The Vengeance-class cruiser, sometimes erroneously known as the Vengeance-class frigate, was a warship in the Zann Consortium's fleet. It was unusually armed, with a primary battery consisting of two heavy shield-penetrating mass driver cannons - massive projectile weapons that fired warheads that automatically went through the shields of enemy warships and assailed their armor. It had a secondary battery of fifteen turbolasers, which were used to engage smaller capital ships.
