Okay, so since I can't find any info on this at all, I must be missing something.

How do you destroy this thing and keep Doomsday alive? Actually I want him to die, but... you know, need him alive. I actually cant seem to destroy this thing. The Broadsword is a beast against fighters, surprisingly, however the endless lock time for the depot makes this basically impossible. One torpedo isn't enough, and I can't get away quick enough from flying into roughly 4K distance to make it back out, recharge, and get back in again,not to mention the other whatever that is.

Anyone have any tactics that worked the first time in or anything?

OKay, well, no way to keep Doomsday alive, but I did find a way after letting him Leeroy Jenkins the depot. Just flew around to the other side of the destroyer so it was between me and the supply depot and took it out first with one torpedo (probably was weakened by flak from the depot actually), then did two runs in after letting shields recharge. Boring wait, but easy tactic. Thankfully doomsday was rescued so it didn't matter, and the commander actually scripted her anger at it, so I guess nobody expected his dumb ass to succeed.
