An awesome Mk-16 torpedo test fire against a 1,500 ton vessel in Hawaii (1961). The Mark 16 torpedo was a redesign of the United States Navy standard Mark 14 torpedo to incorporate war-tested improvements for use in unmodified United States fleet submarines. The torpedo was considered the United States standard anti-shipping torpedo for twenty years; although significant numbers of Mark 14 wartime production remained in inventory.
