..operating the intermediate ship classes up to the NX class. What were they used for? Short range exploration and survey (pretty different than long range), coast guard type duties, testing the technology.
Not much exploring to be done at short range - the Vulcans had already been everywhere. We never heard of an exploration mission, either, or of a skipper who would have had qualifications of that sort; they put their warp 5 expert in command of the exploration mission instead.
Not much coast-guarding, either, it seems: no UESF seemed to ever have challenged a pirate vessel, for example. And the idea of search-and-rescue would be quite ludicrous anywhere outside the Sol system if it took the SAR ship months or years to arrive...
What the
Intrepid and her two companions did do was defensive combat, seeming capital ship against capital ship.
They aren't really heavily armed either.
They defeated their Klingon counterparts. I'd say that's pretty high praise if one wants to define "heavily armed" or "combat ready".
Enterprise had state of the art technology and it only had simple torpedoes at the beginning.
It was explicated that she left port before being completed, though. Her big phase guns were ready - it's just that only one (plus parts for two more) was aboard, and the rest were waiting back in the Sol system for Archer to finish his unscheduled ferry mission.
There wasn't much to suggest that the phase cannon would be a novel weapon never installed elsewhere before; Reed and Tucker did know their way around one, and the ships from "The Expanse" had this weaponry as well and may have carried it for much longer than two years for all we know. What was new was the overload mode that our heroes discovered, with a bit of help from nasty aliens.
Or they were jointly operating in the sense that one operated maned ships, the other unmaned spacecraft.
Hmm... That works fine, too. Good idea.
For supposed military personel (who after all, spend most of their time training and training for fighting) they were also pretty bumbling in their fighting at the start of the series.
Odds are they left their gunners and other specialists ashore in "Broken Bow", though, just like Reed complained they left their guns and ammo. The most "militant" guy aboard was called Armory Officer, and was needed down below in the torp room, yet the ship did have a requirement and a bridge console for what later Trek would call a Tactical Officer.
The two-year mission we saw was never supposed to be the one the ship was designed for. Archer simply decided not to return home after his ferry mission, and had to make do with limited resources as a consequence. When he did get home, her ship became a rather more powerful fighting machine - but only by receiving ordnance that apparently already was slated to go there, since the gunports had always been there on the hull. And the sister ship
Columbia was specifically said to be receiving an even heavier, nonstandard weapons fit as the result of the S1&2 experiences, so the one on the
Enterprise could well have been standard despite being heavy.
