As Dee and her nakama build a colony for themselves in the asteroids, they find a need for a workhorse vessel – and design a class of spaceship which fills all their needs, and then some.
The inital model used for the first trips, the SF-0 “Zip”, had a somewhat different drive configuration than became standard. Once it was rebuilt with the new manufacturing processes available on the V-type asteroids, it was redesignated the SF-1 “Love”. The next ships sharing the design were the SF-2 “Unity”, SF-3 “Imagination”, SF-4 “Napier”, SF-5 “Ludolph”, and SF-6 “Euler”. Most official markings are English written in the Unifon script.
