William Tompkins built 307 different model ships at a scale of 1/600. Mr. Tompkins started building his massive collection when he was in his early teens, and he continued to make highly detailed models throughout his lifetime. The fleet of model ships includes a wide array of models that span several decades, if not more, so the collection offers an insightful view of naval evolution over time. A portion of William Tompkins’ fleet of 1/600 scale model ships is on display in the Miniature Engineering Craftsmanship Museum in Carlsbad, CA. This is a 1/600 scale model of the Naval Solar System Cruiser. The model spacecraft is Bill’s own design from 2016, though no real version exists. In theory, the conceptual vessel would use electromagnetic propulsion.
