USS Kamehameha (SSBN-642) (called Kamfish by her crew), a Benjamin Franklin-class ballistic missile submarine, was the only ship of the United States Navy to be named for Kamehameha I, the first King of Hawaii (c. 1758-1819). She is one of only two ships of the United States to be named after a monarch.a She was later reclassified as an attack submarine and redesignated SSN-642.

The ship's motto was Imua, which roughly translates (from the Hawaiian) as "go forth and conquer." Another motto used by her crew was Kam do.

Construction and commissioning[]

USS Kamehameha (SSBN-642) in her original configuration as a fleet ballistic missile submarine at her launching on 16 January 1965.

The contract to build Kamehameha was awarded to Mare Island Naval Shipyard at Vallejo, California, on 31 August 1962 and her keel was laid down there on 2 May 1963. She was launched on 16 January 1965, sponsored by Mrs. Samuel Wilder King, and commissioned on 10 December 1965 with Commander Roth S. Leddick in command of the Blue Crew and Commander Robert W. Dickieson in command of the Gold Crew.

Conducting deterrence patrols during the Cold War, Kamehameha's armament as a ballistic missile submarine was 16 Poseidon ballistic missiles plus ten to twelve Mark 48 heavy torpedoes non-ADCAP (advanced capability).

Service history[]

Kamehameha was built in Vallejo, CA. Upon Completion she went on her first Sea Trials, off the coast of California. Afterwards, She went directly to Pearl Harbor, Hawaii, which was her home port until 1970. Although Pearl Harbor was her home port, She made all of her Pacific patrols out of Apra Harbor, Guam, due to her nuclear armament. Early in 1966, Kamehameha joined the United States Pacific Fleet and began her first deterrent patrol on 6 August 1966. After this patrol in November 1966, switched crews, and was soon underway again. It was on her last Pacific patrol that the Blue crew took her to the firing range to fire two dummy warhead Posideons. After that, the Gold crew took Kamehameha through the Panama Canal and on to Charleston, SC, which would be her new home port, until she entered the yards. The yard period started around 1971.

History needed for 1967-1992.

Between 1975 and 1977 she belonged to Submarine Group 2, Squadron 16; homeported in New London CT, and advance-based in Rota Spain.[citation needed] She conducted nuclear deterrent patrols in the Atlantic and 'vicinity' without incident in 1975 and 1976.[citation needed] During September - November 1976, Kamehameha spent time in Charleston, South Carolina conducting SPECOPS with other units, then onto the AUTEC range for qualifications prior to resuming patrol duties after her return to Rota.[citation needed]

Her radio callsign during this period was NKAM.[citation needed]

For much of her operational career, Kamehameha was based at Rota, Spain.

Conversion to attack submarine[]

In July 1992, Kamehameha was converted to a Dry Deck Shelter/swimmer delivery platform, reclassified as an attack submarine, and given hull number SSN-642; her ballistic missile capability was removed and thereafter she carried only torpedoes as armament. Henceforth there was only one crew, and her subsequent missions included SEAL special warfare operations.

Decommissioning and disposal[]

Kamehameha was decommissioned on 2 April 2002 and stricken from the Naval Vessel Register the same day. She was the last of the original "41 for Freedom" fleet ballistic missile submarines in service, and the oldest submarine in the United States Navy at the time of her decommissioning. The wardroom of the oldest submarine in the fleet carried Richard O'Kane's personal cribbage board, and upon the Kamehameha's decommissioning the board was transferred to the next oldest boat, USS Parche (SSN-683).[1] She holds the record for the longest service lifetime of any nuclear submarine—nearly 37 years.[citation needed]

Kamehameha's scrapping via the Nuclear-Powered Ship and Submarine Recycling Program at Bremerton, Washington began in October 2001 and was completed on 28 February 2003.


Kamehameha's sail with fairwater planes, the upper half of her rudder, her bust of King Kamehameha I, a koa plate, bow and spear, and the wardroom monkeypod wood table are stored at Pearl Harbor, Hawaii. Her periscopes have been donated to the Deterrent Park on Submarine Base Bangor, Washington, to become part of the USS Woodrow Wilson (SSBN-624) exhibit.
