I was able to reach @j0nes on this forum, and he provided me with the files for his old LHD, and he gave me permission to upload a derivative. So here's a standalone LHD, if you don't want to load all of CUP for it. https://steamcommunity.com/workshop/filedetails/?id=1737598604   I have also uploaded a combo of the Atlas LHD with my own F-35 port: https://steamcommunity.com/sharedfiles/filedetails/?id=1738092921   This updated version now shows up in the 3d editor in the same place as the carrier and destroyer (static ships) - no text editing of a mission file is needed to get it in.
This now uses the BI system for multi-part ships instead of the old spawning script: 
The result is you can click and drag it around the edior, and see the 3d model follow it
You can also place aircraft on the deck without them spawning in flight. I have gotten rid of the old Atlas ship weapons, in favor of the Jets DLC ship weapons. I have added a "No Flag" variant of the ship, and CSAT versions of the ship weapons.     (It is a standalone, but I offer a standalone F35F as well, or a combo of the two)
