The James Madison class of submarine was an evolutionary development from the Lafayette class of fleet ballistic missile submarine. They were identical to the Lafayettes except for being designed to carry the Polaris A-3 missile instead of the earlier A-2. During the late 1970s and early 1980s, select units were further modified to carry Trident-I (C-4) missiles. Together with the George Washington, the Ethan Allen, the Lafayette, and the Benjamin Franklin classes, they comprised the "41 for Freedom."
