James Madison-class Nuclear Ballistic Missile Submarine

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 initially designed to carry the Polaris A-3 missile instead of the earlier A-2. This class, together with the George Washington, Ethan Allen, Lafayette, and Benjamin Franklin-classes, composed the "41 for Freedom" that was the Navy's primary contribution to the nuclear deterrent force through the late 1980s. This class and the Benjamin Franklin-class are combined with the Lafayettes in some references.
