The '''''James Madison'' class''' of submarine was an evolutionary development from the {{sclass|Lafayette|submarine|4}} of fleet [[ballistic missile submarine]]. They were identical to the ''Lafayette''s except for being initially designed to carry the [[Polaris A-3 missile]] instead of the earlier A-2. This class, together with the {{sclass|George Washington|submarine|5}}, {{sclass|Ethan Allen|submarine|5}}, ''Lafayette'', and {{sclass|Benjamin Franklin|submarine|5}} 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 ''Lafayette''s in some references.

==Design==

In the early 1970s all were modified for the [[UGM-73 Poseidon|Poseidon C-3]] missile. During the late 1970s and early 1980s, six boats were further modified to carry the [[UGM-96 Trident I|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 Madison''s were decommissioned between 1986 and 1995 due to a combination of [[SALT II]] treaty limitations as the {{sclass|Ohio|submarine|0}} SSBNs entered service, age, and the [[collapse of the Soviet Union]].
