The Benjamin Franklin-class submarines were built with the Polaris A-3 ballistic missile, and in the early 1970s were converted to carry the Poseidon C-3 missile. During the late 1970s and early 1980s, six boats were further modified to carry the Trident I (C-4) missile, along with six James Madison-class boats. These were Benjamin Franklin, Simon Bolivar, George Bancroft, Henry L. Stimson, Francis Scott Key, and Mariano G. Vallejo.
Due to the loss of in April 1963, this class was designed to SUBSAFE standards and its equipment was similar to the fast attack submarines (SSNs). Previous US SSBNs except the George Washington class had equipment similar to the SSNs.
This class can be distinguished by the fairwater planes' location halfway up the sail; the Lafayettes and James Madisons had the fairwater planes in the upper front portion of the sail.
Two submarines of this class were converted for delivery of up to 66 SEALs or other Special Operations Forces each. In the early 1990s, to make room for the ballistic missile submarines within the limits set by the SALT II strategic arms limitation treaty, the ballistic missile tubes of and were disabled. Those boats were redesignated special operations attack submarines and given attack submarine (SSN) hull classification symbols. They were equipped with dry deck shelters to accommodate SEAL Delivery Vehicles or other equipment.
The Benjamin Franklins were decommissioned between 1992 and 2002 due to a combination of SALT II treaty limitations as the SSBNs entered service, age, and the collapse of the Soviet Union. USS Kamehameha was decommissioned on 2 April 2002, the last ship of the Benjamin Franklin class to be decommissioned.[1]
The sail of George Bancroft is preserved at the Naval Submarine Base King's Bay, Georgia. James K. Polks sail is on display at the National Museum of Nuclear Science & History[2] in Albuquerque, New Mexico. Mariano G. Vallejos sail is preserved at Mare Island, California, where she was built. The sail of Lewis and Clark is on display at the Patriot's Point Maritime Museum in Charleston, South Carolina.
