How do I extract 3D models from Battlefleet Gothic: Armada?

[HELP ME!!!]

Greetings everyone,

I've been recently obsessed with the idea of making a papercraft from Battlefleet Gothic: Armada particularly with the Retribution-class battleship of the Imperium. I tried using Ninja Ripper but after opening it with 3DS Max, something really long was jutting out of ship so I ditched using it. I ripped the ship while it was lost in the Immaterium.

I managed to extract the contents of .pak file with Haoose's "UE4 pak-file unpacker" but I don't know what to do with those uasset files. Then I used "Umodel" to find the ship model and texture but all I found was a 3d model of a fucking teapot. I'm not even sure where the ship is exactly located. I'm guessing that it was in the "Dreadnought" folder. What should I do?

Oh and have a happy New Year!
