Mark 16 torpedo

Anti-surface ship torpedo

The Mark 16 torpedo was a redesign of the United States Navy's standard Mark 14 torpedo in use during World War II. It incorporated war-tested improvements into a weapon designed to be used in unmodified United States fleet submarines. Due to high unit cost and the Mark 14's unreliability issues being solved by mid-1943, they were never put into mass production.
