Ortegas refers to Travis as the first pilot.
Mayweather’s the first in the context of "Broken Bow"; it does not imply that he left the ship at all in all of those 10 years. Even when he was on Enterprise, he was not the only pilot on board. But he is the most recognizable pilot of the NX-01 though, considering he was a member of the senior staff.
The only thing that might suggest Mayweather briefly left Enterprise was his line to Hoshi referring to
her 10 years on the ship. But it's nothing concrete, since he's also referring to Hoshi getting use to living back on Earth on a regular basis, compared to Mayweather being someone used to living in space his whole life as a space boomer.
Built to last? Sure. She was a tough ship, clearly. But during an age of rapid technological advancement, she would have been quickly rendered obsolete, and there comes a point when it's easier and cheaper to build something new, rather than upgrade something old.
For one thing, there probably weren't very many built, making them a rare commodity even when they were top of the line Starships. Why would an exceedingly rare ship that was woefully outdated, still be in active use over 100 years later? At least with ships like the Miranda and the Excelsiors, it can be argued that they built a ton of them and they were likely easy to upgrade. Strange New Worlds also explicitly mentioned that the NX Class ships are "in mothballs."
It’s conjecture that there weren’t many built. We don’t know that for sure. We don’t even know the state of the fleet in the aftermath of the Romulan war, and if ships have to be brought out of mothball to supplement whatever of the fleet is left.
Also, NX class ships used the same S/COMS main computer system as ships In the SNW era did. It would not be that out of date. LCARS isn’t a thing in Starfleet until TFF.
Also, in SNW, the NX class ships are in mothballs until they need a story based around an NX class ship.
So what? So do a lot of people.
If the NX-01 was simply remembered as Archer's Enterprise, Riker would have said so.
For all we know, the XCV-330 was a one off prototype that never amounted to much of anything. The NX-01 was the first Starship Enterprise that did anything significant.
It must have amounted to something. Since paintings of it were all over the place. It's an admired and revered ship.
You kind of have to take into account the fact that Enterprise didn't exist yet. It's just a reality of production. Regardless, you can simply interpret Sisko as saying the first Federation Starship Enterprise.
And you also have to take into account that it’s all the same continuity. And that even if Sisko makes the distinction of the first Federation Starship Enteprise, it's not the first Enterprise. The XCV-330 is, and has been established since TMP. Which predates both DS9 and ENT.
Same as above. Just a good old-fashioned retcon. Though, I suppose if you need some kinda head canon explanation, you could simply say that the first Federation Starship was the USS DAUNTLESS NCC-01, and that the Voyager crew assumed the ship was named after that historic vessel.
I like my headcanon as it is. They rechristened the NX-01 as the Dauntless, and it continued to see service under a different captain.
Even so, he was the most competent person on that crew. Even if promotions were fewer because there was no LTJG or LCDR ranks, he still rated some sort of acknowledgement.
He got a middle school gym in Colombia named after him. It’s not a whole school like Archer or Cochrane got, but it’s something.
It's was absolutely stupid that no one on the NX-01 crew was promoted by 2161. Especially considering that a war had just taken place. One of the more stupid parts of TATV.
And no one looked different. No uniform changes, no aging, no hairstyle changes, no facial hair... it was appalling laziness on their part.
It is shocking that they never simply took the Intrepid, Columbia and NX Project uniforms, switch the patches to the other arm and add epaulets like they did with the Enterprise uniform. Just shocking that it never crossed their minds to do so. But what’s done is done. Until someone can be bothered to make a sequel to TATV.
As I mentioned before, there's no correlation between the fake Dauntless NX-01-A from VOY, and the NX-01 Enterprise. Here's why:
1. Just because the fake Dauntless had a registry of NX-01-A does not mean that there was once a Dauntless with the registry NX-01. We have no idea about Arturis's logic with coming up with that registry, as he had no knowledge about Starfleet and their registry schemes.
2. But let's play devil's advocate anyway, and assume that somehow Arturis was aware of that. Just because none of the Voyager crew question the Dauntless's registry still doesn't mean that it correlates to a past ship named Dauntless with a registry of NX-01. For all they knew, while they were gone Starfleet reset the registry scheme, and the Dauntless was the first ship with this new registry.
3. But most of all...the Earth ship Enterprise's registry isn't the same as Starfleet's registry scheme. Because the "NX" in NX-01 is the ship's class, while "NX" in a Starfleet registry scheme denotes an experimental prototype. Yes, the Enterprise was a prototype as well, but the next ship in the class wasn't 'NCC-02,' it was NX-02. So there's no reason to assume that the Federation Starfleet's first ship was the Dauntless NX-01, or even if it was, there's no reason to assume that the Enterprise NX-01 was renamed the Dauntless and recommissioned. And if Dave Blass is to be believed, then the Enterprise NX-01 still had its name unchanged by the 25th century.
1. The crew could have still checked their own databases and verified. Would have taken all of 10 seconds.
2. Maybe. But if anyone in Starfleet should question what's in front of them, it's a science ship like Voyager.
3. It means whatever the writers want it to mean.
For example, the registry NC can refer to a shuttlepod, like in “Home”, or a Class J civilian transport like in “The Way to Eden”
If the writers wanted NX to have a double meaning as both a ship class and for experimental ships, that’s their right.
