James Madison-class submarine

Template:Infobox ship imageTemplate:Infobox ship class overviewTemplate:Infobox ship characteristics

The James Madison class of submarine was an evolutionary development from the Template:Sclass 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 Template:Sclass, Template:Sclass, Lafayette, and Template:Sclass 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.

Design

In the early 1970s all were modified for 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 Benjamin Franklin-class boats. These were James Madison, Daniel Boone, John C. Calhoun, Von Steuben, Casimir Pulaski, and Stonewall Jackson.<ref name="Conways p612">Gardiner and Chumbley 1995, p.612.</ref>

Fate

The James Madisons were decommissioned between 1986 and 1995 due to a combination of SALT II treaty limitations as the Template:Sclass SSBNs entered service, age, and the collapse of the Soviet Union.
