To keep things over on the "eastern" side of the Alpha Octant a while longer, it might be worth taking a closer look at how technology helped drive the history of the Inter-Stellar Concordium - be it in the "standard" timeline, as well as in the "Mapsheet P" timelines noted in the previous post.
-----
The five species which founded the ISC (
shown here) evolved in a relatively small region of space, thousands of parsecs from any other warp-capable species. Four of these species - the humanoid Veltressai, the reptilian Pronhoulites, the felinoid Korlivilar, and the "turtle-dolphin" Rovillians - have home worlds in
Federation and Empire hex 5910; the Q'Naabian (humanoids, yet breathing an oxygen/chlorine atmosphere) home world is in
F&E hex 5810.
While these five species each developed non-tactical warp drive at or around the same time, the version of NTW they each developed was short-ranged and unreliable. This effectively kept them cooped up in a contested region of space known as the Resource Worlds, over which all five would squabble for close to two hundred years.
The onset of W-era tactical warp drive changed things in two key ways. As "warp-class" weaponry lagged a few decades behind, it became impractical to continue to fight over the Resource Worlds while still armed with "sublight" weapons. Not least since thousands of new star systems, far beyond the Resource Worlds, were now within reach. Fortunately, by the time the five species deployed "warp-driven" ships armed with phasers and various plasma-based heavy weapons, this new reality was beginning to sink in: there were more than enough New Worlds to go around.
Yet despite a series of treaties bringing the Resource World wars to an end, it took time for trust to build between these five former rivals. It took even longer for the first steps towards economic, cultural, technological, and ultimately political integration to be taken, turning the Inter-Stellar Concordium from a protocol into an alliance, and then from an alliance into a government.
Even so, by the time a series of "two-prong" Y-era hulls had been drawn up to serve as the backbone of a unified ISC Navy and Police, the five species had taken a key lesson to heart: warp equals peace.

One key branching point between the "standard" and "Mapsheet P" timelines is when this deeply-held belief was shattered.
In the "standard" timeline, this took place in Y160, when an ISC ship detected energy flashes from a battle between the Gorns and Romulans, withdrawing before being detected themselves. Shocked that warp-powered species would go so far as to fight one another, the ISC took several years to construct a fleet of "three-prong" ships with which to defend itself; to design a new direct-fire heavy weapon (the plasmatic pulsar device) along with a new tactical formation (the Echelon) to build around it; and to prepare enough mobile bases for them to seize and defend a ring of space at the outermost edge of their Trusteeship Territory at the same time the "western" side of the Alpha Octant was kicking off the General War.
Over in the "Mapsheet P" timelines, however, a fateful First Contact took place with the "lost empire" Paravians in Y110. In this instance, an ISC ship found out the hard way that the deep-seated Paravian hatred of the Gorns extends towards
all reptilian species - despite the Pronhoulites being genetically unrelated to the original Gorn "demons". A cascading set of interactions would lead to the ISC and Gorns being set against the Paravians and Romulans in a series of wars ought over the border provinces surrounding the neutral world of Circle Trigon (in
F&E hex 5109). It would also see the "three-prong" hulls enter service decades earlier, giving the ISC an extended "Middle Years" era compared to what it had over in the historical timeline.
-----
The plasmatic pulsar device is a large (and expensive to arm) heavy weapon. It requires two centerline adjacent option mounts, but cannot be installed on an ISC (or Orion Pirate) hull smaller than Size Class 3.
How the PPD functions differs radically depending on which game system it's used in, but there are some commonalities: it's a two-turn arming direct-fire weapon, which has a "myopic zone" that prevents it from being used at close ranges.
The PPD has a series of wave pulses, that each include "splash" elements (akin to that seen with Paravian quantum wave torpedoes). In
Star Fleet Battles, these wave-pulses are spread over multiple consecutive impulses (4 in a standard load, or 6 in an overload), enabling it to sandpaper off the defences of a target ship. In
Federation Commander, there is no overload function - but the wave-pulses all hit in the same impulse, turning the PPD from a scalpel into a sledgehammer.
Ironically, while the PPD is a difficult weapon to use against the Andromedans in
SFB (which led the ISC to switch to a variety of plasma variants in response to the invasion), this weapon is quite useful against the Andros over in
FC...
The Echelon formation is intended to keep the PPD-armed cruisers and dreadnoughts in an ISC fleet screened by a "gun line" of frigates and destroyers. In practice, getting the Echelon to work on the tabletop varies in difficulty from one game system to another, even before the Andromedans show up to ruin the party.
-----
In the "standard" timeline, the ISC sat out the General War, but was increasingly convinced that the war's outcome would settle nothing. If left to themselves, the "barbarian" empires would be back at each other's throats within a decade, and sooner or later the conflict would spill over into ISC territory.
So, in order to prevent this from happening, the ISC launched a full-scale Pacification Campaign after the General War came to an end. They set up a series of cordons running along the Neutral Zones dividing the former Alliance and Coalition belligerents, while intervening in a series of post-war conflicts which erupted a the war's end (or which had carried on from the war proper).
The most powerful tools at the ISC's disposal during the Pacification were their X-ship Echelons; the most notable ,the
Echelon of Judgement, was perhaps the most powerful squadron of first-generation X-ships ever fielded in the Alpha Octant.
Over in the "Mapsheet P" timelines, however, the ISC did not have the luxury of sitting out the General War; with the Paravians on the side of the Coalition, the Concordium would find itself on the side of the Alliance.
-----
In the "standard" timeline, the Pacification Campaign came to a disastrous end through the onset of the Andromedan invasion. With so many of their ships scattered across a thin line of Neutral Zone hexes from one end of the Alpha Octant to the other, the invaders were able to score a series of devastating blows - and worse, prevent a large number of ships from making it back to defend ISC home space.
Technologically, this would lead to a significant fork in the road. Back home, the main fleet yards would build and convert as many "war" classes as they could, in a desperate attempt to hold the line. Meanwhile, those Pacification forces left orphaned elsewhere in the Alpha Octant coalesced into a series of cantonments, where a range of "system" upgrades were installed that added combat power but at the cost of a lower battle speed.
In the "Mapsheet P" timelines, one could imagine that the "war" classes would appear much earlier, at or around the same time as other "wartime construction" hulls across the Alpha Octant, But having had its hands full during the General War, there would be no Pacification Campaign - but with its "post-war" fleet concentrated in its home space, there would thus be no isolated cantonments in which the "system" refits would need to be installed during the Andromedan War.

This is what an unpainted
ISC heavy war cruiser miniature from Shapeways (in 3125 scale, in Smooth Fine Detail Plastic) looks like:
And a WIP attempt to paint it:
Actually, it might make more sense to show the underside of the ship, so as to explain how the ISC shipwrights built it out from the
ISC destroyer:
The destroyer has a pair of warp engines on the underside of the hull. The
war cruiser adds a third destroyer-sized warp engine and an added superstructure to the underside; the heavy war cruiser has a similar superstructure, but instead adds a pair of frigate engines to the top side of the hull. As the frigate engines block the topmost phasers from having a 360* fire arc, this in effect gives the HCW a more aggressive combat posture.
Which helps against the Andromedans in the "historical" timeline, and perhaps against the Romulans and Paravians over in the "Mapsheet P" timelines.
