My chasing hammerhead works well vs tempests.
Loadout is: 2x assault chainguns, 3x light machineguns, safety overrides, unstable injector. 19 vents 4 capacitors.
It's a variant of the one I usually use set up to chase. I have used it to great effect vs tempests though. You're 30 slower than them with their flux boost, but as soon as they engage they lose it - you don't due to SO. Then you're 20 faster. Then you just ram them and watch them melt under the assault chainguns and machineguns. It's great vs other frigates too. Works ok against destroyers too, but if you're facing a cruiser you would be better off taking out the unstable injector and adding some torpedoes and more capacitors. I keep one of each around because I like the ship so much
Just watch out for their drones, those suckers can take your engines out quick.
-edit- I don't think I have ever tried to fight two of them with this setup though, just one. I imagine two would be rough if you didn't have backup to distract the drones.
