Archer didn't seem to have any problem with Enterprise being Earth's one instrument of vengeance during the third season, though. And Starfleet had no problem sending Archer to command this mission of vengeance, even though Archer had no combat merits we'd know of and could have been replaced at the drop of a hat, especially if his bosses felt he might not be happy with having a MACO contingent aboard.
That Archer still had something to prove though, both with his father’s warp engine, and with humanity’s standing with the Vulcans. By the time of the Romulan War starting though:
- His father’s engine is being mass produced to other NX ships (starting with Columbia) and its is known it can reach Warp 5.2
- The Vulcans have gone through a reformation and stopped being dicks to humans and allowing them to explore without their supervision
- Archer has likely grown attached to his crew more than he is attached to the ship itself
- Archer may not have had a desire to see another mission like the Xindi again
From Starfleet’s perspective for choosing Archer for the Xindi mission:
- T’Pol would be seen as a representative of Vulcan leading a human mission, and would likely have her methods questioned by members of the crew
- Trip would have blown up everything in sight due to his emotional state at the time
- Reed, Phlox, Mayweather, Sato, have no command experience
- Their other choice to command the NX-01, A.G Robinson, died in a climbing accident a few months before
- Erika Hernandez had no experience going on deep space missions
- Soval, prior to “Cease Fire” hadn’t fired a weapon in 50 years, and would be another representative of Vulcan leading humans, and would face the same problems as T’Pol
- I don’t know if Admiral Forrest, or any admiral for that matter had any combat experience
- MACO’s aren’t known for deep space missions either
We don't even know if the MACO used phasers at all. Their weapons are never given a name, and they don't demonstrate the stun setting that Tucker thinks is worth specifically pointing out to Archer when he introduces the all-new phaser personal armament in "Broken Bow". For all we know, as of the third season of ENT, the Military still conservatively relies on the older "plasma gun" technology of which the EM-33 pistol supposedly was an example.
The idea is that MACO weapons are more powerful than Starfleet weapons. And is to be expected, since it is a MACO’s area of expertise. They just didn’t loan any to Starfleet for "political" reasons.
If the Xindi mission was a Starfleet one, I see no reason for the Romulan one not to be. Starfleet is the only known Earth force that fights space battles.
That we know of.
It did so against the Xindi, and against the Klingons. Indeed, Starfleet supposedly did nothing but fight until it got its first-ever exploration asset, the NX-01...
Maybe the Xindi mission – and the NX-01 return as a badly damaged vessel – was a wakeup call. The Starfleet from before that mission was naïve, and dare I say, full of hubris.
As part of an alliance, yes. Would an alliance call for separate flagships on a species basis?
Based upon what was seen in the Dominion War with the Federation, Klingons and Romulans, yes they would.
...One wonders if this particular
Defiant didn't come from a slightly parallel timeline, then.
That does open up the possibility that ENT is from a parallel timeline as well.
That's a good one! (Also, who'd care to learn when this Jim Kirk sap was born when he supposedly was a nobody when the Defiant hopped universes? Why not list the birth dates of people actually considered great at the time, such as Tracey or Pike?)
If its a parallel timeline, do Tracey and Pike even exist?
Agreed. One very much wonders, then, why the ship in "Balance of Terror" was crewed... Wouldn't this be the one mission where the presence of a crew would be a completely unacceptable risk?
Based upon the uniforms that the Romulans were wearing, in “Balance of Terror,” “The Enterprise Incident,” and
The Undiscovered Country – which are very different from the uniforms worn in both ENT and TNG/DS9 - I think there were some significant reforms that occurred behind the scene on Romulus. That includes visual contact with other species, regardless if they are friend or foe.
