I know where there is a U.S.-made 18" naval gun projectile.

  Whoa. Did the US ever have a naval gun capable of firing that? If so, on what? Or was it just experimental?

    just in testing. E.g. Iowa class originally was planned to maybe have 18" guns.

      Nevertheless, it persists there on the firing line in Dahlgren, VA.
