The DY-100 is a tough one to think about - my starting point was that this ship was equipped for long-duration flights since it was fitted for a crew in hibernation. Since Earth apparently had no travel beyond our own system prior to the 2060's, it seems that the DY-100's were interplanetary ships. However, in order to progress to a reasonable distance from Earth in only 300 years it seems to me that they must be capable of accelerating to a reasonable fraction of the speed of light - perhaps 20% or so.

Within these limitations I have tried to do is make this design as primitive as possible. This is necessary in order to minimize the difference between Star Treks predicted level of spacecraft development in the 1990's and the actuality which we live with. The Ion drive is perfectly possible, and articles I read in science magazines some years ago indicated that this form of propulsion would be capable of propelling spacecraft at reasonably low acceleration for long periods, thus achieving high speeds. I have no idea if the current state of the technology has changed this prospect, either for better or worse.

The DY-100 model was re-used in "The Ultimate Computer" as the freighter Woden. I have assumed that this ship was not in fact a DY-100 (it was never specifically stated as such), but is rather a look-alike design. This is mostly because it seems silly that a sub-warp vessel would be used as an interstellar freighter in TOS times.
