If you look at a couple of other screen caps you'll see the Maizaru/Guantanamo, look for the one with the girl looking out a window and look below her bangs, as for the Acshio Types, they seem a little large, either that or they are really close to the camera perspective, I have a feeling they are more likely either huge rural colony ships or supply growing ships, which they would probably need quite a few of if the colony consists of 10 million. The stealth frigate can also be seen in another clip, it might be the same as the one I mentioned above but I can't remember, as for the Yamatoesque ship it kind of reminds me of the Algenicus from the M3 video game.
