The Space Station V kit will come with at least 2 Orion III spaceplanes. The question, of course, is how to scale the Orion III with the station, since there is no official size for either. One stated diameter for the SSV is 1,000 feet, which was apparently a size specified before filming. That’d be fine, except that apparently Kubrick thought that the Station looked small compared to the Orion III, and had it optically scaled up by a factor of two, leading to a diameter of 2000 feet.
The Orion III is also officially unsized. However, I believe that a good case was made for a span of 109 feet by Ian Walsh of Stargazer Models, described here. And so, one of the Orion III spaceplanes will be scaled to the station by a ratio of 109 feet/1,000 feet, as shown here:
This is clearly wrong when you look at how the two objects scale against each other as actually filmed. However, it’s actually a pretty good match, and it really looks like this was how the two were originally intended to be scaled:
On the other hand, when they are scaled to a ratio of 109/2,000, they look fairly right compared to the screen.
So at least these two size of Orions will be included, so that the model builder can choose their own scale for the kit. Depending upon production costs, a third or even a fourth intermediate size of Orion may be included (such as one to depict the station being 1500 feet in diameter).
