From a review of the Wiki, it seems these are going to be quite a bit smaller than comparable units in the CGW era.
- Acclamator. By stats, it feels vaguely VSD-like, but it's quite a bit smaller than the VSD at 752m vs the VSD's 900m. Indeed, halfway to a GSD's 600m. So between a VSD and GSD in size? Maybe almost exactly the size of a Quasar Fire? EDIT: Or maybe the Assault Frigate Mk2 - at 700m, that's basically exactly the right size. And it's chonky like the Acclamator, too, so that'll be my guess for the moment?
- Venator. 1137m - puts it closer to a VSD in length vs the ISD's massive 1600m. (Of course, the Liberty-class is spot-on 1200m, so I guess about that big?) ...course, we know nothing about this beyond the wave 2 teaser, so who knows...
- Munificent. 825m - bigger than an Acclamator, but still smaller than a VSD.
- The Providence and Recusant both have two versions that appeared - smaller versions in the 1000m/1100m range, and larger versions in the 2200m/2500m range. Wonder which FFG will go with, and the resulting models...
