Kongou is a very old buddhist term for strong metal/material. Japanese refer diamond as Kongouseki (kongou stone).

Kongou is just named after Kongousan (Mt. Kongou), a geographical name just like how Americans name their ships from states like North Carolina or South Dakota.

No reason to be thinking too hard about this :)
