From the preview:
After a successful launch last month, players will be looking toward October when they can increase their fleet options for Star Trek: Attack Wing with the first wave release of expansion ships. One ship players have been eagerly awaiting is none other than Deep Space 9’s nimble starship, the U.S.S. Defiant.
Like all ships released to date, the U.S.S. Defiant expansion pack allows a player to run the unique version of the ship (at 24 Squadron Points) or the non-unique version of the ship (at 22 points). The named U.S.S. Defiant gains one shield as well as the special ability to convert all of the opponent’s Critical Hits to Hits when defending– representing the ablative armor of the U.S.S. Defiant.
