For quite a while now fans have argued about the size of the Klingon Bird-of-Prey. In the original films it was portrayed as a small ship with a size of around 110 metres, however, when The Next Generation came out the Bird-of-Prey appeared in a few epidodes in a completely different scale, the most obvious offender episodes been ‘The Defector’ and ‘ Yesterdays Enterprise’. This was attributed to this new Bird-of_prey being a different class, Bernd over at Ex Astris Scientia hasa good article regarding the scaling and classes:-
Recently a debate started due to my size comparison charts regarding the size of the Bird-of-Prey, more sepecifically the Kvort variant which Ex Astris Scientia believes in the episode ‘The Defector’ has to be atleast 700m in length for the scene to work. This has been widely accepted as fact. The thread can be found here discussing the size issue:-
So, I decided I would create the scene in 3D to help clear this up once and for all. It was my intent to create the scene with a 350m Bird-of-Prey and a 700m Bird-of-Prey. The first thing I had to do is scale the models to the correct sizes.
Once I had the scales figured out I went about placing the ships in the correct positions to get the same image as was seen in the episode. I did not scale any of the ships, I simply moved them in relation to the Camera until I got the next image:-
As you can see, this scene is pretty close to how the episode looked, this is using 350m Bird-of-Preys, ofcourse, people have argued that the Bird-of-Preys would need to be sitting on top of the Warbirds for this shot to be possable, so I decided to rotate the scene so you can actually see the distances between the ships:-
At this point I decided not to even bother recreating the scene with a 700m long Bird-of-Prey as it seems pretty obvious that a 350m long Bird-of-Prey is more than large enough to create the scene as was seen in the episode. I’d conclude from this that there is no evidence to support the idea of a 700m long Bird-of-Prey.
Since I posted this people have said that the Bird-of-Preys are still to close to the Romulan warbirds and thus the length in the DS9 Technical Manual are the true numbers, so, I recreated teh scene with 700m long Bird-of-Preys, as you can see from the Tactical view below, the rear Bird-of-Preys are at a much more reasonable distance, however, the ship in the foreground now has its wing almost wrapped around the Enterprise for the scene to work, which is obviously far to close. I’d deduce from this that the ships in the scene from ‘The Defector’ had to be the 350m long ships.
