The Franklin class submarines were built with the Polaris A-3, and later converted to carry the Poseidon C-3. During the late 1970s and early 1980s, select units were further modified to carry Trident-I (C-4) missiles.
In the early 1990s, to make room for the Ohio-class ballistic missile submarines within the limits set by SALT II, the missile tubes of Kamehameha and James K. Polk were disabled. Those boats were redesignated special operations attack submarines and given SSN hull classification symbols. USS Kamehameha was decommissioned on 2 April, 2002, the last ship of the entire class to be decommissioned.
