Currently working on designs for some larger “small craft”. variant Shuttles, a Marine Dropship, and a larger Marine Assault Carrier. The dropship is 40 dton, and the shuttle variants are 100, 200, and 500 dtons, the assault carrier is probably 400 dtons. What is the range of small craft in your Traveller universe?
There have been multiple classifications for different sizes of ships in the Imperium. So that’s anyone’s guess. I think that most system craft overall will be under 1000 dtons.
