Your counter to that sensor boost tornado is interceptors. Not only do nados not have any tank but they didnt fit any tank. They didnt fit any damage mods either. Ceptors will sig tank them and if they catch one it will die.
A malediction has a point range bonus and can go over 5k with a nanofiber internal structure 2, overdrive injection system 2 and dc2 in the lows.
You wont deal any damage but you dont need to deal that much as they have no tank. Just burn at them on warp in.
