Wow, newtype alpha, that's more or less what I'd been noodling around with myself. Very well said!
The weirdness of the Federation economy, and the optimism of the premise of Trek, would seem to preclude the idea of Eisenhower's military-industrial complex existing in the 23rd century, but as you say, the hardline right-wing in Cartwright and company is clearly still there. All that talk of 'dismantling Starfleet' in TUC combined with the pre-established tensions with the Klingons and the re-emerged Romulans was clearly meant to be a parallel to the U.S.-Soviet Cold War, so why not also assume that the Federation had also developed a battle fleet that was just waiting for war to break out? I particularly like your theorizing with the Klingons and Romulans in the post-TUC era.
I'm not sure that I agree that the 24th century 'reinvention' of Starfleet need to be quite so wholesale, as clearly exploratory missions were a part of the ENT and TOS Starfleet's directives, but I do agree that there was a reinvention of sorts, in some ways more of a back-to-basics reversion to the 22nd century ideals, now with the applied technology of the 24th.
Is it obvious now that I'm sold on the 23rd and 22nd century Starfleets having built dedicated warships?
While I'll avoid specific classes (since there are so many good designs from over the yeras to pick through), I envision the following. Since the founding of the Federation, Starfleet had been interally conflicted by those who maintained that it remain an organization of peace as prior to the Romulan War, and those who maintained that the War proved its primary obligation was militaristic. As the decades passed, this contention grew. By 2260, in addition to their various multi-role cruisers, Starfleet had refit the fleet across the board to match Constitution specifications and commissioned matching new dreadnoughts (perhaps six to twelve) and battleships (I'd say no more than six) in anticipation of war with the Klingons, in addtion to various through deck cruisers and destroyers, expanding Starfleet significantly. The re-emergence of the Romulans and alliance with the Klingons furthered Federation conviction that war was inevitable. Over the subsequent decades, enormous resources were allocated and spent to maintain, update, and refit these forces, as well as commissioning new ship classes and expanding existing ones.
As a result of the 2290s detente and the subsequent treaties with the Klingons, Starfleet ended up having to decommission most of the dedicated war fleet it had built up for decades, and began changes to focus more on scientific programs. It seemed that the science-oriented side had won, but a compromise was reach in developing the Explorer type starship, a ship so large and so powerful that while not being a dedicated warship, and thus having something to do in peace time and not violating treaty, it would in the event of a war become the battleships that Starfleet had just been forced to decommission. Beginning with the Ambassador and subsequently the Galaxy class, these ships became the 'dual purpose' ships that Starfleet realized it should have been building all along. Only when the Borg threat emerged would Starfleet feel the need to commission a series of war-oriented ships beginning with the Defiant.
Presumably there are always scientific, exploratory, and support missions to be undertaken, there may not always be wars to fight. There's enough overlap in the basic design requirements for the two (such as torpedo launchers for probes) that even a vessel designed principally for combat could fulfill other roles.
If Starfleet does have dedicated warships I suspect they're smaller vessels for patrol/escort duty, less powerful in a combat role than the larger starships but more efficient. Half the strength, one quarter the tonnage/cost and such.
But, and perhaps this is a bad comparison in general, consider the fleet maintained by the United States Navy. Its ships and fleet makeup are substantially bigger than is really necessary to perform the duties it is required to perform outside of war.
And for that reason, the U.S. Navy is ridiculously over-priced and laughably inefficient. Most of its hardware was designed to fight a war that will never happen against an enemy that no longer exists using weapons that are already obsolete using tactics that have never been tested in the theatre.
I don't see the Federation as possessing some kind of self-serving notoriously corrupt military industrial complex. Actually, I believe the move away from dedicated warships (and the controversy around the Defiant project, for that matter) is a reaction to precisely this kind of development.
Follow this fictional history: for fifty years, Starfleet built up more and more overtly military hardware to deal with the threat of the Klingon Empire. The Klingons, for their part, built up their military the same way. Then Praxis exploded and the Klingons realized they had spent so much money on their military that they couldn't deal with a simple natural disaster properly (coughHurricaneKatrinacough) and they needed to reorganize. This meant the end of hostilities with the Klingons, and it suddenly left Starfleet holding a bill for a huge and expensive battle fleet that it would never have a chance to use.
In TUC, we have assholes like Admiral Cartwright and such who understand that the organization they created is about to be gutted because its principal mission--fighting the Klingons--has ceased to exist. Even Valeris describes her actions as "saving Starfleet," as if the Klingon threat is Starfleet's only reason to exist! (the Federation seemed to be on surprisingly good terms with the Romulans at the time...).
We don't know what happened after TUC, but in TNG we get a hint that there was some trouble with the Romulans, more tension with the Klingons and later some skirmishes with the Cardassians... none of which approached the scale and intensity of the 23rd century cold war. We can infer from this that within the Klingon Empire some type of cultural revolution occurred, probably a revolt by Khaless fundamentalists seeking to return the Empire to the "true war of the warrior" or some crap like that. This fundamentally changed the political landscape of the High Council, paving the way for a more feudal type of government where the high council retained no real power except the ability to organize the many houses and the ships they controlled to make war against their enemies. From this point on, then, Klingons only fight for personal reasons, with (until Gowron) none of the grand political power plays for the "Glory of the Empire."
With this power dynamic--and since Cartwright's people fail to start the war that had taken over their reason for being--Starfleet had to reinvent itself in order to remain relevant. First, the lack of a mutual enemy lead to the Romulans dusting off their old rivalries, and since the Romulans rarely come out in force, a greater emphasis was put on counterintelligence and electronic warfare (with the main computer completely taking over ship's communications on most vessels). Second, Starfleet either absorbed or subcontrated with the United Earth Space Probe Agency and other scientific organizations from other planets (the Vulcan Science Ministry, for example, and a few others) to become the go-to boys for any and all scientific/industrial/diplomatic operations in Federation space, and they got so good at it that pretty soon they were the only show in town.
After a few decades of this, Starfleet has so thoroughly revamped itself (even gotten snazzy new uniforms that look more astronauty than navy) that it is no longer unusual for starships to have the family members of their crews on board; it has gone from a military organization to a scientific merchant marine--a "scientist marine" if you will--whose combat role is on an "as needed" basis.
