bring in their own distinctive way of drawing the characters and the costumes. John Romita, Jr.'s Peter Parker does not look like John Romita, Sr.'s Peter Parker, or Steve Ditko's Peter Parker, or Ross Andru's or John Byrne's or Humberto Ramos's. But we accept that they're the same character even though the artists interpret them differently. We accept that the Spider-Man costume is the same even if different artists draw the eyes or the logo at different sizes. And so on.
I don't know. A new artist can be really jarring, esp. if they're trying to go for a different style.
So when it comes to redesigns of alien makeups or Starfleet technology, we don't have to assume it's actually changed in-universe, any more than we have to assume that Saavik got massive cosmetic surgery right after Spock's funeral. Some visual changes are merely differences in interpretation. We're not watching a documentary broadcast from a parallel universe, we're watching an artistic interpretation of a story. And elements of the interpretation can be tweaked without changing the underlying narrative.
Fair enough. But I'm looking at it as what can be explained in universe and what we just suspend disbelief on.
