All those ships were 41 for Freedom SSBNs when...apparently the Navy felt like picking random names out of history books (excepting the first USS Tecumseh which...I simply can't say, especially since US military intelligence highly suggested and was under the assumption otherwise that all native tribes were actively allied with the Confederacy, and indeed quite a few were).
I don't know that the names were "random," but overtime you can see a trend towards greater ethnic inclusion in the honor of names for major naval vessels. At the risk of being polically incorrect, there is a faint hint of "tokenism" in having one African American, two American Indians, one Hawaiian, one Mexican American, and one South American in the list of names. Ascribing the theme of freedom, as idealize in the American ethos, to some of the historic figures is a bit of stretch. Tecumseh wanted freedom
from the US. Kamehameha achieved fame by conquring the other Hawaiian islands, it did make him the "founding father" of the unified Kingdom of Hawaii, but the group that benefited the most was the noble families of the Big Island, traditional noble families on other islands were supressed. We could fill a multivolume series of books on discussing how Confederate gerneals fit into the theme of "freedom".
