The Terran Federated Navy (TFN) Super-Dreadnought model was created by Todd Dillen, based on Jack Southerland's Starfire artwork in the Classic Starfire (Third Edition) products. The TFN Super-Dreadnought is a ubiquitous design that can be seen in the Starfire supplement Stars At War on pages 4, 12, 47, and 138; and in the supplement Crusade on pages 1, 9, 16, 21, and 73.
