You mean the Fenris, Zane? That thing is a clunker-junker... quite useless everywhere. The only thing it's good for is swarming corvettes or destroyers... they can't hit anything else with the main beam. The fusion mortar (iirc) is the only good thing on the ship... its not placed particularly well; either the beam or the mortar can hit a ship easily.
The Aeolus is extremely effective against anything AI. No ship stands a chance against the player, save the Big C or Sath... it's quite nearly impossible to destroy either without serious help. I couldn't do it with about 60 ships for fighter escort and 40 ships as bombers. It took forever to disable and disarm everything... the AI killed it self (unscripted Kamikaze) so often... it was sickening.
