T'POL: Still, the NX program continued....No, the episode said nothing about NX-Delta being the first to break Warp 3.
ARCHER: Eventually. The Vulcans had us run every simulation they could think of for over a year before they finally admitted the engine would probably work. Eight months after that, Duvall broke Warp Three in the NX-Delta. Five years later we laid the keel for Enterprise. You know the rest.
(Interesting little completely unsupported speculative thought: perhaps the Franklin originally was the NX-Delta?)
Ah, did he say "phase cannons"? I thought I remembered it as "pulsed plasma cannons," but I'm happy to be wrong there. I'll be seeing it again later today or tomorrow, so I'll verify.She supposedly did have phase guns.
This computer display from the Defiant's databanks in "In A Mirror, Darkly" (ENT) says the Wars (plural) ended the year before the UFP was founded and Starfeet was re-chartered, which must be before the Franklin was lost:Why not? It shouldn't take a declared war for the Romulans to fight and defeat UFP ships

And from "Balance Of Terror" (TOS):
SPOCK: Referring to the map on your screens, you will note beyond the moving position of our vessel, a line of Earth outpost stations. Constructed on asteroids, they monitor the Neutral Zone established by treaty after the Earth-Romulan conflict a century ago. As you may recall from your histories, this conflict was fought, by our standards today, with primitive atomic weapons and in primitive space vessels which allowed no quarter, no captives. Nor was there even ship-to-ship visual communication. Therefore, no human, Romulan, or ally has ever seen the other. Earth believes the Romulans to be warlike, cruel, treacherous, and only the Romulans know what they think of Earth. The treaty, set by sub-space radio, established this Neutral Zone, entry into which by either side, would constitute an act of war. The treaty has been unbroken since that time.
