I've not seen any stats for Dalek or Cyberman ships, but one of knasser's documents included stats for various Sontaran spaceships - I think it was in his Miscellany, which is probably still available to download if you can find the link.
To be honest, so little concrete info is given in the TV series as to the capabilities of the ships we see that you've pretty much got a clean slate to design them from scratch. However, the vehicle rules in DWAITAS are so light that I'm not sure that playing out ship-to-ship combat would be a particularly fulfilling experience - I've not tried it though, so I may be wrong! You've probably already seen the other thread discussing using the vehicle creation rules from Rocket Age, which are slightly more developed than DWAITAS.
Has anyone made stats for cyber ships and dalek saucers for vehicle vs vehicle combat? Garrett
It depends what you want the stats for - for ship-to-ship tactical battles or for general purpose story-telling.
If I needed to run specific battles with my group as part of the drama I'd use the mass combat rules in UNIT:Defending The Earth Sourcebook and cobble some stats together. You could also cannibalise rules Traits and other stuff from the Time Traveller's Companion and other sourcebooks. Bear in mind that the diffference in Techology Levels would play a significant part in battle (Daleks TL 9, Cybermen TL 6).
