This time the contenders are…
Colonial Battlestar (Galactica) Vs. Cylon BaseStar, Vs Scarran Dreadnought, Vs Peacekeeper Command Carrier
Considering the Galactica is outmatched by the BaseStar firepower-wise, i hate to say, but the Galactica would be the first one down, the match would then be between the remaining gargantuan ships…
Cylon BaseStar; thousands of wings of Raiders and also carries nukes
Scarran Dreadnought; massive amounts of firepower, but has a thin walled hull and exposed reactor below the main hull, slow top speed
Peacekeeper Command Carrier; apparently capable of destroying planets (mentioned by Grayza, never seen on the show), shrugs off nukes, however the frag cannons have a limited horizontal firing arc
seeing as a Scarran dreadnought was first taken down by a chunk of stellar matter in the series, and later, in PK Wars, another one was taken down by a wing of interceptors, and another by Prowlers carrying torpedos, that says to me that either the torps carried by the prowlers were massively powerful, or the Scarrans rely more on the fear generated by their presence (nobody would dare attack a Scarran vessel, would they?) and less on actual armor/shielding, if a half dozen Prowlers can take out a Dreadnought, all the BaseStar has to do is send a few waves of Raiders at the DN, maybe arm a few with nukes to make it quick
something tells me it’ll be down to BaseStar Vs Command Carrier, the CC may be able to shrug off Raider attacks, but the limited firing arc of the Frag Cannons mean the PK’s will have to rely on Prowlers to take out the Raiders, while the CC and BS go at it with frag cannons/nukes (similar to the situation with Galactica Vs BS)
it comes down to who has the better armor in this case…
