Yamashuto
Given the size of this ship, and the compliment, you should probably replace the Sakura medical center with a Star Army Standard Hospital Center since this ship has to serve as the facilities during the construction phase.
What is the hull constructed of? You haven't listed the frame and hull, the SP for the ship depends on what material.
I would also add a couple of Orbital Geological Survey Platforms to the compliment since its designed to survey the geology of a planet from orbit.
Cryostasis
First why are the pods filled with Nekos? Colonies are typically filled with Civilians. Further more Yamatai it appears has moved beyond freezing people, I would just call it a Stasis Bay, The Ke-F8 has stasis rooms and the tubes are given a basic description.
Kaseron Class Heavy Lifter
Armor / Hull is not defined.
Nomenclature is not correct, Ke for Ketsurui
Y1, Y2, and Y3 are already taken so it would be Ke-Y4
Missing date of service
