USS Kamehameha

USS Kamehameha (SSBN-642) was a Benjamin Franklin-class ballistic missile submarine and the only ship in the United States Navy to be named after Kamehameha I, the first King of Hawaii (c. 1758–1819). She is one of only two United States ships named after a monarch.a She was later reclassified as an attack submarine and re-designated SSN-642.
The ship's motto was Imua, which roughly translates from Hawaiian as "go forth and conquer." Another motto used by her crew was Kam do, a play on the phrase "can do."
