The Dread Lords are actually quite easy to beat.
First off, don't leave home without a 25% Luck bonus.
Then, if they use tiny hulls, you use small hulls(or larger) with 6-
24 attack.
If they use small hulls, you use medium(or better) hulls with 11-
44 attack.
If they use medium hulls, you use large(or better) hulls with 28-
112 attack.
If they use large hulls, you use huge hulls with 58-
232 attack.
If they use huge hulls, you use huge hulls with Xinathium Hull Plating, Reinforced & Hardened Hull Design, and 117-
468 attack.
If they use defenses on their ships, use fleets to burn down their defenses and get inside that range of attack ratings you need to kill 'em.
The italicized numbers are the the minimum attack ratings you need for a 100% chance of killing a Dread Lords ship, once it's defenses are down(or if it had no defenses at all). The closer you get to this number, the better chance you have of killing the Dread ship.
Until you can get the required ratings, use ultra-fast small/medium hull sniper ships with 4 attack and lots of sensors and lots of engines and keep killing their troop transports. They never use fleets unless they somehow manage to steal your logistics tech.
I've seen DL with 5.5k attack huge hulls on suicidal; which was, until TA, just a little higher than I could get a fleet in a normal game.
One ship???! Wow. BTW, I thought you could get your huge fleets to >8k attack ratings?
My highest fleet attack rating was several games ago with 5 huge ships + 1 large ship together contributing to a rating just over 7.5k.
With a ton of number crunching and a severely huge amount of useless effort, it's
possible to get an attack rating >9k on a fleet of 29 tiny hulls, but that'd require a whopping 24 maximized military starbases. Maybe with TA's special modules, one could get that to over 10k if they actually went and tried to build this system.
Hi!
Yet another alternative to the tie rule with 1-HP defending ship is you need to have in the attacking fleet at least one more ship than that 1-HP defending ship has guns. A fleet of several dozens of tiny hulls with one cheap gun, accompanied by a strong ship to erase DL's defenses (if DLs have more than those tinys can remove with their punny attacks) should be suficient to destroy just about anything the DLs can field. OFC you need to bring that DL's ship down to 1 HP first.

That wouldn't quite work, as far as I see it. On Painful, a DL frigate had 394 attack. 28(57 logistics) x 7hp tiny fighters = 203 hp. They'll get killed. AFAIK, the tie rule cares about maximum hp for each individual ship, and not attack rating or current hp or total fleet hp. The tinys can be useful as a shield for medium/large/huge hulled 'tank' ships, however.
