....What? The Pharos don't exist for the capital ships with long term missions that expand the Federations territory, they exist for literally everything else.
It, by definition, helps by giving them improved capacity for self sufficiency beyond the easy reach of the Pharos network
We won't be concerned with what goes on behind the Pharos network for a decade yet:
Lacking the facilities to participate in the rebuilding efforts they were assigned to suppressing the surge in piracy caused by the depletion of Starfleet's patrol roster and flying the flag near contested borders with the Tholian Assembly and Gorn Hegemony. They finally entered their second stage of life in the 2250s when a recovered Starfleet turned its attention back to beyond its borders. The Pathfinder Missions were designed to use the Excalibur's range and speed to chart over a hundred light years beyond the boundaries of Federation space.
Our problem is that our fleet is a shadow of what it used to be. Starfleet constructed 68 ships between 2225 and 2240, so combined with the better effective range of warp 8 ships the 2250's seem about right for when Starfleet manages to reach prewar capability. We can't expect to hit that kind of ship output if we're churning out 250,000 ton monsters, though.
Big problem! Combat related! Specialised ships have 3 combat ships for a total score of 3, and 9 half strength that pair up to equal a standard tactically. Rounding, that's 7 groups of 1 power.
Generalist ships are fully tactically capable, and give 10 ships at 1 power. Not only are the generalist ships higher total score, but they are much less vulnerable individually.
That's not how our tactical works out. Being bigger makes you more durable, but doesn't do much for your firepower and makes being maneuverable harder. Our specialists end up tactically questionable when we design them that way to cut cost, not because their mission loadout takes up space that could've been weapons. The Excalibur easily could've been a respectable engineering cruiser had we made different module choices.
And why are you only concerned about emergency response? We're not bigger than OTL Federation because of our emergency response capability, we're bigger because we kept building engineering and science ships that help us build up during normal operations. The vast majority of a ship's time is spent in routine operations, which is why we have (had) so damn many engineering cruisers.
We've also seen the difference between order quantities of small, cheap specialist-ish ships and large generalists in the Cygnus and Sagarmatha, which we respectively got 28 and 12 of. The Sagarmatha is certainly much more capable, but they have the same warp speed so the 28 Cygnus in practice covered vastly more territory than the 12 Sagarmathas.
Bringing up Yet Another point, something that was mathed out by MULTIPLE people now. You can have 9 ships at say 200Ktons or 10 ships at say 100Ktons, BUT the 10 ships will ALL have about 40% less capability in All Areas. Do you really think that 1 extra ship is worth ALL ships having almost HALF the capabilities? With the current mechanics this is how it is. Smaller ships are not worth building. About HALF the cost is just in the Warp Core, Nacelles, Computer, and other expensive items you NEED for all large ships.
This same scaling goes all the way up and down the size charts. Building bigger has a better Cost Benefit Ratio. If you can support building a larger ship it is always more worth building a larger ship. Except where limitations prevent you from doing so, like shuttles and other craft you carry on larger craft.
Ex The Hull and other items cost 45 on this ship, the weapons cost 44.5, Total 89.5
We could have picked a hull 100Ktons larger for only 14 cost more. Less than 1/3 the cost of the Weapons, if we didn't add more to a larger hull. Which likely would have been done. And I'm ignoring the science, that would be higher as well.
And oh, hey looky looky, the Excalibur had a cost of 97.25/91.25 Almost the same cost as this TINY ship. With Much better weapons.
Yeah, and that would be great if this quest was being run by an algorithm and not a human person who presumably doesn't want the quest to exclusively churn out dreadnoughts to maximize modules and durability per cost. I suspect that we won't be allowed to simply keep tacking on weight for optimal cost spend, though.
Every ship we've built at 200,000 tons or greater has been noted as being expensive, even the Kea with a B- in cost. The current cost system doesn't model it, but the intent is clearly that larger ships do actually require significantly more to build.
And how does the Excalibur carry better weapons than this ship which is somehow spending 45 cost on weapons? 45 cost of weapons is what, two phaser banks and three RFLs? This tiny ship has nearly double the alpha strike of an Excalibur?
The idea that we'll be able to get by with a smaller number of large generalists servicing our territory when we previously operated 78 engineering cruisers (more engineering cruisers than we likely have ships in total post-war) doesn't hold up to even cursory scrutiny. If that were the case we wouldn't have built fifty engineering cruisers in fifteen years, and we certainly wouldn't be overstretched with a 150 ships. At best you could argue that the new warp core and upcoming nacelle dramatically increase the effective range of each ship, but I'm pretty sure that also means that we're going to expand even farther.
And how did we swing from "curse those useless bureaucrats, risking the federation by withholding the funds necessary to construct a glorious fleet" to "actually less ships is better, and in fact our current fleet composition is too focused on numbers instead of explorers"? Do people just latch on to whatever happened in the most recent story post and determine their build strategy off of it?
