Sorry forgot to say - that was a post by Joshua Millyard about 9 months ago, also on his Artstation page which the OP linked to. So it looks like the design was created as a proposed Lakon ship months and months ago, and has recently been rebranded as a core dynamics product. Still unsure if its ever going to be added to the game, but cool as it is, given the 9 month silence from FDev on thhe first (Lakon) iteration of this design, I'm not overly optimistic that these things will ever grace our shipyards screens or SLF hangars.
