Project history: These are enlarged versions of the Ethan Allen class, all refitted with Poseidon missiles. Daniel Webster is unique in having bow, rather than fin, forward diving planes. Patrol endurance was sixty-eight days, with thirty-two day refit periods between patrols, and a sixteen-month yard overhaul every six years; each ship had two crews.
This group is officially divided into three classes: Lafayette (SSBN616), James Madison (SSBN627), and Benjamin Franklin (SSBN640). The SSBN640s are quieter and have detail improvements. Four more were proposed in the FY65 programme but were not built.
