Based on the latest patch notes it seems like there was sometime blocking it for some players. I think I have ranked up with FWC a few times in the week since patch 2.3.0 and I just scored it tonight. It was my 3rd and final FWC ship. I am currently rank 63. It didn't take nearly this long to earn all the dead orbit ships and shaders. Though there was a change to dead orbit packages (a number of patches/updates ago) which removed an accidental block on 1 of their ships too, the Fermi solution I think. Again, after the update I received all the missing ships quickly.

It's a FWC faction ships only way to get it is to level up FWC and get it from a package.
