You can check out linked Spectrum thread but here are John Crew’s posts about that:

Hey,

We’d planned to talk more about this at IAE (as thats generally where we give big updates across manufacturers) but a lot of people are discussing this very topic at the moment so want to add some clarification in advance:

There are no current plans to have a base building module for the Galaxy, that doesnt mean there never will be but there is nothing concepted, planned or in the production schedule. The Starlancer BLD will be the ship you can build Large structures with when base building is available ingame. The only confirmed module in addition to the ones on the pledge store is the Manufacturing module, the general rule of thumb for all things vehicle is unless its on the pledge store or available ingame treat it as speculative. The Perseus is the next RSI capital ship in production (instead of the Galaxy) purely down to the greater percentage of shared assets with Polaris.

Hope that clears up some confusion around the matter and if scheduling/filming format allows we will discuss more around IAE.

Just to try and add some extra information as the phrasing for aspects was perhaps not as clear as it could’ve been, I’m aware that the news is not as hoped but I’d prefer to update now than keep people in the dark until the Galaxy releases.

1. Emphasis on no current plans, this does not exclude that there were plans in the past (as inferred at CitizenCon 2953) or that there could be again in the future, there is simply nothing right now.
2. The way base building works with drones now does not lend itself to the Galaxy’s module layout due to their size and navigation requirements and if one would exist in the future, it would be significantly divergent than from what shown on that slide regardless
3. The “confusion” comment was in regards to discussion about why we did not discuss it during CitizenCon 2954 and the ships status, not over past statements existing or not.

On a completely unrelated note, here (32:44) is Todd Pappy talking about Galaxy being able to build small to large structures during last year’s CitizenCon and here is the relevant slide from that presentation.
