Minor spoilers I guess because fancy weapons. This is my current flagship in the second 0.96 playthrough:
I really wanted to make s-modded Expanded Mags work on a low tech ship that isn't Onslaught, and so I initially made it have 2 Thumpers instead of 1, and in small missiles there were Breaches. Hidden cache later, I switched to this current loadout.
This runs extremely hot, it's very risky to pilot and engage the enemy but oh boy this devours anything that has less hp than you have flux caps. TTK is phenomenal. That said I'd give my left nut to have 100 more dissipation but I know this isn't a high tech ship, I just made it a pseudo high tech cruiser. Again the point of this post isn't optimizitation, I know this is basically a meme build, but it's so incredibly fun and unique I had to share it. Maybe it gets even better when I get more combat skills.
