One of the things I noticed in the core book for the Battlestar Galactica RPG is that the Cylon ships seemed to have several of their statistics skewed. I went through and corrected a few of the secondary numbers and fleshed out a few things, including giving the ships skills. (At the time of the attack, I would assume the combat experience of the Cylon raiders, heavy raiders, and basestars to be sub-par, and this is borne out onscreen. In our campaign, however, they are steadily gaining experience and getting better.)
BASESTAR, MK II
This is the the basestar from the miniseries, through to when the ZOIC models were discontinued for the newer in-house effects team’s basestar (the Mk III, here. We’re assuming the old double saucer from the Razor movie is a Mk I.)
There are, according to Battlestarwiki.org, 864 launching racks for either missiles or raiders (they are interchangeable in the early seasons.) Later MkIII Basestars have missile launching turrets, and less of the the racks are used for fighters (434 total, if I counted correctly [and the above source agrees].)
