It wasn't just retained knowledge, he still has a connection to the Collective that lets him hear their thoughts. So he could hear them saying "Aw crap, these new weapons made our shields fail in this one spot and if we get hit there too much we'll blow!"
This. I doubt the Ent-E could have taken the cube down by itself, even with the weak spot. There was a lot of firepower on display during those seconds after Picard said "Fire."^ Right. And it wasn't just the Enterprise E that destroyed the cube. Picard sent the location of it's weak points to all that remained of the fleet, which then launched a simultaneous attack.
Re: the Bozeman (not quoting here cause several people commented on this, and this post is gonna be huge as it is)... personally, I don't think there is any way that the Soyuz-class Bozeman was still in service after TNG "Cause and Effect." Geordi said that the CLASS had been retired for 80 years as of that ep. Starfleet's upgrade and refit capabilities have been shown to be quite impressive (see: Excelsior and Miranda), but still, for any class, there would come a time when you just couldn't keep it current anymore, and had to retire it. Since the Soyuz had been retired 80 years prior, it was obviously well past that point; there's no way it could just be "upgraded" to be viable in the late 2360's or beyond. I think the Bozeman referenced in FC is a newer ship class, named in honor of the Soyuz class ship and given to Bateson once he was brought up to speed.
Yeah, and it's been well-acknowledged IIRC that the main (only, really) reason we didn't see any Sovereigns in DS9 was that the producers didn't want "the movie ship" showing up in the current TV show, i.e. entirely out-of universe reasons.I tend to think we just didn't see many Defiants because of a combination of would've been confusing to the viewer and they were on other fronts. Maybe the 7th Fleet had a lot of Defiants and other modern ships?
I agree with this view. We did after all only get a quite limited view of the Dominion War and even the battles we did see we mostly only saw what was going on around the Defiant. Even the largest Fed fleet we saw, that in Operation Return, who many of the six hundred vessels in the fleet did we actually see on screen? There is still enough wiggle room that there could have been more than just one Defiant class vessel in Operation Return or at Chin'toka or Cardassia.
Pretty much the same view I take with the Sovereign class and the Enterprise-E, even though we didn't seem them in the war I like to believe they took part.
Registry numbers aren't always chronological by class. The Oberth-class is older than Excelsior, yet there are some Oberths that have higher registries than many Excelsiors or Ambassadors, due to being built later (the Pegasus, for example, was NCC-53847). Same deal occurs with Excelsior vs. Ambassador. And most telling, the Promethus from "Message in a Bottle", which was clearly a brand-new experimental prototype at that time, was NX-59650.No Akira Steamrunner and Saber were older vessels.
Akira and Saber were register in the 60,000's
and Steamrunner int he 52,000's
Defenseless? Every one of the many ships which flew alongside the Defiant and were still intact (and dishing out damage) after the defense satellites were shut down would disagree with that. As for "far superior," the fact that the Galaxy was mass-produced to the point where there were "wings" of them, and the fact that post-Odyssey, the only thing the Galaxy was ever seen doing on-screen was steamrolling anything that got in its way would seem to dispute that.While Defiant was far superior to the Galaxy Class Starship. As seen in Chintoka as Defiant's shields held repeatedly against the Dominion defense satellites and all other ships were defenseless against them.
And those classes couldn't be refitted in the same way the Lakota was... why?Lakota was said to be refitted.
Steamrunners, Akiras and Saberes are all inferior because they either have 3 or less phaser arrays and extremely limited firing arcs and no torpedoes.
Additional phaser arrays have been added to existing designs before (Venture in "Way of the Warrior" vs. original Galaxy-class).
They can barely defend themselves. That explains why they were sent to fight the Borg, and why several of them survived the entire battle to still be intact after the cube was destroyed.These ships are inferrior in just about everyone. They can barely defend themselves. Even the Nova Class has at least 8 phaser arrays.

You've identified other parts of your posts as speculation or based on non-canon, so I assume this is as well, but still... "can barely defend themselves"? Seriously?
The way your posts are written, it's sometimes hard to tell when you ARE "just speculating" vs. stating something as canon, established in-universe "fact".
We hardly ever got a clear look at ANY Starfleet ships firing during most Dominion War battles, except the Defiant, the occasional Galaxy, an Excelsior or Miranda here and there... it was an oddity of the way the Dominion War battles were filmed.Lets say they did design the Akira with the "torpedo boat" mentality. It's not that way anymore. In full battle mode this vessel has never been seen firing from those launchers all out. My estimation is they've been pulled. These ships are relics of the early 24th century...designed bubble gum, if you will.
More than sixteen?!It's not the process it's the space-frame.
The question is what do you have to work with. Excelsior has more than 16 phaser arrays and dual fore and aft torpedo launchers and very maneuverable on impulse.

First: says who?
Second: that's WAY more than any Starfleet ship would ever need (considering that the Galaxy is the biggest one ever produced, and it has more than enough with its twelve arrays). The Sovereign is supposed to have sixteen post-refit, isn't it? That, too, is overkill. But where's the evidence that the freaking Excelsior has that many, let alone MORE?
And they can be fired in multiple directions, like an array. The point of them, whatever you want to call them, seems to be to give the Defiant an additional weapon that DOESN'T have the limitations of the pulse phaser cannons, for when their enemies slip behind them. Someone in this thread (I can't remember who... the thread is kind of all over the place and really, I probably shouldn't have even bothered with this post, but I'm at work and boredI wouldn't call them arrays. More like turrets and Defiant has one in the nose and one on top of the bridge.

Says who?I don't think so, Enterprise was refited from the Ground up
Not sure what you mean by this... further ships of a class are constructed at roughly the same time as the prototype? If that IS what you mean, that certainly doesn't seem to be how things work in Trek.and the class ship is likely to have the same issues. Most ships are constructed at the same time.
One last thing on the Sovereign being "a failure": they don't make Enterprise's members of failed classes.
Having said all that... I kinda don't get this thread's original topic (that didn't stop me from writing a wall of text about all the various tangents, though.

And Cyke101 is right: there is a TON of speculation involved here, and various non-canon/semi-canon sources contradict each other, quite often.
