After the shortcomings identified in the recent Full Thrust battle report. The Colonials have gone back to the drawing board. The new design now has a bolstering of the Battlestars hull and armour plating, upgrading some weapon systems, removing several fighters and adding a tone of Point Defence Systems (for a total of 18!). Should be able to stand its ground now against a Cylon Basestar.
The Cylons, for their part, have hacked network systems and learned that a new carrier class ship is on the drawing board. As such, they have updated their design on the Basestar, adding more PDS as well (for a total of 10) in order to face increased long-range fighter groups.
