@Mytran - I think you are referring to the tube structures behind the giant grill that goes to the orange glowing end? Currently 10.7m. You can see that it still could be kinda short as it doesn't line up with the reference screenshot. I'm hoping to find a better screenshot that is more inline with that part as I understand it to be a forced-perspective piece.
However, I'm thinking that there are engine rooms in both hulls, so the ultimate length of that machinery will probably vary for practical purposes
