Can you list all current ships planned to either carry the snub, or have a future module planned to carry the snub?

Just what's currently announced, since future-modules are to be determined in the future: Constellation-series (excluding the Taurus), 890J, Carrack, Idris, and the Javelin. There could definitely be more choices later, but we won't really be able to make those decisions until the base ship is already built out and flyable.
