Infinite Space Insights: Building the Ultimate Custom Capital Ship Fleet
After thousands of playthroughs in Infinite Space III: Sea of Stars, there was one question above all others that puzzled me: What is the best fleet of four capital ships you can have in the game? It did not take me very long to realize that such a fleet would need a balance of speed, agility, firepower, and defenses. Eventually, I settled on having one each of a Terran corvette, a Zorg corvette, a Garthan frigate, and a Calatian destroyer as my capital ships - I never deploy fighters in combat during regular gameplay, but the two fighter slots in the fleet are free, so I could choose from any faction regarding those, although the Zorg and Garthan fighters are generally considered the most useful in custom battles.
Above, from top: This custom fleet contains one each of a Terran corvette, a Zorg corvette, a Garthan frigate, and a Calatian destroyer - all of which have been upgraded with the best weaponry and technology the game has to offer.
All four capital ships in this fleet are fitted with Temporal Flux Shields (for maximum defense), Reactionless Thrusters (to maximize agility and speed during combat), Plasma Coil Cloakers (for increased stealth), Sardion Maximizers (which provide the greatest increase in accuracy and fire rate), and Multibot Repair Drones (which are the most effective means of repairing hull and component damage). In addition, with the exception of the Calatian destroyer, each capital ship also carries a Signature Projector (the most advanced ECM system for deflecting incoming missiles) and a Tachyon Ray Gun (the best weapon to use against fighters). The first capital ship in this fleet will be a Terran corvette with a Nova Cannon for its primary weapon. This makes it a highly effective sniper at long range, especially against larger, slower-moving targets. A Zorg corvette armed with a Particle Vortex Cannon (the only primary weapon that is effective at long range at all ranges) will occupy the second capital ship spot, while a Garthan Frigate loaded with two Cobalt Torpedo Tubes (the best homing weapon by far, with its high muzzle velocity) takes up the third such slot. Finally, the last capital ship will be a Calatian destroyer carrying four Proton Blasters for shooting down fighters and missiles at short to medium range.
Usually the best way to use most of these vessels in these configurations is in a sniping role facing the target(s) head-on, with the Calatian destroyer positioned near any of the other three capital ships to act as an "iron dome" against fighters and missiles. However, it's also possible to trap the opposing fleet in a pincer movement with the force composition I've suggested, by having the Terran corvette and Garthan frigate lurk behind the target(s) with their cloaking devices (only decloaking to attack, before reactivating their Cloakers if they are targeted), while the Zorg corvette and Calatian destroyer lure them forward into a trap. Although this tactic can also be attempted with other capital ship types and loadouts, I've found this particular one to be the most effective of all for this approach. This strategy also works with just the Garthan frigate and Terran corvette positioned ahead of and behind the target, respectively.

Against Yellow Kawangi Dreadnoughts, however, the Zorg corvette and Calatian destroyer lack the long-range punch (in terms of raw alpha strike damage at such extreme ranges, as opposed to damage per second at closer ranges) to take down these behemoths with sustained fire, even with cloaking devices installed, so the respective loadouts for the Terran corvette and Garthan frigate are the only viable options in this specific scenario, where the Dreadnought's Temporal Flux Shield and Multibot Repair Drone give it nigh-impregnable defenses, bolstered further by four Graviton Disintegrators (two on each side) and a rear-facing Proton Blaster. Those weapons, however, cannot outrange a Nova Cannon (which the Kawangi dreadnought has by default), to say nothing of the even longer-ranged Cobalt Torpedo Tube (the latter of which is standard equipment only on the Damocles, although you can't encounter that particular vessel and a Yellow Kawangi Dreadnought in the same playthrough, or even have them face each other in any custom scenario).

Even so, the force composition I proposed in this post may turn out to be the most effective one there is in a custom battle. It is possible to create a similar set of loadouts with the same capital ship classes in a regular game, but there are a few necessary differences: replacing the Cobalt Torpedo Tubes with Multi-Missile Launchers (which do not require the presence of the capital ship Damocles on the map to obtain), downgrading the Sardion Maximizers to Sardion Optimizers at best on most or all of the capital ships, and even then, the Zorg, Calatian, and Garthan home systems must all be present on the map to get anywhere close to the loadout I have suggested.
In short, this fleet composition and loadout combination I have suggested may just be the most overpowered one (assuming no duplicates of any capital ship class are being used), although there are a few that come close. The most promising alternative combines a pair of Terran destroyers with the Kestrel and a Muktian destroyer, with the Terran destroyers carrying 3 Multi-Missile Launchers each while the other two capital ships have two such Launchers each - but even with Proton Blasters filling all the remaining hardpoints on those capital ships, this fleet still uses two of the same unit (in this case, a Terran destroyer) from the same faction. So if you absolutely must avoid using the same unit more than once in a custom fleet, this setup is off the table, but the one that's the primary subject of this post most definitely isn't.
