Gondim, realmente me equivoquei. A DR que NAO conta � a do HULL contra ION CANNONS.

How exactly do ion cannons work?
If the target has shields, ion cannons inflict their listed damage as any other weapon would. Roll damage, subtract the target's DR, and then reduce the target's shield points by the remaining amount. If the target doesn't have shields (or if its shield points have been reduced to zero), then use the chart given under ion cannons to determine the effect of the hit.

Does the DR of a ship's hull work against ion damage?
Hull DR does not apply against ion damage. Once the ion damage penetrates the shields, the ship begins suffering the effects of ion damage.
