Weekly reminder that Sunder has pretty much the same shield EHP as the Hammerhead with maxed out capacitors - with the caveat that Hammerhead will never have enough spare OP to max out capacitors, and Sunder will.
Hammerhead, even with its half base flux venting, vents its damage faster. 0.8 vs 1.2 is a lot of vent speed difference. Sure, you can *make* a Sunder vent its damage slightly faster, but at that point, you don't have the OP to use your main weapon slot. I don't compare ships in vacuum, i compare them ~~in atmosphere~~ based on their reasonable builds.
It also has double armor (and 20% more hull), and while 500 is not that much armor, it's still miles better than Sunder, which has only slightly more than a Sarissa.
(Hammerhead is also 1 DP less and rotates much faster, but is 25% slower to accelerate.)
