The Benjamin Franklin class of
nuclear deterrent
force through the late 1980s. This class and the James Madison class are combined with the Lafayettes in some references.
Design
The Benjamin Franklin-class submarines were built with 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.[2]
Due to the loss of
Thresher-class
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
hull classification symbols. They were equipped with dry deck shelters to accommodate SEAL Delivery Vehicles or other equipment.[2]
Fate
The Benjamin Franklins were decommissioned between 1992 and 2002 due to a combination of
decommissioned on 2 April 2002, the last ship of the Benjamin Franklin class to be decommissioned.[4]
The sail of George Bancroft is preserved at the
Naval Submarine Base King's Bay, Georgia. James K. Polk's sail is on display at the National Museum of Nuclear Science & History[5] in Albuquerque, New Mexico. Mariano G. Vallejo's 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.
