I did say that you don't need Capitals to fight remnants, so I thought I'll post that fleeet up first. Not really an end fleet but just a fleet to fight Remnants with. This was in Version 0.9a, back when default battle size was 200. Colonies were introduced and you could plonk down as many industries as you wanted and I wanted to test out the new colony mechanics so all the money went into colonies, so that's how the fleet evolved. At the time I only had Apogee blueprint for cruisers and later for Aurora. Had capitals blueprint but didn't want to use it. Aforementioned colony mechanics meant that multiple colonies in one system were well defended, so I never did fight those massive expedition fleets, instead fighting redacted and generally trading and exploring the universe. Didn't fight pirate bounties. Fleet was based around Apogee and a smattering of personally piloted ships and Tempest and Omen. Mostly deploy the Apogees and a phase ship at the start of battle.

There are 6 Apogees in the fleet. This is the main force. 6 Apogees might seem to be few nowadays, but you can't fit that many ships into a 200 battlesize game anyways. Since the main opponents I have chosen to fight are the Remnants, they usually don't have the big fleets, no more than 300 DP most of the time, so it's enough. In version 0.9a, the Apogee had 0.6 Flux/Damage instead of 0.7, so its now can take 86% of the damage it used so the Apogee is a bit weaker now. Newest version fixes that wierd tilt the Apogee had so it's not all bad. Plasma Cannon as the single large energy mount is the main damage dealer. Other options simply don't have the DPS per weapon. One of the Apogee have a Tachyon Lance, not sure why, it was a while ago. The large missile mount varies between Hurricane MIRV, Locusts and Squalls. I think the Squall didn't do much. The small mounts all seem to have different weapons. Not sure why either, I guess I didn't care. The two rear pulse lasers are there to ward off frigates and fighters. Otherwise the Apogee seems to be effective against remnant destroyers all the way to Radiant. They can absorb and deal a lot of damage relative to their DP, giving them plent of time to retreat when threatened and provide plenty of opportunity for whatever ship I was personally piloting, usually Afflictor or Harbinger.

Since the Radiant is faster than the mediocre speed of the Apogee, there needs to be something that can help chase the Radiant which the Apogee cannot catch up to. It turns out soloing a radiant with an Afflictor is not that good an idea. Sometimes you end up cornering a Radiant at the end with the Apogees and it all works out fine. Harbinger does well enough, but it would be nice to have something to help, which is what the Aurora is there for. Sometimes I would choose to personally pilot it, chucking out whatever officer happened to be on it at the time. Though looking at it, since it is there to chase Radiants, I should had armed it with some missiles but whatever.

Just an alternative Aurora. More of an anti-frigate Aurora since otherwise they run away. Does well enough. Probably not optimal.

Rather Proud of this one. I have a 2 Tempests in the fleet, but an Omen too works wonders. Something is needed to kill frigates and support the Apogees and Omens are different. That Antimatter Blaster is great for personally piloting. It almost faces forward so it's easy to twitch a little and fire it off with seeming disproportionate results. Just remember to be circling clockwise.
